Answer to:
If a rock bounces out of, or is kicked up by another vehicle, is that driver liable for paying to fix any damage to a vehicle behind it even if it displays a message stating "not responsible for broken windshields"? If you can prove that the owner of the vehicle that caused the damage was negligent, you can file a suit and win a settlement for the cost of repairing the damages. The deciding factor here is can you prove the driver or owner of the other vehicle didn't behave in a responsible way to prevent the accident. Say for example the tarp covering on the dump truck wasn't closed.

I've heard that the "50-day moving average" is important when evaluating stocks. What is this? A moving average is just the average price using the last 50 days. The idea is all stocks go up or down on most days. If the stock is currently below the 50 day average, it might indicate it's could go up. It's a pretty weak strategy if you ask me. It's just another fact to consider in the overall decision making process.

On Earth, a day is 23 hours 56 minutes long. If we divide 365 conventional 24-hour days by this figure, we get 366 Earth days (367 in a leap year). So where is this missing day?

Most of our clocks aren't that accurate and we adjust them once or twice a year to compensate for their inaccuracies.

Two appendages allow equal forces to be applied to another object at the same moment. Our numerous fingers provide us with even a greater level of object manipulation. Having two arms allows us to pick up and move larger objects than our more closely positioned fingers would allow....

Answer to:
If a mad scientist could implant a small animal, such as a mouse, into the lung of a much larger animal, such as a sperm whale, would the smaller animal be able to breathe and survive? This happens all the time. We get bacteria and viruses growing in us all the time. It doesn't require a "mad scientist." The breathing of the invading organism is another question. Since little available oxygen can be found inside our bodies, it would have to be an anerobic organism that didn't require much oxygen. These organisms do exist. For instance, in your...

Answer to:
Why do carbonated drinks bubble up furiously when poured onto ice? CO2 is trapped in the drink. When you pop the top off the container that CO2 escapes. Pouring the drink over a glass full of ice agitates the solution thus forcing more CO2 out of solution. It's the same as shaking the bottle before you open it. More CO2 is released causing the solution to spurt or bubble out when opened.

Answer to:
If salt is dropped in water, does it boil faster than water without salt? Water with salt in it will boil slower. That is it will boil at a higher temperature so you will have to wait a little bit longer for it to start to boil. The advantage to adding salt to water in boiling a food, is that the temperature of the boiling water will be higher, thus the food will cook faster.

Answer to:
Will diet soda actually help you lose/maintain your weight as compared to regular soda? It's a simple equation. To loose weight, one must use up more calories than are taken in. Eat less or burn more calories or both. A regular soda has about 150 calories. Most diet sodas have zero or a few calories. It's that simple. We are addressing the caloric balance here and not the nutritional needs of your body. You must consume enough other foods to meet the nutritional...

Answer to:
Is it true that the largest icebergs in the world would take 20 years to melt if they were moved to the Sahara desert? I don't think so. By deffinition an iceberg is a landfree chunk of ice floating in the water. A glacier is attached to land and I'm not considering it as being included in your question. I've been in ships in the northern Atlantic where ice bergs could be seen. The fact that these icebergs aren't seen in more southerly latitudes indicates they melt relatively quickly....

Answer to:
I have recently started seeing floating dark spots. When I read, these spots move with my eye. What are they? Yes, they are most likely floaters. This is caused by changes in the vitreous humor in the eye. This jelly like material can get pockets of fluid in it as it ages. These can cause the individual to perceive a shadow that moves with the eye as it looks around. Seeing a few of these now and then is normal. However, if you see allot of them or flashes of light, it could be an indication of a...

Answer to:
Is there a way to get rid of tiny frogs if your yard is loaded with them to the point they are coming into the house? If the frogs are tiny, I'll assume they are young. Amphibians need water to reproduce. The frogs hatch from their eggs as tadpoles. They spend this stage of their lives in a pond or lake or even a discarded tire with water trapped in it. If you can elliminate the standing water, you can reduce the number of tadpole hatchlings. Obviously you cannot get rid of most ponds or lakes....

Answer to:
How fast does the average rain drop fall in mph? Isn't this like asking what is the average automobile's speed in the United States? By the way the answer to both these questions is 19.37 mph. This takes into consideration only autos with engines running. Parked cars would change this average, but the average speed for plummeting rain drops would remain the same. I don't joke around.

Answer to:
Which will keep you drier, running in the rain or walking? If you run your front, intercepts more drops. Your back get's hit with less drops. Wouldn't the two effects cancel out one another? Wouldn't the answer be you'd arrive at your destination drier. However, the front of your shirt would be wetter, but your back would be drier. I guess you could wring your shirt out in a bucket and measure and compare the two results....

Answer to:
What causes that unique, clean smell that occurs outdoors after it rains? I'm not sure if I buy that answer about bacterial growth. That would mean that bacterial growth of an enormous amount in a very short time. I smell the freshness almost as soon as the rain stops. I think the mere fact that raindrops hit the dust and pollen in the air and removes this debris from the air around us also cleanses the air.

Answer to:
Why does the earth have weather? Simpler yet...We have weather because the Earth's atmosphere is heated differently in various locations thus causing relative "hot regions". Weather tends to equalize the energy.

Answer to:
Why does the sun seem brighter in cold weather? Usually the coldest weather follows after a cold front has pushed through an area. As the cold front passes dry cold air replaces the relatively warm moist air. The reduction in atmospheric moisture allows more of the suns light to reach the surface of the earth. Thus you experience cold temperatures but see the effects of a bright sun.

Answer to:
If Earth is furthest from the sun in July, why is it so warm in the northern hemisphere during that time? Take a strong flashlight and point the beam dirctly downward on to a table top. See the small ring of light? Now tilt the flashlight so the beam is tilted when it hits the table and you see an oblong light pattern. The energy hitting the table is now spread out over a larger area. The same amount of energy from the flashlight is spread over a larger area. The amount of light hitting a...

Answer to:
If most of the sweat glands are in the palms of our hands and the soles of our feet, why do we actually have more water running off the top of our heads? I haven't read this anywhere, but just thinking about your question gave me an answer. Your are right in that there are more sweat glands located in the thick epidermis located on the palms of the hands and the bottoms of your feet. Gray's Anatomy gives specifics and the palms have about twice the density of sweat glands as the forehead. I think the answer is because of the volume...

Answer to:
What would happen if you took evaporation out of the water cycle? If evaporation suddenly stopped, what would happen? The question states evaporation stops. This means energy or heat is not consumed in this process. So, this additonal energy or heat will build up. I didn't see any comment in the question about condensation. If evaporation stops there will be an additonal amount of energy in the form of heat. This will be like the Earth having a heat stroke.

Answer to:
Can drinking water with higher levels of chloride dehydrate, rather than hydrate you? It all depends on the concentration of the Chlorine levels. If you took a handful of dried chlorine and put it in your mouth, it would burn your mouth. This would combine to form HCl or hydrochloric acid and this would absorb any H20 present. This would burn the lining of your mouth. Don't try this. The levels of chlorine in normal tapwater are much lower. This will not cause...

Is rain water safe to drink? You can't make a blanket statement that correctly answers your question...it depends. When water evaporates it is the purest form of water. No contaminants are evaporated with the water vapor. This water vapor forms clouds. When the water condenses and drops as water droplets it still is just H20. But, as the rain drops or snow flake drops through the atmosphere, just about anything...

We're planning to buy a house, but our estimated property tax plus mortgage insurance is only slightly more than our standard deduction, so we do not see much of a tax break. Am I missing something? The interest you pay to the mortgage company can be deducted. If you break down the monthly mortgage or loan payments one makes, the two largest portions are for interest charges and principle. Principle payments are the portion paying off the actual cost of the house. At the beginning of a 25 or 30 year loan, almost all your monthly payment is going towards the interest and very little is...

Answer to:
Can a fish live in a swimming pool? We use chlorine in swimming pools to prevent unwanted bacteria and plants from growning. The chlorine combines with hydrogen to form a weak concentration of hydrochloric acid. Fish don't like hydrochloric acid. It kills them. Even our tapwater we drink has small concentrations of chlorine and other gases that will kill fish. That is why when tapwater is used to fill a fish tank, one...

Why can't most fresh water fish live in salt water and most salt water fish not in fresh water? I don't have a quarrel with most of what the previous answer states. But, we don't need to consume salt to prevent dehydration. When we sweat we loose water and salt and allot of other nutrients. In most cases replacing the water is all that is needed. But in cases of extreme sweating it is beneficial to replace the salt and nutrients too. In answering the question about...

Answer to:
Why don't fish get the bends? I think some clarification is needed here. Humans get the so called "bends" when they are diving in water and ascend back to the surface too quickly. At the air/water surface the pressure is less than when a person is deep under the water. If one spends enough time at a deep enough depth, more gases will be forced into the blood. If one returns quickly to the surface, these gases...

I was told to hold my stocks for a year before selling to reduce the tax I have to pay on gains. Why is this? If your money is in a retirement account, you don't need to worry about capital gains taxes as addressed in the previous answer. But, when considering selling a stock before it has been held for one year, you might be better off at selling the stock at a big profit and paying the additional tax if you feel the stock will be much lower after the one year wait. Nothing is easy and...

What would happen if you took evaporation out of the water cycle? If evaporation suddenly stopped, what would happen? This sounds like a high school homework assignment. No evaporation of water means clouds would disapear. We'd have to get used to rainless sunny days. Yes, it would get warmer too. The evaporation process consumes energy and this energy now would take the form of heat. Next consider all the secondary effects this rise in temperature would have on the Earth's ice caps and sea...

In Toronto more afternoon than morning daylight is gained as winter progresses and the reverse is true in the summer. Why wouldn't there be an equal amount of morning and afternoon daylight gained/lost in both seasons? The hours of daylight decreases in winter and increases in summer.

Answer to:
My shot has a nasty slice. How can I get rid of it? You have to understand what causes the ball to turn in flight. The spinning of the golf ball causes a difference in air pressure on oposite sides of the spinning ball. That is exaggerated by the dimples on the ball. As the ball spins the dimples create friction and a build up in air pressure. For example, if the center of the back of the ball is struct first, the bottom of the ball will...

Is there a standard way to determine how long golf clubs should be for a person of a certain height? No, club length is not directly correlated to a person's height. There are many factors contributing to the correct club length. Basically when the club is swung and makes contact with the ball, the club head should be flush with the ground the ball is resting on. The shaft length varies from club to club too. The club head lie angle varies to compensate for this change. When a person...

Why do lakes freeze from top to bottom? H2O is an amazing compound. It becomes more dense as it's temperature is reduced. At about 4 degrees above freezing (C degrees) it starts to become less dense. This is the fact that explain why the somewhat solid form of H2O, ice, floats on top of water. This phenomenon is caused by the angle between the two hydrogen molecules being 105 degrees. When the crystals are forming they lock...
