In tides two things are important. The earth is made of materials that do not distort instantly to the forces applied. The earth rotates faster than the moons orbital velocity; as such the near tidal bulges are dragged away from the moon and transfer energy to it, the far tidal bulges vice...

Shut off the good car before boosting.

Rolling involves energy being stored as rotational KE in addition to translation KE.

Ask yourself. Does it matter how high the projectile reaches? yes or no answer.

You know the sun is 150 million kilometers distant.

The sun is extremely far as such the rays are parallel when they arrive on Earth and as such the wave front is planar, The hole in the clouds acts as a gross point source that the rays emanate from. As for the parallax cited by others... not really from the sun. Parallax from the opening in...

Are you are referring to a rotary lawn sprinkler or Hero's steam turbine type of gadget.

My apologies. To everyone here. Sincerely. As for the mentor that PMed me? Less is better than too much,

Once a person has used envrionmental heat stress monitors in the context of sunny construction sites, hot metal, air and furnace exposure in smelters and steel mills one gets up to date with the recommended health and safety regulations and protective measures to be taken...

The vector for friction is parallel to sliding surface and perpendicular to the normal force N. It is equal to the normal force multiplied by the coefficient of friction. The normal force N is a function of mass, g and the cosine of the inclination angle and whatever other forces that can be...

With all due respect, your post has some erroneous affirmations. You cannot insulate the human body against heat except for extremely short periods. Without a cooling process it is only a matter of time before the inside attains the temperature of the outside. As for absorbitivity and...

If your going to boom classical music... then go for Handel.

Sounds like a typical two stage scuba tank compressor would be fine. Keep the destination tanks in flowing tank of water. The compressors have some cooling fins. http://www.bing.com/images/search?q=scuba%20comressors&pc=conduit&ptag=ACF254CB3D91543C4B6F&form=CONMHP&conlogo=CT3210127 New tanks...

Use a low RPM multipole generator. As for the torque it depends on the electrical load and the power disappation there-in.

The power used by the treadmill? At constant speed with the same user, is the power consumption a function of inclination? How so?
