1. Assume a cubical pot of water 1 m on each side. Heat is applied to the bottom of the pot. Assume the water at the bottom is held at 99 degrees C while the water at the top of the pot is 4 degrees C. Estimate the convective heat flow (using algebraic physics). Step 1: Compute the net...

Well, it does change direction. :) So it's -1 x P (for the new velocity).

1. A bike is moving at X m/s. Its tires are .60 m in diameter. How fast is a point at the rim of the top of one of the wheels moving relative to the ground? 2. v = r omega, C = 2 pi r (?) 3. At first we thought he just wanted angular velocity. Then when we realized that his given...
