How to do this one? please help me!
The angular position of a point on the rim of a rotating wheel is given by theta = 3.31t - 6.48t^2 + 1.20t^3, where theta is in radians and t is in seconds. What are the angular velocities at (a) t = 3.56 s and (b) t = 9.39 s? (c) What...

1. At one point in a pipeline the water's speed is 3.00 ms and the gauge pressure is 5.00 x 104 Pa. Find the gauge pressure at a second point in the line, 11.0 m lower than the first, if the pipe diameter at the second point is twice that at the first.

(1 point) Consider a system with one component that is subject to failure, and suppose that we have 100 copies of the component. Suppose further that the lifespan of each copy is an independent exponential random variable with mean 25 days, and that we replace the component with a new copy immediately when it fails (a) Approximate the probability that...

A cylindrical blood vessel is partially blocked by the buildup of plaque. At one point, the plaque decreases the diameter of the vessel by 72.0%. The blood approaching the blocked portion has speed ?0. Just as the blood enters the blocked portion of the vessel, what is its speed ?, expressed as a multiple of ?0?

The potential due to a few charges at one point can be found by adding the potential due to each individual charge. It is easy to add them, because potential is a scalar and can be added directly (without considering directions and angles). True or False? The total potential energy due to a few charges can be found by adding...
