A golf ball with a mass of 45 g is dropped from a height of 1 m. From last semester, you could figure out that its velocity right before it hits the ground is .44 m/s.

J. j. thomson’s experiment disproved the theory that an atom

Which lists the pairs of plates in order from least to greatest in terms of the work done to move the electron?

The drag force, fd, imposed by the surrounding air on a vehicle moving with velocity v is given by fd = cdaρv 2/2 where cd is a constant called the drag coefficient, a is the projected frontal area of the vehicle, and ρ is the air density. an automobile is moving at v = 80 kilometers per hour with cd = 0.28, a = 2.3 m2, and ρ = 1.2 kg/m3.
