While leaning out a window that is 7.40 m above the ground, you drop a 0.600-kg basketball to a friend at ground level. Your friend catches the ball at a height of 1.10 m above the ground. Determine the following.
(a) the amount of work done by the force of gravity on the ball
W = J

(b) the gravitational potential energy of the ball-Earth system, relative to the ground when it is released
U0 = J

(c) the gravitational potential energy of the ball-Earth system, relative to the ground when it is caught
Uf = J

(d) the ratio of the change (Uf − U0) in the gravitational potential energy of the ball-Earth system to the work done on the ball by the force of gravity
ΔU
W=

Would corn syrup, molasses, or pancake syrup make a good lubricant in a car engine? explain your answer.

Pl asaaap ! match the term to the correct description. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. movement that is like a t transfers energy from one location to another 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave

Slab pull” is a type of tectonic plate movement that occurs due to the forces of mantle convection and results in the subduction of the lithosphere true or false
