There are two main reasons why a bouncing ball rise to a lower height with each bounce: 1) because every time it hits the ground it encounters friction, which slows it down, and every time it rises from the ground it encounters air resistance.
Answer:
A.
Explanation:
momentum depends on weight and speed
Explanation:
alike
no contact with the object itself
they can attract objects
they're between 2 objects
difference
source of foundations
type of forces
gravity is only for huge objects
Answer:
A. you would want to use the 12 ound ball and the 18 mph speed in order to transfer the most kinetic energy
B. KE= 1/2 MV^2 so you would want to maximize both your Mass(weight of the ball) and Velocity(speed of the roll) in order to achive the greatest KE.
C. see image
Explanation:
Full disclosure not totally sure what you are being asked in the last one but I put togethere a rough sketch that is my best guess.
The relationship between the amplitude of the electric field E and the amplitude of the magnetic field B for an electromagnetic wave is

where c is the speed of light.
Using the data of the problems and re-arranging the formula, we can calculate the value of B, the amplitude of the magnetic field:
