Analyze the data to identify the mathematical relationship between the amplitude and energy of a mechanical wave. If mechanical wave A has an
amplitude of 2 cm and mechanical wave B has an amplitude of 3 cm, what
will be the relationship between the energy carried by the two waves?
Amplitude
Energy
A. Wave A has about 2.5 times more energy than wave B.
B. Wave A has about 2.25 times more energy than wave B.
C. Wave B has about 2.25 times more energy than wave A.
O D. Wave A has about 1.5 times more energy than wave B.

Anne applies a force on a toy car and makes it move forward. what can be said about the forces acting on the toy car at the moment anne applies the force?

Imagine you are riding on a yacht in the ocean and traveling at 20 mph. you then hit a golf ball at 100 mph from the deck of the yacht. you see the ball move away from you at 100mph, while a person standing on a near by beach would observe your golf ball traveling at 120 mph (20 mph + 100 mph). now imagine you are aboard the hermes spacecraft traveling at 0.1c (1/10 the speed of light) past mars and shine a laser from the front of the ship. you would see the light traveling at c (the speed of light) away from your ship. according to einstein’s special relativity, how fast will a person on mars observe the light to be traveling? a) 0.1c (1/10 the speed of light) b) c (the speed of light) c)1.1c (c+0.1c)

For the car in the picture ,in which direction is the normal force? -into the screen -down -out of the screen -up
