Answer 1

Don't see it...

Answer 2

@Isaiah.Feynman @Destinymasha

Answer 3

There it is !

Answer 4

what do you think?

Answer 5

I know the answer... What are your thoughts

Answer 6

I think A

Answer 7

why do you think A?

Answer 8

or D

Answer 9

Why do you think D?

Answer 10

D because the water is flowing into a dam which with stop the water .
A because once the avalanche slides down the mountain side it stops

Answer 11

? I don't understand your logic for A or D

Answer 12

When you lift a ball into the air it has potential energy. When you drop the ball you obtain kinetic energy. Right? So which of the answers relates best to what I just stated?

Answer 13

Lets look at a simple pendulum swinging from left to right and right to left. Once the pendulum reaches its maxim height it has potential energy, when falling/swinging to the left or right it has kinetic energy.

Answer 14

An avalanche sliding down a mountain side has kinetic energy.

Answer 15

B ?

Answer 16

k=1/2mv^2

Answer 17

depends on the velocity.

Answer 18

Why B?

Answer 19

u=mgh depends on height.

Answer 20

When the motorboat pulls the skier it uses kinetic energy . When it stops its potential energy

Answer 21

an avalanche sliding down the hill has a velocity so therefore it must not be kinetic energy. A sail boat being pushed across the water by the air has a speed/velocity, etc. So look at the equation potential=mgh

Answer 22

potential energy depends on mass gravity and height

Answer 23

if we pull the skier across the water we are exerting a force on her/him.

Answer 24

So the answer is the wind pushing a sailboat?
