Answer:
B on edgen
Explanation:
The water in pot X has more kinetic energy than the water in pot Y.
Hi there!
We can calculate linear momentum using the following:
p = linear momentum (kgm/s)
m = mass (kg)
v = velocity (m/s)
Calculate:
Now, we can relate force, time, and momentum with the following:
I = Impulse (kgm/s)
F = Force (N)
t = time (s)
Rearrange to solve for force:
The impulse is equal to the change in momentum. Since the car comes to a halt, all of its momentum is lost, so:
Solve:
**Negative force since the positive direction is towards the wall, and the negative direction is away from the wall.
Answer:
400 Newtons to the right.
Explanation:
You have 300 Newtons that are being applied to the right and you also 100 Newtons to the right. When calculating net force with the forces that go the same direction, you add them. 300 plus 100 is 400. Therefore, it is 400 Newtons or N to the right. Hope this helps!
<span>Correct pairs:
a man jogging in the park --> motion energy (the energy is the kinetic energy of the man, moving with speed v)
a fully charged camera battery --> electric potential energy (the battery is fully charged, so it can deliver electrical energy when the camera is turned on)
a stove burner that’s turned on --> radiant energy (the stove burner emits energy by radiation)
an apple on a tree --> gravitational potential energy (when the apple is on the tree, it has gravitational potential energy equal to U=mgh, where m is the apple's mass and h its height from the ground)
