I believe the answer would be Kinetic Energy. Kinetic energy is defined as energy which a body possesses by virtue of being in motion. We weren’t given answer choices so I don’t have much to work with lol.
Answer:
v = -5 m/s
Explanation:
It is given that,
The initial velocity of the ball, u = 25 m/s
We need to find its velocity after 2 seconds in the air.
Let v is the velocity of the ball after 2 seconds. Using equation of motion to find it.
v = u + at
Here, a = -g
v = u -gt
Putting all the values,
v = 25 - (10)(3)
= 25-30
= -5 m/s
So, the velocity of the ball after 3 seconds is 5 m/s and it is in downward direction.

It represents the depolarization of the atria.
<u>Explanation:</u>
The P wave speaks to the depolarization of the left and right chamber and furthermore relates to atrial compression. Carefully, the atria contract a brief moment after the P wave starts. Since it is so little, atrial repolarization is typically not unmistakable on ECG.
In an ordinary ECG, there's three particular waves. The primary wave is the P wave, which speaks to the depolarization of the atria. This happens directly before the atria agreement and drive blood into the ventricles. The following wave is known as the QRS wave.
