The correct answer is:
Let's see why.
1 amu corresponds to the mass of the proton, which is:
if we convert this into energy, using Einstein equivalence between mass and energy, we find:
Now we can convert it into electronvolts:
So, 1 amu = 934 MeV. Therefore, 3 amu corresponds to 3 times this value:
Answer:The Doppler effect is a change in the frequency of sound waves that occurs when the source of the sound waves is moving relative to a stationary listener.
As the source of sound waves approaches a listener, the sound waves get closer together, increasing their frequency and the pitch of the sound. The opposite happens when the source of sound waves moves away from the listener.
Explanation:
Force in Newtons =
(1200)•(the rate of acceleration you want)
It depends on how fast you want to accelerate.
The force applied on the football is 2.15 Newton.
Given the data in the question;
- Mass of football;
- Acceleration;
Force applied; 
To determine the force applied on the football, we use Newton's laws of motion:
Where m is the mass of the object and a is the acceleration.
We substitute our given values into the equation
Therefore, the force applied on the football is 2.15 Newton.
