Answer:
The average acceleration of the ball during the collision with the wall is
Explanation:
<u>Known Data</u>
We will asume initial speed has a negative direction, , final speed has a positive direction, , and mass .
<u>Initial momentum</u>
<u>final momentum</u>
<u>Impulse</u>
<u>Average Force</u>
<u>Average acceleration</u>
, so .
Therefore,
Explanation:
Gravitational potential energy
= mgh
= (2kg)(10N/kg)(5m)
= 100J.
Answer:
Line the numbers from smallest to largest the subtract the smallest from the largest numbers.
Answer:
0.625m
Explanation:
Now Velocity of a wave ,V = frequency × wavelength
Wavelength =velocity /frequency
=500/800 =0.625m
Answer:
Core is the layer of the sun is energy transferred between atoms.
