The magnitude of the impulse delivered to the baseball by the bat is 8.8 Ns.
<h3>Impulse experienced by objects</h3>
The impulse experienced by any object is equal to the change in the momentum of the object.
The magnitude of the impulse delivered to the baseball by the bat is calculated by applying the following equation.
J = Ft
where;
- F is applied force = 8000 N
- t is time, = 1.1 ms
J = (8000) x (1.1 x 10⁻³)
J = 8.8 Ns
Thus, the magnitude of the impulse delivered to the baseball by the bat is 8.8 Ns.

I am pretty sure it is B....
The frequencies of light that an atom can emit are dependent on states the electrons can be in. When excited, an electron moves to a higher energy level or orbital. When the electron falls back to its ground level the light is emitted.
hope this helped:)

The answer would be D hope it helps and sorry if it is wrong. :)
Answer:
Explanation:
Since the roundabout is rotating with uniform velocity ,
input power = frictional power
frictional power = 2.5 kW
frictional torque x angular velocity = 2.5 kW
frictional torque x .47 = 2.5 kW
frictional torque = 2.5 / .47 kN .m
= 5.32 kN . m
= 5 kN.m
b )
When power is switched off , it will decelerate because of frictional torque .
