Answer:
Net force exerted on the radio is 27.5 Newton.
Given:
Mass = 5.5 kg
Acceleration = 5 
To find:
Force exerted on the radio = ?
Formula used:
F = ma
Where F = net force
m = mass
a = acceleration
Solution:
According to Newton's second law of motion,
F = ma
Where F = net force
m = mass
a = acceleration
F = 5.5 × 5
F = 27.5 Newton
Hence, Net force exerted on the radio is 27.5 Newton.
Answer:
Option C, increases and decreases
Explanation:
When an object making noise approaches you, the wave frequency increases leading to a higher pitch. Conversely, when it moves away from you or retreats, the wave frequency decreases leading to a lower pitch. This can be observed in ambulance sirens.
<u>Answer</u>
C.) 1.0 x 10^2 Newton’s
<u>Explanation</u>
The Newton's second law of motion states that, the rate of change of momentum is proportional to the force producing it.
∴ F = (mv- mu)/t
Ft = mv - mu.
The quantity Ft is called the impulse.
Ft = 0.30 Newton seconds
but t = 3.0 x 10⁻³ seconds
Ft = 0.30 Ns
F × 3.0 x 10⁻³ = 0.30 Ns
F = 0.30 / (3.0 x 10⁻³)
= 100 N
Answer = C.) 1.0 x 10^2 Newton’s
