What do we call an object displaced by an unbalanced Force,
Accelerated object,
And we also know that,
Due to acceleration, An object displaces.
But I'll use Newton's 1st law to prove it,
Which is, An object will remain in rest or in uniform motion until it is compelled by an external Force.
As per the his law,
The cat will remain on the dashboard of that moving car until it is compelled by Air Force (external Force).

D. Microwaves use radiation, hence the “wave” in microwave
Answer:
a)
125.6 rad/s
b)
25.12 rad/s²
Explanation:
a)
t = time required by the fan to get up to final operating speed = 5 sec
w = final operating rotational speed = 1200 rpm
we know that :
1 revolution = 2π rad
1 min = 60 sec
w = 
w = 
w = 125.6 rad/s
b)
w₀ = initial angular speed = 0 rad/s
α = angular acceleration
using the equation
w = w₀ + α t
125.6 = 0 + α (5)
α = 25.12 rad/s²
It depends on the direction in which the shell is launched. The time can be anything from 3.6 seconds to never.
