Explanation :
It is given that,
Potential energy, 
Power dissipated, 
We know that the power dissipated is given by :

I is the current passing through the phone.



or
I = 0.018 A
Hence, the current that passes through the phone is (1) 0.018 A.
D. Nucleus because it is not a part of the group.
Answer:
If F is a constant, we can take f = 1
f = m×a
ma = 1
therefore we can say that force is hence proportinal to the product of mass and acceleration.
5.91(approx) seconds just divide velocity by acceleration
Answer:

Explanation:
In a uniform circular motion, since a complete revolution represents 2π radians, the angular velocity, which is defined as the angle rotated by a unit of time, is given by:

Here T is the period, that is, the time taken to complete onee revolution:

Replacing (2) in (1):
