Answer: (2) 108 C
Explanation:
Electric charge of 1 coulomb has said to have passed when a current of 1 Ampere is passed for 1 second.
Q= charge in coloumb = ?
I = current in amperes = 0.120 A
t= time in seconds = 900 sec
Answer:
0.05 V/m
Explanation:
For a uniform electric field, electric field strength and potential difference are related by
where
E is the electric field strength
is the potential difference
d is the distance between the two points
Here we have
So, the electric field strength is
Answer:
The forces that do non-zero work on the block are gravity and normal reaction force
Explanation:
In this question we have given,
mass of the wooden block,
angle between ramp and horizontal surface,
in this case ramp is friction less so friction force will be zero and hence work done due to friction force will be zero.
As wooden block is sliding down due to gravity(gravity is pulling the block in downward direction).
so two forces will act on wooden block as it slides down the ramp that are gravity and normal reaction force.
Therefore, the forces that do non-zero work on the block are gravity and normal reaction force.
