Work = Force times distance
from your "answers" the one that bests fits this equation is weight since this is a type of force
Mass is not necessary the main thing we need is Displacement
As
Or
- Work done=Force×Displacement
The amount of work done is calculated as the force exerted to remove a object to D distance .
Answer:
a) 6.8 Volt
b) 1.21Цm
Explanation:
We are given from the question that
The zero -bias depletion layer width(
) is 0.4Цm
The built in voltage φj is 0.85V
Now to calculate the reverse voltage( 
) that would be required to triple the depletion - layer width.
The depletion - layer width (
) of the diode has the formula
For three times of we have
=> 
=> 
Substituting value of φj
We have
= 6.8 V
The required bias voltage is 6.8 V
The solution for the b part of the question is uploaded on first image
Answer:
0Nm, no work is done.
Explanation:
Work done is defined as the Force per distance meaning force times the distance moved in the direction of the force.
Now the body of mass 50g has a centripetal force acting on it directed towards the centre. Now in actuality the body stays along the circle it doesn't really move to the centre of the circle.
Hence the force doesn't move a distance, and so from the definition of work done;
F×d ; d =0
Hence work done = mv2/r × 0= 0Nm
If you stir the juice it increases the surface area.
