Answer:
Output voltage is 1.507 mV
Solution:
As per the question:
Nominal resistance, R =
Fixed resistance, R =
Gauge Factor, G.F = 2.01
Supply Voltage,
Strain,
Now,
To calculate the output voltage, :
WE know that strain is given by:
Thus
Now, substituting the suitable values in the above eqn:
Answer:
217.43298 m/s
Explanation:
= Mass of bullet = 19 g
= Mass of bob = 1.3 kg
L = Length of pendulum = 2.3 m
= Angle of deflection = 60°
u = Velocity of bullet
Combined velocity of bullet and bob is given by
As the momentum is conserved
The speed of the bullet is 217.43298 m/s
When a force causes a body to move, work is done on the object by the force. Work is the measure of the energy transfer when a force 'F' moves an object through a distance 'd'. So we say that energy is transferred from one energy store to another when work is done, and therefore, energy transferred = work done.
