Answer:
Explanation:
given,
mass of block = 3 kg
spring constant k = 500 N/m
kinetic friction coefficient µk = 0.6
speed of block = 5 m/s
F = µk N
F = 0.6 x 3 x 9.8
F = 17.64 N
using energy conservation
250 x² + 17.64 x - 37.5 = 0
on solving
x = 0.354 m
graph is attached below
Answer:
F = 0
Explanation:
The net force acting on an object is given by the product of mass and acceleration. We know that acceleration is equal to the rate of change of velocity.
Net force,
F = ma
The skier is traveling at a constant velocity, it means there is no change in velocity i.e. acceleration is equal to 0. Hence, the force on her is 0.
Answer:
Induced EMF,
Explanation:
Given that,
Radius of the circular loop, r = 5 cm = 0.05 m
Time, t = 0.0548 s
Initial magnetic field,
Final magnetic field,
The expression for the induced emf is given by :
= magnetic flux
So, the induced emf in the loop is 0.0143 volts. Hence, this is the required solution.
