Answer:
Explanation:
The magnetic moment of the coil M = current x area of loop
= I x L x L
M = L² I .
Magnetic field = B
Torque = M x B
= MB sinθ where θ is angle between M and B . Direction of M is perpendicular to face of loop
Torque = MB sin90
= MB
= L² I B .
Answer:
Weight
Weight ( ) is a force, measured in newtons ( ). Weight is caused by the pull of gravity acting on a mass, usually near the surface of a planet.
Explanation:
Answer:
The maximum speed of the object is 0.662 m/s.
Explanation:
Given that,
Mass of the object, m = 0.67 kg
Spring constant of the spring, k = 15 N/m
The spring is pulled 14 cm or 0.14 m from the equilibrium position and released.
To find,
The maximum speed of the object.
Solution,
The maximum speed of the object is given by :
........(1)
Where
So,
v = 0.662 m/s
So, the maximum speed of the object is 0.662 m/s.
