Answer:
The speed of the block is 4.96 m/s.
Explanation:
Given that.
Mass of block = 1.00 kg
Spring constant = 500 N/m
Position
Coefficient of friction = 0.350
(A). We need to calculate the speed the block has as it passes through equilibrium if the horizontal surface is friction less
Using formula of kinetic energy and potential energy
Put the value into the formula
Hence, The speed of the block is 4.96 m/s.
Answer:
moving the circuit or the magnet gives the same result
Explanation:
The faraday effect establishes that the temporal variation of imaginative flow produces an electric potential
fem = dfi / dt
the magnetic flux is
Ф = B. A = B A cos θ
suppose for simplicity that the angle is zero so cos 0 = 1
Φ = B A
By analyzing this expression, the change in magnetic flux can converge while keeping the magnetic field fixed and varying the electric field or keeping the electric field fixed and varying the magnetic field.
Consequently moving the circuit or the magnet gives the same result
