Answer:
Using Faraday's law;
ε= -N ∆ψ(B)/ ∆t;
∆t= -N ∆ψ(B)/ ε
Explanation:
Using Faraday's law; Faraday's law state that the induced emf is directly proportional to the rate of change of time of magnetic flux
ε= -N ∆ψ(B)/ ∆t;
Where ε= induced EMF, ∆ψ(B)/ ∆t is the rate of change of magnetic flux, ψ(B) = BA cos θ
θ= the angle between the magnetic field B and the normal surface area.
We can also calculate the direction of induced magnetic flux. At first, the field is perpendicular to the plane of the loop,the loop can rotate about either an horizontal or vertical axis passing through the mid point
Well, isn’t v=d/t, then by making subject d, d=vt, turn 3 hours into seconds, 1hr=3600sec, hence 3hr=x, cross multiply and you would have converted it into seconds, then put it into your equation of d=vt
Answer:
1.70 J
Explanation:
The heat dissipated is the difference in the kinetic energies.
This is given by
and 
are the initial and final velocities.
With <em>m</em> = 0.175 kg,
The negative sign appears because energy is lost.
