Answer:

TRUE

Explanation:According to Faraday’s equation, the induced emf is directly proportional to the rate of change of magnetic flux.

EMF=−NΔΦΔt, where N is number of turns of wire round the coil, ΔΦ rate of change of magnetic flux and t is the time measured in seconds.

Magnetic flux is affected by the field strength and the area covered by the coil, if magnetic field increases the induced electromotive force will increase.

A machinist turns the power on to a grinding wheel, which is at rest at time t = 0.00 s. The wheel accelerates uniformly for 10
sashaice [31]

Answer:

Time interval;Δt ≈ 37 seconds

Explanation:

We are given;

Angular deceleration;α = -1.6 rad/s²

Initial angular velocity;ω_i = 59 rad/s

Final angular velocity;ω_f = 0 rad/s

Now, the formula to calculate the acceleration would be gotten from;

α = Change in angular velocity/time interval

Thus; α = Δω/Δt = (ω_f - ω_i)/Δt

So, α = (ω_f - ω_i)/Δt

Making Δt the subject, we have;

Δt = (ω_f - ω_i)/α

Plugging in the relevant values to obtain;

Δt = (0 - 59)/(-1.6)

Δt = -59/-1.6

Δt = 36.875 seconds ≈ 37 seconds

A 2,000 kg car is parked at the top of a 30 m high hill. what is its potential energy?
Phoenix [80]
The PE for this question will be 588,000 because we take the mass (2,000 kg), multiply it by 9.8 which is Gravitational Acceleration and then multiply that by the height (30 meters)
