I think this might be the answer, if it is I’ll be very surprised =/
Answer:
α = 3070rev/s^2
θ = 5541.66 revolutions
Explanation:
Given;
Operating angular speed w = 350000 rpm
time t = 1.9s
Angular acceleration = change in angular speed/time
Angular acceleration=350000rpm×1/60 min/sec ÷ 1.9s
Angular acceleration α = 3070rev/s^2
Number of revolutions θ = 1/2 × α × t^2
Since initial angular speed is zero
Substituting the values;
θ = 1/2 × 3070 × 1.9^2
θ = 5541.66 revolutions

Answer:
960 Watt
Explanation:
From the question,
Electric power = Voltage squared/Resistance
P = V²/R ..................... Equation 1
Where P = power, V = Voltage, R = Resistance
Given: V = 120 volts, R = 15 ohms.
Substitute these values into equation 1
P = 120²/15
P = 14400/15
P = 960 Watt
