Yes i agree with that tbh beciase i think it does do so
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
Your answer is A. Vibrate in place
Answer:
Height of the image is 9.06 cm
Explanation:
As we know that the person is standing 250 cm from the lens
Now we know that the focal length of the lens is
f = 15 cm
now by lens formula we have
now we know by the formula of magnification
now we have
