Answer:
The angular velocity of the propeller is 2.22 rad/s.
Explanation:
The angular velocity (ω) of the propeller is:
Where:
θ: is the angular displacement = 10.6 revolutions
t: is the time = 30 s

Therefore, the angular velocity of the propeller is 2.22 rad/s.
I hope it helps you!
Answer:
a) 0.040625 m
b) 5.02272 J
Explanation:
k = Spring constant
x = Stretched length
F = Force
a)


Extension of the spring would be 0.040625 m
b) Work done in a spring

The work done by the shopper to stretch this spring a total distance of 8.00 cm is 5.02272 J
To find momentum you multiply the mass and velocity.
91 × 7 = 637 kg-m/s
Answer:
The US Environmental Protection Agency (EPA) sets limits for exposure to x-rays and gamma rays in part because it recognizes that this form of radiation can cause cancer.
