Only when the torque is constant the work done is done during angular displacement. So the correct option is d.
Work done by the force is calculated as the dot product of force and angular displacement of the point of application of force. It is equal to the change in rotational kinetic energy of the body.
Work done by a torque can be calculated by taking an analogy from work done by force.
Work done = torque × angular displacement
So work is done by a torque during angular displacement only when torque is constant.
If a torque applied on a body rotates it through an angle ω, the work done by torque is
W = ζ × ω

Answer:
D. both have electrons that orbit the atomic nucleus in a simaler way
Explanation:
the bohrs model electrons orbit in a circular pattern were as the modern atomic model orbit in every which way
The answer is the last option "Respiration"
I only know P and V and P is pressure and V is volume
Answer = 330 m/s
The wave equation is as follows:
Wave speed = wavelength x frequency
The known values are:
Wavelength = 3m
Frequency = 110 Hz
Substitute the known values into the wave equation to find the wave speed.
Wave speed = 3 x 110
Wave speed = 330 m/s
