Just after leaving the platform, the diver’s fully extended 90-kg body has a rotational speed of 0.32 rev/s about an axis normal to the plane of the trajectory. Estimate the angular velocity N later in the dive when the diver has assumed the tuck position. Model the diver as a uniform rod in the first position and as a uniform sphere in the second.

Explanation:

The diver can be modelled by using the Principle of Angular Moment Conservation:

The final angular velocity is:

Let assume that L = 1.60 m and R = 0.15 m.

it becomes positively charged by charging it

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
