What is the speed u of the object at the height of (1/2)hmax? Express your answer in terms of v and g. Use three significant figures in the numeric coefficient.

The speed u of the object at the height of (1/2)hmax is 0.707.

At a height that is half of the maximum height the object will have only half of its initial kinetic energy the rest half is converted to potential energy at this point. so

So, The speed u of the object at the height of (1/2) hmax is 0.707.

The speed u of the object at the height of (1/2) hmax is .

Explanation:

At a height that is half of the maximum height, the object will have only half of its initial kinetic energy, the rest half is converted to potential energy at this point. So,

                                  .

The speed u of the object at the height of (1/2) hmax is .

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.
