A) a fashionable spike heel has an area of 0.878 cm2. when a 61.4 kg woman walking in this shoe sets her full weight down on the heel, what is the pressure ?

Pressure,

Explanation:

Given that,

Area of the heel,

Mass of the woman, m = 61.4 kg

To find,

Pressure on the heel.

Solution,

The pressure acting on the heel is given by the net force acting on the box per unit area. Its formula is given by :

So, the pressure exerted by the heel of the woman is . Hence, this is the required solution.

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.
