A pulley has a mechanical advantage of 1. What does this tell you about the size and direction of the input and output forces?

The number of input force is the same as output. ... If it equals once, then both numbers are equal making it the same.Explanation:

Does this helps

The number of input force is the same as output. Formula for MA (Mechanical Advantage) is Input Force/Output Force. If it equals once, then both numbers are equal making it the same. In order to raise MA, you must lower efficiency, something you learn around grade 8. Good luck!

P.S. Direction is the same for both, meaning if you pull something, the object you pull will come towards you.

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.

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge
