This diagram shows three models that represent the gravitational force, F, between objects Effect of Mass on Gravitational Force (F)
F
Model 1
Mass = X
Mass = X
2F
-O
Model 2
Mass = X
Mass = 2x
-
4F
Model 3
Mass = 2x
Mass = 2x
a. Describe how the models represent a gravitational force as an attractive force,

where's the following? you gotta add it to know what the choices are

explanation:

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.

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
