Steve is whirling a rubber cork, tied with a string to his finger, over his head as shown in the figure. the motion of the cork is similar to the motion of a planet in the solar system around the sun. which force in the solar system is similar to the tension in the string?
a) nuclear force
b) magnetic force
c) gravitational force
d) electrostatic force

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever

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.
