Every particle of mass is attracted to every other particle of mass. The magnitude of the force between two objects is proportional to the product of their masses, and inversely proportional to the square of the distance between them. The direction of the force is along the line between their centers.
(NOTE: Newton's 3rd law of motion tells us that gravitational forces always come in pairs. Between two objects, there are two forces ... one in each direction. Their strengths are equal ... Your weight on Earth is exactly equal to the Earth's weight on YOU.)
Answer:
It is an instrument which increases the amount of force available to a single hypothetical person.
Examples;
Levers, pulleys are force magnifiers.
Peak voltage is 2
period is 40ms
frequency = 1/period = 25Hz
Answer:
2.83m
Explanation:
The information that we have is
Intensity at 2.0 m: 
and 
we need an intensity level of: 
thus, we are looking for the distance 
.
which we can find with the law for intensity and distance:
we solve for :
and we substitute the known values:
at a distance of 2.83m the intensity level is 40dB
It’s definitely b Yk Why um I don’t really know butttt gut instinct
