The force of gravity on you is greatest when you are standing _____.a. far above Earth's surface
b. just above Earth's surface
c. on Earth's surface
Answers
The acceleration of gravity at the surface of the Earth is approximately 9.8 meters (32 feet) per second per second. As a result, during free fall, an object's speed rises by around 9.8 meters per second.
Explain about the force of gravity?
The force that binds all masses in the universe together, particularly the pull of the earth's mass on objects that are close to its surface.
The term gravitational force refers to the force that the earth exerts on a body. Examples of motion caused by gravitational force include the downward motion of water in a river, the downward motion of water in a stream, and the upward motion of a ball when it is thrown.
All physical things with mass are drawn to the gravitational force, which can be thought of as an attracting force. It is the known natural force that is by far the weakest. representation in mathematics. The formula for gravitational force is F = G m 1 m 2 r in mathematics.
The answer is on earth surface

If you're asked to find a displacement, then the first thing the asker has to do
is define the part of the graph that he's interested in.The easiest way to do that
is to specify the start-time and end-time. Once you have those, the displacement
is easy. Just look at the graph. Find the position at the end, and the position
at the beginning. Subtract the beginning position from the ending position, and
that's the displacement.
Ignore everything in between. No matter how many curves, curls, breaks, or
stops the graph may have on the way, you don't care. The displacement is just
the difference between the end position and the start position.

1). A driver presses the gas and the car speeds up.
2). A driver presses the brake and the car slows down.
3). A driver turns the steering wheel slightly. The car's speed doesn't change
as it goes around the curve.
4). A stone is tossed into the air. Gravity accelerates it from the moment it
leaves the thrower's hand until it hits the ground.
5). A new TV satellite is successfully launched and placed in a perfect circular
orbit around the Earth. The satellite's motion is accelerated forever, 24/7/365 .
"Acceleration" means any change in the speed or direction of motion. Any
object that's not moving at constant speed in a straight line is accelerated.

Answer:
which corresponds to the second option shown: "voltage times amperage"
Explanation:
The electric power is the work done to move a charge Q across a given difference of potential V per unit of time.
Since such electrical work is the product of the potential difference V times the charge that moves through that potential, and this work is to be calculated by the unit of time, we need to divide the product by time (t) which leads to the following final simple equation:
Notice that we replaced the quotient representing charge per unit of time (Q/t) by the actual current running through the circuit.
This corresponds to the second option shown in the question: "Voltage times amperage".
Answer:
The product of voltage times amperage
