Answer:
Distance covered by Anthony is 3 km. Don't know about displacement though.
Answer:
If force is applied to cause the motion of the body
Explanation:
In the setup given in this diagram, potential energy can be converted into kinetic energy by applying force on the cart or object to move it down the slope.
Potential energy is the energy due to the position of a body. The body has huge potential energy at its current position.
Kinetic energy is the energy due to the motion of a body.
As the body moves down the slope and its velocity increases, it gains massive kinetic energy.
Down the slope, the kinetic energy increases as the potential energy decreases.
At the bottom of the slope, the potential energy becomes zero and the kinetic energy is at its maximum.
Answer:
It will produce a stronger magnetic field.
Explanation:
Ampere’s law states the magnetic field of a solenoid is directly proportional to the current supplied.
The weight of the cooler is (mg). That's (26)(9.8) = 254.8 Newtons.
Its gravitational potential energy while it's up in the top row is (mgh). That's (254.8)(17.5) = 4,459 Joules.
That's how much work it took to get the cooler up to the top row, and that's the energy it gives up when it moves back down to the bench.
In order to bring it down . . .
-- Gravity does 4,459 joules of work on the cooler.
-- The team assistant does NEGATIVE 4,459 joules of work on it.
