Answer:
Explanation: represends a=v
The answer is
-Small f and large D.
The explanation:
-when The car jack is an example of a machine, which is defined as anything that a person can use to make the exertion of force easier.
-So with the small force he exerts on the jack, the distance that the car is lifted up increases
.
and People needs help of machines to increase their force. People cannot lift a car without a machine. Using the leverage or hydraulic principles the machines increase your force.
If you use a large leverage you execute a large movement with little force and as result the other side will move small distances with a greater force.
<h3><u>Answer;</u></h3>
a) 5.00 x 10^8 J
<h3><u>Explanation;</u></h3>
The work done to move the sailboat is calculated through the equation;
W = F x d
where F is force and d is the distance.
Substituting the known values from the given above,
W = (5.00 x 10⁴ N)(10 km)(1000 m/ 1km)
= 5.00 x 10⁸ J
Thus, the work done is <u>5.00 x 10⁸Joules</u>
Answer:
The total energy stays the same but is converted from being stored as gravitational potential energy into kinetic energy of the car as it moves.
Explanation:
the law of conservation of energy states that the total energy of an isolated system remains constant, and since it is gaining speed that energy will be kinetic
Force is transferred from the moving ball to the stationary ball.
