Answer:
The force is 
Explanation:
From the question we are told that
The first diameter is 
The second diameter is 
Generally the first area is

=> 
=> 
The second area is



For a hydraulic press the pressure at both end must be equal .
Generally pressure is mathematically represented as

=>

=> 
=> 
The height above the ground from where the skier start is 11.5 m.
<h3>
Conservation of energy</h3>
The height above the ground from where the skier start is determined by applying the principle of conservation of energy as shown below;
P.E = K.E
mgh = ¹/₂mv²
gh = ¹/₂v²

Thus, the height above the ground from where the skier start is 11.5 m.

Explanation:
Because they change the direction of force and multiply the effort.
They increase the rate of doing work.
So, MA of first class lever can be one or greater than one or less than one
The strength of the thrust is 122 newtons.
The motion of the rocket is described by the second Newton's law, whose model is shown below:
(1)
Where:
- Thrust, in newtons
- Drag, in newtons
- Mass of the rocket, in kilograms
- Net acceleration of the rocket, in meters per square second
If we know that
,
and
, then the strength of the thrust is:



The strength of the thrust is 122 newtons.

<span>In physics, the law of conservation of energy states that the total energy of an isolated system remains constant—it is said to be conserved over time. Energy can neither be created nor destroyed; rather, it transforms from one form to another. For instance, chemical energy can be converted to kinetic energy in the explosion of a stick of dynamite.</span>
