Answer:
Hydraulic pressure is the pressure of hydraulic fluid which it exerts in all direction of vessel,hose or anything in which it is supposed to exert the force per unit area. This pressure is responsible to create a flow in a hydraulic system as fluid flows from high pressure to low pressure . Thus energy is transferred in a hydraulic system through a fluid medium.

Explained below
Explanation:
To explain this, let's consider a tennis ball being launched from the top of a very high building.
Now, if the tennis ball is launched horizontally without any upward angle but with an initial velocity of 10 m/s. In this motion, If there is no gravity, the tennis ball would continue in motion at that same speed of 10 m/s in the horizontal direction. However, in reality, gravity causes the tennis ball to accelerate downwards at a rate of 9.8 m/s for every second. This implies that the vertical velocity component is changing at the rate of 9.8 m/s every second.
Thus, after 1 second, horizontal velocity component will remain 10 m/s and vertical component will be 9.8 m/s × 1 = 9.8 m/s downwards.
Also, after 2 seconds, the vertical velocity component will remain 10 m/s, however the vertical component will now be 9.8 × 2 = 19.6 m/s downwards.
Same procedure is repeated as t increases by 1 second.
Answer:
Explanation:
Given
Tom is on half way between the center and the outer rim
Mary is on the extreme outer rim
Suppose 
is the angular velocity of ride with radius of outer rim be R
angular acceleration of Ride
At any instant both Tom and Mary experience the same angular speed
(b)Linear velocity at any instant
Thus Tom has higher linear speed
(c) For radial Acceleration
Tom has higher radial Acceleration as it is directly Proportional of radius
