Explanation:
Below is an attachment containing the solution.
Answer:
B. Pascal's principle.
Explanation:
Pascal's law
It states that when a pressure is applied to an enclosed fluid then this pressure transfer is every direction with same magnitude.The fluid should be in compressible.
This law mostly used in the high weight lifting machine like when we want to lift our car from one ground floor to the top floor .This is done by the help of hydraulic ram system.
So the answer is B.
B. Pascal's principle.
Answer:
P.E = mgh
K.E = 1/2mv²
Explanation:
P.E = mgh
That is m= mass in kilograms, g=acceleration due to gravity and h= height in meters.
K.E = 1/2mv²
That is 1/2 of an object's mass multiplied by the velocity squared.
1. you need to increase their speeds
2. you need to decrease their speeds
