If the motorcycle can go from 0 to 50mph in 3 seconds the person is describing the motorcycle's acceleration.
To make sure the answer is correct
Answer:
T=157.06 N
Explanation:
Given that
Mass of first block = 21.1 kg
Mass of second block = 12.9 kg
First mass is heavier than first that is why mass second first will go downward and mass second will go upward.
Given that pulley and string is mass less that is why both mass will have same acceleration.So lets take their acceleration is 'a'.
So now from force equation
21.1 x 9.81 - 12.9 x 9.81 =(21.1+12.9) a
Lets tension in string is T
T=21.1(9.81-2.36) N
T=157.06 N
Dalton Was the first one to attempt a publishing list of relative atomic masses.
This system is used in hydraullics to increase the force on larger area
This is based upon the principle of Pascal's law
As per Pascal's law the pressure will remain the same on the same level
so if we applied some small amount of force on small area then the pressure will transmitted into the liquid by same amount
here a= smaller area
F = applied smaller force
Now the pressure will transmit to bigger area without any change
so the force that is received by bigger area will be
A = area of the bigger platform
so by the above expression we can say that overall force will be more on bigger area.
So above statement is TRUE
