Batteries convert chemical energy into electrical energy. It is able to store electrical energy in the form of chemical energy.
Have you ever seen the two different sides of a battery? One side is often labelled with a positive sign, and the other with a negative sign. Inside the battery are four cells where two processes take place. One process uses electrons, and the other creates electrons. When the electrons flow, it creates electricity.
Drums convert mechanical energy into sound energy.
When a musician bangs his/her drumstick on the drum, the motion makes a sound. This movement turned motion into sound.

Answer

Total force exerted by brake cylinders is 249.69 N

Explanation:

We have given that force $F_1=38.7N$

And area of the cylinders $A_1=7.61cm^2=7.61\times 10^{-4}m^2$

We have to find the total force

We have given total surface area $A_2=49.1cm^2=49.1\times 10^{4}m^2$

From pascal's law we know that $P_1=P_2$

And we know that $P=\frac{F}{A}$

So $\frac{F_1}{A_1}=\frac{F_2}{A_2}$

$\frac{38.7}{7.61\times 10^{-4}}=\frac{F_2}{49.1\times 10^{-4}}$

$F_2=249.69N$
