Answer;

-A triple beam balance

Explanation;

-Mass is the amount of matter in an object. Move to a different planet and an object's weight will change, but its mass will be the same. There are a couple of ways to measure mass. The Mass of an object doesn't change when an object's location changes. Weight, on the other hand does change with location.

-Mass is measured by using a balance comparing a known amount of matter to an unknown amount of matter. Weight is measured on a scale.

Stolb23 [73]

Answer:

(A) 421 J energy stored in the capacitor for one flash.

(B) The value of capacitance is 0.0537 F

Explanation:

Given :

(A)

Time t = \frac{1}{675}

Average power P = 2.7 \times 10^{5} W

From power equation,

   P= \frac{E}{t}

So energy in one light is given by,

   E = Pt

  E = 2.7 \times 10^{5} \times \frac{1}{675}  = 400 J

Since efficiency is 95 % so we can write, energy stored in one flash,

E_{tot} = \frac{400}{0.95} = 421 J

(B)

From the formula of energy stored in capacitor,

 E = \frac{1}{2}C V^{2}

Where E = E_{tot} and V = 125 V

 C = \frac{2E}{V^{2} }

 C = \frac{2 \times 421}{15625}

 C = 0.0537 F
