Answer:

Explanation:

We can use the Einsten's relation which states the equivalence between mass and energy:

where

E is the energy

m is the rest mass of the object

c is the speed of light

By using this formula and m=2.5 kg, we can find the equivalent energy of the object:

Draw the free body diagram for the mass W2.

In it the only forces that appear are W2 (downward) and the Tension of the cable A (upward), TA

Net force = 0 => W2 = TA

Then TA = 200 N

A 15-µF capacitor and a 25-µF capacitor are connected in parallel, and charged to a potential difference of 60 V. How much energ
Alborosie

Answer:

Energy stored, E = 0.072 J

Explanation:

Given that,

Capacitance, C_1=15\ \mu F

Capacitance, C_2=25\ \mu F

These two capacitor are connected in parallel, and charged to a potential difference of, V = 60 volts

We know that in parallel combination of capacitor, the equivalent capacitance is given by :

C=C_1+C_2\\\\C=(15+25)\ \mu F\\\\C=40\times 10^{-6}\ F

The energy stored in the capacitor is given by :

E=\dfrac{1}{2}CV^2\\\\E=\dfrac{1}{2}\times 40\times 10^{-6}\times (60)^2\\\\E=0.072\ J

So, the energy stored in the capacitor in this capacitor combination is 0.072 J.
