When a potential V is applied across a capacitor, a charge q is stored. What charge is stored if the potential across the capaci
Readme [11.4K]

Answer:

q' = 0.5q

Hence, the charge stored is also halved

Explanation:

The capacitance of a capacitor is given by the following formula:

C = \frac{q}{V} ------- eqn(1)

where,

C = Capacitance of the capacitor

q = charge stored in the capacitor

V = potential across the capacitor

Now, if we make potential half of its initial value:

C = \frac{q'}{0.5V}\\\\CV = 2q'\\using\ eqn(1):\\\frac{q}{V}(V) = 2q'\\\\<u></u>

<u>q' = 0.5q </u>

<u>Hence, the charge stored is also halved </u>

What happens when pressure is applied to a solid.​
weeeeeb [17]

Answer:

When the pressure surrounding a substance increases, the freezing point and other special points also go up. It is easier to keep things solid when they are under greater pressure. Generally, solids are more dense than liquids because their molecules are closer together.

What is the effect on the gas’ pressure when compressing a gas to 1/3 of its volume? Explain
denis23 [38]

Explanation:

It's pressure become three times larger because according to Boyles Law the pressure of fixed mass of gas is inversely proportional to it's volume provided that temp remains constant. That means a reduction in volume, will result in an increase in pressure and vice versa.
