At a temperature of 280k, the gas in a cylinder has a volume of 20.0 liters.

if the volume of the gas is decreased to 10.0 liters, what must the temperature be for the gas to remain at a constant pressure?

T = 140 K

Explanation:

As we know by ideal gas law

now if pressure of the gas is constant

then we will have

now we have

now from above equation

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
