Answer:
New volume (V2) = 60 liter
Explanation:
Given:
Amount of helium (V1) = 20 Liter
Temperature (T1) = 100°K
Temperature (T2) = 300°K
Find:
New volume (V2)
Computation:
According to Gas Law:
V1 / T1 = V2 / T2
20 / 100°K = V2 / 300°K
V2 = 60 liter
New volume (V2) = 60 liter

Explanation:
Answer:
While a body is said to be in motion if it changes its position with respect to immediate surroundings.
A body is said to be in uniform motion if it covers equal distances in equal interval of time.
A body is said to be in non-uniform motion if it covers unequal distances in equal interval of time or vice-versa
For an ideal transformer power loss is assumed to be zero
i.e. the power in primary coil due to input voltage must be equal to power in secondary coil due to output voltage
this can be written in form of equation
![V_1 i_1 = V_2 i_2](https://tex.z-dn.net/?f=V_1%20i_1%20%3D%20V_2%20i_2)
here we know that
![V_2 = 140 volts](https://tex.z-dn.net/?f=V_2%20%3D%20140%20volts)
![i_2 = 3.5 A](https://tex.z-dn.net/?f=i_2%20%3D%203.5%20A)
![i_1 = 10 A{/tex]now we will use above equation[tex]140*3.5 = 10 * V_1](https://tex.z-dn.net/?f=i_1%20%3D%2010%20A%7B%2Ftex%5D%3C%2Fp%3E%3Cp%3Enow%20we%20will%20use%20above%20equation%3C%2Fp%3E%3Cp%3E%5Btex%5D140%2A3.5%20%3D%2010%20%2A%20V_1)
![V_1 = 49 volts](https://tex.z-dn.net/?f=V_1%20%3D%2049%20volts)
So primary coil voltage is 49 Volts
