To solve this we assume that the gas inside the balloon is an ideal gas. Then, we can use the ideal gas equation which is expressed as PV = nRT. At a constant pressure and number of moles of the gas the ratio T/V is equal to some constant. At another set of condition of temperature, the constant is still the same. Calculations are as follows:

T1 / V1 = T2 / V2

V2 = T2 x V1 / T1

V2 = 2 x 20.0/ 1

<span>V2 = 40 L </span>

in this problem assume that the batteries have zero internal resistance. The currents are flowing in the direction indicated by
Leya [2.2K]

Answer:

1.2 Amps

Explanation:

<em>The question is incomplete, however, according to Ohm's law the current through a conductor between two points is directly proportional to the voltage across the two points.</em>

Given Data

Voltage= 4.4V

Resistance= 5.2 Ohms

V=IR---------------Ohms law

I= V/R

I= 5.2/4.4

I= 1.18

I= 1.2 Amps

Hence the current is 1.2 Amps

Luden [163]

Answer:

P = 22 watts

Explanation:

Given that,

The output power of the generator = 2 a

The output potential difference = 11 V

We need to find the output power of the generator. The formula for the output power is given by :

P=V\times I\\\\P=11\times 2\\\\P=22\ W

So, the output power of the generator is equal to 22 Watts.
