Answer:

0.017 s

Explanation:

The period of a periodic signal is defined as the reciprocal of the frequency:

$T=\frac{1}{f}$

where

T is the period

f is the frequency

For the electrical power, the frequency is

f = 60.0 Hz

Substituting into the previous equation, we find the period:

$T=\frac{1}{60.0 Hz}=0.017 s$

Answer: Hence, the final temperature is 350 K

Explanation :

To calculate the final temperature of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

$\frac{P_1}{T_1}=\frac{P_2}{T_2}$

where,

$P_1\text{ and }T_1$ are the initial pressure and temperature of the gas.

$P_2\text{ and }T_2$ are the final pressure and temperature of the gas.

We are given:

$P_1=880mmHg\\T_1=20^0C=(20+273)K=293K\\P_2=1050mmHg\\T_2=?$

Putting values in above equation, we get:

$\frac{880mmHg}{293K}=\frac{1050mmHg}{T_2}\\\\T_2=350K$

Hence, the final temperature is 350 K
