This question involves the concepts of the specific heat, mass, and, temperature.
The average Cp value is "".
<h3>SPECIFIC HEAT VALUE</h3>The specific heat of a gas at constant pressure is given by the following formula:
where,
- Cp = specific heat = ?
- ΔQ = heat required = 522 KJ
- ΔT = change in temperature = 800 K - 300 K = 500 K
- m = mass of gas = 1 kg (taking unit mass)
Therefore,

George's speed per second is 76.92 m/s
George's velocity in meters per second was 38.46 m/s (North)
<u>Explanation:</u>
When dividing the total distance covered by object by time, we get the value for average speed.
<u>Given:</u>
t = 13 seconds
Calculate the distance without consideration of motion’s direction. So, the distance walks 750 m north first, and then turn around walks 250 m south, so the total distance covered is
d = 750 + 250 = 1000 meters
To find the rate per second, simply divide the distance by the time.
In given case, the students walks 750 m north first, and then turn around walk 250 m south. The displacement is the distance in a straight line between the initial and final position: therefore, in this case, the displacement is
d = 750 (north) - 250 (south) = 500 m (north)
The time taken is t = 13 s
So, the average velocity is (North)
And the direction is north (the same as the displacement).
