The sources of error that could account for any differences between calculated values and the accepted values are approximation of values during calculation and Incorrect reading of temperature changes.
The given parameters:
- Specific heat of water = 4186 J/kg
<h3>What is specific heat capacity?</h3>
- This is quantity of heat required to raise the temperature of 1 kg of the substance by 1 kelvin.
The source of error that could account for any differences between calculated values and the accepted values include;
- Approximation of values during calculation.
- Incorrect reading of temperature changes.

The average velocity of an object is given by:
Average velocity = total displacement / total time
First, we calculate the time taken to reach the maximum height of the ball. This occurs when the final velocity is 0.
Vf = Vi + at
0 = 19.6 - 9.81 * t
t = 2 seconds
The total trip will be of 4 seconds (2 seconds up, 2 seconds down)
The total displacement is given by:
s = ut + 1/2 * at²
s = 19.6 * 2 - 0.5 * 9.81 * 2²
s = 19.6 meters
This is the distance maximum height, so the total height is
19.6 * 2 = 39.2 meters
Average velocity = 39.2 / 4
Average velocity = 9.8 m/s
<span>A. A girl hits a volleyball. Her hand exerts a force on the ball, and the ball exerts a force on her han</span>
Magnitude of acceleration
Explanation:
We know that acceleration can increase depending in the force applied on an object, any object with a greater mass will apply a greater force. F = M(a).
