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.

Average velocity is calculated as the division of displacement and change in time so the answer would be 804 km/36000 s=0.02 m/s
Explanation:
It is given that,
The distance from the pitcher's mound to the batter is 43 feet, d = 43 feet = 0.00814 miles
Speed with which ball leaves the ball, v = 110 mph
Let t is the time elapses between the hit and the ball reaching the pitcher. It is given by :
t = 0.000074 hours
or
t = 0.2664 seconds
So, the time between the hit and the ball reaching the pitcher is 0.2664 seconds. Hence, this is the required solution.
An incandescent bulb produces light that comes from the heating of a filament. A compact fluorescent bulb produces light when a substance is hit by electromagnetic radiation. Compact fluorescent bulbs are more efficient than incandescent bulbs.
The first law of thermodynamics is a version of the law of conservation of energy, adapted for thermodynamic processes. Therefore, a system with lower heat emissions would be more efficient.
The second law of thermodynamics states that the total entropy of an isolated system (the thermal energy per unit temperature that is unavailable for doing useful work) can never decrease. In our context, it means that the system with the least amount of losses would be more efficient. As a conclusion the fluorescent bulb would be more efficient.
