Given:
Amount of heat produced = 100 kcal per hour
Let's find the rate of energy production in joules.
We know that:
1 calorie = 4.184 Joules
1 kcal = 4.184 Joules
To find the rate of energy production in Joules, we have:

Therefore, the rate of energy production in joules is 418.4 kJ/h which is equivalent to 418400 Joules
ANSWER:
418.4 kJ/h
The answer will be B) Meter
Answer:
Charge quantization is the principle that the charge of any object is an integer multiple of the elementary charge
Answer: The rate of energy transfer by a 5 ohms resistor when there is a current of 0.2 A in it.= 1.25 watt.
Explanation:
- The rate of energy transfer from one point to another is known as power.
- Its SI. unit is <em>Watt.</em>
Formula to compute power:
Power =
, I = cureent, R = resistance.
Given R = 5 ohm , Current = 0.5 A.
Then, power = 
Hence, the rate of energy transfer by a 5 ohms resistor when there is a current of 0.2 A in it.= 1.25 watt.
