Answer:
Explanation:
given,
Speed of car = v
new speed of car v'= 1.8 v
Kinetic energy of the car
new Kinetic energy of energy
hence, the kinetic energy is increased by the factor of 3.24.
Answer:
Explanation:
Calorie is a common term used to describe the amount of energy that can be derived from food products.
We quantify foods based on the calories of energy they possess. A high calorific food will yield more energy to the body and is often desired for intense physical activities.
Calorie is defined as the amount of heat energy needed to raise the temperature of 1g of a substance by 1°C.
Food calories slightly differs in definition and they imply the amount of heat needed to raise the temperature of 1kg of water by 1°C.
