The amount of energy required to raise the temperature of one gram of water by one celsius degree is called a calorie.
<h3>How can you define calorie?</h3>
In physics, we can define it as a unit of measurement that defines the amount of energy to raise the temperature of 1 gram of water by 1°C. Each material has its unique calorie, however by definition we use water as it is the lowest of all the elements.
Normally, calorimetry is directly linked with the thermal capacity that an element has to contain heat.

Answer:
mass-to-light ratio is the ratio of the mass of a body and the light output it has. it is represented by in terms of a single number and and tells us about the kind of stars making up the most luminous population in a galaxy. the mass-to-ratio of stars is greater than 1, for dark matter is 100 times high and very low for dust. higher mass-to-ratio mean that in a galaxy on average every solar mass emits a light less than the sun of the earth solar system does.
the large mass-to-light ratio shows that gas and dust is being analyzed.
Answer:
For the car to move with constant velocity the additional force required is
Explanation:
From the question we are told that
The net force of the car is
Generally the total force acting on the car is the net force plus the force due to gravity acting in direction of the car (Let denote it as )
So the total force acting on the car is mathematically represented as
Here this F representing the total force can be mathematically represented as
Now for constant velocity to be attained, the acceleration of the car will be zero
So at constant velocity
=>
So
=>
=>
