A calorie is a unit of heat or energy and it equals about `4.2 J, where 1 J = 1 kg m^(2) s^(-2)`. Suppose we employ a system of units in which the unit of mass equals `alpha kg`, the unit of length equals is `beta m` , the unit of time is `gamma s`. Show tthat a calorie has a magnitude `4.2 alpha^(-1) beta^(-1) gamma^(2)` in terms of the new units.

To solve the problem, we need to express the value of a calorie in terms of a new system of units defined by \(\alpha\) (mass), \(\beta\) (length), and \(\gamma\) (time).
### Step-by-Step Solution:
1. **Understand the SI Unit of Joules**:
The SI unit of energy (or heat) is the joule (J), which is defined as:
\[
1 \text{ J} = 1 \text{ kg} \cdot \text{m}^2 \cdot \text{s}^{-2}
...
The calorie is a unit of heat or energy and it equals about 4.2 J where 1J=1kgm^(2)s^(-2) . Suppose we employ a system of units in which the unit of mass equals alpha kg, the unit of length equals beta m and the unit of time is gamma s. Show that the calorie has a magnitude of 4.2alpha^(-1) beta^(-2) gamma^(2) in terms of the new units.
If the unit of mass is alpha kg, the unit of length is beta metre and the unit of time is " gamma ' second, The magnitude of calorie in the new system is (1 Cal = 4.23)
A new system of units is proposed in which unit of mass is alpha kg, unit of length beta m and unit of time gamma s. How much will 5 J measure in this new system ?
A new system of units is proposed in which unit of mass is alpha kg, unit of length beta m and unit of time lambda s. How much will 5 J measure in this new system ?
Suppose we employ a system in which in which the unit of mass equals 100 kg , the unit of length equals 1 km and the unit of time 100 s and call the unit of energy eluoj ( joule written in reverse order), then what is the relation between eluoj and joule?
Imagine a system of units in which the unit of mass is 100 kg, length is 1 km and time is 1 minute Then 1 joule in this system is equal to
If the unit of force is 1N, the unit of work done is 10 J and the unit of time is 1 second, the unit of mass is
Name the S.I. unit of heat. How is it related to the unit calorie?
In a certain system of units, 1 unit of time is 5 sec, 1 unit of mass is 20 kg and 1 uint of length is 10m. In this system, one unit of power will correspond to :-
