Question:-
A man of 60kg gains 1000 Cal of heat by eating 5 mangoes. His efficiency is 56%. To what weight he can jump by using this energy?
Answer:
4m
Explanation:
Given :
- Mass of the man before eating mangos = 60kg
- After eating five mangoes he gain = 1000Cal = 1000*4.2 = 4200 [1cal = 4.186]
- Efficiency = 56 % = 0.56
To Find :
- Height he can jump
Solution :
Q = mgh,
where m is the mass in kilograms,
g is the acceleration due to gravity (9.8 on Earth),
and h is the height above the ground in meters.
and Q is the sum of all heat transfer into and out of the system.
Therefore,the height to which it reach is 4m

Answer:
Heya sathvika ♥️
Explanation:
✏️After eating 5 mangoes energy gain =1000Cal
Efficiency =5.6%
Energy can be utilized =Efficiency × 5
=560Cal
=2352J
Now, mgh=2352
h=60×9.82352=4m
✒️Hope it works ♥️☺️✌️...
