A ten year old boy is 125 cm tall. If the present height of the boy is 78 % of his full height , Calculate the full height which the boy is eventually reached at the end of te growth period.
Answers
Answer :
Given
Present height of boy = 125 cm
Percentage of full height = 78
So
Full height of boy = Present height of the boy / percentage of full height
= 125/78*100 cm
= 1.6025*100 cm
= 160.25 cm
Thus full height of boy will be 160.25 cm
Also Remember
The height of a child is depended on the genes inherited form the parents. For example , if both or one of the parents are very tall like 6 feet then the son and daughter is likely to grow 5 feet 11 inches or full 6 inches.The height of person is more or less similar is that of some family members.
Answer:
When an object is dropped from a height, its gravitational potential energy is converted to kinetic energy as it falls.
The loss in potential energy will be equal to the gain in kinetic energy.
We can simply calculate the gravitational potential energy lost using the formula Ep=m⋅g⋅h:
⇒Ep=((20)⋅(9.81)⋅(10)) J
=1962 J
