Choice-'b' says the formula for kinetic energy in words.
KE = (1/2) · (M) · (S²)
Answer:
Evolutionary
Explanation:
Because our ancestors were afraid of these poisonous spiders and snakes which lead to them to telling their kids of these dangers. Their kids will fear them without even encountering any and this will also be passed on to their future generations.

Answer:
Power generated = 1,000W
Explanation:
Given
Mass, m= 60kg
Distance, d = 10m
Time, t = 6s
To calculate Power, First we need to get the total work done
Work done is calculated by multiplying force by distance;
Taking acceleration due to gravity as
Force = mg
Force = 60 * 10
Force = 600N
So, Work = Force * Distance
Work = 600N * 10m
Work = 6000Nm or 6000J
Power is calculated by
By Substitution
Power =
Power = 1000W
