Answer: P = 40 W
Explanation: Power is defined as the amount of work per unit time or expressed in the formula of P = W /t
Work is the product of force and distance so W = Fd.
So the working equation will be:
P = Fd / t
= 20 N ( 2.0 m) / 1 s
= 40 W
Is the amount of power exerted.
B because the the organism is changing into another chemical form
Answer:
a) 
b) 
c) Generally the most probable speed is 8m/s as it the most posses by particles being the average
Explanation:
From the question we are told that:
Sample size N=15

Generally the equation for Average speed is mathematically given by

Therefore


b)
Generally the equation for RMS speed of the particle is mathematically given by




c
Generally the most probable speed is 8m/s as it the most posses by particles being the average
New moon, because the New Moon (A) because the sun and the moon work together most when it is there on the tides
Answer:
Oscillation whose amplitude reduce with time are called damped oscillation. This happen because of the friction. In oscillation if its amplitude doesn't change with time then they are called Undamped oscillation
