Answer:
All color wavelengths are being absorbed
Explanation:
There is no color reflected when the color is black
Using Fnet= ma, constant motion means 0 acceleration, Fnet ( force ) will be also 0
Answer:
The gravitational potential energy, P.E = 3345484.8 J
Explanation:
Given,
The mass of the person, m = 64 kg
The elevation of the village, h = 5334 m
The gravitational potential energy is the energy possessed by the body due to its height from the surface of the Earth at sea level.
Therefore, the gravitational P.E at height h above sea level is given by the relation
<em>P.E = mgh joules</em>
Substituting the given values,
P.E = 64 kg x 9.8 m/s² x 5334 m
= 3345484.8 J
Hence, the gravitational potential energy associated with the person, P.E = 3345484.8 J
I know most of the answers will say infinity, but still this needs deeper look about its physical meaning and does it consider a practical logic?
Infinity usually used for something we could not measure, however the reality may be different!
Answer:
Acceleration is the rate of change in the velocity of object per unit time.
Explanation:
Acceleration :- A measure of the change in the velocity of an object per unit time. It is vector quantity.
If the velocity of object changes from initial value u to find value v in the time t, then acceleration a is
