Answer:
Anita 's power rating during this portion of the climb is 1568 Watts.
Explanation:
Given that,
Mass of the body, m = 800 kg
Height, h = 20 m
Time, t = 100 s
We need to find the Anita 's power rating during this portion of the climb. Power rating of an object is given by the work done per unit time. It is given by :
P = 1568 Watts
So, Anita 's power rating during this portion of the climb is 1568 Watts. Hence, this is the required solution.
The energy carried by a single photon is given by
where h is the Planck's constant and f is the frequency of the photon.
The photon of our exercise has a frequency of
, therefore its energy is
where h is the Planck's constant and f is the frequency of the photon.
The photon of our exercise has a frequency of
