A "8" grams box is pushed with a force of 100 N for 1m whereas opposing force is 10 N. A) Find the net work done on the box. B)
1 answer:
Answer:
A) Wn = 90J
B) W1 = 100J
W2 = 10J
Explanation:
A) The net work done on the box is calculated by using the following formula:
(1)
F1 = 100N
F2 = 10N
d: distance on which the box is moved = 1m
You replace the values of the parameters in the equation (1):
The net work on the box is 90J
B) The total work done by each force is:
The first box does a work of 100J and the second force does a force of 10J

The frequency of a photon with an energy of 4.56 x 10⁻¹⁹ J is 6.88×10¹⁴ s⁻¹.
<h3>What is a frequency?</h3>The number of waves that travel through a particular point in a given length of time is described by frequency. So, if a wave takes half a second to pass, the frequency is 2 per second.
Given that the energy of the photon is 4.56 x 10⁻¹⁹ J. Therefore, the frequency of the photon can be written as,
Hence, the frequency of a photon with an energy of 4.56 x 10⁻¹⁹ J is 6.88×10¹⁴ s⁻¹.
