The net force acting on the box of mass 1.75kg when it is pushed across a ground with coefficient of friction k=0.267 with a force of 8.35N, is 3.77N.
To find the answer, we have to know more about the basic forces acting on a body.
<h3>How to find the net force on the box?</h3>
- Let us draw the free body diagram of the given box with the data's given in the question.
- From the diagram, we get,
where, N is the normal reaction, mg is the weight of the box, 
is the net force, f is the kinetic friction.
- We have the expression for kinetic friction as,
- Thus, the net force will be,
Thus, we can conclude that, the net force acting on the box of mass 1.75kg when it is pushed across a ground with coefficient of friction k=0.267 with a force of 8.35N, is 3.77N.

Answer:
A. It uses less energy to make something from recycled materials than from new materials.
Explanation:
I think it is this one because it is the only one that is not harmful to the environment. Also, I took the test a few minutes ago.
To solve the problem it is necessary to take into account the concepts related to frequency depending on the wavelength and the speed of light.
By definition we know that the frequency is equivalent to,
where,
c= Speed of light
While the wavelength is equal to,
Where,
L = Length
n = Number of antinodes/nodes
PART A) For the first part we have that our wavelength is 110MHz, therefore
Therefore the distance between the nodal planes is 1.36m
PART B) For this part we need to find the Length through the number of nodes (8) and the wavelength, that is,
Therefore the length of the cavity is 10.90m
Answer:
<h3>F=2,111.9</h3>
F= two thousand one hundred eleven point nine
Explanation:
Force equals <em><u>Mass(kg)</u></em> times acceleration (M/s^2)
F=<em><u>m</u></em>a
F= <u><em>215.5</em></u> x 9.8
