A book is sitting in a table. Jackie is pushing the book with a force of 9 N. If the force of friction is 4 N to the left, what

is the net force

Bumek [7]3 years ago
4 0

Answer:

The net force is 5N

Explanation:

A shown in the diagram,

we let P be the force Jackie applied and

F_r

be the frictional force.

To get the net force, we subtract the frictional force from the applied force.

This implies that,

F_n= P-F_r

F_n= 9 - 4

F_n=5N

Suppose that a charged particle of diameter 1.00 micrometer moves with constant speed in an electric field of magnitude 1.00×105
Dovator [93]
It's a bit of a trick question, had the same one on my homework. You're given an electric field strength (1*10^5 N/C for mine), a drag force (7.25*10^-11 N) and the critical info is that it's moving with constant velocity(the particle is in equilibrium/not accelerating). 
<span>All you need is F=(K*Q1*Q2)/r^2 </span>
<span>Just set F=the drag force and the electric field strength is (K*Q2)/r^2, plugging those values in gives you </span>
<span>(7.25*10^-11 N) = (1*10^5 N/C)*Q1 ---> Q1 = 7.25*10^-16 C </span>

Sveta_85 [38]

Answer:

182.28 W

Explanation:

Here ,

m = 7.30 Kg

distance , d= 28.0 m

time , t = 11.0 s

average power supplied = change in potential energy/time

average power supplied = m×g×d/time

average power supplied = 7.30×9.81×28/11

average power supplied = 182.28 W

the average power supplied is  182.28 W

. How does the area of a rectangle relate to the lengths of each side?
iragen [17]
Area is 2-dimensional which means it has a length and a width area is measured in square units such as square inches, square feet or square meters. To find the area of a rectangle multiply the length by the width.
