Question :
If a body acquires a charge of -0.02 C, has it gained or lost electrons? Many?
Solution :
We know, charge gained is shown by negative sign.
Since, charged acquired is given as -0.02 C .
Therefore, it is body has gained electrons.
Now, number of electrons is given by :
Hence, this is the required solution.
Let’s do this together!
Okay so the acceleration formula is vf-vi over time .
So the initial velocity (vi) 7m/s final velocity (vf) is 16m/s so we’re going to subtract 16-7 which is 9
M/s
So the time is 5s so 9m/s divided into 5s is 1.8m/s/2
So the answer is 1.8m\s2

What is (Fnet3)x, the x-component of the net force exerted by these two charges on a third charge q3 = 55.0 nC placed between q1 and q2 at x3 = -1.220 m ? Your answer may be positive or negative, depending on the direction of the force. Express your answer numerically in newtons to three significant figures.
Answer:
The net force exerted on the third charge is
Explanation:
From the question we are told that
The third charge is
The position of the third charge is
The first charge is
The position of the first charge is
The second charge is
The position of the second charge is
The distance between the first and the third charge is
The force exerted on the third charge by the first is
Where k is the coulomb's constant with a value
substituting values
The distance between the second and the third charge is
The force exerted on the third charge by the first is mathematically evaluated as
substituting values
The net force is
substituting values
The speed of the second satellite is less than the speed of the first satellite.
<h3>What is speed?</h3>
The speed of any moving object is the ratio of the distance covered and the time taken to cover that distance.
Given is a satellite is in a circular orbit around a planet. A second satellite is placed in a different circular orbit that is farther away from the same planet.
When the distance from the center of the orbit increases, the time to complete the orbit will be greater.
Thus, the speed of the second satellite is less than the speed of the first satellite.

Muttered is the same thing like mumble.
It's like when you are speaking and no one couldn't hear what you said.
So Muttered is when you say something low .
