The force of repulsion between two identical positive charges is 0.800 N when the charges are 0.100 m apart. Find the value of each charge.

Answers

Answer:

Value of each charge is given as

q = 9.43 * 10^(-7) C

Explanation:

As we know that electrostatic force between two charges is given as

F = (kq_1 q_2)/(r^2)

here we know that

q_1 = q_2 = q

F = 0.800 N

r = 0.100 m

now we have

F = ((9* 10^9) q^2)/((0.100)^2)

0.800 = 9* 10^(11) q^2

q = 9.43 * 10^(-7) C

Emily jogs 3 laps at the track to warm up. She jogs at 5 mph. Then she runs 3more laps at 7 mph. What is true about her average speed and her average
velocity?

Answers

Answer:

Emily's average speed is 6 mph and her average velocity is zero.

Explanation:

We can calculate the average speed as:

s = (s₁ + s₂) / 2 = (5 mph + 7 mph ) /2 = 12 mph / 2 = 6 mph

s: average speed

s₁: speed in the first 3 laps

s₂: speed in the second 3 laps

And we can calculate the average velocity as:

v = (df - di) / t = (0 m - 0 m) / t = 0 m / t = 0 m / s

v: average velocity

df: final displacement

di: initial displacement

t: time

As Emily is finally in the same place, it doesn't matter the time to finish the 6 laps, we know that the displacement is zero so the average velocity is zero too.

How can you conclude about how forces add?

Answers

The amount of forces is called a newton, and the way you add newtons is looking at which force is being pushed of pulled at more newtons and subtract it at the other push or pulls and you get the way its going with how much force is being applied to it

(Sorry my answer has no English xD)
forces add by making it to pull a object easier
