Answer:
Number of electrons, n = 12 electron
Explanation:
Given that,
The distance between charged spheres, 
The object experiences an electrostatic force that has a magnitude of, 
The electric force between spheres is given by :
Let there are n number of electrons. Using quantization of electric charge we get :
n = 11.93 electrons
or
n = 12 electrons
Hence, 12 electrons produce the charge on one of the objects.
The average rate of change of distance over the time interval
3 ≤ t ≤ 6 represents the coin's average velocity over that interval.
I think the word would be increases. I don't know what the options are though.
0J
According to the law of conservation of energy, the potential energy is converted to kinetic energy. Remember, potential energy is calculated using height and weight. If the ball is on the ground, height is 0.
Answer: 592.37m
Explanation:
Person D is the blue line.
The total displacement is equal to the difference between the final position and the initial position, if the initial position is (0,0) we have that he first goes down two blocks, then right 6 blocks. then up 4 blocks, then left 1 block.
Now i will considerate that the positive x-axis is to the right and the positive y-axis is upwards.
Then the new position will be, if B is a block:
P =(6*B - 1*B, -2*B + 4*B) = (5*B, 2*B)
And we know that B = 110m
P = (550m, 220m)
Now, then the displacement will be equal to the magnitude of our vector, (because the difference between P and the initial position is equal to P, as the initial position is (0,0)) this is:
P = √(550^2 + 220^2) = 592.37m
