Two spherical objects are separated by a distance of 2.59 × 10-3 m. The objects are initially electrically neutral and are very
kodGreya [7K]

Answer:

Number of electrons, n = 12 electron

Explanation:

Given that,

The distance between charged spheres, d=2.59\times 10^{-3}\ m

The object experiences an electrostatic force that has a magnitude of, F=4.94\times 10^{-21}\ N

The electric force between spheres is given by :

F=\dfrac{kq^2}{d^2}

q=\sqrt{\dfrac{Fd^2}{k}}

q=\sqrt{\dfrac{4.94\times 10^{-21}\times (2.59\times 10^{-3})^2}{9\times 10^9}}

q=1.91\times 10^{-18}\ C

Let there are n number of electrons. Using quantization of electric charge we get :

q=ne

n=\dfrac{q}{e}

n=\dfrac{1.91\times 10^{-18}}{1.6\times 10^{-19}}

n = 11.93 electrons

or

n = 12 electrons

Hence, 12 electrons produce the charge on one of the objects.

11. A bowling ball has a mass of 7 kg and a velocity of 3 m/s.<br> (A) What is the ball's momentum?
DaniilM [7]

Answer: 21 kg x m/s

Momentum can be found using the equation p = mv, or momentum = mass times velocity.

Therefore, to find the momentum of the bowling bowl, you can plug the mass and velocity values into the equation to get p = (7kg)(3m/s)

Solve the equation to get a momentum of 21kg x m/s

I hope I could help :)

Two hockey players , big Jim and little Tim collide head on and get tangled while going for the puck 65kg time was traveling at
12345 [234]
I will assume that big Joe is big Jim. The equation for the momentum is p=m*v, where m is the mass of the body and v is the velocity. Big Joe has a mass m=105 kg and speed v=5.2 m/s. When we input the numbers:

p=105*5.2=546 kg*(m/s).

So big Joe's momentum before the collision is p=546 kg*(m/s).
