Answer:

18301.4Kg

Explanation:

Step 1:

Data obtained from the question. This include the following:

Mass 1 (M1) = 0.512Kg

Mass 2 (M2) =..?

Distance apart (r) = 0.0250m

Force (F) = 0.001N

Gravitational force constant (G) = 6.67x10^-11Nm²/Kg²

Step 2:

Determination of the mass, M2 needed to create a force of 0.001N.

This can be obtained as follow:

F = GM1M2/r²

0.001 = 6.67x10^-11 x 0.512 xM2/0.025²

Cross multiply

6.67x10^-11 x 0.512 xM2 = 0.001x0.025²

Divide both side by 6.67x10^-11 x 0.512

M2 = (0.001x0.025²)/(6.67x10^-11x0.512)

M2 = 18301.4Kg

Therefore, a mass of 18301.4Kg is needed

How many coulombs of charge do 50 * 10^31 electrons possess

Angelina_Jolie [31]

Quantity of Charge , Q = ne
Where n = number of electrons
e = charge on one electron = -1.6 * 10 ^-19 C.
n = 50 * 10^31 electrons

Q = (50 * 10^31)*( -1.6 * 10 ^-19 ) = -8 * 10^13 C.

Note that the minus sign indicates that the charge is a negative charge.

Which object would have the most momentum?

soldier1979 [14.2K]

Answer:

Explanation:

Momentum is the product or multiplication of a body's mass and its speed.

Since all options have the mass and speed in the same units, there is no need for conversion.

A. 20 x 500 = 10000, B. 200 x 60 = 12000

The same goes for the rest!
