Verify the statement that gravitational forces between two charges can be neglected compared to the electrostatic forces using the example of two electrons separated by a distance of 1m. Compare the magnitude of the Coulomb’s force and the gravitational force on each electron. Use: Mass of an electron is 9.1×10^−31 kg.
Gravitational constant G=6.67×10^−11 Nm^2/kg^2.
Coulomb's constant k=9×10^9 Nm^2/C^2.
Charge of an electron is −1.6×10^−19 C.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.

statement #3 on andre"s list is false.

because if the tool that you are using is not balanced it there would be false mass.

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
