Please help. If the mass of proton is 1.67X10^-27kg
and the mass of an electron is 9.11 X10^-31kg
Calculate the force of gravitation between
i a protron and on electron
ii two electrons
III two protons
cake G= = 6.67 x 10^11 Nm^-2
distance between the protrons = 4.0m, distance
between the electrons = 2x 10^-2m,
distance between the electrons 2x 10^-2m,
distance between the proton and the
electron =
5.4 x 10^-11m

Which device uses ac current to operate?

A3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular? a 3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular?

If an astronaut takes an object to the moon the following is true (choose only one). a the mass will change but the weight will be the same. b both the mass and the weight of the object will be the same. c the weight will change but the mass will be the same. d both the mass and the weight of the object will change.
