Suppose two point charges, Q1 = +3.37 x 10-6 C and Q2 = -8.21 x 10-6 C, are separated by a distance d = 1.99 m. Using Coulomb's Law, find the attractive force between the charges. A) F = 0.0626 N B) F = 0.0313 N C) F = -0.0626 N D) F = -0.0313 N
Ps If you could explain how you got it it would help a lot. Thank you so much.

Amanometer is used to measure the air pressure in a tank. the fluid used has a specific gravity of 1.25, and the differential height between the two arms of the manometer is 34 in. if the local atmospheric pressure is 12.7 psia, determine the absolute pressure in the tank for the cases of the

Acrow drops a 0.11kg clam onto a rocky beach from a height of 9.8m. what is the kinetic energy of the clam when it is 5.0m above the ground? what is its speed at that point?

An astronaut in space cannot use a scale or balance to weigh objects because there is no gravity. but she does have devices to measure distance and time accurately. she knows her own mass is 77.4 kg , but she is unsure of the mass of a large gas canister in the airless rocket. when this canister is approaching her at 3.50 m/s , she pushes against it, which slows it down to 1.30 m/s (but does not reverse it) and gives her a speed of 2.60 m/s . what is the mass of the canister?
