There are four accepted fundamental forces or interactions undefined by scientists: gravitational, electromagnetic, strong nuclear,
and weak nuclear. Which choice is an example of the electromagnetic force?
Protons of similar charges are bound together and stabilized within an
atom's nucleus
It is responsible for nuclear beta decay and other similar decay processes
involving fundamental particles
This is the attractive force between matter; between two things that have
mass
Electrons bind with nucleus of an atom, due to the presence of protons

Suppose that two tanks, 1 and 2, each with a large opening at the top, contain different liquids. a small hole is made in the side of each tank at the same depth 1.57 m below the liquid surface, but the hole in tank 2 has 2.49 times the cross-sectional area of the hole in tank 1. (a) what is the ratio ρ1/ρ2 of the densities of the liquids if the mass flow rate is the same for the two holes? (b) what is the ratio rv1/rv2 of the volume flow rates from the two tanks? (c) at one instant, the liquid in tank 1 is 14.9 cm above the hole. if the tanks are to have equal volume flow rates, what height above the hole must the liquid in tank 2 be just then?
