Identify the true statements about surface tension.
molecules along the surface of a liquid behave differently than those in the bulk liquid.
mercury has a lower surface tension than water.
cohesive forces attract the molecules of the liquid to one another.
surface tension increases as the temperature of the liquid rises. w
ater forming a droplet as it falls from a faucet is a primary example of surface tension.

What should the power status of a circuit be when measuring resistance with an ohmmeter?

Which best represents the law of conservation of mass ?

Afisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. it takes a time of 2.20 s for the boat to travel from its highest point to its lowest, a total distance of 0.670 m . the fisherman sees that the wave crests are spaced a horizontal distance of 5.80 m apart. (a) how much is the wavelength? (b) find the period of the wave. (c) how fast are the waves traveling? (d) what is the amplitude a of each wave?
