Atrough is filled with a liquid of density 815 kg/m3. the ends of the trough are equilateral triangles with sides 6 m long and vertex at the bottom. find the hydrostatic force on one end of the trough. (use 9.8 m/s2 for the acceleration due to gravity.)

Ahypothesis is? close agreement by competent observers of observations of the same phenomena. a guess that has been tested over and over again and always found to be true. an educated guess that has yet to be proven by experiment. the long side of a right triangle. a synthesis of a large collection of information that includes guesses.

Acup of coffee sits on the dashboard of an automobile. the car goes around a sharp curve. even though you hold the cup still, coffee still splashes out. this can best be explained due to a) density. b) friction. c) gravity. d) inertia.

True or false graphs must include scales that increase by the same amount
