A golf ball is struck an initial velocity of 65.0m/s at an angle 12.0° above the horizontal. It lands at the same height from which it was struck. A) find the range of the gold ball

B) find the maximum altitude reached by He golf ball.

C) how long does it take to reach the maximum height?

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?

True or false when elements combine to form a mixture, the resulting chemical properties may be very different from those of the elements that make it.
