Part E If you were standing on the equator, at oº latitude, Polaris would appear to be directly on the horizon, with an altitude of
0°. If you were standing on the North Pole, at 90° latitude, Polaris would appear to be at zenith, or 90°. How does the
altitude you determined for Polaris using hand measurements compare to the latitude of your location, which you
determined in Task 1?

Explain what happens at the saturation point when adding salt to water at room temperature.

16. a brave but inadequate rugby player is being pushed backward by an opposing player who is exerting a force of 800 n on him. the mass of the losing player plus equipment is 90.0 kg, and he is accelerating at 1.20m/s2 size 12{1 "." "20"" m/s" rsup { size 8{2} } } {} backward. (a) what is the force of friction between the losing player’s feet and the grass? (b) what force does the winning player exert on the ground to move forward if his mass plus equipment is 110 kg? (c) draw a sketch of the situation showing the system of interest used to solve each part. for this situation, draw a free-body diagram and write the net force equation.

At what time would the magnitude of the velocity reach 36.00 km/hr
