A tin can is filled with water to a depth of 38cm . A hole 20cm above the bottom of the can produces a stream of water that is directed at an angle of 30? above the horizontal.
a. Find the range of this stream of water.
b. Find the maximum height of this stream of water.
You hang the rod vertically and attach a 74 kg mass to the bottom, and you observe that the bar becomes 1.74 cm longer. From these measurements, it is possible to conclude the stiffness of one interatomic bond in titanium.
