At what angle is the rope held : What approximations or simplifying assumptions must you make in the calculations? (Note: Some of these choices are false because they are wrong physics!)

How to figure out how much power is dissipated : 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.

Care for the coffee as if it were water : What is the gauge pressure of the water at the pump? Suppose steady, laminar flow of water, no viscosity, and no air drag on the water jet. The acceleration of gravity is 9.81 m/s2.

What is the electric potential at a height of 1.20 : Long, long ago, on a planet far, far away, a physics experiment was carried out. First, a 0.250- ball with zero net charge was dropped from rest at a height of 1.70. The ball landed 0.400 later. Next, the ball was given a net charge of 7.85 and dropp..

What force is required to push it down : A helicopter is ascending vertically with a speed of 5.57. At a height of 124 above the Earth, package is dropped from a window. How much time does it take for the package to reach the ground?

How much work is necessary to eject a positive sodium ion : How many 185 W lightbulbs can you use in a 191 V circuit without tripping a 15 A circuit breaker? (The bulbs are connected in parallel, which means that the potential difference across each lightbulb is 131 V.)

What must be the length of the wire : Suppose you wish to fabricate a uniform wire out of 2.6 g of copper. If the wire is to have a resistance of R = 0.25 and if all of the copper is to be used, what must be the length of the wire in m and the diameter of the wire in mm.
