In: Physics
In each of the scenarios below, two spheres of the same size and shape hang from a common attachment point.
In each of the scenarios below, two spheres of the same size and shape hang from a common attachment point. Each sphere is electrically charged and is either perfectly conductive or perfectly insulating, as indicated in the key below. The magnitude of charge Q is greater than the magnitude of charge q.
Each pair of spheres is allowed to swing freely and comes to rest in some equilibrium position. In each scenario, determine whether the spheres come to rest in contact, or separated by some distance. Assume that the weight of the spheres is small enough that electrostatic forces are significant.

If the size and shape of two objects A & B are the same, but
object B has a smaller mass: (a) for which object would the beta
factor be larger? Justify your answer. (b) Which object would have
a larger terminal velocity? Justify your answer. (c) Using a-b: if
you dropped styrofoam ball and a steel ball of the same size/shape
off a tall building, which would land land first, discounting air
resistance? How about including air resistance? beta=...

Two ramps, each with the same shape angle, and height from the
base contain two different objects. One ramp has a solid sphere
located at the top while the other ramp has a solid cube located at
the top. The mass of the sphere is equal to the mass of the cube.
The objects are released from the same height. The sphere rolls
without slipping, and the cube travels without friction. After
leaving the ramp, which object will travel higher?...

1. Two streams (Brimer and Standifer creeks) located in the same
watershed are similar in size/shape and most habitat conditions
(e.g., temperature, dissolved oxygen, channel substrate); however,
they exhibit different pH values. Brimer Creek has a mean pH of
6.1, whereas Standifer Creek has a pH of 5.6. A stream ecologist
wishes to determine whether the pH has an influence on the local
distributions of benthic macroinvertebrates (annelids, crustaceans,
insects) in the two streams. Two study sites were established (one...

Two titanium spheres approach each other head-on with the same
speed and collide elastically. After the collision, one of the
spheres, whose mass is 200 g, remains at rest.
(a) What is the mass of the other sphere?
(b) Assume that the initial speed of each sphere was 2.2 m/s. What
is the speed of the two-sphere center of mass?

A bag contains 12 balls of the same shape and size.
Of these, 9 balls are blue, and the remaining 3 balls are
red.
Suppose that you do the following iterative random experiment:
In each iteration, 5 balls are removed randomly (without
replacement) from the bag, in such a way that any 5 balls in the
bag are equally likely to be the 5 balls that are removed. After
doing this, you check whether among the 5 removed balls there...
