Two balloons are rubbed with a piece of wool and suspended by threads near each other, see figure below. (Assume the balloons are exactly the same as each other in terms of mass, size, and how vigorously they were rubbed). How will the balloons behave and explain your reasoning (be specific in terms of the angles the string will make)?
2) Repeat question 1, except the balloon on the left is now rubbed much more vigorously than the balloon on the right. How will the balloons behave and explain your reasoning (be specific in terms of the angles the string will make)?

You rub two 4.0-mg balloons with a wool sweater. The balloons hang from 0.50-m-long very light strings. When you attach the strings together at the top, the balloons hang away from each other each string making an angle of 37?with the vertical. Represent the situation with the force diagram for each balloon and determine the magnitudes of the forces that the balloons exert on each other. Will the relative magnitudes change if the charge on one balloon is two times...

Two balloons filled with air are each tied to very light 0.5-m-long strings. The loose ends of the strings are taped to the same position on a horizon tal bar. When both are equally rubbed with the same material they both develop a static charge and repel each other making an angle of 30° with respect to 2. the vertical. )With this experiment alone can you tell what type of charge is on the bal- loon? Explain. (b) Is this...

Two balloons filled with air are each tied to very light 0.5-m-long strings. The loose ends of the strings are taped to the same position on a horizontal bar. When both are equally rubbed with the same material they both develop a static charge and repel each other making an angle of 30º with respect to the vertical. Note: the mass of a rubber balloon is not given! If you find/assume a mass, cite a source! (a) With this experiment...

3. (III) Three blocks on a frictionless horizontal surface are in contact with each other as shown in Fig. 4-54. A force F is applied to block A (mass mA). (a) Draw a free-body dia- gram for each block. Determine (b) the acceleration of the system (in terms of mA, mB, and mc), (c) the net force on each block, and (d) the force of contact that each block exerts on its neighbor.

Each of these problems (Problems 1-4) is worth four points Definition: Two lines or curves are said to be normal to each other at their point of intersection if they intersect there at right angles or, equivalently, if their tangent lines at the point of intersection are 1. A well-known theorem in geometry states that a line which is tangent to a circle is perpendicular to the radius of the circle at the point of tangency. Use implicit differentiation to...

Two words or phrases in English are anagrams if their letters (and only their letters), rearranged, are the same. We assume that upper and lower case are indistinguishable, and punctuation and spaces don't count. Two phrases are anagrams if they contain exactly the same number of exactly the same letters, e.g., 3 A's, 0 B's, 2 C's, and so forth. Some examples and non-examples of regular anagrams: * The eyes / they see (yes) * moo / mo (no) *...

Notes Two players will face each other. They each decide independently to "cooperate" or "cheat". If they both cooperated, they each win two points. If they both cheated, nobody wins anything. one cheats, the cheater gets +3 and the cooperator loses a point. That wasn't very kind! One turn is defined as each player making a choice, and winning or losing some points as a result. Shared history against this player is available...
