Formulate a rule for predicting how the current through (he battery would change (i.e., whether it would increase, decrease, or remain” the same) if the number of bulbs connected in parallel were increased or decreased. Base your answer on your observation of the behavior of the two-bulb parallel circuit and the model for current.
What can you infer about the total resistance of a circuit as the number of parallel branches is increased or decreased?

- 20. Two small conducting spheres are placed on top of insulating pads. The 3.7 × 10-10 C sphere is fixed whie the 3.0 × 107 C sphere, initially at rest, is free to move. The mass of each sphere is 0.09 kg. If the spheres are initially 0.10 m apart, how fast will the sphere be moving when they are 1.5 m apart?arrow_forwardpls help on allarrow_forwardpls help on thesearrow_forward

Mount Everest, Earth's highest mountain above sea level, has a peak of 8849 m above sea level. Assume that sea level defines the height of Earth's surface. (re = 6.38 × 106 m, ME = 5.98 × 1024 kg, G = 6.67 × 10 -11 Nm²/kg²) a. Calculate the strength of Earth's gravitational field at a point at the peak of Mount Everest. b. What is the ratio of the strength of Earth's gravitational field at a point 644416m below the surface of the Earth to a point at the top of Mount Everest? C. A tourist watching the sunrise on top of Mount Everest observes a satellite orbiting Earth at an altitude 3580 km above his position. Determine the speed of the satellite.arrow_forward

As the distance between two charges decreases, the magnitude of the electric potential energy of the two-charge system: a) Always increases b) Always decreases c) Increases if the charges have the same sign, decreases if they have the opposite signs d) Increases if the charges have the opposite sign, decreases if they have the same sign 7. To analyze the motion of an elastic collision between two charged particles we use conservation of & a) Energy, Velocity b) Momentum, Force c) Mass, Momentum d) Energy, Momentum e) Kinetic Energy, Potential Energyarrow_forward
