Let n represent the number of similar resistors in a circuit. Each resistor has a resistance of r. When the resistors are connected in parallel the circuit has a total resistance of R.

A vector R is resolved into its components, Rx and Ry. If the ratio of is 2, what is the angle that the resultant makes with the horizontal?

What are ionic bonds? A. Bonds that form when any two atoms come in contact. B. Chemical bonds that form from the attraction of negative and positive ions. C. Chemical bonds that form when atoms share electrons equally. D.

What effect do oceans have on the temperature of coastal areas? A. Ocean breezes warm the coastal land constantly. B. Ocean currents always cool a coastline. C. Ocean winds prevent extremes of temperature on coastal lands. D.

A solenoid is formed by winding 23.0 m of insulated silver (resistivity 1.59 * 10-8 Ω·m) wire around a hollow cylinder. The turns are wound as closely as possible without overlapping, and the insulating coat on the wire is negligibly thin.

How would you describe the two projectors used to screen a three-dimensional movie? A. Both projectors have vertical polarizers. B. One projector has a vertical polarizer and the other has a horizontal polarizer. C.

A roller coaster has a mass of 500 kg. It drops from rest at the top of a hill that's 57 m tall. How fast is it going when it reaches the bottom? Acceleration due to gravity is g = 9.8 m/s2.
