2. Draw a ray diagram that shows the image produced when an object is located at the
principal focus of a converging lens.

"an open tank has the shape of a right circular cone. the tank is 6 feet across the top and 5 feet high. how much work is done in emptying the tank by pumping the water over the top edge? note: the density of water is 62.4 lbs per cubic foot."

In a voltaic cell, electrons flow from the (positive/negative) to the (positive/negative) terminal.

In the circuit shown below, with each bulb holding a resistance of 60 ohms, how many amps of current are flowing? express your number as a decimal.
