Problem 4 (20 points): The power absorbed by an element is equal to the product of the voltage across it and the current passing through it (in the direction from high to low potential), i. e. P = V × . For a resistor, this value is always positive (implying that the resistor "absorbs" power). The value will be negative if an element "delivers" power (which is usually but not always the case for a power source). In the following circuits, state whether the 5V power source is "absorbing power from" or "delivering power to" the circuit. Find this power.

Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?
