A circuit(attached picture visualizing it) has a 10v source and two parallel paths in the circuitry. One
path has a pair of resistors of 20 and 30 Ohm
capacity in series- the other path has a single 50
Ohm Resistor. What is the total resistance
through the circuit, and what is the current
(amps) through each of the parallel paths.

Astone dropped into a well is heard to strike the water after 8seconds. find the depth of the well if the velocity of sound is 350m/s

Astone is dropped with no initial velocity from the top of a cliff and hits the ground a time of 3.9 s later. what is the height of the cliff, in units of meters? you may assume that air resistance is negligible. give the answer as a positive number question 15 a figure skater is rotating at a rate of 200 revolutions per minute. what is the angular speed, in units of rad/s? 200 o 20.9 12000 o 3.33
