What is the first velocity of the car with two washers at the 0.25 meter mark?
m/s
Calculate the first and second velocities of the car with
two washers attached to the pulley, using the formulas
V1 = 0.25 m/ty, and
v2 = 0.25 m/(t2- +1)
where tq and t2 are the average times the car took to
reach the 0.25 and the 0.50 meter marks. Record these
velocities, to two decimal places in Table E.
What is the second velocity of the car with two washers
at the 0.50 meter mark?
m/s
l

What is the average speed of a car that travels 40 mph for 1 hour and 60 mph in another hour?

When is a current produced? when the terminals of an electrochemical cell are connected by a wire if the electric circuit is opened in an electrochemical cell if the electrolyte is removed from an electrochemical cell when the electrodes are reversed in an electrochemical cell
