What is the first velocity of the car with four washers at
the 0.25 meter mark?
m/s
Calculate the first and second velocities of the car with
four washers attached to the pulley, using the formulas
V1 = 0.25 m/ty, and v2 = 0.25 m/(t2-t1)
where to and ty 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 four
washers at the 0.50 meter mark?
m/s

8. why do radio telescopes convert radio waves (analog signals) to electrical (digital) signals for analysis? (hint: what did the article say about the advantages of digital signals? )

In a stagnant pool of water, a crayfish may spend much of its time lying with one side of its carapace near the surface of the water. in this position, it will move the walking legs on that side in a rhythmic back-and-forth motion. explain the likely function of this behavior.
