Calculate the first and second velocities of the car with three washers attached to the pulley, using the formulas v1 = 0.25 m / t1, and

v2 = 0.25 m / (t2 – t1)

where t1 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 first velocity of the car with three washers at the 0.25 meter mark?

m/s

What is the second velocity of the car with three washers at the 0.50 meter mark?

m/s

0.13 and 0.36

Explanation:

Just did it

The correct answer is 0.19 at 0.25 m and 0.45 at the 0.50 m mark

Explanation:

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
