A CIRCULAR TRACK HAS A RADIUS OF 10 METERS FROM THE CENTER TO THE FIRST LANE. EACH LANE IS 2 METERS WIDE.

JASON RUNS 3 LAPS, THE FIRST IN LANE 1, THE SECOND IN LANE 2, AND THE 3RD IN LANE 3.

IF HE COMPLETES EACH LAP IN 4 MINUTES, WHAT IS HIS AVERAGE VELOCITY IN EACH LANE?

Steam enters an adiabatic diffuser at 150 kpa and 1208c with a velocity of 550 m/s. determine the minimum velocity that the steam can have at the outlet when the outlet pressure is 300 kpa.

Suppose you have three polarizing filters, with the second at an angle of 42∘ to the first and the third at an angle of 90∘ to the first. by what perfect will the original intensity of unpolarized light be reduced to after passing through all three filters?

Identify the correct relation showing that the radius r of the orbit of a moon of a given planet can be determined from the radius r of the planet, the acceleration of gravity at the surface of the planet, and the time τ required by the moon to complete one full revolution about the planet. determine the acceleration of gravity at the surface of the planet jupiter knowing that r = 71 492 km and that t= 3.551 days and r= 670.9 × 10^3 km for its moon europa.
