A final thought experiment: What happens to the relationship between their linear and rotational velocities if the merry-go-round Is twice as big and the kid on the outside is twice as far away from the other student? Does the radius of the circle make a difference? Can you propose an equation that will relate the rotational velocity of an object with the radius of the circle and with the object’s linear velocity? Your equation will have only these three variables: 1) rotational velocity (v); 2) radius ®; and 3) linear velocity (ω).

An insulated 40 ft^3 rigid tank contains air at 50 psia and 120°f. a valve connected to the tank is now opened, and air is allowed to escape until the pressure inside drops to 25 psia. the air temperature during this process is kept constant by an electric resistance heater placed in the tank. determine the electrical work done during this process.

Nacidified solution was electrolyzed using copper electrodes. a constant current of 1.18 a caused the anode to lose 0.584 g after 1.52 ✕ 103 s. given that the charge of an electron is 1.6022 ✕ 10−19 c, calculate avogadro's number. assume that copper is oxidized to cu2+ ions.
