Ahomeowner uses a snowblower to clear his driveway. knowing that the snow is discharged at an average angle of 40° with the horizontal, determine the initial velocity v0 of the snow when the dimension a = 19 ft. (round the final answer to two decimal places.)

A1500 w electric heater is plugged into the outlet of a 120 v circuit that has a 20 a circuit breaker. you plug an electric hair dryer into the same outlet. the hair dryer has power settings of 600 w, 900 w , 1200 w, and 1500 w. you start with the hair dryer on the 600 w setting and increase the power setting until the circuit breaker trips. under what setting does the circuit breaker trip.
