You start an old record player and notice a bug on the surface close to the edge of the record. The record has a diameter of 12 inches and completes 33 revolutions each minute.
A.What is the speed of the bug in SI units?
B.What is the acceleration of the bug in SI units?
C.What would the bug's speed be if it were halfway between the center and the edge of the record?D.What would the bug's acceleration be if it were halfway between the center and the edge of the record?
The figure below shows an electric heater (R1 = 9.55W (Ohm)) and a toaster (R2 = 18.6W (Ohm)). As shown, E = 115V. What is the voltage across the heater? What is the current in the toaster?
