The diagram shows a 2.0 kilogram cart traveling at a constant speed in a horizontal circle of radius 3.0 meters. The magnitude of the centripetal force of the cart is 24 newtons. Use this information to answer the following question(s). A. Velocity is directed toward point B, and the centripetal force is directed toward point A.

B. Velocity is directed toward point B, and the centripetal force is directed point D.

C. Velocity is directed toward point C, and the centripetal force is directed toward point A.

D. Velocity is directed toward point C, and the centripetal force is directed toward point D.

The heater element of a 120 v toaster is a 5.4 m length of nichrome wire, whose diameter is 0.48 mm. the resistivity of nichrome at the operating temperature of the toaster is 1.3 × 10-6 ω·m. the toaster is operated at a voltage of 120 v. (a) what is the power drawn by the toaster? (b) if the cost of electricity is 12 ¢ per kilowatt-hour, and it takes 2 minutes to toast bread, how much does it cost for toasted bread? (c) when the heater element is at room temperature, is the resistivity in the nichrome wire greater than, less than, or equal to it’s resistivity when at operating temperature? explain.
