In a vacuum, a 74 gram feather will fall to the Earth at the same rate (acceleration) as a 7.26 kg bowling ball. Which one will hit the ground first?
Then use Newton's 2nd Law of Motion to explain which object (the feather or
the bowling ball) experiences a greater force due to gravity.

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.
