An eagle descends steeply onto its prey. its weight (the gravitational force on the eagle), of magnitude 60.0 n, points downward in the -y-direction. the left force exerted on the eagle's wings by the air, also of magnitude 60.0 n, is at an angle of 20.0∘ from the vertical (the +y-direction) and 70.0∘ from the +x-direction. the drag force (air resistance) exerted on the eagle by the air has magnitude 15.0 n and is at an angle of 20.0∘ from the -x-direction and 70.0∘ from the +y-direction. find the x- and y-components of the net external force f⃗ on the eagle.

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.
