An airplane needs to head due north, but there is a wind blowing from the northeast at 70 km/hr. The plane flies at an airspeed of 750 km/hr. To end up due north, the pilot will need to fly the plane 4.0 degrees of north. (Give your answer to the nearest tenth of a degree)

Carbon 14 is a naturally occurring stable

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.

What are the dimensions of the cross section that passes through the points a, f, g, and d?
