Acircular coil 18.0 cm in diameter and containing nine loops lies flat on the ground. the earth's magnetic field at this location has magnitude 5.50×10−5t and points into the earth at an angle of 54.0 ∘ below a line pointing due north. a 6.30-a clockwise current passes through the coil. part a determine the torque on the coil. express your answer using three significant figures and include the appropriate units.

Asap time is ! best answer gets compose at least one well-developed paragraph on the following: define the term concurrent powers, and give an example of a concurrent power of government.

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.
