Asquare loop of wire surrounds a solenoid. the side of the square is 0.1 m, while the radius of the solenoid is 0.025 m. the square loop has a resistance of 30 w. the solenoid has 500 turns and is 0.3 m long. the current in the solenoid is increasing at a constant rate of 0.7 a/s. what is the current flowing in the square loop?

You are a researcher for a golf club manufacturer. you are given two identical looking cubes of a metal alloy. you are informed that they are made of the exact same material, but one is crystalline, whereas the other is amorphous. it is your job to determine which one is amorphous this one is more stress-resistant and is useful in reinforcing golf clubs. which of the following is the best way to determine which is which? a. determine the density of each cube. the more dense one is the amorphous solid. b. melt both cubes and look for a broader range of melting temperatures. the one that melts over a broader range of temperatures is the amorphous solid. c. determine the density of each cube. the less dense cube is the amorphous solid. d. melt both cubes and measure the range of melting temperatures. the one that melts over a narrower range of temperatures is the amorphous solid.
