A loop is placed in a region where the magnetic field is changing. At t = 0 s the magnetic field is 1 T directed into the page. Over a period of 2 s, the field changes uniformly to 1 T directed out of the page.
Which of the following describes the direction, clockwise (CW) or counterclockwise (CCW), of the induced EMF in the 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.
