Now imagine that the coil is subjected to a series of experiments, that we will label 1, 2, etc., for clarity. at the beginning of both experiments 1 and 2, the magnetic field is initially 3.0 t. in experiment 1, the magnetic field is changed in 2.0 ms from 3.0 t to 6.0 t. in experiment 2, the magnetic field is changed in 2.0 ms from 3.0 t to 20.0 t. what is the ratio of the average emf observed in each case, emf1 / emf2?

Asmall grinding wheel has a moment of inertia of 4.0×10−5 kg⋅m2 . what net torque must be applied to the wheel for its angular acceleration to be 150 rad/s2 ?

4. now look at the green lines you created by connecting the three boiling point data points and the three melting point data points. for each of these lines, describe any trends you see. 5. locate the elements on your periodic table that you circled in green on your graph. what term or description would you use to identify these elements with respect to the periodic table? 7. using the room temperature line (orange line) and your periodic table, make lists that identify the state of matter (gas, liquid, or solid) in which each element you plotted exists at room temperature. explain your answers.

1. explain how you calculate the net force in any direction on the box. 2. suppose an upward force of 15n is added to the box. what will be the net vertical force on the box? 3. what force could be applied to the box to make the net force in the horizontal direction zero? explain. 4. suppose a force of 25n to the right is added to the box. what will be the net force to the right?
