A student has 500 identical, rectangular sheets of paper. The mass of 1.0m of the paper is
0.080 kg

(a) Using a metre rule, she measures the length of one sheet of paper and its width. The length is
0.300 m and the width is 0.210m.

(i) Calculate the mass of one sheet of paper.

(ii)
The student makes a single pile of the 500 sheets of paper.
With a metre rule, she measures the height of the pile. The height of the pile is 0.048 m.
Calculate the density of the paper.

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.

Aspecified volume of space contains an electric field for which the magnitude is given by e=e0cos(ωt). suppose that e0 = 20 v/m and ω = 1.0 × 107 s−1. part a what is the maximum displacement current through a 0.80 m2 cross-sectional area of this volume? express your answer with the appropriate units. idisp,max i d i s p , m a x = nothing nothing request answer part b how would this area have to be oriented relative to the electric field to get this maximum displacement current?
