Two long straight parallel wires are oriented north-south. Both wires carry constant current due North and are 20cm apart. The current in one cable is 30A and in the other 40A . a) Determine the magnitude of the total magnetic field induced by the two cables midway between them. b) determine the position between the cables where the total magnetic field induced by the cables is zero. Give your result as the distance from the 30A cable.

A proton is released from rest inside a region of constant, uniform electric field ?1 pointing due north. 34.8 s after it is released, the electric field instantaneously changes to a constant, uniform electric field ?2 pointing due south. 8.49 s after the field changes, the proton has returned to its starting point. What is the ratio of the magnitude of ?2 to the magnitude of ?1? You may neglect the effects of gravity on the proton.

The route followed by a hiker consists of three displacement vectors  ,  , and  . Vector  is along a measured trail and is 2670 m in a direction 27.0 ° north of east. Vector  is not along a measured trail, but the hiker uses a compass and knows that the direction is 34.0 ° east of south. Similarly, the direction of vector  is 42.0 ° north of west. The hiker ends up back where she started, so the resultant displacement is zero, or  +  +  = 0. Find the magnitudes of (a) vector  and (b) vector  .

Variables This week, you studied different kinds of variables. Refer to the South University Online Library and select an empirical article that covers a topic of interest to you and has clearly identified variables, ensuring that the study is recent (i.e., conducted within the past five years). Describe the methods used. In addition, discuss the variables and scales used in each study. At the conclusion of your discussion, describe how you would code these variables in Minitab.

1. You are trying to grow your ficas plants in the basment of your home. The ficas in a south-facing window and you give it 1 cup of water in the morning everyday. Still your plant is unhealthy. Propose two hypotheseses about this observed phenomenon, along with two experiments to test them. (Hint: how many varibales should you change in an expieriment?)

2. Draw the general structure of the atom, labeling all parts.
