Nevermind. I got it and it was positive x. How is that so, though? I swear it can be both positive and negative x. I even drew it out!

So, from what I can gather, the answer is +x or -x, it can be either one can't it?

Homework Statement A plane electromagnetic wave, which is polarized in the positive y-direction, propagates in the negative z-direction. What is the direction of the magnetic field of this wave? Homework Equations My choices are: +z direction. -y direction. -x direction. +y...

Nevermind. I figured out the problem.

Thanks for your help!

Thanks! What about number 2?

This is for Physics II. I understand how to lump the resistances together, i.e. parrallel and perpendicular. However, I am not sure how to calculate the amps. For example, for the left side, do I take the 5 volts and divide it by 0.88 ohms and then add that to 10 volts divided by 3.3 ohms (the...

Homework Statement Please help!:confused: My problem is: (with figure attached, the figure explains the majority of the ptorblem) (a) What is the size and direction of current i1 in Fig. 27-40, where each resistance is 2.2 and V1 = 18 V? (b) What is the power of the 18 V battery, and...

I still get SQRT (107). Are you sure about SQRT(62)?

The answer I got for number 1 is SQRT (107), is this correct? What about number 2?

Hi, I need some help on these problems. I'm not sure what to do. 1 Find the area of the plane with vector equation r(u, v) =< 1+v, u-2v, 3-5u+v> that is given by 0<u<1, 0<v<1. So far, I took the partial derivatives with respect to u and v. I don't know if I was supposed to or not and I'm...

Please help! My problem is: (with figure attached, the figure explains the majority of the ptorblem) (a) What is the size and direction of current i1 in Fig. 27-40, where each resistance is 2.2 and V1 = 18 V? (b) What is the power of the 18 V battery, and is energy being supplied or...

Spacecraft Voyager 2 (of mass m and speed v relative to the Sun) approaches the planet Jupiter (of mass M and speed V relative to the Sun) as shown in Fig. 10-60. The spacecraft rounds the planet and departs in the opposite direction. What is its speed, relative to the Sun, after this...
