You're trying to integrate dB, right? It forms the total magnetic field at Point P, yeah? You have to take into account the magnetic contributions of the metal strip to get that B value. To form the integral, you have to figure out which 'side' of the magnetic strip your magnetic...

Actually, I just remembered that rotational velocity = v/r, and that rotational acceleration = a/r. So yeah, if that helps, use it.

If I recall, rotational kinematics is full of ω's, and such associated terms. Step 1 is the formula for a period, and step 2 is just the application of centripetal motion. I think your work in regards to your rules/restrictions looks fine, but I strongly advise you not to take my word for it...

Homework Statement A point charge q = -2.9 μC moves along the z-axis with a velocity v→ = (+7.3 x 105 m/s) k . At the moment it passes the origin, what are the strength and direction of the magnetic field at the following positions? Express each field vector in Cartesian form. (a) At...

Force has units of kg * m/s2. Acceleration has units of m/s2. You're almost there. :)

I'd say that since R4 is pretty much the last resistor you get to, you might as well take it leg by leg. For example, have you noticed that R1 branch is parallel to the whole equivalent R234 branch? What do you know about the voltage across parallel branches? After that, it's just Junction...

I'd like to point out that an object in motion will remain in motion unless a constant acceleration is applied to it. That being said, No, velocity would not be the force you're looking. Here's two tips: 1. Check your units, as they do help verify you're doing something right if your...

Yeah, I got the right answer. Basically, I was confused whether the magnetic dipole moment was the same thing as the magnetic dipole or not, but it turns out it is. Thanks!

Homework Statement The Earth's magnetic dipole moment is 8.0 x 1022 A m2. (a) What is the magnetic field strength on the surface of the Earth at the Earth's north magnetic pole? You can assume that the current loop is deep inside the earth. 6.17e-5 T (b)How does this compare to 5.0 x...

Energy usually is in Joules, and you'll usually have problems that have answers of just Joules (J). I've seen other answers with units of kiloJoules (kJ = 1000 J), milliJoules(mJ = 0.001 J) and microJoules(μJ 1mJ/1000). Waves is a general topic, so I'm just going to be speaking generally...

Hey there! I'm sure you know the K of water - what you're looking for is the Ka value of HF. Have you not been given the value?

Basically, your total distance is 2 + 3 miles = 5 miles, and speed is 4 - (-3) = 7 mph. You have distance, speed and time. Surely you know the equation that makes it all work. Anyways, your most recent work looks fine.

Hey there! Just wanted to point this out in case you have that picky teacher or professor who devotes their life to signs - in regards to your acceleration, do keep in mind which way the clown is accelerating(you're saying he accelerates upwards with your value). Other than that, Post #4 is...

Just a note - if you're solving for t2, then making h negative if you have gravity as positive is totally fine. However, if you're solving for t, just a hint that you can't take the root of a negative expression and that you can do something about it.

Wow, that was simple. I kinda dumbed out there, but thanks for the help!
