Okay. Thank you. I'll think about this.

Is this suggesting that there is a delay for the light to reach the rocket because it's traveling?

I appreciate all the help. The question is kind of difficult for me to answer. I'm not quite sure what it's asking. Which time are we seeking in the question in the OP? If there was a clock on the Earth and one on a spaceship, and the question was "What would a person on the spaceship read on...

In the rocket rest frame, the proper time is 6 minutes? Is there an easy definition or trick for proper time that will help me apply it correctly next time? It's now my understanding that the proper time is in the moving frame that moves with respect to the rest frame that we use. So if the...

I'm a little confused. Instead of intervals I thought of a clock. When the person on Earth has a clock that shows 6 minutes, the person on the rocket has a clock that shows 4.8 minutes.

The time in the rocket moves slower and I treat that as the proper time because it's the rocket that's moving. This resulted in 4.8 min.

I think 4.8 min is correct. Am I right?

A person on Earth signals with a laser beam at 6 minute intervals. Another person on a rocket moving away from Earth at 0.600c detects the signals. At what time intervals does the person on the rocket receive the signals from the Earth. The formula we use is: Δt=Δto/sqrt((1-u2/c2)) u = 0.600c...

Thank you for responding. I didn't realize it has to do with the chemical reaction.

So I understand that a battery consists of an anode, cathode, and electrolyte. Question: What is the function of the electrolyte? Can we use a conductor instead of an electrolyte like some kind of metal? If so, why don't we? Now for a penny and nickel battery stacked on top of each other you...

Thank you Simon. Is the symbol ∇ used in Maxwell's equations the same as the symbol ∇ used in calculus for gradient?

1. I think it's the magnetic field passing through a surface. Thank you for helping. The physics course I took only required integral calculus. I still need to complete my math courses before I fully understand differential equations :cool:

1. Space around which there exists a magnetic force (I'm assuming it can vary in strength too) 3. Yep.

So a changing magnetic field doesn't necessarily mean changing magnetic flux, it could mean changing magnetic field strength? Are those the same thing, no? By time varying electric field, are you referring to current? As for which education level, college but I just wanted simple answers...

Thank you. Seems to contradict what Simon said. Hmm which answer is correct?
