What Is the Spider's Average Speed and Magnitude of Average Velocity?

AI Thread Summary
The discussion revolves around calculating the average speed and magnitude of average velocity of a spider crawling from corner A to corner B. The spider covers a total distance of 48 meters (27 meters from A to C and 21 meters from C to B) in 30 minutes. Average speed is determined by dividing the total distance by the time taken, while average velocity is calculated using the displacement (the straight-line distance from A to B) divided by the same time. The conversation also includes a brief off-topic exchange about the University of North Dakota. Overall, the focus remains on solving the spider's movement problem.

I am having a problem with the following question:
A spider crawls from corner A to corner B in 30 minutes. The distance between AC (C chosen as a half-way point) is 27 meters, the spider turns right and the distance between CB is 21 meters. a) What is its average speed? and b) what is the magnitude of its average velocity?
Thanks for any help!

hey Bianna, is UND Notre Dame or North Dakota (my alma) or something completely different?

I go to University of North Dakota
 
For average speed, divide the distance traveled by the time; for average velocity, divide the displacement by the time.
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
