- How do you find the area of this? I had to do an experiment where you take a styrofoam cup and poke a flashlight through the bottom of it, then shine the light onto a wall from different distances and measure the diameter. I have to calculate the area. It it just pi*r^2? That's what I did, but then I've seen someone else use 4*pi*r^2 and that confused me. I want to make sure I done it right.Use a scientific calculator to calculate Delta L_fS for D1 = 20 meters and D2 = 40 meters. I can't believe I have to ask this, but I can't even figure out how to input that in the calculator.nework @@ 2 W S Question 9 of 14 X mmand Your answer is partially correct.

[-/1 Points] DETAILS MY NOTES PRACTICE ANOTHER In a popular amusement park ride, a rotating cylinder of radius R = 2.00 m is set in rotation at an angular speed of 6.10 rad/s, as in the figure shown below. The floor then drops away, leaving the riders suspended against the wall in a vertical position. What minimum coefficient of friction between a rider's clothing and the wall is needed to keep the rider from slipping? Hint: Recall that the magnitude of the maximum force of static friction is equal to u̟n, where n is the normal force-in this case, the force causing the centripetal acceleration. R Need Help?

- I’m wondering if I can get some help with a previous asked question... the answer that was explained to me differs from the answer in my textbook. I just want to make sure I’m understanding how to do this properly...the answer in the book says 262 nT where the answer given by a Bartleby expert was 2.08x10^-9T. Would you mind looking this over to see what the discrepancy is? Thanks! I’ll attach a photo of the worked out solution... The question reads: A current path shaped as shown in the figure below (in photo) produces a magnetic field at P, the center of the arc. If the arc sub tends an angle of theta= 30degrees and the radius of the arc is .600m, what are the magnitude and direction of the field produced at P if the current is 3.A?-9.22 was the answer I got and it is saying it's wrong.
