Calculate resistance with cross-sectional area?
Hello, normally you calculate the cross-sectional area of a cylinder/wire like this: A = r²π. However, in this problem (32a), only r² was used… Why?
All moments should be calculated: Why are F2 and L2 not considered in this example? Moment = Force x Lever Arm… Does it have something to do with the fact that F2 points away from the pivot point and thus acts in the other direction? it's been resolved haha thanks
We have a regulator with a striking mechanism hanging on the wall. A small adjusting screw on the pendulum adjusts the length or height of the pendulum weight, and thus the clock's accuracy. I'm actually very precise. However, I've noticed for a while now that the clock sometimes runs a little faster, then slightly slower…
What do you have to do for this task? Task 6 is what I'm referring to. I need it for work tomorrow!
Where in Maxwell’s equations is the speed of light? That electromagnetic waves have a maximum speed (of about 300,000 km/s)
Could we program an AI that would surpass us in intelligence and find the formula for the universe?
Just look. In the length of the wire there is also a π because the length l results from the number of turns and the circumference of the plastic coil.
In the end, this π in the length calculation with the π from the cross-sectional area calculation.
Confirm me again in my view, first write all formulas, to write into a final formula and to use numbers at the end (I have not whether the result is correct, but the numerical value of the specific resistance ρ has already been misused in the solution — 0.0017 vs. 0.017 )
