Still could use a reply, to my last post (especially about the 90deg). Thanks

1). Aren't both torques the same, so I would double it? 2). Isn't the area A= [(pi)*(R)^2]? 3). I don't think direction is important, because it just wants the magnitude of torque. Let me know I made any bad assumptions on these 3. **Also, can someone confirm that the angle in my calculation...

For r, I did the square root of [(L)^2+(a/2)^2].

So my angle is 90deg, and I didn't need to solve for it?

Homework Statement Note getting the right answer. Question: a). What is the magnitude of the torque on the circular current loop in the figure? b). What is the loop's equilibrium position. Homework Equations Torque = [(I*A)*B*(sin(theta))] L= 2.0cm a= 2.0mm Iwire = 2.0A Iloop...

When you wrote w, did you mean omega or weight?

I used the 1000m/s^2 as acceleration instead of gravity, unless the 1000m/s^2 was meant to be used to somehow solve for vi.

Homework Statement I did this problem in my book, then checked the answer, and it showed what must be a typo for answer a (acceleration should be m/s^2 not m/s), and answer c just makes no sense. "When jumping, a flea reaches a takeoff speed of 1.0m/s over a distance of 0.50mm." a. What...

Thanks for the help

The full question says: "A rock climber stands on top of a 50-m-high cliff overhanging a pool of water. He throws the two stones vertically downward 1.0s apart and observes that they cause a single splash. The initial speed of the first stone was 2.0m/s." a. How long after the release of...

yeah, but the equation I stared from was linear horizontal motion, and I used it for linear vertical motion. Xf = Xi + vi (change in time) + ½ a (change in time)^2 Yf = Yi + vi (change in time) + ½ ay (change in time)^2 where ay = afreefall= -g= -9.8m/s^2 Which should look like...

Homework Statement What did I do wrong? My book's answer says the initial velocity when the rock was thrown straight down off a cliff was vi= 15.2m/s, but I got vi= -15.2m/s. What is the initial speed of stone 2? yi= 50m yf= 0m ti= 0s tf=2.0s ay= -9.8m/s^2 Vyf= 0m/s Vyi= Unknown...

Yeah, the km/s was a typo, i was looking at #2's units when I was typing.

Homework Statement Question 1. Find the sum of the measurements 896 g, 55.2 g, 0.63 g, and 3.5 g. Question 2. How many significant figures are in the measurement 60,000,000 km/s?Homework Equations The Attempt at a Solution Attempt on #1: 955.33 g (wrong ans) Attempt on #2: 2 sigfigs (wrong...

Yeah, I have that from when I bought it, I was thinking more about lessons that teach how to use the calculator with a specific focus on physics. At least I can use the file to search for things instead of flipping through the pages. Thanks for the reply tho.
