I know that I have to use Ohm's law combined with Kirchhoff's Voltage to set up the two loop equations and one node equation and to calculate the unknown currents I1, I2, and I3. The diagram and descriptions...

multiple choice question a. No. Larger forces always produce larger torques. b. Yes. If the larger force is farther from the fulcrum than the smaller mass. c. Yes. If the smaller...

I believe these are the knowns: X- Vxi= 230cos40 (176.19), vxi = vxf, ax=0. Y- Vyi= 230sin40 (147.84) vyf= -147.84, ay= -9.8. I used the equations vyf=vyi + at, to find t. I used Δx=vxit...

I need to determine the acceleration factor, do I need to find time first and use the equation a=(vf-vi)/t? Or can I just use the acceleration factor equation f=|a/g|

Application: Merry-go-round. how fast can you spin the merry-go-round before the kids slip off? treat the merry-go-round as a flat disk w?out bars. (give answer in revolutions per second). note, this...

An electron is moving horizontally to the right with speed 4 multiply 106 m/s. What is the magnetic field due to this moving electron at the indicated locations in the figure? Each location is d =...

Consider two flasks, the first flask has 2.00L of hydrogen at a pressure of 475 torr, the second has 1.00 L of nitrogen at a pressure of 0.200 atm. If the stopcock between the two flasks is opened...

I calculated the electric field to be <6.95e-5 ,6.95e-5, 6.95e-5> at location < 2 ✕ 10-3, 2 ✕ 10-3, 2 ✕ 10-3 > m, due to the proton. At a particular instant a proton is...

A ball is thrown horizontally off the roof of a building 50m tall. the ball is thrown with a velocity of 20m/s ? How far from the bottom of the building does the ball land ? &n...

I feel like this should be easy and I'm making this harder than it should be. A baseball player throws a baseball into the air at a height of 3.00 m above the release point, the ball...
