so the answer is that since they are an equal distance away. that the force that a acts upon b is the same force that b acts upon a. answer 30N?

i think because magnet a is twice as strong, that magnet b is half of its strength. also i forgot a few parts of the question that might help it has twice the magnetic field strength.

well I'm not exactly sure. I'm looking in the chapter of magnetism in my book and i don't see any formula's. its weird. i went back a chapter and found coulombs which deals with force=(k)(q1q2)/d^2. i wasn't sure if it was right or now. if you could help me on a formula i could try and solve...

thats probably correct. this is a basic question. i think it is getting at coulombs law. i think the answer is 15N. not sure

Magnet A has twice the magnetic field strength of magnet B (at equal distance) at a certain distance and pulls on the magnet B with a force of 30N. Determine the force with which magnet B pulls magnet A. Could someone help me. I'm just starting physics in hs.

alright V= R * angular speed? Radius: C=pi*d 2meters=3.14*d .6366=d d=2r .6366=2r Radius=.318meters angular speed= 6.283185308 radians * ? is it 2meters?

Just checking these other problems 1)Bicycle has wheels with circumference of 2m. What is the linear speed of the bicycle when the wehels rotate at 1 rev/sec. 2m/s 2) A 10,000N vehicle is stalled 1/4 the way across a bridge. What are the two additional recation forces that are...

thanks. yea i just fixed it

thanks for the help. is this rotational velocity? earth sun 360 degrees = 6.28318531 radians 365 days or 31536000 seconds 6.28318531 radians/31536000 seconds 1.99x10^-7 rad/sec earth moon 360 degrees = 6.28318531 radians 27.3 days or 2358720 seconds 6.28318531 radians/2358720...

Earth Sun: (5.98x10^24)((1.5x10^11)^2) = 1.35x10^47 Earth Moon: (7.36x10^24)((3.84x10^8)^2) =1.09x10^40 so far so good?

ok i get Rotational Inertia: I=(2/5)(m)(r^2) Earth I=(.4)(5.98x10^24)((6.37x10^6)^2) I=9.71x10^37 Moon I=(.4)(7.36x10^34)((1.74x10^6)^2) I=8.91x10^34

i need help on this. how much greater is the angular momentum of the Earth orbiting about the sun than the moon orbiting about the earth? (using a ratio of angular momenta) angular momentum = rotational inertia x rotational velocity radius of Earth (equatorial) 6.37x10^6 radius of...
