Hi everyone, Could someone please show me how to prove this? Homework Statement Determine |A U B| in terms of |A| and |B| assuming that A and B are disjoint Homework Equations The Attempt at a Solution I know that A U B must be finite because A and B are disjoint, but...

Thank you very much Regards

Well, in the problem it states that the two objects are separated by .420 m. Is that what you mean? Thus, the 41.0 object is at .420 m, right? Thank you

Thank you very much Regards

[SOLVED] gravitational field Homework Statement How much work is done by the Moon's gravitational field as a 1100kg meteor comes in from outer space and impacts on the Moon's surface? Homework Equations W=GMm/r The Attempt at a Solution W=6.67 X 10^-11(6 X 10^22)(1100kg)/1.5 X...

Thank you I just need it in terms of i and j. So, wouldn't that be correct the way it is? F32 is negative and F13 is positive, right? Thank you

Thank you The triangle is placed in the second quadrent, where m3 is at (0,0) m2 is at (-4,0)m and m1 is at (0,3) Does this look correct? F32=-6.67X10^-11Nm^2/kg(5.5kg)(4kg)/4^2= -9.2 X 10^-11i F13= -6.67X10^-11Nm^2/kg^2(4)(2)/3^2= 5.9X10^-11j Thank you

It's in the middle. Is that what you mean? So, wouldn't you just take 6.67 X 10^-11(145)(41/2)/.42^2? 6.67 X 10^-11(445kg)(41.0kg)/2/(.42)^2? Thank you

Hi everyone, Could someone please help me with this problem? Homework Statement Three uniform spheres of mass m1=2.00kg, 4.00kg, and m2=5.50 kg are placed at the corners of a right triangle. Calculate the resultant gravitational force on the 4.00 kg object, assuming the spheres are...

Thank you very much For part a., would I just take 4.7 X 10^-6 and divide it by 2? Thank you

Thank you very much Could you please tell me if a. looks correct? For part b., would you just take the first one plus the middle one plus the third one and set it equal to the total force and solve for the middle one? Thank you

Yes, that was correct Thank you very much Regards

Thank you very much Isn't 11.5 just the time or is that also the period? Thank you

Hello everyone, Could someone please help me with this problem? Homework Statement A 145kg object and a 445kg object are separated by .420m. a. Find the net gravitational force exerted by these objects on a 41.0kg object placed midway between them. b. At what position can the 41.0kg...
