Please Help - Circuit 1 with Resistors and Battery Hi, I'd like to revive this thread. I'm solving the exact same problem but with different values. The last question is asking me the following: 6) If the value of the resistor R2 were doubled, how would the value of the resistor R3 have to...

Thank you Spinnor, I finally got it! I appreciate your help. Cheers

Thank you both for your replies. Spinnor, I agree with you, the wording on that last question is definitely incorrect, thanks for pointing that out. Now, I am not so sure how I would go about using conservation of momentum to find out how the energy would be shared between the different...

Homework Statement An object with total mass mtotal = 8.6 kg is sitting at rest when it explodes into two pieces. The two pieces, after the explosion, have masses of m and 3m. During the explosion, the pieces are given a total energy of E = 48.0 J. 1) What is the speed of the smaller piece...

Doc Al, thanks for your prompt reply! This is an online system, and it only took the answer as being correct once I excluded the Y component of the Tension. But I agree with you, it should be factored in there. All the equations I presented above, have already been accepted by the system...

Homework Statement A mass m = 16.0 kg is pulled along a horizontal floor, with a coefficient of kinetic friction μk = 0.14, for a distance d = 8.3 m. Then the mass is continued to be pulled up a frictionless incline that makes an angle θ = 38.0° with the horizontal. The entire time the...

Thanks for pointing that out! Fixed. I am the worst for making dumb mistakes like that. I appreciate your quick reply, I can now finish my homework. :)

Ohh...I feel so dumb now. lol. So, will it be just the change in potential energy for Δh? So final equation is W=m*g*Δh=m*g*(30-30*cos(θ)) ? So final equation is W=m*g*Δh=m*g*(13-13*cos(θ)) ? Thanks

Work done against gravity by Wonder Woman Homework Statement Wonder Woman, whose mass is 52 kg, is holding onto the free end of a 13.0 m rope, the other end of which is fixed to a tree limb above. She is able to get the rope in motion so that she can reach a ledge when the rope makes a 60...
