sir my ques. is In annihilation concept of chp. electrostatics why e- + e+ -> 2gamma ray photon,
The question is not fully clear. If your question is Why TWO gamma rays, I would recommend to go through the following link Click Here for More information
Further, I request you to post detailed questions and doubts here.
Thank you

sir when we climb up a rope with acceleration how do tension helps in that please explain
Use Newton’s laws of motion and free body diagrams. When we are at rest or moving up or down without acceleration, our weight will be equal to T.
But when moving with acceleration, it will be different. While climbing up with acceleration, ma = T-mg
or T = m(a+g)
when we climb up then rope is very tight because of our weight. then tension is greater than weight so climb. there ma=T-mg (because tension is greater)you right admin
yes; T= m(a+g) while climbing up

specific resistance of copper wire is 1.6 into 10 rest to the power -8 ohm.m. What happens to its specific resistance and resistance if one meter long wire is cut in to two pieces??
plz answer it.
