a) Experimentally the study of p-p scattering is capable of much higher accuracy than n-p scattering, why?
b) What are the similarities between (nn) & (pp) forces?
a train is starting from rest picks ups a speed of 20m/sec in 200secs it continoues to move at the same speed for next 500 secs it is brought to rest in next 100 secs. plot speed time graph and calculate the uniform accelration and retardation
two charges of equal magnitudes and at a distance r exert a force F on each other.if the charges are halved and distance b/w them is doubled then new force acting on each other is:-
1.F/8
2.F/4
3.4*F
4.F/16
Explain why even though the reaction has taken place, the product element is the same as the reactant element in uranium 238 and the reaction forms uranium 239. Please help.
