Aproton and a neutron of masses (given in data) are confin deep square-well potential with l- 10 femto meters a ve ) sketch a diagram to show the allowed energy levels of the both particles inside the well. (ii) estimate their ground-state energies of each. fii) define briefly and provide examples of nuclear reactions known as fission" and "fusion". what makes those reactions plausible?

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.

conservation of mass

mass before something happens = mass afterwards

the answer is c. the lower legs are levers, and the knees are fulcrums. the ankles hold the loads.
