What is the minimum total energy released when
an electron and its antiparticle (positron)
annihilate each other?
(1) 1.64 × 10^–13 j (3) 5.47 × 10^–22 j
(2) 8.20 × 10^–14 j (4) 2.73 × 10^–22 j

Explanation:

Energy released in this process is given by

here we have

since here mass of two electrons converted into energy so we have

so here energy released is the energy of rest mass energy due to two charges i.e. electrons and positrons

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.
