It has been said that the energy-time version of the uncertainty principle allows a violation of the conservation of energy. The argument is that the uncertainty AE allows the possibility that we may not know that energy conservation is violated during a small time At. Discuss arguments pro and con concerning this possibility.

Can you explain uncetiany and sig figues to me. Why would 30 with +- 0.1 uncertainity have have two sig figs. My question is how does uncertian relate to the number of sig figs.

To measure the muon magnetic moment a 2.9-T uniform magnetic field is used. How much energy is stored in the field if the experimental chamber where the field is created has dimensions of 65 cm×35 cm×60 cm?   The energy, ? How long will it take to “switch on” the field if the experiment uses a 1.5-kW power supply? Time ?

Good day, could you help me demonstrate the following?Subject: Relativistic Physics.Thanks in advance. Prove that the photon, a massless particle, has momentum.

With proper explanation both plz ... Vll upvote.....

Pleaseneed solution for no: (b) and (c)
