Let's say you are on the third story of an apartment building that has a swimming pool. for some insane reason you think it is a good idea to jump off your balcony into the swimming pool. if you are a height h above the ground and a distance r from the pool how far must you be running in terms of h and r to make into the pool and not end up as cement pizza? are there any applications of this?

Estimate the kinetic energy of mars with respect to the sun as the sum of two terms, that due to its daily rotation about its axis, and that due to its yearly revolution about the sun. (assume mars is a uniform sphere with mass = 6.4Γ10 to the power of 23 kg, radius = 3.4Γ10 to the power of 6 m, rotation period = 24.7 hours, orbital period = 686 days and is 2.3Γ10 to the power of 8 km from the sun.)

Neutrons are placed in a magnetic field with magnitude 2.30 t. part a part complete what is the energy difference between the states with the nuclear spin angular momentum components parallel and antiparallel to the field? Ξ΄e Ξ΄ e = 2.77Γ10β7 ev previous answers correct part b part complete which state is lower in energy: the one with its spin component parallel to the field or the one with its spin component antiparallel to the field? which state is lower in energy: the one with its spin component parallel to the field or the one with its spin component antiparallel to the field? parallel antiparallel previous answers correct part c part complete how do your results compare with the energy states for a proton in the same field (Ξ΄e=4.05Γ10β7ev)? how do your results compare with the energy states for a proton in the same field this result is smaller than but comparable to that found in the example for protons. this result is greater than but comparable to that found in the example for protons. previous answers correct part d the neutrons can make transitions from one of these states to the other by emitting or absorbing a photon with energy equal to the energy difference of the two states. find the frequency of such a photon. f f = mhz previous answersrequest answer incorrect; try again; 5 attempts remaining
