In Niels Bohr's 1913 model of the atom, the electron is in a circular orbit around a nucleus. An electron is 7.60 10-11 m from a nucleus traveling in a circular orbit with a speed of 2.45 106 m/s. (a) What is the magnitude of the magnetic moment due to the electron's motion?

14.896 x 10^-24

Explanation:

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
