The tau particle is a negatively charged particle similar to the electron, but of much larger mass its mass is 3.18 x 102 kg about 3480 times the mass of the electron and about twice the mass of a proton or neutron. nuclear material is transparent to the tau; thus the tau can orbit around inside a nucleus, under the infuence of attracton of the nuclear charge. suppose the ) tau is in a circular orbit of radius 2.9 x 10-15 m inside a uranium nucleus. treat the nucleus as a sphere of radus 7 4x 10-18 m with charge 92e uniformly distributed throughout its volume find the speed of the orbital motion of the tau note that the charge of the tau is the same as that of the electron select one a 5.88 x 107 m's b. 1.18 x 107 m's c. 2.75 x 10 m/'s d. 5.90 x 10 m/s e. 3.51 x 10 m's

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !

h o h o hope you have a merry christmas!

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
