Atest rocket is launched vertically from ground level (y = 0 m), at time t = 0.0 s. the rocket engine provides constant upward acceleration during the burn phase. at the instant of engine burnout, the rocket has risen to 97 m and acquired a velocity of the rocket continues to rise in unpowered flight, reaches maximum height, and falls back to the ground. what is the upward acceleration of the rocket during the burn phase? 8.0 m/s2 7.3 m/s2 7.5 m/s2 8.2 m/s2 7.8 m/s2

I think the upward acceleration of the rocket during the burn phase is 7.8 m/s2

An  atom  (ours, not carroll's) consists of a positively charged  nucleus, surrounded by one or more negatively charged particles called  electrons. the positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen. although the nucleus is heavy, it is quite small compared with the overall size of an atom. the radius of a typical atom is around 0.1 to 0.25 nanometres (nm), whereas the radius of a nucleus is about 10-6  nm.  *  if an atom were enlarged to the size of the earth, its nucleus would be only 200 feet in diameter and could easily rest inside a small football stadium.read more on -

No it doesnt because it can be any number.
