1. a floating object moves up and down 15 times in 60. seconds because of ocean waves. calculate the period of the ocean waves. Period (T) = total time /#oscillations counted

*60/15 = 4 T

2. calculate the frequency of the ocean waves. show your calculations and include units in your answer.

3. an additional wave property must be known in order to calculate the velocity of the ocean waves. identify the additional property.

period

frequency

wavelength

speed

4. describe what will happen to the object if the amplitude of the ocean waves increases and all other wave characteristics stay the same.

plz help, i think i have #1 correct but i need help with the rest, just trying to graduate.. will give brainliest

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 -

Honestly "global warming" may be a slight possiblity, however they called it "climate change" because its not real, in fact we had one of our coldest days here not too long ago, and the "issues" with this subject is a blindfold for actual problems.
