Explanation:
Neptune planet has the coldest surface temperature
<u>Explanation:</u>
With temperatures falling to -218°C in Neptune’s upper atmosphere, the planet is one of the coolest in our Solar System. Neptune is the most faraway planet from the sun. Astronomers have speculated that Neptune's huge internal temperature and the transfer of heat between the core and outer layers might be the cause why Neptune isn't significantly more chill than Uranus.
Pressures in this area range between 1 and 5 bars and the temperature reaches a high of 72 K. At this temperature, states are becoming for methane to condense, and clouds of ammonia and hydrogen sulfide are thought to form. At its core, Neptune reaches temperatures of up to 7273 K which is equivalent to the surface of the sun.

Answer:
16 waves
Explanation:
This is actually pretty easy to understand.
First we have the frequency "f" of the waves which is 0.571429 Hz and we want to know how many waves will hit the beach in 28 s. To know this, we need to know the period time of the waves, this can be calculated with the frequency and the following expression:
T = 1/f
With this expression we can calculate the period time of the waves. So replacing the data:
T = 1 / 0.571429
T = 1.749999 s
Now that we have the period, this number means that every 1.75 s, a wave hit the beach. Now to know the number of waves in 28 s, we just divide the period with the given time:
n = t/T
Replacing we have:
n = 28 / 1.749999
<h2>
n = 16 waves</h2><h2>
This is the number of waves that hit the beach in 28 s.</h2>
