Answer:

3 g/cm^3

Explanation:

Density can be determined by mass divided by volume, or P=m/V.

This would be 47.4 grams (mass) / 15.8 cubic centimeters (volume). The units are grams per cubic centimeter, noted as g/cm^3.

Density = mass over volume
so
47.4g/15.8cm^3
=3g/cm^3

The men's world record for swimming 1500 m in a long course pool is 14 min 34.56 s. At this rate how many seconds would it take
vlabodo [156]
Distance = 1500m, time = 14min 34.56s = 14*60 + 34.56 = 874.56s

Speed = Distance / time = 1500/874.56 = 1.715 m/s

In order to swim 0.7 miles, 1 mile = 1609.344 m

Time = Distance / speed = 1609.344 m / 1.715 m/s = 938.393 seconds

938/60 = 15 minutes, 38 seconds.

= 15 minutes 38.393 seconds.

Which of these planets has the coldest surface temperature?
lianna [129]

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.
