Answer:

3 grams per cubic centimeter.

Explanation:

density = mass ÷ volume.

d = m ÷ v.

m=81 g.

volume = length × width × height.

volume = 3 cm × 3 cm × 3 cm = 27 cubic centimeters.

v = 27 cubic centimeters.

d = 81 ÷ 27

density = 3 grams per cubic centimeter.

How can you use your empty jet pack to get you back to the station
Vanyuwa [196]
Swing it backwards and forwards, because according to newtons law, every action force has an opposite and equal reaction force.  When you swing it one way, the jet pack will be pushed to other way, so when this motion is completed as many times/ with enough energy, the person will reach the station

Please help! this is due today! No links please and full paragraph form answer! Will give you brainliest!
leonid [27]

Answer:

1. Hailstones are formed when raindrops are carried upward by thunderstorm updrafts into extremely cold areas of the atmosphere and freeze. Hailstones then grow by colliding with liquid water drops that freeze onto the hailstone's surface.

2. It's slightly complicated to me because you have to take into consideration the change in pressure as well as the geometric growth of the volume of a sphere as you increase the radius.

3. When you are measuring the air temperature, be sure to have the thermometer in the shade. If the sun shines on the thermometer, it heats the liquid. Then the reading is higher than the true air temperature. Also, when you take the thermometer outside, give it enough time to adjust to the outdoor air temperature. That might take several minutes.

Hope that helps (:
