Answer:

4.) At room temperature, it changes directly from a solid to a gas a process called sublimation. This expansion causes a rapid temperature drop, and some of the carbon dioxide freezes into solid pellets of dry ice.

5.) Balsa wood combines the two elements necessary to a successful flight: strength and lightness. Balsa wood is also easy to cut and carve with just a good, sharp hobby knife or razor saw, so no need for heavy power tools. Or any lighter wood.

6.) Density is mass/volume. So: D=10.7/5

D=2.17g/cm^3

Answer:c will be answer

Explanation:Because u know F=ma so if we wanna know m then we should move a on left side and it will be in divide with f after moving on left side so

M=F/A

2 kids are running down the hall at 2 m/s, one is 40kg and the other is 50kg (p=ma)

Georgia [21]

The net force acting on the two (2) kids is equal to 180 Newton.

<u>Given the following data:</u>

Mass of kid 1 = 40 kilogram.

Mass of kid 2 = 50 kilogram.

Acceleration = 2 $m/s^2$

To determine the net force acting on the two (2) kids:

First of all, we would calculate the total mass of the two (2) kids:

$Total\;mass = 50+40$

Total mass = 90 kg.

<h3>How to calculate net force.</h3>

In this exercise, you're required to calculate the magnitude of the net force that is acting on these two (2) kids running down the hall. Thus, we would apply Newton's Second Law of Motion.

Mathematically, Newton's Second Law of Motion is given by this formula;

$Net\;force = mass \times acceleration$
