Answer:

\frac{2}{5}

Explanation:

Probability refers to chances of occurrence of any event.

Value of probability is greater than or equal to 0 and less than or equal to 1.

Probability = Number of favorable outcomes ÷ Total number of outcomes

Total number of students in math group = 5

Also, 2 students are randomly picked to  be the co-captains.

Probability that students were Sammie and Victor = \frac{2}{5}

Develop a demonstration to show how weight is not the same thing as mass
maksim [4K]

Answer with Explanation:

"Mass" and "weight" should never be used interchangeably with each other. Mass refers to the <u>total amount of matter</u><u> that can be measured in an object, </u>while weight refers to the<u> measure of the</u><u> force of gravity</u><u> that is acting on the object's mass.</u>

The mass of an object is<u> constant</u> (meaning, it doesn't change even if the object will be placed on another location) while the weight of an object relies on the <em>force of gravity.</em> So, this means that your mass on Earth and on the moon are identical, however, your weight on Earth and on the Moon are different. You will weigh lesser on the Moon because it has a lesser surface gravity than that of Earth.

So, this explains the answer.

Calculate the pressure exerted by an book of mass 20kg occupying an area of 2 m square.​
kotykmax [81]

The answer is 100 Pa.

The formula for calculating pressure is :

<u>Pressure = Force ÷ Area</u>

<u />

We are given that :

  • mass = 20 kg
  • area = 2 m²

We also know that :

<u>Force = mass ×g</u>

<u />

So, force will be :

  • F = 20 × 10
  • F = 200 N

Now, we can finally calculate pressure :

  • P = 200 ÷ 2
  • P = 100 Pa
