<u>Answer</u>

4.volatile

<u>Explanation</u>

Volatile substances are substances that are can evaporate easily. The chemical definition of volatile substance is one that can boil at low temperatures and change from liquid to gas easily.

From choices given in the question, the correct answer is 4.volatile

<span>The answer to this question is that non metals are volatile. Volatile means evaporating easily. Non metals have the characteristics and properties of being brittle and poor conductors of heat and electricity. Non metals are also good oxidizing agents and physically they may be in liquid, solid or gas state. Examples of non metals are carbon, sulfur, argon, neon, and hydrogen.</span>

For this experiment on a solar collector, the variables include the following:

  • Time
  • Temperature
  • Plastic wrap
  • Black plastic

<h3>What are the variables?</h3>

In Science, a variable can be defined as a measurable attribute or physical quantity that changes or varies across an experiment and as such can take on different numerical values.

For this experiment on a solar collector, there are different variables and these include the following:

  • Time
  • Temperature
  • Plastic wrap
  • Black plastic

Furthermore, you should determine both the greatest and smallest rate of temperature change for each of the trials by subtracting the initial temperature from the final temperature based on the numerical values obtained from this experiment.

In conclusion, the trial with the greatest numerical value has the greatest rate of temperature change while the trial with the smallest numerical value has the smallest rate of temperature change

An ant crawls along a sidewalk with a velocity of 0.1 m/s in a direction that is 45 degrees relative to the edge of sidewalk. If
alekssr [168]
First draw a diagram (see attached picture).

We know the any traveled 1 m away from the sidewalk, and since we have a 45-45-90 triangle we know that the horizontal distance traveled is also 1 m. Use a^2+ b^2 = c^2 to find the distance the ant traveled. We get sqrt(2).

V=displacement/time
So 0.1 = sqrt(2) / t
Solve for the to get sqrt(2)/0.1 = 14.14 seconds.

A man walks 40 m North, then 70 m East and then 40
Anastasy [175]

Answer:

Displacement = 70 m towards east

Explanation:

Displacement is the shortest distance between the two points.

Let us say that he starts at the point O and travels in a path ABC.

If we join the initial and final point of the path travelled by him, it will give the displacement of the man.

Distance from O to A = 40 m

Distance from A to B = 70 m

Distance from B to C = 40 m

Distance from O to A = Distance from B to C

We want the displacement which is distance between the points O and C

In rectangle opposite sides are equal. Hence Distance from O to C = Distance from A to B

Displacement = Distance from A to B

Hope it helps,

Please mark me as the brainliest.

Thank you
