Answer:

The answer is: a column that shows how the dependent variable changes.

Explanation:

An experiment is <em>a process that is carried out by a researcher in order to find out whether his hypothesis is valid.</em> In order to conduct a proper experiment, it is very important to include both the <u>"dependent"</u> and <u>"independent" variables.</u>

A dependent variable refers to <u>the variable that changes in response to the presence of an independent variable.</u> On the contrary, an independent variable is <u>the variable (such as factors) that is being changed in order to control the experiment. </u>

Remember that<em> independent variables do not depend on other factors.</em> Thus, i<u>t is only the dependent variable's change that matters in an experiment.</u>

This is the reason why Dalila needs to have a column that shows the dependent variable changes (and not the independent variable changes).

What are the effects of gravity on earth?​
Sliva [168]

Answer:

Without it, we could not survive on Earth. Earth orbits the sun due to the gravity of the sun, which maintains us at a convenient distance from it to enjoy the sun's warmth and light. It keeps the air we need to breathe and our atmosphere in place. Our planet is held together by gravity.

A ball that is attached to a string travels in a horizontal, circular path, as shown in Figure 1. At time t0 , the ball has a sp
Levart [38]

Answer:

F₁ = 4 F₀

Explanation:

The force applied on the string by the ball attached to it, while in circular motion will be equal to the centripetal force. Therefore, at time t₀, the force on ball F₀ is given as:

F₀ = mv₀²/r   --------------- equation (1)

where,

F₀ = Force on string at t₀

m = mass of ball

v₀ = speed of ball at t₀

r = radius of circular path

Now, at time t₁:

v₁ = 2v₀

F₁ = mv₁²/r

F₁ = m(2v₀)²/r

F₁ = 4 mv₀²/r

using equation (1):

<u>F₁ = 4 F₀</u>
