Question 1 - A hand span

Question 2 - B loaf of bread and a pillow

Question 3 - B He should repeat the test with three additional batteries of varying voltages to demonstrate the reproducibility of results.

These questions are all about materials all materials are matter the first question I pick A because a hand span would be a good measuring tool when you are measuring wings like that the second question I pick B because density is how light a object is the third question I pick B because when you repeat the expierment you are adding in the results and making your solution stronger.

Your answers are A,B,and B.

Naddika [18.5K]

Answer:

The scientific questions here are:

<em>a) How will climate change affect forests</em>

<em>b) How did life on Earth begin</em>

<em>c) Why did dinosaurs go extinct</em>

Explanation:

Scientific question are logical quantifiable questions, whose answers can be measured. A good scientific question must have answers that can be tested by a carefully designed experiment or measurement. Some qualities like "prettiest" and "amazing" cannot be tested for nor are they measurable, and hence, they do not make a testable component of good scientific question.

Proved that<br>V = u+at<br>​
kondaur [170]

Answer:

\sf Proof \ below

Explanation:

We know that acceleration is change in velocity over time.

\sf a=\frac{\triangle v}{t}

\sf a=\frac{v-u}{t}

v is the final velocity and u is the initial velocity.

Solve for v.

Multiply both sides by t.

\sf at=v-u

Add u to both sides.

\sf at + u=v
