How does the displacement moved affect the amount of work done?
Sholpan [36]

The displacement affect the amount of work done by the fact that more displacement implies more work.

Option B

<u>Explanation:</u>

Work can be defined as the "measure of energy transfer" that occurs when an object is moved over a distance by an external force which is applied in the "direction of the displacement".

Work can be formulated as,

W = (F \times s)\  N / m \\ \\Work = ( Force \times Displacement )\   Newton/meter

From the above-mentioned formula, we can infer that Work is directly proportional to the displacement of the object.Therefore, more the work is more will be its displacement.

What is the density of a sample of a substance with a volume of 120ml<br> and a mass of 90g?
tigry1 [53]

Answer:

<h3>The answer is 0.75 g/mL</h3>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}  \\

From the question

mass = 90 g

volume = 120 mL

We have

density =  \frac{90}{120}  =  \frac{9}{12}  =  \frac{3}{4}  \\

We have the final answer as

<h3>0.75 g/mL</h3>

Hope this helps you

My teacher is grading this soon can someone help me ASAP!
Stolb23 [73]

10. You demonstrated the difference in density of the two objects. It is a physical property.

11. First calculate the density for all of them: density = mass/volume

Density:

A. 5/6 g/ml

B. 10/9 g/ml

C. 15/16 g/ml

D. 20/10 g/ml

If the density of the substance is higher than the density of the substance it is put in, then it will sink. So substances B and D will sink in water, as their densities are higher than 1 g/ml.

12. Ammonia weighs less than water does-- for example, the weight of 8 gallons of ammonia will be equivalent to the weight of 5 gallons of water.

Hope this helped!
