Answer:
1.8m/s^2
Explanation:
Since the two ropes are going up, their combined force is 105+115=220N. With a gravitational force of 186N, the force of the two ropes pulling up the will be 220-186=34N.
Now we need the mass of the bucket itself in order to find the acceleration of the bucket (remember that F=ma and m is needed to find a). Since gravitational acceleration is 9.8m/s^2 and F=186N, 186/9.8=18.97959184 kg for the mass of the bucket.
Now that we have the mass of the bucket, we can find the acceleration of the bucket. Since F=34N from earlier, 34N/18.97959184kg=1.791397849m/s^2=1.8m/s^2 is the acceleration of the bucket.
Therefore, 1.8m/s^2 is the correct answer.

Answer:
b a model of water temperatures in the oceans
Explanation:
A conceptual model is a means of representing abstract theories, with the aim of helping the audience form mental pictures about the subject being discussed. Most of these models utilize diagrams to help form a better understanding of the subject.
In geothermal explorations, water temperatures can be represented using plane or cross sectional views to demonstrate the varying temperatures of water. This is a useful guidde in the exploration proceess and helps any who read the illustrations to form a better understanding of the process and conditions.
A simple electric has two terminals i.e. negative and positive, And it has a top and a bottom namely Metal Cap and Metal disc.
<h3><u>Description of each part :-</u></h3>
- <u>Metal</u><u> </u><u>cap</u><u>:</u><u>-</u><u> </u><em>The</em><em> </em><em>part</em><em> </em><em>which</em><em> </em><em>is</em><em> </em><em>above</em><em> </em><em>the</em><em> </em><em>positive</em><em> </em><em>terminal</em><em>,</em><em> </em><em>a</em><em> </em><em>cap</em><em> </em><em>of</em><em> </em><em>metal</em><em> </em><em>through</em><em> </em><em>which</em><em> </em><em>the</em><em> </em><em>positively</em><em> </em><em>charged</em><em> </em><em>electrons</em><em> </em><em>are</em><em> </em><em>passed</em><em>.</em>
- <u>Metal</u><u> </u><u>disc</u><u>:</u><u>-</u><u> </u><em>The part which is </em><em>below</em><em> the </em><em>negative</em><em> terminal, a </em><em>disc</em><em> of metal through which the </em><em>negatively</em><em> </em><em>charged</em><em> electrons are passed.</em>
- <u>Positive</u><u> </u><u>terminal</u><u>:</u><u>-</u><u> </u><em>In</em><em> </em><em>a</em><em> </em><em>circuit</em><em> </em><em>the</em><em> </em><em>current</em><em> </em><em>flows</em><em> </em><em>from</em><em> </em><em>positive</em><em> </em><em>terminal</em><em> </em><em>to</em><em> </em><em>negative</em><em> </em><em>terminal</em><em>.</em><em> </em>
- These terminals are also known as cathode and anode.
- Cathode is the other name for positive terminal and anode is the other name for negative terminal.
Answer:
A physical change is a change to the physical—as opposed to chemical—properties of a substance. They are usually reversible. The physical properties of a substance include such characteristics as shape (volume and size), color, texture, flexibility, density, and mass.
