Answer:
is the density of the substance which has 5gm and in an area of 12cm, 10cm and 2cm.
<u>Explanation:</u>
To find the density of a substance, we know that density is the ratio of mass of the substance and volume of the substance. Hence, given that mass of the substance is 5gm and volume of the substance is 12cm×10cm×2cm =240
Therefore, we came to know that density of the substance which has mass and volume can be found by using the above formula. <em> </em>is the density of the substance whose <em>mass is 5gm and volume is 240 .</em>
Answer:
The pressure reduces to 2.588 bars.
Explanation:
According to Bernoulli's theorem for ideal flow we have
Since the losses are neglected thus applying this theorm between upper and lower porion we have
Now by continuity equation we have
Applying the values in the Bernoulli's equation we get
Incomplete question. The options read;
A. Tech A
B. Tech B
C. Both A and B
D. Neither A nor B.
Answer:
<u>C. Both A and B</u>
Explanation:
Technician B is correct because the technician highlighted valid reasons why draining the compressed air systems is important.
For example, since this system helps to absorb moisture or oil from storage areas they thus need to be drained periodically in other to allow for more absorption space.
Also, the reasons mentioned by Technician A are of course correct because it is generally believed that the application of lubricants such as oil helps to reduce wear and tear.
