B.describes what occurs every time in a situation
Answer:
See the answer below
Explanation:
<em>The best thing one can do in this case would be to return the microscope's objective to low power and then </em><em>re-center the specimen </em><em>before switching back to high-dry power.</em>
Most of the time, <u>what makes the specimen under the microscope to be out of focus at higher objective powers after being in focus at low power is because they are not properly centered on the stage</u>. Hence, before calling on the instructor, it would be wise to first return to low power, re-center the specimen and bring it into focus after which the high power objective can be returned to and the fine focus adjusted to bring the image back to focus.
After doing the above and the specimen still does not come into focus, then the instructor can be called upon.
Answer:
<em>I</em><em> </em><em>hope</em><em> </em><em>this</em><em> </em><em>helps</em><em>. </em>
Explanation:
Vs/Vp = Ns/Np
Vs/9 = 30/300
Vs/9 = 1/10
Vs= 9/10 = 0.9 volts
It is a Step down transformer. This is because the number of turns on the primary coil is greater than that on the secondary coil.
<h2>Option 1 is correct option .</h2>
Explanation:
The velocity of sound depends upon temperature . The temperature is different at different altitudes .
The velocity of sound has no effect of pressure . Thus at different altitudes , if pressure is different , it makes no difference .
Therefore the speed of sound varies rapidly with altitude , due to variation of temperature .
It also depends on the nature of medium . which also varies with altitude .
Moreover we cannot get distance by dividing time interval with 3 .
