Answer: What is the acceleration of an object that moves at constant velocity? Acceleration is Zero
What is the net force on the object in this case? The ner force is also Zero
Explanation: If the velocity is constant means that the acceleration is zero, from Newton second law is clear that net force is also zero
Fnet= m* a as v is constant a=0 this Fnet is zero.
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.
