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.
If the atmosphere were 50% more dense, sunlight would be much redder then it is now. As the atmosphere increase in density, more and more of the blue light would be scattered away in all directions, making the light that reaches the ground very red. Think of the color of a deep red sunset, but this would be the color even at noon.
Hope this helps!
Answer:
Yes Newton's laws apply to small objects
EX: Newton s first law
when body at rest always want to be at rest
or body at motion always want to be at motion
unles an external force acts upon it
for example a eraser on the table will be at rest
if so e apply some force then it comes motion
so, Newton s law apply to small object s
Answer:
Car C
Explanation:
It is given that,
Five race cars speed toward the finish line at the Jasper County Speedway. The mass of each car has same mass. The speed of all cars are given as :
Car A = 890 m/s
car B = 850 m/s
Car C = 790 m/s
Car D = 895 m/s
Car E = 870 m/s
The distance is constant because the finish line is same for all cars. The speed of an object is given by the total distance covered divided by total time taken i.e.
Where
d = distance
t = time required by the car to come to a full stop
So, time taken is inversely proportional to the speed of the car. The car having less speed will take maximum time to come to stop. Hence, car C will require longest time to come to a full stop.
