Answer: A Brightfield microscope equipped with an opaque light stop is able to block light from the illuminator and creating bright objects on a dark background.
Explanation: To find the correct statement about Brightfield microscope, we need to know more about the Brightfield microscope.
<h3>what is Brightfield microscope?</h3>
- The Brightfield microscopic technique is generally used with the compound microscopes and, these are one, among the widely used optical illumination techniques.
- The Brightfield microscope or Compound light microscope is an optical instrument, which uses light rays and produces dark images with a bright background.
<h3>
How Bright field microscope works?</h3>
- A brightfield microscope equipped with a opaque light stop, will produce bright objects on a dark background by blocking the light illuminated from the light source.
- This opaque light stop, blocks the light rays that arising from the illuminator to the objective lenses and, only allows the reflected or transmitted light of the specimen. As a result, we get bright objects with a dark background.
Thus, we can conclude that, A Brightfield microscope equipped with an opaque light stop is able to block light from the illuminator and creating bright objects on a dark background.

Whenever we represent forces using vectors, we ensure that the vector begins at the point of force exertion. In the case of weight, the point of exertion of the force is known as the center of gravity, which is the point through which the weight of an object can be said to act. Therefore, the downward arrow representing the weight would begin at the center of gravity of the object.
Answer:
The charge carried by the droplet is 
Explanation:
Given that,
Distance =8.4 cm
Time = 0.250 s
Suppose tiny droplets of oil acquire a small negative charge while dropping through a vacuum in an experiment. An electric field of magnitude 
points straight down and if the mass of the droplet is 
We need to calculate the acceleration
Using equation of motion
Put the value into the formula
We need to calculate the charge carried by the droplet
Using formula of electric filed
Put the value into the formula
Hence, The charge carried by the droplet is
No. The companion is wrong.
You are shivering because, since it's cold outside, your body is becoming incapable of maintaining the the same temperature outside ad well as inside.
So, in order to compensate, your body uses mechanism of shivering in order to produce more heat by constricting the blood flow in vessels.
Therefore, you shiver from cold.
