Answer:
khoảng cách = 8km / h
Explanation:
khoảng cách = tốc độ / thời gian
khoảng cách = 12/40
khoảng cách = 8km / h
B you wold go from the crust all the way to the inner core
The specimen that will be on display is set up on stage. When working at greater magnifications when careful motions of the specimen slide are needed, a mechanical stage is employed.
<h3>What is a compound light microscope?</h3>
A microscope having several lenses and a separate light source is called a compound light microscope.
Ocular lenses are located in the binocular eyepieces of this type of microscope, while objective lenses are located in a rotating nosepiece that is located closer to the specimen.
Hence, the part of the compound light microscope is specimens placed for viewing is stage.

Answer:
Size of image: 1.8 cm inverted
Magnification of camera: -0.1
Explanation:
Given:
= size of bird = 18 cm
= distance of the bird from the camera = 2 m = 200 cm
= distance of the film from the camera = 20 cm
Assume:
= magnification of the camera
= size of image of the bird
Using sign convention, we have

The hole in the pinhole camera behaves as a convex lens. The other face opposite to the hole face behaves like a film where the image is formed to be seen. So, using the formula of magnification, we have

This means the image of the bird measures 1.8 cm in length where negative sign in the calculation represents that the image formed is inverted.
Hence, the image of the bird on the film is 1.8 cm large.
Now, again using the formula of magnification, we have

Hence, the magnification of the camera is -0.1.
