Answer:
1.glasses
2.magnififying glass
3.:??
Explanation:
Camera, eyepiece lens, telescope, and binocular are the matched optical instruments accordingly.
A camera is one in which light passes through the lens and forms a smaller image on the sensor or film that records the image. An eyepiece lens is one in which light passes from an object to an objective lens. This image from the eyepiece lens is an enlarged view of the object.
A telescope is one where light passes through multiple convex lenses to enlarge the image of objects, such as distant stars, that are only small looking because they are so far away.
A binocular is in which light passes through a convex lens creating an enlarged image. This image which starts out upside down from the binocular passes through two prisms to be rotated right-side-up, before passing through the eyepiece lens for further magnification.

Answer:
As it states that "to every action,there is equal and opposite reaction". similarly,when a dolphin swim it pushes the water in the backwards direction as an action The water pushes the dolphin in the forward direction.Thus the dolphin can move through water.

Energy that comes from the sun—solar energy—is clean. It does not cause pollution the way energy from fossil fuels (like gas and oil) does. However, solar energy must be collected before it can be used. The instruments used to collect solar energy are quite costly.
This paragraph states that solar energy ________.
A) causes a lot of pollution
B) is expensive to collect
C) is one kind of fossil fuel
D) is a cheap way to get energy
