Explanation:
Radio Telescope:
1. FAST (Five Hundred Meter Aperture Spherical Telescope), China is the largest single dish radio telescope in the world with a dish of diameter 500 meters. Although its construction is over but its not yet functional.
2. Arecibo Observatory, Puerto Rico is the largest single dish <em>operational</em> radio telescope having a single dish of diameter 305 meters..
X - ray Telescope: Chandra X ray observatory also known as Advanced X-ray Astrophysics Facility (AXAF) is the largest x-ray telescope with aperture of 1.2 meters. It can detect X-ray sources which are 100 times fainter in comparison to any previous telescope.
Gamma ray telescope: Fermi Gamma ray telescope is the largest gamma ray telescope.

In order for a system to be in equilibrium , two conditions must be met. Net force must be 0.
Answer:
Only 3 is true: The truck exerts the same amount of force on the car as the car exerts on the truck.
Explanation:
Compare the forces if the light truck is standing still when the car hits it.
1. The car exerts a greater amount of force on the truck than the truck exerts on the car. FALSE. This violates Newton 3rd Law of Action-Reaction.
2. The truck exerts a greater amount of force on the car than the car exerts on the truck. FALSE. This violates Newton 3rd Law of Action-Reaction.
3. The truck exerts the same amount of force on the car as the car exerts on the truck. TRUE. This is Newton 3rd Law of Action-Reaction. When there is a contact between objects, both exert on the other an equal and opposite force.
4. None of the answers correctly describes the situation. FALSE. 4 is true.
5. Neither exerts a force on the other. FALSE. If the car hits it then forces must come into play.
