Answer: The correct answer is Image 2.
Explanation:
Concave lens is defined as the lens which diverges the light falling on it. It is considered as a diverging lens.
Convex lens is defined as the lens which converges the light falling on it. It is considered as a converging lens.
Types of concave lens:
Types of convex lens:
So, image 1 is a double convex lens, image 2 is a plano-concave lens, image 3 is a plano-convex lens and image 4 is a concavo-convex lens.
Hence, the correct answer is Image 2.

C: "The students pass the envelope from one student to the next until it travels across the room."
To quote ck12, "The particles of the medium just vibrate in place. As they vibrate, they pass the energy of the disturbance to the particles next to them, which pass the energy to the particles next to them, and so on."
Possible answers:
oceans/seas/lakes/rivers
atmosphere/sky
Explanation:
Most of the air's moisture evaporates from rivers, lakes, seas, and oceans. Water at the surface of the Earth evaporates into water vapor, which rises into the sky and forms clouds, which eventually release water back onto Earth as precipitation.
Answer:
0.0166 m/s
Explanation:
time taken, t = 10 min = 10 x 60 = 600 second
distance, d = 10 m
Speed of an object is defined as the ratio of distance traveled to the time taken by the object.
Speed = distance / time
its SI unit is m/s and it is a scalar quantity.
So, the speed is given by
