Answer:
I think the answer will be water ,sorry if ik wrong
The answer to the question will be X i.e the image will be produced at X.
EXPLANATION:
As per the diagram given in the question, the image will be formed due to a plano-concave lens. It is so because the lens is thicker at edge than in the centre and flat on one side.
The source of light is a bulb. The object is present between W and X.
The light rays are appeared to be diverged after being refracted through the lens. So, the lens can not produce any real image.
The rays are appeared to be coming from X when they are produced back, and produces a virtual image at this point. The nature of image will be virtual, erect and diminished.
Hence, the image will be produced at X.
a. Earth's orbit would not change.
Explanation:
The force that keeps the Earth in circular motion around the Sun is the gravitational force between the Earth and the Sun, whose magnitude is given by:
where
is the gravitational constant
m is the mass of the Earth
M is the mass of the Sun
r is the distance between them
From the equation, we observe that this force depends only on three factors:
- the mass of the Earth
- the mass of the Sun
- their separation
If the Sun is replaced by a black hole of the same mass, none of these factors would change (the central mass M would remain the same), therefore the gravitational force F would not change, and therefore the orbit of the Earth would not change.

hope it fun!
Answer:
Cold Front 3 // Stationary Front 1 // Warm Front 2 // Occluded Front 4
Explanation:
It's simple. Warm front means the warm air is pressing forward, which is why it's a warm front. Stationary Front, meaning they're at a standstill, also makes sense because stationary means not moving. Then since your last option is Occluded Front, since the others already have an answer, you have no choice but to match 4 with it. I took the quiz and got the answer right. :D
