Condensation nuclei are small particles in the atmosphere where water vapor condenses to form cloud droplets, making option A the correct answer. They are essential for cloud formation.
Condensation nuclei refer to small particles typically present in the atmosphere, on which water vapor can condense to form cloud droplets.
This means option A is the correct answer.
These nuclei can be composed of various substances like dust, volcanic ash, sea salt, etc. They are crucial for cloud formation, and without them, water vapor would need to supercool to a very low temperature before it could form droplets.

Answer:
Choice C is correct: The sentence is correct as it is.
Explanation:
Let us go through each of the answer choices one by one.
Choice A: Hurricanes can cause a lot of damage, because of high winds, rain, and storm surge.
This sentence places inappropriate comma in the underlined region (..damage, because..) which interrupts the flow of the sentence. Thus this choice cannot be correct.
Choice B: Hurricanes can cause a lot of damage because, of high winds, rain, and storm surge.
This sentence places inappropriate comma in the underlined (...because, of...) region which interrupts the flow of the sentence. Thus this choice cannot be correct.
Choice C: The sentence is correct as is.
The original sentence uses comma's in the proper places—it uses them to list the causes of hurricane damage—and therefore it does not needs to be modified, and thus this choice is correct.
Answer:
The lens of the eye is a convex lens. The image that it forms on the retina is upside down.
Explanation:
The eye makes an image, but it is upside down, the brain corrects the image and turns it right side up
Answer:
it is an upside-down image but the brain realizes it and corrects it in its orientation so we see it in right direction.

A stone is thrown horizontally at 8.0 m/s from a cliff 78.4 m high. The distance from the base of the cliff does the stone strike the ground is 64 m.
Distance is defined as the entire path traveled by an object in motion, regardless of journey direction. Three sight distances are primarily taken into account in the geometric design of road construction. Things that can be measured in terms of length include the dimensions of a section or a room. Distance is the separation between two things, like two cities or two points. There will never be a negative value for either length or distance.
A projectile is an object that is launched vertically into the air and moves while being pulled by gravity. A horizontally launched object that defies gravity is referred to as a projectile.
Thus, a stone is thrown horizontally at 8.0 m/s from a cliff 78.4 m high. The distance from the base of the cliff does the stone strike the ground is 64 m.

Answer:
Change in gravitational potential energy of the chair is,
Explanation:
It is given that,
Mass of the chair, m = 12 kg
Distance of the second floor from the ground, h = 3.3 m
The position of ground at h = 0
Let is the change in gravitational potential energy of the chair. Initial potential f the chair is equal to 0.
or
So, the change in the gravitational potential energy of the chair is 390 joules.
The change in gravitational potential energy of the chair is +385 J.
The change in gravitational potential energy of the chair can be calculated using the formula ΔPE = mgh, where m is the mass of the chair, g is the acceleration due to gravity, and h is the change in height. In this case, the mass of the chair is 12 kg, the acceleration due to gravity is 9.8 m/s², and the change in height is 3.3 m. Plugging these values into the formula, we get ΔPE = (12 kg)(9.8 m/s²)(3.3 m) = 384.72 J. Therefore, the change in gravitational potential energy of the chair is approximately +385 J.
