I believe the answer is B.
Given what we know, we can confirm that as Halley's comet moves closer to the sun, we can expect its potential energy to be near its maximum.
<h3>How do we know this?</h3>
We can conclude that its potential energy will increase as it comes closer to the sun, and will reach its maximum at the closest point to the sun. This is because the potential energy of an object is directly proportional to the force of gravity acting on that object. As Halley's comet approaches the sun, the sun's gravitational pull on the comet is stronger, and thus, its potential energy increases.
Therefore, given the relationship between gravity and potential energy, we can confirm that s Halley's comet moves closer to the sun, we can expect its potential energy to increase and be near its maximum.

Answer:
The solution is given below:
Explanation:
The computation of the speed is shown below
As we know that
Speed = distance ÷ time
where
distance is 2000 km
And, the time is 2.5 hours
SO, the speed is
= 2,000 ÷ 2.5
= 800 km/h
Now the distance would be the same i.e. 2,000 km
but the time is 2 hours
So, the speed is
= 2,000 km ÷ 2 hours
= 1,000 km/hr
The direction should be opposite to the first airplane
By knowing the distance between two objects we can not get enough ideas about the location of these respective objects. It can be easily understood from a simple example.
Let us consider two bodies A and B which are in a two dimensional plane. .Let the co-ordinates of body A is [2,2].
Let us consider two possible co-ordinate pairs [1,0] and [0,1]
Let the body B is at [1,0].
Hence the distance between A and B is
Let the body B is shifted to [0,1] now.
Now the distance between A and B will be
Here we observe that distance in each case is same .But in first case the body B was on +X- axis while in second case the body B was on +Y- axis.
Hence distance between points may be same in different planes, but only the distance can not get enough ideas about the location of the objects.It is the points in specific reference frames gives the ideas about the location of the objects. As position is relative ,hence for complete location of a object,the observer also plays a vital role here.
When the image of a distant object is brought into focus of front of a person's retina, the defect is called: nearsightedness.
