Choose two objects from the illustration. Based on the scene, how might these objects be in motion and a reference point at the same time? Please answer Assignment is due in 30 minutes

Answer:the sun and the person

Explanation:

According to special relativity theory, motion is considered as based on the observer's a reference frame (the frame which an observer uses for the description of of the observed phenomenon)

The chosen objects are the trees and the airplane wings

1) The trees are;

In motion when viewed from the Sun

Reference point to the man standing

2) The wings of the airplane are;

In motion compared to the trees as seen by the man standing

Reference point to the passengers in the plane

The reason for the above associations is as follows:

An object is said to be in motion where its location with regards to its surroundings changes with time

An object is said to be a reference point if it is used to determine if another object is in motion

The two chosen objects which are; 1) The trees and 2) The wings of the airplane

The chosen objects in the illustration are in motion and a reference point at the same time as follows:

1) (i)a. The trees in the illustration with regards to (wrt) the view from the Sun is in motion as the Earth is turning around its axis. The tree is moving relative to the Sun as the Earth rotates such that the Sun sets  

b. As seen by the airplane passengers, the trees are also in relative motion compared to the wings of the airplane

(ii) a. The trees are a reference point used by the man to tell that the airplane is moving. With the aid of the tree the man is able to tell that the airplane is flying by

b. The trees are also a reference point used by the airplane to know that its position is changing and therefore is in motion relative to the items on the ground

2) The wings of the airplane is in motion as viewed by the man compared to the trees and the building

(ii) The wings of the airplane is a reference point with regards to the pilot or passengers of the airplane with which he knows that the airplane is in motion

Nicolaus Copernicus was a Polish astronomer who is best known for the theory that the sun is near the center of the universe and that the earth and other planets revolve around it. Copernicus did not believe that the planets were influenced by or revolved due to the sun; instead he believed that the sun was located near the center of the universe and that it was this center which influenced those bodies and caused them to revolve. When this theory was first published, the scientific community did not accept it. Which reason BEST explains the reason for rejection of this theory? A) It was not published until his death. B) It was not understood by scientific world. C) It lacked sufficient evidence and explanation. D) It lacked practical examples in supporting theory.
