Explanation:
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

that represent for gues
Answer:
A), C), and E)
Explanation:
Because i'm built different
Options A and C are the noble gases because their outer shell is complete and they do not react with anyone.
What are noble gases?All seven of the chemical elements that make up Group 18 of the periodic table are considered noble gases. Helium, neon, argon, krypton, xenon, radon, and oganesson are the constituent components (Og). Noble gases are inert, tasteless, odorless, and nonflammable gases. Since it was initially thought that these elements could not link to other atoms, that is, that their atoms could not combine with those of other elements to create chemical compounds, they were typically given the Group 0 designation in the periodic table.
The more suitable name, Group 18, has been given to them as a result of their electrical structures and the discovery that some of them do in fact form compounds.

What can you infer about a wave with a long wavelength?
CHOICES:
- It has a high amplitude
- It has a low amplitude
- It has a high frequency
- It has a low frequency
Answer:
It has a high frequency
Explanation:
A wave is the form of sine wave which has crests and troughs. A wave with a long wavelength has a low frequency.
What is the wavelength?Wavelength is the distance between the adjacent crest or trough.
Wavelength is inversely related to the frequency as
f = v / λ
This shows that longer the wavelength, low will be the frequency.
Thus, a wave with long wavelength infers that is has a low frequency.

prove p = hdg
please give answer if you know
P = Force/Area
= Weight/Area
= Mass × gravitational field strength/Area
= Density × Volume × gravitational field strength/Area
= Density × Area × height × gravitational field strength/Area
P = height × density × gravitational field strength
Hence, P = hdg
The pressure is the force applied on per unit area of an object. It can also be described as the product of height, density, and gravitational field strength.
What is Pressure?Pressure is the force applied perpendicular to the surface area of an object over which that force is applied. Gauge pressure is the pressure that is relative to the ambient pressure on an object. Various units of power are used to express pressure of an object. The SI unit of pressure is Pascal (Pa).
Pressure of an object can be calculated by the formula:
P = Force/Area
P = Weight/Area
P = Mass × gravitational field strength/Area
P = Density × Volume × gravitational field strength/Area
P = Density × Area × height × gravitational field strength/Area
P = height × density × gravitational field strength
Hence, P = h × d × g
Therefore, the pressure of an object can be calculated as the product of height, density, and gravitational field strength.

A diver jumps off of the platform and accelerates towards the water at 9.8 m/s2. The diver has a mass of 54 kg. At what force, will the diver jump into the water?
Answer:
The answer is 529.2 N
Explanation:
The Formula for Force is F=M*A
Force equals mass times acceleration,
The mass is 54kg and you multiply that by the acceleration which is 9.8m/s^2
54*9.8= 529.2N
All you have to do is multiply the two numbers when it comes to finding the force.
