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.

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
Answers
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

In a Compton scattering experiment, scattered photon is found to have its wavelength three times of the incident photon for the scattering angle of 180°. Calculate Wavelengths (in nm) of the incident, scattered photon, and Compton shift.
Answers
Answer:
Two of Einstein’s influential ideas introduced in 1905 were the theory of special relativity and the concept of a light quantum, which we now call a photon. Beyond 1905, Einstein went further to suggest that freely propagating electromagnetic waves consisted of photons that are particles of light in the same sense that electrons or other massive particles are particles of matter. A beam of monochromatic light of wavelength \lambda (or equivalently, of frequency f) can be seen either as a classical wave or as a collection of photons that travel in a vacuum with one speed, c (the speed of light), and all carrying the same energy, {E}_{f}=hf. This idea proved useful for explaining the interactions of light with particles of matter.

When the rudder moves to the left the plane will move to the right or left?
Answers
To turn the aircraft, the pilot uses all three flight controls. The rudder is controlled in the cockpit by foot pedals. When the pilot presses the left pedal, the rudder deflects to the left. This deflection creates more lifting force on the right-hand side of the rudder, which moves the plane's nose to the left.
Answer:
The rudder will move to the right
Explanation:
This is using opposite forces and aircraft speeds to identify the modules used to make the rudder move the plane. If the rudder moves right, the plane goes left. If the rudder goes left, the plane goes right.

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
Answers
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.
