Answer:
Simple machine
Explanation:
It is a simple machine because the person wants to raise the load by an inclined plane. Simple machines perform work with the mechanical advantage offered by the machine itself, such as using a bar as Lever, lifting a load by means of a pulley. simple machines multiply or change direction a force. While Composite machines are the Union of several simple machines that perform a given job, examples of combined machines are found on bicycles, a washing machine, a car, and others.
Answer:
C.
The Earth and Moon both exert a gravitational force on each other.
Explanation: just did it booom
Answer:
the principle of original horizontality and the principle of superposition
Explanation:
The <em>principle of horizontality</em> states that layers of sediment are originally deposited horizontally under the influence of gravity.
The <em>principle of superposition</em> states that the oldest layer layer is at the bottom and each layer above it is younger, with the youngest being at the top.
Unconformities help us find the age of different layers. An unconformity is a surface in which no new solid matter is deposited after a long geologic interval. <em>Angular unconformity </em>is a type of unconformity which different kinds of stratum were tilted or folded before deposition of younger layers of solid matter above the unconformity. Once the layers were folded and tilted, the older layers of the solid matter eroded, then the younger layers were deposited on the older layers. There <em>angular unconformity </em>is the contact between young and old layers of solid matter.
Therefore, these two principles therefore describe how the tilted layers are older than horizontal layers.
Answer:
Far point of the eye is 22.24 m
Far point of the eye is 0.4 m
Explanation:

Object distance = u
Image distance = v
Lens equation

Far point

Far point of the eye is 22.24 m
Object distance = u = 0.25-0.02 = 0.23 m


Near point

Far point of the eye is 0.4 m
Answer:
Red light
Explanation:
The electromagnetic spectrum classifies all the electromagnetic waves according to their wavelength/frequency. In order from shortest to longest wavelength, we have
Gamma rays
X rays
Ultraviolet
Visible light
Infrared
Microwaves
Radio waves
All of these waves are invisible to human eye, except for the "visible light" part of the spectrum. Waves in the visible light part are perceived by human as different colors, depending on their wavelength. More specifically, they appear as follows:
Violet (380-450 nm)
Blue (450-495 nm)
Green (495-570 nm)
Yellow (570-590 nm)
Orange (590-620 nm)
Red (620-750 nm)
So we see that the longest electromagnetic wave in the visible light part of the spectrum corresponds to red light.
