The speed of light in air is 3 x 108 m/s. The speed of light in ice is 2.29 x 108 m/s. What is the refractive index from air to ice?
Answer:
η = 1.31
Explanation:
The formula for the refractive index of from air to some other medium is given by the following formula:
[tex]\eta = \frac{c}{v}\\[/tex]
where,
η = refractive index = ?
c = speed of light in air = 3 x 10⁸ m/s
v = speed of light in ice = 2.29 x 10⁸ m/s
Therefore, using these values in the equation we get:
[tex]\eta = \frac{3\ x\ 10^8\ m/s}{2.29\ x\ 10^8\ m/s} \\[/tex]
η = 1.31

Answer:
Laterite is your correct answer
Explanation:
Well i took the quiz and made a %100 meaning i am correct.
The laterite soil is found in warm, humid climates
What are Laterite soil?A variety of rocks weathered under highly oxidising and leaching circumstances to form laterite soil, which is present in the soil layer and is rich in iron oxide.
Given data ,
Let the soil be represented as A
Now , the soil is found in warm, humid climates
The laterite soil is is rich in iron and aluminium, are assumed to have developed in hot, humid tropical climes. Because to the substantial concentration of iron oxide, nearly all laterites have a rusty-red colour.
They develop as a result of prolonged, intensive erosion of the underlying rock material, which most frequently takes place during periods of high temperatures and heavy precipitation that alternate with periods of dry weather.
Hence , Laterite is the type of soil is found in warm, humid climates.

Two astronauts (each with mass 70 kg) push off each other in space. One astronaut carries 46.7 kg of equipment and moves away with a speed of 0.3 m/s.
Calculate the velocity of the other astronaut.
Answer:
Kindly, Refer to the attachment...A 1,500 kg car is at rest on a level track. The driver gives the engine gas and the car begins to accelerate forward. The car moves from 0 m/s to 27 m/s in 8 sec. What is the acceleration of the car?
Answer:
3.375 m/s²
Explanation:
Using equation of motion:
v = u + at
Here, v = 27m/s & u = 0m/s & t = 8 sec
Let the acceleration be a.
=> 27 = 0 + 8(a)
=> 27/8 = a
=> 3.375 m/s²

A rectangular container of base 50 cm by 30 cm is filled with water to a depth of 5 cm. How much is the pressure exerted at the base? (Take p= 1000 kg/m3 and g=10m/s)
Answer:
the pressure exerted at the base of the container is 490 N/m²
Explanation:
Given;
density of water, ρ = 1,000 kg/m³
base of the rectangular container, = 50 cm by 30 cm
height of water in the tank, h = 5 cm = 0.05 m
The pressure exerted at the base of the container is calculated as;
P = ρgh
where;
g is acceleration due to gravity = 9.8 m/s²
P = 1000 x 9.8 x 0.05
P = 490 N/m²
Therefore, the pressure exerted at the base of the container is 490 N/m²
An object's speed is 0.8 m/s, and its momentum is 200 kg-m/s What is the mass of the object?
A. 250kg
B. 200kg
C.160kg
D.128kg
Answer:
A: The mass would be 250kg
Explanation:
In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object. where m is the mass and v is the velocity. The equation illustrates that momentum is directly proportional to an object's mass and directly proportional to the object's velocity.
p= mv
m= p/ v
The explanation to that is:
momentum = mass× velocity
mass= momentum / velocity

Answer:
Atomic models are important because, they help us visualize the interior of atoms and molecules, and thereby predicting properties of matter.
Explanation:
We study the various atomic models in our course of study because, it is important for us to know, how did people come to the present concept of an atom. How did physics evolve from classical to quantum physics.
All these are important for us to know and thus, knowledge about various atomic models, their discoveries and drawbacks and finally improvements based on scientific evidence present at that time is important for us to understand the underlying theory very well.

Activat
Answer:
Soundwave should be categorized as follows;
A mechanical wave that has longitudinal vibrations
Explanation:
Sound wave should be categorized as longitudinal waves that vibrate the particles of the medium transmitting sound energy layer by layer along a path parallel to the direction of propagation of the wave
Therefore, soundwave should be categorized as a mechanical wave because it is generated and propagated by the vibration of a source and the interaction of the source with the particles of the medium in which the source is located
soundwave is also a longitudinal wave because the direction of vibration of th particles of the medium through which the sound wave is transported is in the same direction as the wave
Therefore, sound wave should be categorized as mechanical wave that has longitudinal vibrations.
The soundwave should be categorized where the mechanical wave that has longitudinal vibrations
What is a sound wave?
It should be categorized at the time when the longitudinal waves should be vibrated the particles with respect to the medium transmitting via layer along with it the path should be parallel to the propagation direction of the wave. Also, it should be categorized as the mechanical wave since there should be the vibration of the source.
