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.

Answer: A I think
Explanation:
in hydraulic pressure the area of the larger piston is half of the smaller piston.if the force of 4000N is applied on the smaller piston.what is the distance covered by the train ?
Answer:
The distance moved by the train is half the distance moved by the force
Explanation:
Given that the force applied to the smaller piston, F₂ = 4,000 N
The pressure in the area of the larger piston, A₁ = 2 × The pressure in the smaller piston, A₂
∴ A₁ = 2 × A₂
We have;
[tex]\dfrac{A_1}{A_2} = \dfrac{2\cdot A_2 }{A_2} =2 = \dfrac{F_1}{F_2}[/tex]
F₁ = 2·F₂ = 2 × 4,000 N = 8,000 N
F₁·d₁ = F₂·d₂
∴ 8,000 N ×d₁ = 4,000 N × d₂
d₁ = 1/2·d₂
∴ The distance moved by the train is half the distance moved by the force
The tuning fork has a frequency of 426.7 is found to cause resonance in a closed column of air measuring 0.186 (the diameter of the tube is 0.015m) find the velocity of the sound produced by the tuning fork.
Answer:
The velocity of the tuning fork sound is 317.4648 m/s
Explanation:
The given parameters are;
The frequency of the fork, f = 426.7 Hz
The length of the closed air column, L = 0.186 m
The diameter of the tube, d = 0.15 m
At the fundamental frequency in a closed tube, we have;
λ = 4·L
Where;
λ = The wavelength of the wave
L = The length of the tube
From the equation for the velocity of a wave, we have;
v = f·λ
Where;
v = The velocity of the (sound) wave
f = The frequency of the wave = 426.7 Hz
λ = 4·L = 4 × 0.186 m = 0.744 m
∴ v = 426.7 Hz × 0.744 m = 317.4648 m/s
Therefore, the velocity of the sound produced by the tuning fork, v = 317.4648 m/s

PLZZZZZZZZZ HELPPPPP. BRAINLEST GIVEN What is a force of attraction between an object and the earth due to gravity?
Answer:
acceleration due to gravity: -9.8 m/s^2
Fg=mass of object*(-9.8)
Explanation:
This is a pretty vague question, but I'll answer as best I can.
All matter has gravity. YOU have gravity, although your gravitational pull is small. So, the force of attraction between the Earth and an object on Earth is modeled as
Force of gravity=(Gravitational constant*mass of object 1*mass of object 2)/distance between objects squared
Note that distance between an object on Earth and Earth is the radius of Earth (distance to Earth's core/center of mass)

Join a club if you want to meet people, and when they choose a hobby it should be more than just gardening, because gardening sucks in the long term and it doesn't fill that gap. I know because my grandma did it and she is still sad.
What is the unit of energy called? (Give name and symbol)
a) A 12 kg object has a velocity of 37.5 m/s. What is its momentum?
b) How far does it get in 16 s?
Answer:
The answer would be 450 m kg/s
Explanation/ Explanation / Example:
Provided an object traveled 500 meters in 3 minutes , to calculate the average velocity you should take the following steps: Change minutes into seconds (so that the final result would be in meters per second). 3 minutes = 3 * 60 = 180 seconds , Divide the distance by time: velocity = 500 / 180 = 2.77 m/s .

If a motor is rated at 5.6KW, work done in 20minutes is equal to:
Answer:
given Power= 5.6×1000=5600watt
t=20min=20×60=1200sec. work done=?
P=w/t
w=pt=5600×1200=672×10^4Joule
The amount of work done by the motor is equal to 6.72 Megajoules.
Given the following data:
Time = 20 minutesPower = 5.6 Kilowatt = 5600 Watts.Conversion:
1 minute = 60 seconds20 minutes = [tex]20 \times 60 = 1200[/tex] seconds.To determine the amount of work done by the motor:
Mathematically, the work done by an object with respect to power and time is given by the formula:
[tex]Work\;done = power \times time[/tex]
Substituting the given parameters into the formula, we have;
[tex]Work\;done = 5600 \times 1200[/tex]
Work done = 6,720,000 Joules

A stone of mass 0.2kg is thrown vertically upwards from the ground with a velocity of 20m/s. Find the maximum height attained by the stone
Answer: 20.4 m
Explanation: speed v upward is v = vo -gt.
When maximum height v = 0, vo -gt = 0 and
T = vo / g = 20 m/s / 9.81 m/s² = 2.04 s
Now height y = vot -0.5 gt^2 = 20,4 m
This is possible to solve using
Conservation of energy Ek= Ep

If two monochromatic light waves undergo destructive interference, the amplitude of the resultant wave is
Answer: The amplitude is 0. (assuming that the amplitude ot both initial waves is the same)
Explanation:
When two monochromatic light waves of the same wavelength and same amplitude undergo destructive interference, means that the peak of one of the waves coincides with the trough of the other, so the waves "cancel" each other in that point in space.
Then if two light waves undergo destructive interference, the amplitude of the resultant wave in that particular point is 0.
Answer:
No, the resulting wave in the diagram does not demonstrate destructive interference. The resulting wave in the diagram shows a bigger wave than Wave 1 or Wave 2. If it demonstrated destructive interference, it would be a smaller wave or a horizontal line. With destructive interference, waves break down to form a smaller wave, or cancel each other out, resulting in no wave formation.
