hiii pls help i’ll give brainliest thank you

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

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

Answer:

Inorganic.

Explanation:

The chemical change which describes the reactions of elements and compounds that, in general, do not involve carbon and typically take place in laboratories or industries is inorganic.

In Chemistry, an inorganic chemical reaction can be defined as a type of chemical reaction that occurs without a carbon-hydrogen bond.

On the other hand, organic chemistry deals with reaction that occur in the presence of carbon-hydrogen bonds such as hydrocarbons.

Joining a club and getting a hobby

Explanation:

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.

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

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:

Calor absorbido, Q = 52325 Joules

Explanation:

Dados los siguientes datos;

Masa = 250g to kg = 250/1000 = 0.25kg

Temperatura inicial, T1 = 10°C to Kelvin = 273 + 10 = 283K

Temperatura final, T2 = 60°C to Kelvin = 273 + 60 = 333K

Capacidad calorífica específica = 4186 j/kg.K.

Para encontrar la cantidad de calor necesaria;

La capacidad calorífica viene dada por la fórmula;

[tex] Q = mct [/tex]

Dónde;

Q representa la capacidad calorífica o la cantidad de calor.

m representa la masa de un objeto.

c representa la capacidad calorífica específica del agua.

dt representa el cambio de temperatura.

dt = T2 - T1

dt = 333 - 283

dt = 50 K

Sustituyendo en la fórmula, tenemos;

[tex] Q = 0.25*4186*50[/tex]

[tex] Q = 52325 [/tex]

Calor absorbido, Q = 52325 Joules

Line - A:  (15/10)  =  1.5 inch/second

Line - B:  (0/10)  =  0

Line - C:  (10/10)  =  1.0 inch/second

Line - D:  (-25/20)  =  -1.25 inch/second

Line-A represents the greatest speed.

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

0.5mv² = mgh. And h = v²/2g. Results same

Explanation:

Charge willl not flow through a diode (in the reverse directiom)

BECAUSE A DIODE HAS A VERY HIGH RESISTANCE IN THE REVERSE DIRECTION

Answer:

v=s/t

s=vt

t=s/v

t=(120×10‐³)/172.8

(the distance meters has been changed to kilometres)

t=1/1440 hrs

Given ,

Answer:

If F is a constant, we can take f = 1

f = m×a

ma = 1

therefore we can say that force is hence proportinal to the product of mass and acceleration.

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 .
