Can anyone prove ADIABATIC PROCESS ???​

Answer:

The planets spun in epicycles.

Explanation:

The planets were not simply attached to a mystical sphere (“deferent”) but they were actually attached to a mini-sphere (“epicycle”) which rotated on the larger one.

Answer:A

Explanation:

Answer:

C. a mixture of two or more substances. It is homogeneous at the molecular level

Answer:

C M (change in T) = heat absorbed      thermal equation for heat gained

C = 418.4 J / (2 kg * 50 deg K) = 4.184 J / kg * deg K     specific heat

Note: 1 gm =.001 kg

So C = .004184J / gm * deg K

Also, 1 J = .239 cal   so in conventional terms

C = .001 cal / gm deg K     (very low, water would be 1 cal / gm deg C

Answer:

[tex]1.5\cdot 10^{-5}\:\mathrm{N}[/tex]

Explanation:

Newton's Law of Gravitation is given as:

[tex]F=G\frac{m_1m_2}{r^2}[/tex], where [tex]G[/tex] is gravitational constant [tex]6.67\cdot 10^{-11}[/tex] and [tex]r[/tex] is the distance between their centers of mass.

Therefore, the gravitational force between them is:

[tex]F=6.67\cdot 10^{-11}\frac{55\cdot40}{0.1^2}= \fbox{$1.5\cdot 10^{-5}\:\mathrm{N}$}[/tex] (two significant figures).

Explanation:

Answer:

Gases

Solids

Liquids

Explanation:

A)The molecules are a great distance apart, moving  very rapidly, with negligible interaction. The  substance occupies all the space available.

Gases

The state of matter described above is for gases. The distances between gases are far apart and they have very weak intermolecular attraction. They have no fixed volume as they occupy any volume of space they are introduced into.

B)The molecules are only able to vibrate rapidly about  fixed positions. The substance does not need a  container to maintain its shape.

Solids

Solids have fixed shape and volume. They are held together in their fixed lattice and are only able to rapidly vibrate about their fixed positions.

C)The molecules move about amongst each other,  with attractive forces between them. The substance  does not necessarily fill its container.

Liquids

The state of matter described here are the liquids. Liquids flow amongst each other. The attractive force between them is greater than that of gases but lesser than those of solids.

Answer:

6

Explanation:

From the given question, since a total of 12 V was obtained from the battery which is made up of a number of cells with each producing 2.0 V.

Assuming that the cells have a very low internal resistance, then;

minimum number of electric cells in the car battery = [tex]\frac{total voltage from the cells}{individual voltage of the cells}[/tex]

                                          = [tex]\frac{12}{2}[/tex]

                                          = 6

Thus, the minimum number of electric cells in the car battery is 6.

This implies that the addition of 6 cells which has 2.0 V supply in the battery produces a total of 12 V. Provided that the cells have a very low internal resistance.

Answer:

Refractive index is a measure of how light propagates through a material. The higher the refractive index the slower the light travels, which causes a correspondingly increased change in the direction of the light within the material.

Explanation:

Answer:

A atmospheric composition

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s

0.184[tex]m^{3}[/tex] is the answer for Acellus students!

Answer:

D. All of the above

Explanation:

Global warming may cause all of the given choices.

Global warming is the rise in surface temperature. This is due to the trapping of heat within the earth surface.

It is as a result of huge amount of greenhouse gases within our atmosphere. They typically permit short wave radiations to escape and they do not allow short wave radiation to pass through. This in turn produces heat.

En física estas siglas significan movimiento rectilíneo uniforme, es decir es el tipo de movimiento donde la velocidad es constante. La velocidad no cambia con el tiempo.

Este tipo de movimiento se puede describir con la siguiente ecuación.

[tex]x=x_{0}+v*t[/tex]

Donde:

x = posición final [m]

xo = posición inicial [m]

v = velocidad [m/s]

t = tiempo [s]

Answer:

Explanation:

When a player throws a football , he applies force on the ball , due to which ball accelerates in forward direction . This is the action force .

The ball also applies a force on the hand of the player . Due to it the player experiences a pushing force in backward direction . This is reaction force .

Due to this force , the player does not move in backward direction because of frictional force of the ground . The frictional force keeps him stationary .

The options are not shown, so it is kinda hard to give you the exact answer.

But i can try to give a general explanation on the topic.

Interference happens when two waves interact between them. We usually use waves with the same wavelength and same phase.

There are two "main" types of interference:

Destructive interference: Happens when the peak of one wave and the trough of the other wave happen in the same place, then when we add these waves, we have a subtraction, and then the amplitude of the resultant wave is smaller than the amplitudes of the original waves (if both initial waves have the same amplitude, then the amplitude of the resultant wave in that position is zero).

Constructive interference: Similar to the previous case, but now the two waves have the peaks or toughs in the same position, then when we add the waves, we have an addition in the amplitude, then the amplitude of the resultant wave will be larger than the amplitudes of the initial waves.

Then if you are looking for constructive interference, you need to look for an option where the peaks of the waves coincide. For example, in the top image we can see, at the top, a wave with an amplitude of 2 units.

And at the bottom a wave with an amplitude of 1 unit.

We also can see that the peaks (and the tough) are in the same place, then we will have constructive interference. Then the amplitude of the resultant wave will be equal to the sum of the amplitudes of the initial waves (2 and 1)

Then the amplitude of the resultant wave is 2 units + 1 unit = 3 units.

Explanation:

Torque in physics is defined as the product of force by distance. This way you can use the following equation to calculate the torque.

[tex]T=F*d[/tex]

where:

T = torque [N*m]

F = force [N]

d = distance [m]

Now replacing in the equation above.

Answer:

11.025m

Explanation:

In this question there is no vertical velocity,

t= 1.5s

Height of platform=h

From Newton equation

s = ut + 1/2gt^2

But there is no vertical velocity,

Hence,

Then u=0

h = 0 + 1/2 x 9.8 x (1.5)^2

h = 11.025m

Velocity of sound travels faster in solids than in liquids, and faster in liquids than in gases because "the density of solids is higher than that of liquids, meaning that the particles are closer together."

Answer:

Explanation:

Due to the fact that sound is caused by vibrations, it's more noticeable in liquid because the vibrations may cause ripples in the liquid

The thing same about a particle as gas, liquid, or solid is its chemical composition.

Matter exists in three different states: solid, liquid, and gas. By examining the configuration of their particles, it is possible to understand why they have various qualities. Theoretically, at this temperature, particles move slowly and have the least amount of energy.

Phase refers to the material's actual state. To pay attention to is the word physical. Only physical means can change the state of matter. You can make a physical change if energy is added (by raising the temperature) or subtracted (by freezing things).

The chemical composition of matter same about a particle as gas, liquid or solid.

Answer: B. Mechanical Waves

Explanation:

Answer:

The option which is not a criteria for a celestial object to be a planet is;

The object must be massive enough have a gravitational pull on the Sun

Explanation:

There are three criteria for a celestial object to be classified as a planet including;

1) The object's orbit is around the Sun

2) The shape of the object is nearly round due to its mass which is capable of assuming hydrostatic equilibrium

3) Other smaller objects in the neighborhood around the object has been cleared by the object

Therefore, the option which is not a criteria for a celestial object to be a planet is that it must be massive enough to have a gravitational pull on the Sun as every two objects in the Universe share a common gravitational pull according to Newton's Law of Gravitation.
