Derive Isothermal process through ideal gas.(anyone plzz!!)​

Answer:

High in the atmosphere, air pressure decreases. ... A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet. As the air rises, the water vapor within it condenses, forming clouds and often precipitation.

Explanation:

The Earth pulls the bicycle downward through the force of gravity, and, in response, the bicycle pulls up on the Earth with a force of equal magnitude. Gravity "pushes" the Earth into the road, which pushes up with an opposite force, canceling gravity. Thus, action reaction forces do not cancel each other.

Answer:

The frictional force on the block is 118 N.

Explanation:

Given;

horizontal force applied on the block, f = 80 N

mass of the block, m = 20.0 kg

coefficient of friction, μ = 0.6

The frictional force on the block is calculated as;

F = μR

F = μ(mg)

F = 0.6(20 x 9.81)

F = 117.7 N

F = 118 N.

Therefore, the frictional force on the block is 118 N.

Answer:

It is option A

Explanation:

a p e x

Point A on the standing wave is the result of the constructive interference of two crests. The effect is the sum of the individual wave amplitudes at each site where more than one wave is present.

The result of two or more wave trains flowing in opposite directions on a crossing or coinciding pathways. This phenomenon is known as the interference of waves.

When two wave pulses are traveling along a string toward each other. They meet, and the phenomenon is occurring, known as interference.

The distance between two successive troughs or crests is known as the wavelength. The peak of the wave is the highest point known as crest.

Point A on the standing wave is the result of the constructive interference of two crests.

Hence, option A is correct.

Answer:T

Explanation:

i feel like it doesn't have enough info

High pressure systems entail sinking air, while lows entail rising air. High pressure systems form where air converges in the higher levels of the atmosphere. The converging air has nowhere to go and is forced to sink toward the ground. This sinking effect inhibits cloud formation and therefore precipitation.

Answer: C: The moons orbit around the earth.

Explanation:

Answer:

0.35

Explanation:

According to Newton's second law;

\sum Fx = ma

Fm - Ff =ma

Fm is the moving force = Wsin theta

Fm = 4(9.8)sin55

Fm = 32.1N

Ff is the frictional force = nmgcos theta

Ff = n(4)(9.8)cos55

Ff = 22.48n

Acceleration a = 6.0m/s²

Substitute the given values into the formula and get the coefficient of friction

32.11-23.48n = 4(6)

32.11-24= 23.48n

8.11 = 23.48

n = 8.11/23.48

n = 0.35

Hence the coefficient of friction is 0.35

Answer: 10.526m/s

Explanation:

The speed of the toy car would be calculated as the distance travelled by the toy card divided by the time taken. This will be:

= Distance travelled / Time taken

= 60/5.7

= 10.526m/s

The speed of the toy car is 10.526 meters per second.

If an object is given an initial velocity in any direction and then allowed to travel freely under gravity, it is called a projectile motion.

It is basically 3 types.

Answer:

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.

Answer:

The speed of the wave as it travelled through the brass bell is;

B. 4,700 m/s

Explanation:

The given parameters are;

The wavelength of the sound wave produced from the brass bell, [tex]\lambda _{(air)}[/tex]  = 3.5 m

The wavelength of the wave in the brass bell, [tex]\lambda _{(brass \ bell)}[/tex]  = 47 m

The frequency of the wave in the brass bell, f = 100 Hz

The given equation for wave speed, v = f × λ

Therefore, the speed of the wave as it travelled through the brass bell, [tex]v _{(brass \ bell)}[/tex], is given as follows;

[tex]v _{(brass \ bell)}[/tex] = f × [tex]\lambda _{(brass \ bell)}[/tex] = 100 Hz × 47 m = 4,700 m/s  

The speed of the wave as it travelled through the brass bell =  [tex]v _{(brass \ bell)}[/tex] = 4,700 m/s

Distance between them  = ?

Solution:

To solve this problem, we use the expression below from the universal gravitational law;

     Fg  = [tex]\frac{G x mass 1 x mass 2}{distance^{2} }[/tex]  

G = 6.67 x 10⁻¹¹

     1.067 x 10⁻⁵  = [tex]\frac{6.67 x 10^{-11} x 1000 x 1000 }{d^{2} }[/tex]

Answer:

[tex]75\:\mathrm{seconds}[/tex]

Explanation:

The impulse-momentum theorem states that the impulse of an object is equal to the change in momentum of that object:

[tex]\Delta p=m\Delta v[/tex].

Impulse is also given by [tex]F\Delta t[/tex] where [tex]F[/tex] is the average net force and [tex]\Delta t[/tex] is change in time.

Therefore, we can set both equations equal to each other and solve:

[tex]\Delta p= F\Delta t[/tex].

Assuming that the airplane was initially at rest, its change in momentum is:

[tex]\Delta p =m\Delta v,\\\Delta p=30,000\cdot 50=1,500,000[/tex]

Impulse is represented using [tex]Ns[/tex]. Therefore, convert [tex]20\:\mathrm{kN}[/tex] to Newtons:

[tex]20\:\mathrm{kN}=20,000\:\mathrm{N}[/tex]

Thus:

[tex]1,500,000=20,000\cdot t,\\t=\frac{1,500,000}{20,000}=\fbox{$75\mathrm{s}$}[/tex].
