The process in which a substance changes from a gaseous state to the liquid state is A. critical temperature.
B. absolute zero.
C. evaporation.
D. condensation.
Answers
You can easily notice this happen on Air conditioning devices, where the cold gaseous air is turned into water that drips from the air conditioning unit due to condensation.
By definition we have to:
In physics, condensation is a change of state by which a substance passes from a gaseous state to a liquid state.
For example, in a refrigeration cycle, the refrigerant leaves the compressor in the gaseous state, from here, it enters the condenser, a state change called condensation occurs and the refrigerant leaves in liquid form. This process is useful in air conditioners.

D. condensation.

on a boundary with corn oil. What is the angle of refraction, to the nearest degree, for this
light ray in the corn oil?
Answers
The angle of refraction of light ray in the corn oil is 20°.
What is angle of Refraction?
Angle of refraction is the angle the refracted light ray makes with the normal to the oil-air interface.
Given data:
Angle of incidence = 30°
Analysis:
The refractive index of oil is 1.47.
Using the formula for refractive index(n) =
1.47 =
1.47(sin r) = sin 30
sin r =
sin r = 0.3401
r = arc sin(0.3401)
r = 19.88° which is approximately 20°

We know that there is a formula velocity = frequency x wavelength for all types of waves.
If we assume one complete oscillation of a pendulum to be wavelength we can apply the above formula for the pendulum too.
So as v = fλ and f = v/λ we can just plug in the values to get our answer of frequency.
So frequency = 30/0.35 which is equal to 85.17 Hertz (Hz).
I think you're trying to take the formulas for speed, wavelength, and
frequency of a wave, and apply them to a pendulum. You can't do that.
It doesn't work.
A pendulum is moving in 'simple harmonic motion', not wave motion.
It's speed is continuously changing, from zero at both ends of its swing,
to maximum as it passes through the 'rest' position at the bottom. And
there's no wavelength defined for a pendulum ... if you're thinking that
it could be the distance from end to end of its swing, or maybe half of
that, you should know that the frequency of an ideal simple pendulum
is not related to that distance at all.
Finally, in the real world, the numbers in this question really kind of
don't make any sense. You have a structure where some part of it is
roughly a foot long (0.35m = 13.8 inches), and at least at some point
during its swing, something is moving at 30 m/s ... about 67 mph !
If something like that could even stay on the table, and IF its frequency
were (speed/wavelength) ... like a wave's frequency is ... then its frequency
would be (30 / 0.35) = 85.7 Hz ! ! The thing would be wiggling back and
forth every 0.017 second ! It would need to be operated only inside
a bomb shelter, with all personnel withdrawn beyond a safe perimeter
before it flies apart and scatters shrapnel everywhere.

D. 1,500 m/s
Explanation
the wave equation states that,
V = λf
Where V ⇒ Velocity
λ ⇒ wavelength
f ⇒ Frequency
F = 1/T
Where T ⇒ period
F = 1/0.006
= 166.667
∴ V = 9 × 166.667
= 1,500 m/s

The correct answer is B) Conductor
A conductor is a material that allows for the flow of electrical charge (electrical current). This type of material provides little or no resistance to the flow of electric current. This is due to the fact that these type of materials have free electrons which conduct the flow of electrical current in any direction.
Different types of conductors have different resistances. Some types of materials are good conductors whereas some are not so good.
Some common conductors are Copper, gold, silver and aluminium.
An insulator is the an object of type of material which have a strong resistance to the flow of electric current. Some common insulators are glass, wood and plastic.
