Power
The is the rate of energy used to time. It is the measure of expedience of energy.
a). How many minutes is the dryer used in a month.
Assuming there 30 days in a month;
This shows that the dryer is used 300 minutes in a month.
b). How many hours is the dryer used in a month.
To solve this problem, we simply need to convert the value of (a) from minutes to hours.
The dryer was used for a total of 5 hours in a month.
c). The power of the dryer in kilowatt.
To convert the power in watt to kilowatt, we divide by 1000.
The power in kilowatt is 1.2kw
d). How many kilowatt/hr of electricity used in a month.
The dryer consumes 6kw/h in a month.
e). If the town charges $0.15/kwh, the cost in a month
The cost of the dryer in a month is $0.9.

Earthquake S-wave, radio waves, X Ray's, Visible light are examples of transverse waves.
What are waves?
Wave can be defined as any form of disturbance which is transmitted through a medium and energy is transferred from one medium to another thereby causing displacement of the medium.
A Transverse wave is a type of wave in which the wave there is a vibration of the wave medium which is as a result of the wave movement which now become perpendicular to the direction of the wave.
Therefore, Earthquake S-wave, radio waves, X Ray's , visible light are examples of transverse waves.

B.The surface of the lake is transparent.
C.The surface of the lake is polished.
D.The surface of the lake is rough.
Answers
Answer: The correct answer is "The surface of the lake is smooth".
Explanation:
The light gets reflected from the smooth surface at the same angle as it hits that surface. If the light gets reflected in all direction from the rough surface when it hits the surface. Then, there will be diffuse reflection.
In the given problem, Leon sees a poster that shows a lake in front of a snow-capped mountain. The mountain appears upside down in the lake. Here, the water acts like a mirror. The light rays incident on the surface of the water from the mountainthen the reflected rays get reflected back from the smooth surface of the lake. Here, the angle of incidence is equal to the angle of the reflection.
One can see the image of the object on the surface of the lake.
Therefore, the correct option is (A).
Answer:
the answer is a.

The wording of the question is fundamentally defective,
and the question is therefore unanswerable. (But I'll
gladly accept your points anyway.)
"Amplitude" is the origin of the subjective impression of loudness.
"Pitch" is not.
There is no such concept as the 'loudness' of a pitch.
what is your weight on the Sun?
Answers
If someone have weight that is force due to gravity is X than on the sun it will become 28 X.
What is force?
A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
Mass of body is constant on any place in the universe and weight changes with acceleration due to gravity so, at sun weight will be 28 X.
If someone have weight that is force due to gravity is X than on the sun it will become 28 X.
