In order to get the propoerty of work you need to use the following formula
<span>work = force times distance
</span>replacing data you will get:
W = (1.500) (3)
W = 4.500 NM
The answer should be in NM. So it will be 4500 NM againts the force of gravity
Such information is valid when A. it is not biased.
There is no bias in science - the results are either correct or incorrect; personal opinions have nothing to do with that. B is incorrect because the point of experiments is that they can be repeated to achieve the same results. C and D are likewise incorrect as primary sources are important, and you can share the results with others if you want to.
Answer:
The correct answer is option D.
Explanation:
Acoustic : A branch of physics which study the properties of sound.
Consonance: Combination of notes occurring simultaneously due to relationship between their respective frequencies.
Timbre: A characteristic of a musical note which makes it distinct from another wave which also have same pitch and intensity.
Dissonance :When combination of two notes are played simultaneously with lack of harmony in between them.
Hence, the correct answer is option D.
Answer:
in a vacuum
Explanation:
Electromagnetic waves are waves consisting of oscillations of electric and magnetic fields along a plane perpendicular to the direction of propagation of the wave (transverse waves)
Electromagnetic waves are the only waves being able to travel in a vacuum, since they do not need a medium to propagate.
In a vacuum, all electromagnetic waves travel at the same speed, called speed of light, whose value is:

The speed of the waves is actually reduced when they enter a medium, according to

where n is the refractive index of the medium.
Electromagnetic waves are also classified into 7 different types according to their wavelength. From shortest to longest wavelength, we have:
Gamma rays
X-rays
Ultraviolet
Visible light
Infrared
Microwaves
Radio waves
