The correct answer to the question will be B) Both can be characterized by amplitude, frequency, and wavelength. The speed of both is affected by the medium through which it travels.

EXPLANATION:

Light is an electromagnetic wave which is transverse in nature. It contains both the electric field and magnetic field which are perpendicular to each other as well as perpendicular to the direction of propagation.

We know that a transverse wave is characterized by its amplitude, frequency and wavelength . Here, crests and troughs are created which give the idea about the wavelength . The distance between two successive crests or troughs is called wavelength.

A sound wave is a longitudinal wave which moves in the form of compressions and rarefactions. Compressions are the high pressure zones while rarefactions are the low pressure zones in the wave. Here, the distance between two successive compresions or rarefactions is called wavelength of the wave. It is also characterized by frequency and amplitude.

The speed of light is medium dependent . It is more in optically rarer medium while less in optically denser medium . The light does not require any medium for its propagation. It may propagate through space where it has the maximum velocity.

The speed of sound is also medium dependent . It depends on the density and elasticity of the medium.It can not travel through vacuum. It needs a medium for its propagation.

A scientist counts the number of bacteria colonies growing in each of six lab dishes.

Hi!

The correct answer is: C. It is the data value that appears the most often in the set.

<h3>Explanation</h3>

The mode of a set of values is the number which is the most frequently appearing, or most repeating value in the range. The numbers that show one time each are

A - 16 , C - 25 , D - 3

While 13 appears three times with the dishes labelled

B , E and F

So, the value that appears the most times is 13, and hence 13 is taken as the mode of this data set

If a 2000 N force is used to raise a piano at a rate of 10 m/s2, what is the mass of the piano?

saveliy_v [14]

Answer:

To solve this problem we will apply the principle of conservation of energy for which we have that the potential energy on a body, is equivalent to the work done on it at the given point. Therefore we will have the following equality

At the same time we know that work is equivalent to the Force applied over a given distance, so,

The potential energy is equivalent to the product between mass, gravity and height. Recall that the product of mass and gravity is equivalent to weight (The same given in the statement)

Equating,

Then,

Replacing,

Therefore the force needed to lift the piano is 600N

What is the wavelength of a radio photon from an "am" radio station that broadcasts at 1080 kilohertz?

asambeis [7]

<span>208.3 meters The product of the wavelength multiplied by the frequency will equal the speed of light which is 299792458 m/s. Simple algebra will tell you that you can divide the speed of light by the frequency to get the wavelength. So 224997958 m/s / 1080000 1/s = 208.3314426 m Rounding to 4 significant digits gives you 208.3 meters.</span>
