Study the image of a seismic graph.Graph of P & S Wave Travel Times, showing Travel time in minutes across distance in kilometers for P and S waves. S wave starts at zero kilometers, zero minutes, and increases to 10,000 kilometers, 25 minutes. P wave starts at zero kilometers, zero minutes and increases to 10,000 kilometers, 13 minutes.
About how far does the S wave travel through Earth in 13 minutes?

Different colors after reflection appear due to the different wavelengths of light. Therefore, option C is correct.
What are frequency and wavelength?
The wavelength of the light can be defined as the distance between the two points in phase w.r.t. each other such as two crests or troughs on a wave. The frequency of the light is the number of oscillations of a wave in one second and has S.I. units of per second or hertz.
The expression between frequency (ν), wavelength (λ), and speed of light (c) is:
c = νλ
A wave moving at a fixed wave speed has a wavelength that is inversely proportional to the frequency therefore, the waves with higher frequencies have shorter wavelengths, while lower frequencies have higher wavelengths.
The speed depends upon the medium as it propagates. In particular, the speed of light in a particular medium is less than in a vacuum, therefore the same frequency will have a shorter wavelength.
When the light is reflected the colors are formed as due to different wavelengths.

Answer:
25N
Explanation:
Find acceleration first
A=v-u/t
acceleration = 5/0.1s =50m/s^2
then find net force using f=mass x acceleration, which iin this case is 25N

Answer:
Neglecting, air resistance, friction and breaking, all the condition has conservation of mechanical energy.
Explanation:
- The law of conservation of mechanical energy suggests that the mechanical energy in a locked system with out any destructive forces like friction or air resistance remains always the same (constant).
- The energy may be converted between kinetic energy, potential energy, gravitational potential but energy do not get decreased in any cases as mentioned in the option.
- So all the cases mentioned above shows the conservation pattern of mechanical energy.
