The distance between earth and sun is 15000000km. Light takes 499 seconds to reach earth from sun. Calculate the speed of light
2 answers:
To solve the problem we must know about the relationship between Speed, distance, and Time.
<h3>What is the relationship between Speed, distance, and Time?</h3>We know that sped, distance, and time all are in a relationship to each other. this relationship can be given as,
The speed of the light is 30,060.12 km/sec.
Given to us
- The distance between the earth and the sun is 15000000km
- Light takes 499 seconds to reach earth from the sun.
We know that speed can be described as,
Therefore,
<h3>What is the speed of the light?</h3>Substitute the value,
Hence, the speed of the light is 30,060.12 km/sec.

Answer:
117 m/sec is the speed of a transverse wave in a rope of length 3. 1 m and mass 86 g under a tension of 380 n.
The wave speed v is given by
v= √τ/μ
where τ is the tension in the rope and μ is the linear mass density of the rope.
The linear mass density is the mass per unit length of rope :
μ= m / L = (0.086 kg)/(3.1 m)=0.0277 kg/m.
v= = 117.125 m/sec (approx. 117 m/sec
In physics, a transverse wave is a wave whose oscillations are perpendicular to the direction of the wave's advance. This is in contrast to a longitudinal wave which travels in the direction of its oscillations. Water waves are an example of transverse wave.
Transverse waves commonly occur in elastic solids due to the shear stress generated; the oscillations in this case are the displacement of the solid particles away from their relaxed position, in directions perpendicular to the propagation of the wave. These displacements correspond to a local shear deformation of the material. Hence a transverse wave of this nature is called a shear wave. Since fluids cannot resist shear forces while at rest, propagation of transverse waves inside the bulk of fluids is not possible.
