The prefix "mega" means million.
Therefore
1 megameter = 10⁶ meters
That is,
1.0 megameter = 1,000,000.0 meters.
Answer:
The decimal is moved right by 6 places to convert a megameter to meters.
Given that,
Time period of simple pendulum is 1.55 s.
Time period of simple pendulum for A student =1.25 s
Time period of simple pendulum for B student =1.5 s
We know that
The accuracy is defined as how close a measurement is to a known value .
The result of student of A is 1.25 s. It is more precise because it has more significant figure than student B's result of 1.6 s.
But the measurement made by student B's is much closer the known value of 1.55 s.
Hence, The most probable source of error is the result of student A.
<span>A star's motion towards or away from us is detected by the wavelength of the spectral lines.
Because when a star is moving toward us or away from us, the apparent color does not change but there is a change in the wavelength of spectral lines, when the stars are moving towards us, the spectral lines are towards red end and when they are moving away from us the spectral lines are towards the blue end.</span>
