The track has a circumference of 400 m. This is the distance traveled per lap.
Because the person made 8 laps, the total distance traveled is
8 * 400 = 3200 m
The time taken for the 8 laps is 14.0 min = 14*60 = 840 s.
The average velocity
= distance/time
= (3200 m)/(840 s)
= 3.8095 m/s
Answer: 3.8 m/s (nearest tenth)
Answer: Peak wavelength
{lambda max}
= 9.7*EXP{-7}meter
Which is approximately,
1 micro-meter.
Explanation: lambda{max} which is peak wavelength is inversely proportional to temperature {T}.This is given by the wiens displacement law.
Lambda max
=max displacement{Xmax} / T
For the first case at T = 6000K
Lambda max = 483 nano-meter
=483*EXP{-9}meter.
So let's solve for max displacement {Xmax}.
Xmax = T*lambda max
= 6000*483*EXP{-9}
=2.898*EXP{-3}kelvin-meter
Xmax would be constant during Temperature change.
Therefore lambda max at 3000K would be,
Lambda max
= {2.898*EXP{-3} K-m} / 3000K
= 9.7*EXP{-7} meter
Which is approximately,
1*EXP{-6} meter= 1 micro-meter
NOTE: EXP used here means 10^.
According to the trichromatic theory of color vision, also known as the Young-Helmholtz theory of color vision, there are three receptors in the retina that are responsible for the perception of color. One receptor is sensitive to the color green, another to the color blue and a third to the color red.
Hope this helps.
Solution is given in following attachment.
A deuteron is related to deuterium, which is hydrogen with one neutron in the nucleus.
The charge on the deuteron is 1.6x10^-19C.In half a rev, the charge gets a force of Eq on it.
