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^.
Arete is a sharp ridge separating two cirques or glacial vallies found in mountain regions. It is French for fishbone or the backbone of a fish, spine
Radiation is the transfer of energy thru waves, conduction is when thing touch or have contact with each other. And convection is where heat is being carried, hope this helps have a great day! :)
Using the impulse-momentum theorem and taking this down as positive, we will get:
FΔt = Δp
F = Δp / Δt
= m(v - v₀) / t
= 0.056kg [13m/s - (- 20m/s) / 0.00125s
= 1478.4 N when properly rounded off is the answer we are looking for in this problem.
