Answer:
33.33 m/s
Explanation:
m = 450 kg. T = 5000 N, t = 3 seconds,
let the net acceleration is a.
T = m a
a = 5000 / 450 = 11.11 m/s^2
u = 0 , v = ?
Let v be the velocity after 3 seconds.
Use first equation of motion
v = u + a t
v = 0 + 11.11 x 3 = 33.33 m/s

Explanation:
T = Temperature
b = Constant of proportionality = 
= Wavelength

From Wein's law we have

The wavelength of the radiation will be
and it is in the ultraviolet region.


The wavelength of the radiation will be
