Answer:
The peak wavelength of the light it irradiates decreases
Explanation:
As the temperature of a blackbody increase, the peak wavelength of the light it radiates decreases, this follows Wien's Law.
A blackbody is an ideal substance that emits all frequencies of light and also has the ability to absorb them as well.
Wiens displacement law, explains that the position of the peak wavelength of the thermal radiation emitted by bodies can change with temperature, and as the temperature increases beyond a certain point, the wavelength begins to reduce. This often changes the colour of the light emitted from heated objects.
L = 15cm = 0.15m
A = 0.15 × 0.15 = 0.0225
Sradiation is transfered from bottom
σ = 5.67 × 10⁻⁸ W/m²k
T = 605 c = 878k
Rate of energy transfer
Q = σ × A × E × T⁴
5.67 × 10⁻⁸ × 0.0225 × 2 × 0.8 × 878⁴
1792.17 W
Do what?? i know how to do a lot of things to answer but there’s nothing to answer.♀️
Answer:
distance=10km=10*1000=10000m
time=5min=5*60=300sec
average speed=distance/time
= 10000/300=33.33m/s
