It is so because the steel is more colder than our body.
If electromagnetic radiation acted like particles in the double-slit experiment, we would observe one bright band would appear in the center of the screen.
<h3>Bahavior of particles in double-slit experiment</h3>
In a double-slit experiment, single particles, such as photons, pass one at a time through a screen containing two slits.
The photons behave like wave and the constructive interfernce of the waves of these photons will generate a high amplitude wave seen as a bright band in the center of the screen.
Thus, if electromagnetic radiation acted like particles in the double-slit experiment, we would observe one bright band would appear in the center of the screen.

Answer
given,
Q u = 8.7 m³/s
Q d= 0.9 m³/s
BOD concentration = 50 mg/L
a) BOD concentration at the down stream


= 4.69 mg/L
b) discharge = 9.6 m³/s
cross sectional area = 10 m²
velocity steam = 
= 0.96 m/s
time taken to move 50 km down stream =
= 52083.3 s
= 
= 0.6 days
now,



Answer:
Constructed cladograms all typically share certain key features: Root – The initial ancestor common to all organisms within the cladogram (incoming line shows it originates from a larger clade) Nodes – Each node corresponds to a hypothetical common ancestor that speciated to give rise to two (or more) daughter taxa.
