'The bottom of a pond appears raised.'<br><br>What will be the diagram of this phenomenon?​?
TiliK225 [7]

Answer:

'The bottom of a pond appears raised.' due to refraction phenomenon.

Explanation:

  • Whenever light travel through different medium it bends its path. so when the light travels into pond i.e air(rarer) to water (denser) it bends its path creating an illusion.
  • The bending of this light ( away the normal) and again towards the normal after reflecting from bottom of pond creates an vision as if the bottom of pond is raised a little.
  • This phenomenon is called as the refraction phenomenon.

PilotLPTM [1.2K]

Answer:

a)  425.6 K = 152.6 degree Celsius

b)  678.6 square centimeter

Explanation:

Initial enthalpy = Final enthalpy

m(h1 + v1^2/2) = m(h2 + v2^2/2)

(h1 + v1^2/2) = (h2 + v2^2/2)

h 2 = (h1 + v1^2/2) - (v2^2/2)

h 2 = 400.98 + (230^2 – 30^2)/2 * 10^-3

= 426.98 KJ/Kg

T2 = T1’ + (T2’ -T1’)(h2-h1’)/( h2’-h1’)

T2 = 420 + (430-420)(431.43-421.26)(426.98-421.26)/(431.43 – 421.26)

T2 = 425.6 K = 152.6 degree Celsius

Area = mRT2/P2V2

Area = (600/60*60*1) *0.287*425.6/(100*30) *10^4

Area = 678.6 square centimeter

mart [117]

Answer:

Distance from sun, orbit and rotation. Presence of interior oceans, and elements that forms compressed water.

Explanation:

  • Both the planets are Jovian planets and have layers formed by ice such as that of Uranus does not have any surface. Such as the planet is only rotating fluids.  While 80% of the mass of Neptune is made up of fluids or icy water and also consists of ammonia and methane.
