3) When the temperature of a blackbody increases from 900 K to 2300 K, by what factor does the total power of the electromagneti

LekaFEV [45]

Answer:

The electromagnetic radiation per-unit- area increase by 42.65 times.

Explanation:

The radiation per-unit- area (P) is directly proportional to the fourth power of the temperature. Thus,

P ∝ T⁴

For, when the temperature is raised from T₀ to T₁ , the radiation per-unit- area is related to as:

$\frac {P_1}{P_0}=\frac {T_1^4}{T_0^4}$

T₀ = 900 K

T₁ = 2300 K

$\frac {P_1}{P_0}=\frac {2300^4}{900^4}$

So,

P₁ = 42.65 P₀

The electromagnetic radiation per-unit- area increase by 42.65 times.

Find the value of 11° 350 yd x.yd

sweet [91]

Answer:

x = 101.1 yd

Explanation:

We are to find the value of x

Angle opposite to x = 11° (alternate angles are congruent)

Reference angle = 11°

Opposite = x

Hypotenuse = 530 yd

Apply trigonometric function, SOH, to find x.

Sin 11 = Opp/Hyp

Sin 11 = x/530

530 × Sin 11 = x

101.128767 = x

x = 101.1 yd (nearest tenth)
