sashaice [31]3 years ago
4 0

Answer:

\$100,000

Explanation:

<em>The top 5 winners of NASA's design contest winner received amount of  </em>\$100,000<em> </em>(Dollar One hundred thousand)<em>. </em>The respected amount was divided into 5 parts as there were 5 winners as well.

So, the amount was divided among the winners are as follows:

<em>Winner 1 ⇒ </em>\$20,957.95

<em>Winner 2 ⇒ </em>\$20,957.24

<em>Winner 3 ⇒ </em>\$20,622.74

<em>Winner 4 ⇒ </em>\$19,580.97

<em>Winner 5 ⇒</em> \$17,881.10

Hence by adding all of the 5, we will get the answer, which is \$100,000.

Four hundred seventy joules of heat are removed from a heat reservoir at a temperature of 470 K. What is the entropy change of t
11111nata11111 [884]

Answer:

ΔS= -1 J/K

Explanation:

Given data

Heat Q= -470J

Temperature T=470 K

To find

Entropy change ΔS

Solution

We know that the entropy change of system is ΔS is given by

ΔS=Q/T

We have take heat value Q as negative because the heat is removed from heat reservoir

So

ΔS=(-470J/470K)

ΔS= -1 J/K

Multiple-Concept Example 7 and Interactive LearningWare 26.1 provide some helpful background for this problem. The drawing shows
Vlada [557]

Answer:

n = 1.4266

Explanation:

Given that:

refractive index of crystalline slab n = 1.665

let refractive index of fluid is n.

angle of incidence θ₁ = 37.0°

Critical angle \theta _c = sin^{-1} (\frac{n}{n_{slab}} )

sin \theta _ c =\frac{n}{n_{slab}}

According to Snell's law of refraction:

n sin \theta _1 = n_{slab}  \ sin \  (90- \theta_c)

At point P ; 90 - \theta _2  \leq \theta _c

\theta _2 = 90 - \theta _c

Therefore:

n \ sin \theta_1 = n_{slab} \sqrt{(1-sin^2 \theta _c)}  \\ \\ n \ sin \theta_1 = n_{slab}   \sqrt{(1- \frac{n}{n_{slab}} )}

Then maximum value of refractive index  n of the fluid is:

n = \frac{n_{slab}}{\sqrt{1+ sin^2 \theta _1 } }

n = \frac{1.665}{\sqrt{1+ sin^2 \  37} }

n = 1.4266
