What will the angle of refraction be for a ray of light passing from air into a sodium chloride crystal if the angle of incidenc
wlad13 [49]

Answer:

<h2> The refracted angle is r= 34.47°</h2>

Explanation:

According to snell's law the incident normal and refracted ray at the point of incidence all lie in the same plane

Given

incident angle i= 60°

refracted angle r= ?

index of refraction u= 1.53.

Applying the formula

u= \frac{sine (i)}{sine( r)}

solving for r

1.53=\frac{ sine (60)}{ sine( r)}\\\1.53= \frac{0.866}{ sine( r)} \\\ sine( r)= \frac{0.866}{1.53} \\\sine(r)= 0.566\\\r= sine^-0.566\\\r= 34.47

r= 34.47°

A variação no comprimento de uma barra de alumínio foi de 0,0002m. Calcular a variação na temperatura a =22x10-⁶
Furkat [3]

Answer:

1.82°C

Explanation:

presumir inicial comprimento = l₀ = 5 m

dado que:

coeficiente de expansão (α) = 22 x 10⁻⁶, A variação no comprimento (ΔL) = 0.0002 m,

inicial comprimento = l₀ = 5 m

variação na temperatura = ΔT

para Calcular a variação na temperatura,  nós usamos a fórmula:

\Delta L=l_0\alpha \Delta T

substituindo valores:

0.0002=5*22*10^{-6}\Delta T\\\Delta T=\frac{0.0002}{5*22*10^{-6}}\\ 5*22*10^{-6}=1.82^0C

variação na temperatura = 1.82°C

Explain how low atmospheric oxygen slowed alligator growth in terms of cellular respiration.
sveta [45]

Answer:

Explanation:

The quantity of oxygen in the atmosphere influences the development trajectory, cardiovascular allometry, and metabolic rate of the American alligator. The growth of hypoxic alligators is hampered by a lack of oxygen in the atmosphere, which may impair their food use capabilities.

Which action would increase the strength of the electric force between the ballon and the water
OLga [1]

Complete question is;

Which action would increase the strength of the electric force between the balloon and the water?

A. Holding a magnet near the stream of water

B. Holding the balloon closer to the stream of water

C. Holding a magnet near the balloon

D. Moving the balloon farther away from the stream of water

Answer:

B. Holding the balloon closer to the stream of water

Explanation:

When we take a charged balloon near water, what happens is that it makes electrons to be pushed away which in turn leaves the area to be positively charged. This area is now attracted to the balloon and thus the strength of the electric force between the balloon and the water is increased.
