Explanation :

The phenomena in which the ray of light bend towards or away from the normal is called the refraction of light. Light always travels in straight line. If the speed of light in both medium differs then refraction occurs.

According to Snell's law :

$\dfrac{sin\ \theta_1}{sin\ \theta_2}=\dfrac{v_1}{v_2}=\dfrac{n_2}{n_1}$

Where $n_1$ and $n_2$ is the refractive indices of two medium 1 and medium 2.

$v_1$ and $v_2$ is the speed of light in medium 1 and medium 2.

Hence, the given figure shows the refraction of light.

At what wavelength does Io reflect the most sunlight? A. Blue

sineoko [7]

Answer:

B. Ultraviolet.

Explanation:

Io is the fourth smallest moon in the Galilean moons and it is the innermost moon out of the other three moon. It has the highest density as compare to the moon and it has lowest water at its surface.

While it is Jupiter moon it leaves a footprint of magnet over the Jupiter's upper atmosphere. The appearance of this moon look like as a spot of ultraviolet emission that remains fixed underneath Io as Jupiter rotates. So it reflects Ultraviolet radiations.

If the slowest instruction in the SCA executes in 12.5 ns, then what is maximum system clock frequency in MHz

Margaret [11]

Since the slowest instruction in the SCA executes in 12.5 ns, the maximum system clock frequency is 80 MHz

To answer the question, we need to know what frequency is.

<h3>What is frequency?</h3>

Frequency is the number of oscillations per second of a wave.

It is given by f = 1/T where T = period of wave

Now, given that the slowest instruction in the SCA executes in t = 12.5 ns, we need to calculate maximum system clock frequency, f.

<h3>What is the maximum system clock frequency?</h3>

So, f = 1/t

= 1/12.5 ns

= 1/(12.5 × 10⁻⁹ s)

= 1/12.5 × 10⁹ Hz

= 0.08 × 10⁹ Hz

= 80 × 10⁻³ × 10⁹ Hz

= 80 × 10⁶ Hz

= 80 MHz

So, the maximum system clock frequency is 80 MHz

Efficiency of a machine is always less than 100% why?

kifflom [539]

The reason the efficiency is always less than 100% is because there is always some sort of friction in the machine.

Answer: because of friction

A spherical shell has an outside radius of 2.60 cm and an inside radius of a. The shell wall has uniform thickness and is made o

lbvjy [14]

Answer:

The answer is below

Explanation:

a) The volume of a sphere is:

Volume = (4/3)πr³; where r is the radius of the shell.

Given the outside radius of 2.60 cm and inner radius of a cm, the volume of the spherical shell is:

Volume of spherical shell = $\frac{4}{3} \pi (2.6^3-a^3)$ cm³

But Density = mass / volume; Mass = density * volume.

Therefore, mass of spherical shell = density * volume

mass of spherical shell = $4.70\ g/cm^3$ * $\frac{4}{3} \pi (2.6^3-a^3)$ cm³

Mass of liquid = volume of inner shell * density of liquid

Mass of liquid = $\frac{4}{3} \pi a^3\ cm^3*1.23\ g/cm^3$

Total mass of sphere including contents = mass of spherical shell + mass of liquid

Total mass of sphere including contents (M) = $4.70\ g/cm^3$ * $\frac{4}{3} \pi (2.6^3-a^3)\ cm^3$ + $\frac{4}{3} \pi a^3\ cm^3*1.23\ g/cm^3$ =

Total mass of sphere including contents (M) = (346 - 14.5a³) grams

b) The mass is maximum when the value of a = 0

M = 346 - 14.5a³

M' = 43.5a² = 0

43.5a² = 0

a = 0

Like the moon's orbit, Earth's orbit is not a perfect circle, but an oval How do you think this might affect Earth's tides?

ExtremeBDS [4]

During the parts in the orbit where the moon is farthest away from the earth the tides will be low. Whereas during the parts where the moon is closer to the earth the tides will be higher.

Good Luck!
