Do you think an observer on another planet in the solar system might see eclipses

Physics

artcher [175]3 years ago

Answer:

Yes

Explanation:

Eclipses: Eclipses are also known as game of shadows where one object comes between the star(light source) and another object in a straight line such that the shadow of one object falls on other object. This can occur when the apparent size of the star and the object is almost same.

Talking about the Earth, the geometry is such that the Moon and the Sun are of same apparent size as seen from the Earth. Thus Lunar and Solar eclipse can be seen from the Earth. If we were to go on any other planet the same phenomenon can be seen provided the apparent size of moon and the Sun from that planet is same.

We have seen and recorded many such eclipses on Jupiter. These are from the perspective of Earth. When the moons of Jupiter comes exactly between the Sun and Jupiter the shadow of moon will fall on Jupiter. The places where the shadow falls, one will see a solar eclipse.

A person hears sound wave beast at 3000Hz at the temperature of 30 °C. What is the person's ear canal length? Please explain
Evgen [1.6K]

Answer:

The person's ear canal length is 2.91 cm.

Explanation:

Given that,

Frequency = 3000 Hz

Temperature = 30°C

We need to calculate the speed

Using equation of sound wave with temperature

[texs]v(t)=331+0.6\times T[/tex]

Put the value of T

v(t)=331+0.6\times30^{\circ}\ C

v(t)=349\ m/s

We need to calculate the length

Using formula of closed organ pipe

f=\dfrac{v}{4L}

L=\dfrac{v}{4f}

Where, L = length

v = velocity

f = frequency

Put the value into the formula

L=\dfrac{349}{4\times3000}

L=0.0291\ m

L=2.91\times10^{-2}\ m

L=2.91\ cm

Hence, The person's ear canal length is 2.91 cm.

A clear sheet of polaroid is placed on top of a similar sheet so that their polarizing axes make an angle of 30° with each other
xxMikexx [17]

Answer:

\dfrac{I}{I_0}=\dfrac{3}{8}

Explanation:

Given that

Angle ,θ = 30°

From Malus law,Intensity given as

I=\dfrac{I_0}{2}cos^2\theta

Io=Intensity of unpolarized light

I=Intensity of emerging light

Now by putting the value of angle

I=\dfrac{I_0}{2}cos^2\theta

I=\dfrac{I_0}{2}cos^230^{\circ}

We know that

cos30^{\circ}=\dfrac{\sqrt{3}}{2}

I=\dfrac{I_0}{2}\times \dfrac{3}{4}

\dfrac{I}{I_0}=\dfrac{3}{8}

Therefore ratio will be \dfrac{3}{8}
