A Light year is

A
Light emitted by the Sun in one year.

B
Time taken by light to travel from Sun to Earth.

C
The distance travelled by light in one year.

D
Time taken by Earth to go once around the Sun.

Solution

1 light year $$=$$ speed of light in vacuum $$\times$$ no. of seconds in one year
$$1\ LY =(3\times 10^8)\times (365\times 24\times 60\times 60)=9.467\times 10^{15}\ m$$
A light-year is defined as the distance traveled by light in a vacuum in one year.
Question 3
1 / -0

Which of the following units is used to measure distance between the stars?

A
$$km$$

B
$$m$$

C
$$light\ year$$

D
$$fm$$

Solution

$$Light\ year$$ is an unit in astronomy to measure distances between the stars. A light year distance travelled by light in vacuum in one year which is equal to $$1\ light\ year = 9.46 \times 10^{15}\ m$$.
Question 4

Morning star is the name given to

A
pole star

B
star Sirius

C
planet Jupiter

The plane, in which the Earth revolves around the Sun, is called _______ plane of Sun.

A
equatorial

B
tangential

C
normal

D
orbital

Solution

Question 7
1 / -0

The planets keep changing their position with respect to:

A
Galaxy

B
Stars

C
Venus

D
Moon

Solution

Planets are solid heavenly bodies that revolve around the Sun in closed elliptical paths. A planet is made of rock and metal and produces no light of its own. A planet shines because it reflects the light of the Sun. Since the planets are much nearer to the stars, they appear to be big and do not twinkle at night. The planets move around the Sun from West to East, so the relative positions of the planets keep changing day by day. They are very small compared to the sun and other stars.
Hence, the star appears to remain in a fixed position with respect to each other whereas the distance between the planets keeps changing constantly.
Question 8
1 / -0

Light year is the unit of

A
distance

B
time

C
speed

D
mass

Solution

Light year is the distance travelled by light in vacuum in one year.
One light year $$=9.467\times 10^{15}\ m$$
