Distance measurements based on the speed of light; used for objects in space

Answers

Answer 1

Answer:

Answer : Yes, distance measurements based on the speed of light used for objects in space.

Explanation : A light year is measurement of distance that light travel in a one year.

In a one year light travels 9460000000000 kilometer.

We know that, speed of light is $3*10^(8)\ m/s$

and time is 31536000 seconds in 1 year

so, distance= speed of light X time

Now, the light year is $9.4608*10^(15) meter$

Example : The nearest star to earth is about 4.3 light year away.

Which currents carry warm water away from the equator?a. deep currents
c. surface currents
b. evaporation
d. freezing Please select the best answer from the choices provided A B C D

Answers

Answer:

Surface currents

Explanation:

The water at the ocean surface is moved by the winds which blows in certain pattern due to earth spin and Coriolis effect.wind is able to move top layer of ocean up to 400 m creating surface ocean current.

Ocean current carry warmth of water to higher Latitudes thus making the climate of that region less chilly.

the answer is
c. surface currents
