Answer: have liquid water

Explanation:

Liquid water and atmosphere are important for life to exist on a planet. Life can exist in the form of unicellular. It must not be multi-cellular organisms like animals.  A cell is majorly composed of water. Thus, liquid water is very essential for life to exist. All the life processes require liquid water. Thus, astronomers focus especially on finding planets that have liquid water.

The length of daylight on the moon is about __________.
Lyrx [107]
<span>The length of daylight on the moon is about 29.5 days.</span>

From the earliest days, the Moon has been there in the Solar System and there has never been a period when we couldn't gaze upward in the night sky and either observe the Moon hanging there, or realize that it would be back the precise one night from now (i.e. a New Moon).

 A day on the Moon keeps going as long as 29.5 Earth days. We can say that it would take 29.5 days for the Sun to move the distance over the sky and come back to its unique position once more.

Y_Kistochka [10]

Complete question is;

A bicycle and a car start their journey at the same time the cyclist reaches it's top speed of 10m/s in 15 s, the car reaches a speed of 15 m/s in 55 s. which has the greater acceleration the car or the bicycle.

Answer:

The bicycle has the greater acceleration.

Explanation:

Cyclist reaches a top speed of 10m/s in 15 s.

Formula for acceleration here is;

a = v/t

a = 10/15

a = 0.67 m/s²

Car reaches a speed of 15 m/s in 55 s.

Thus;

a = 15/55

a = 0.27 m/s²

From the 2 acceleration values gotten, we can say that;

The bicycle has the greater acceleration.
