Answer: The temperature of the air affects the speed of sound in the due to the fact that colder contains air molecules with low kinetic energy. For warm air the kinetic energy of the molecules is high causing them to move in rapid motion. Because of these vibrations and collisions sound waves moves in a faster rate.

Answer:
option A
Explanation:
The meteor shower is the celestial activity in which meteors are observed to radiate or originate from one point.
Meteors are nothing but dust or ice from the trails of comets. Most of the meteors are less than the size of the sand particle.
We will see comet shower when we earth will cross the orbit of the comet.
Hence, the correct answer is option A
Answer:
Average acceleration, 
Explanation:
Given that,
Initial velocity, u = 0 km/h
Final velocity, v = 100 km/h = 27.77 m/s
Time, t = 10 s
We need to find the average acceleration of the vehicle. It is given by the change in velocity divided by time. Som,
So, its average acceleration is 
.
No, you can't see the equator.
