Answer:
Air is a mixture of gases. Gas is a state of matter. Hence, air is matter.
Explanation:
See the attached file. It contains a table explaining the composition of air.
At Z ... slowest speed
At Y ... fastest speed
At X ... medium speed
Wherever it is in its orbit, the line from the planet to the Sun smears over the same amount of area every second.
That's Kepler's second law of planetary motion.
The reason this happens is: That's how gravity works. (A better explanation is available, but first you have to be able to twirl calculus and solid geometry in the air on long sticks.)
Answer:
Are you looking for the formula? because if so:
M L^2 T^-3 I^-2
Explanation:
May I have brainliest please? :)
It is wrong to say heat because if yuo want to be scientific then it is energy
Answer:
option a
Explanation:
Light is an electromagnetic wave which can travel in vacuum as well as any medium. The speed of light is maximum in vacuum. The electromagnetic wave travels by oscillating electric and magnetic field to the direction of motion of wave.
On the other hand, sound waves are mechanical waves which can only travel in a medium as they can only move forward by oscillating material particles.
Thus, the student should conclude option a.
