Rise in altitude is directly proportional to decrease in pressure
The earth's atmosphere has its own pressure known as atmospheric pressure.The pressure level is highest right at the surface of the earth because the air at this level is supporting the weight of all the air above it. More weight above means a greater downward gravitational force. As we move up through levels of the atmosphere, the air has less air mass above it and gravity isn’t strong enough to pull down a greater number of particles. So the balancing pressure decreases. This is why atmospheric pressure drops as we rise in altitude.
Answer:
Electromagnetic waves travel in a vacuum with a definite and unchanging speed.
When electromagnetic waves travel in vacuum, there is a definite, constant ratio between the magnitudes of the electric and magnetic fields.
Explanation:
Electromagnetic waves are waves that come about due to the vibrations generated between an electric field and a magnetic field. There is presence of oscillating magnetic and electric fields and the two statements mentioned above best describes it's properties.
Answer:
Since there is only one path for the charges to flow through, the current is the same through each resistor. The equivalent resistance of a set of resistors in a series connection is equal to the algebraic sum of the individual resistances.
speed of light in medium is 199,861.6 km/s
A as the radiant from the object heats it up its kinda like thermal heat in a way
