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:
Area=1.5(1.5)=2.25m^2
Force of gravity=10N
\begin{gathered}\\ \sf\longmapsto Pressure=\dfrac{Force}{Area}\end{gathered}
⟼Pressure=
Area
Force
\begin{gathered}\\ \sf\longmapsto Pressure=\dfrac{10}{2.25}\end{gathered}
⟼Pressure=

\begin{gathered}\\ \sf\longmapsto Pressure=4.4Pa\end{gathered}
⟼Pressure=4.4Pa
The series circuit is the one in which the current flowing through each bulb will be the same as the current at point x.
<h3>What is a series circuit?</h3>
When bulbs are connected in series, the bulbs are connected in an end to end manner. The same current flows through all the bulbs when they are connected in series.
As such, the series circuit is the one in which the current flowing through each bulb will be the same as the current at point x.

The correct answer is amplify each other
If they move at the same speed with the same frequency in the the same direction, then they will amplify each other due to constructive interference.
Answer:
Explanation:
<u>Functions</u>
When one magnitude depends on other (or others), we usually try to express them as a function which can contain any number of variables, constants, and operations.
The area of a circle is computed by the well-known formula
We are required to use function notation to express the area of a circle f(r) in terms of the radius r. If the radius is in cm, then the area is in .
The required function is
For a radius of 4.3 cm:
