Answer:
P = 375 Pa
Explanation:
The question says that,"If a force of 150N was applied in an area of 0.4m², what will be the precious exerted?"
We have,
Force, F = 150 N
Area, A = 0.4m²
We need to find the pressure exerted. We know that,
Pressure = forece/area
So,
So, the required pressure is equal to 375 pa.
Answer:
When the northern hemisphere experiences autumn, the southern hemisphere experiences <u><em>spring</em></u>
Explanation:
When the northern hemisphere experiences autumn, the southern hemisphere experiences <u><em>spring</em></u>
This is due to the equinoxes. An equinox is an event that occurs twice a year. During these seasons all areas of the Earth's surface experience an equal amount of daylight and darkness. The sun is on the equator line, so the day and night in both hemispheres have the same duration. At that time the part of the Earth closest to the Sun is the equator.
The shape of the Earth means that while the spring equinox is experienced in the northern hemisphere, the autumn equinox is entered in the southern hemisphere.
Answer:
speed of molecule ∝ 1/mass of molecule.
Explanation:
The velocities of the molecules depend on their masses. That's because if the molecules are large in size, their velocity is slower. Therefore their velocity is quicker when their size is small, since the molecules can move faster.
Therefore , it can be written as
speed of molecule ∝ 1/mass of molecule.
When condensation happens to a gas element, there will be an instance where it will suddenly turn into a liquid element. On the other hand, deposition is a process where the gas will turn into a solid element once it happens.
This is false. There were many times in history when people discovered something that they didn't even know was possible or didn't even plan to discover it. Knowing tradeoffs doesn't mean that something won't surprise you or that all will go according to plan.
