Answer:
The true statement is that different gases with the same mass and temperature always have the same average kinetic energy. This is one of the postulates of the kinetic theory of matter.
If we two objects A and B, they will have mass mA and mB and velocity vA and vB respectively. If K.E = 1/2mv^2 . Then it follows that
1/2mAvA = 1/2mBvB. Since the mass is the same it means the velocity of the two objects should be the same so that they have the same average kinetic energy.
Answer:c
Explanation: Population density is a measurement of population per unit area, or exceptionally unit volume; it is a quantity of type number density. It is frequently applied to living organisms, most of the time to humans.
Answer:
A projected coordinate system is defined on a flat two-dimensional surface. Unlike a geographic coordinate system, a projected coordinate system has constant lengths, angles and areas in both dimensions.
Explanation:
Locations on earth are often expressed in geographic degrees (latitude and longitude). But when you are doing a topographic survey you need to speak in meters and feet. This is because, depending on the application, it uses a geographic or projected coordinate system.
A <u>geographic coordinate system</u> (GCS) is a coordinate system that uses a three-dimensional spherical surface (ellipsoid) to define locations on the earth. A common choice of coordinates is latitude and longitude.
In a <u>projected coordinate system</u> (PCS), you project the geographic coordinate that you have measured, for example, in a cylinder that easily unfolds over a two-dimensional surface (the map).
A topical rainforest is characterized by very tall trees which compete for light with each other. This means that the higher a layer is, the bigger chance it has for sunlight. All levels of canopy are quite high- so they still receive some sunlight.
The correct answer is the ground, which receives very little light
The answer is thunderstorm because using process of elimination, a thunderstorm is the only natural disaster that would produce lighting. By the way you put all the answers as a. Hope this helps!
