Question 7 options:
Their speeds are the same.
the object with the greater speed has greater kinetic energy
the object greater speed has the lower kinetic energy
the object with the smaller mass has the greater kinetic energy
Answer: Option (B) is the correct answer.
Explanation:
Kinetic energy is the energy due to the motion of an object.
Mathematically, K.E =
where m = mass
v = velocity
Therefore, an object whose velocity is more will have more kinetic energy.
Thus, we can conclude that out of the given options, the object with the greater speed has greater kinetic energy is true about their kinetic energy.
Answer:
more stable
Explanation:
In terms of ecological succession, a community tends to become more stable over time.
As an ecosystem changes over time, species best adapted to that habitat tend to replace other, lesser adapted species until an equilibrium is reached. When drastic changes in the numbers and types of species cease to occur, the community has reached a climax state.
Your answer is strontium
A.
Heat always flows from cooler objects to warmer objects.
B.
Heat always flows from warmer objects to cooler objects.
C.
Heat never travels in a similar pattern.
D.
Heat never transfers from solids to liquids.
A particle diagram showing the composition of air would represent various gases like nitrogen, oxygen, water vapor, and carbon dioxide as spheres of different colors. The proportions between these gases would be shown by having a majority of nitrogen and oxygen spheres as they make up most of our atmosphere. The diagram may also include symbols for dust particles and particulate matter.
A particle diagram to illustrate the composition of air would visually represent the mixture of gases that comprise our atmosphere. Primarily, the atmospheric mix includes nitrogen (N₂; 78.6 percent), oxygen (O₂; 20.9 percent), water vapor (H₂O; 0.5 percent), and carbon dioxide (CO₂; 0.04 percent).
Each of these gases exist as molecules, with nitrogen and oxygen being diatomic. In other words, their molecules consist of two atoms.
In such a diagram, each type of atom would be represented as a sphere of a different color, for instance, nitrogen atoms might be blue, oxygen red, hydrogen white, and carbon grey.
The proportions would be represented by having a larger number of nitrogen and oxygen spheres compared to water vapor and carbon dioxide.
Furthermore, there might be additional entities in the diagram to represent dust particles or other environmental particulate matter suspended in the air. This allows us to get a qualitative understanding of the composition of Earth's atmosphere and mechanisms that drive gas exchange.
