What 4 types of evidence do we use to construct the tree? Evidence for building trees DNA and RNA sequences (as well as other molecular traits like the amino acid sequences of proteins). Morphology (i.e., structure and form). What is a branching tree diagram? A branching tree diagram is a set of groups within groups, […]
Can you replace argon gas in Windows?
Can you replace argon gas in Windows? Yes. If you send out a window professional for an inspection, he or she can gauge the current level of argon gas in your double-pane windows. If a substantial amount has been lost then there is a method to replace the gas between the panes of glass. However, […]
What does the Boltzmann equation describe?
What does the Boltzmann equation describe? 1 The Boltzmann equation. The Boltzmann equation describes the evolution of the particle density of a rarefied gas. Indeed, the molecules of a gas can be modeled by hard spheres that move according to the laws of classical mechanics. How is Boltzmann ratio calculated? P = 1/Z * exp(- […]
What two factors determine the strength of the force of gravity between two objects?
What two factors determine the strength of the force of gravity between two objects? Newton’s law also states that the strength of gravity between any two objects depends on two factors: the masses of the objects and the distance between them. Objects with greater mass have a stronger force of gravity between them. Objects that […]

What are 5 reasons physical education is important?
What are 5 reasons physical education is important? Here are five reasons why physical education is an essential part of a well-rounded education: It Encourages Healthy Habits. First let’s state the obvious: kids who get daily exercise are healthier. It Reduces Stress. It Encourages Prosocial Behavior. It Promotes Good Sleep. It Helps Students Concentrate. Why […]
Is Focal length inversely proportional to refractive index?
Is Focal length inversely proportional to refractive index? From this formula we can say that focal length of lens is inversely proportional to refractive index of material of lens medium. i.e As Refractive index (m) increases focal length (f) of lens decreases. What is the relation between focal length and radius of curvature? The relation […]
What would happen if something hit Earth at the speed of light?
Can isolated system be closed system?
Can isolated system be closed system? There can be mass transfers as well as energy transfers across the boundary. Isolated systems: An isolated system is special type of closed system that does not even transfer energy across the boundary. There will be no interactions with the surroundings. What is meant by a closed system? A […]
What has size shape but no weight?
What has size shape but no weight? Anything in zero-gravity can have a certain size, shape but will be weightless. Explanation: The weight of a person or an object is actually a force. What takes the size and shape of any container? A liquid takes a shape of the container because particles in a liquid […]
