Answer:

Energy or calorific flow.

Explanation:

Energy flow, which is also called the calorific flow, is defined as the flow of energy through an ecosystems food chain. It is the focus of study in ecological energetics and also how energy is converted from one form to another in an ecosystem.

Example of a typical energy flow: Solar energy is fixed by the photoautotrophs, called primary producers, like green plants which uses the energy for photosynthesis.

__________ research is designed to measure the association between variables that are not manipulated by the researcher.

Sliva [168]

Answer:

Option c. Correlational

Explanation:

Correlational research is basically a method of carrying out a research where an experiment can not be conducted and where a researcher has to figure out that whether the two variable are in association with each other and if these are related then in what way the association between these two exists without any manipulation from the researcher's end.

It seeks to understand, measure and make assessment of the relationship or

association between these variables but can not find out if a variable is caused by the other variable.

Len [333]

Answer: TRUE

Explanation:

Atoms are happy when they will not react with other elements while having a full outside ring of electrons because this makes them to be noble.

A stable atom possesses full outside ring of electrons while unstable one does not. So, they are happy also because of stability.

Answer:

You are asked to design a cylindrical steel rod 50.0 cm long, with a circular cross section, that will conduct 170.0 J/s from a furnace at 350.0 ∘C to a container of boiling water under 1 atmosphere.

Explanation:

Given Values:

L = 50 cm = 0.5 m

H = 170 j/s

To find the diameter of the rod, we have to find the area of the rod using the following formula.

Here Tc = 100.0° C

k = 50.2

H = k × A × $\frac{[T_{H -}T_{C} ] }{L}$
