Answer:
When an object experiences a net force, it will accelerate at a rate determined by its mass
Explanation:
A body at rest is considered to have a zero speed, so any force causing the body to move is an unbalanced force and any force causing the body to slow down is also an unbalanced force. An unbalanced force cause acceleration or deceleration i.e a change in speed
An astronomical unit (AU) is the approximate distance from the earth to the sun. The answer is D.
Answer: C is the right answer because the wind can cool off
The owl is a generalists creature/species because it is able to thrive in a wide variety of environmental conditions and can make use of a variety of different resources (for example, a heterotroph with a varied diet). A specialist species can only thrive in a narrow range of environmental conditions or has a limited diet. Most organisms do not all fit neatly into either group, however. Some species are highly specialized (the most extreme case being monophagy), others less so, while some can tolerate many different environments. In other words, there is a continuum from highly specialized to broadly generalist species.
Answer:
Explanation:
The pH scale stands for the power or potential of hydrogen. It measures how acidic or basic a solution based on the concentration of hydrogen ions and a scale from 1 to 14.
This scale is unique because it is logarithmic. So, every time the pH changes by 1 on the scale, the actual concentration of the solution increases or decreases by a tenfold.
So, a solution with a pH of 7 is ten times more acidic than a solution with a pH of 8. This can be translated to:
The black coffee has a pH of 5 and the hand soap has a pH of 10. We want to find how many times more acidic coffee is, so we subtract 5 from 10 and get 5. The difference in pH is 5.
Coffee is <u>10⁵ or 100,000 times more acidic than hand soap.</u>
