Answer:
212 degrees F, and 100 degrees C.
Explanation:
If the temperature is held constant (which requires some heat input, since evaporation cools things) the liquid will all evaporate. If the temperature is much above 212 F, the water will boil. That means that it wont just evaporate from the surface but will form vapor bubbles, which then grow, inside the liquid itself. :)
Answer:
a. Interference patterns are observed when a wave passes through a barrier with two slits
Explanation:
Interference is a situation where two waves superimpose to form a new wave of a different amplitude. This amplitude can be greater, same or lower.
the diagram attached below shows the movement of a wave through a barrier with two slits.
you can notice the portions of the wave that overlap. This overlapping of waves is the interference.
Thus, option A is correct.
The other options however, are not correct. as shown below:
Option B is wrong as waves exhibit diffraction <em>(it is diffraction of the light wave that produces the rainbows we see in the sky)</em>
Option C is wrong as waves do not travel straight through slits always.
Option D is wrong as waves can also interfere constructively and destructively.
Density = Mass / Volume
Input the values in their respective places and then use algebra to solve for volume.
Hope that helps.
Answer:
The element carbon is a part of seawater, the atmosphere, rocks such as limestone and coal, soils, as well as all living things. ... When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground. Some is buried and will become fossil fuels in millions and millions of years.
Explanation:
<span>Solving for the percent composition by mass of sulfur. The formula would be:
%S = mass of sulfur / mass of compound x 100%
Plugging in our data:
%S = 32 amu / 120 amu x 100%
%S = 0.266666 x 100%
%S = 26.66%
Rounded off to two significant numbers it will be 27%. Therefore the answer is number 2.</span>
