Answer:
plants
animals
Explanation:
From the given choices only plants and animals are biotic in nature. Biotic factors are factors that can be attributed to living organisms.
The other choices such as water, light and minerals are abiotic. They are do not originate from living organisms.
Both biotic and abiotic factors are present within the ecosystem. In fact, they influence the ecosystem to a very large extent.
Together, these factors shapes the ecosystem.
Answer:
Explanation:
The gas ideal law is
PV= nRT (equation 1)
Where:
P = pressure
R = gas constant
T = temperature
n= moles of substance
V = volume
Working with equation 1 we can get
The number of moles is mass (m) / molecular weight (mw). Replacing this value in the equation we get.
or
(equation 2)
The cylindrical container has a constant pressure p
The volume is the volume of a cylinder this is
Where:
r = radius
h = height
(pi) = number pi (3.1415)
This cylinder has a radius, r and height, h so the volume is
Since the temperatures has linear distribution, we can say that the temperature in the cylinder is the average between the temperature in the top and in the bottom of the cylinder. This is:
Replacing these values in the equation 2 we get:
(equation 2)
Answer:
The light bulb converts electrical energy into light and <u>heat energy</u>
Answer:
Mixture
Explanation:
It is made up of just one type of element (sulfer). Since multiple elements are joined together, it's an example of a mixture.
