Explanation:
The answer for this question depends on the type of meniscus in the cylinder. If it is an upright meniscus like in water, the reading should be taken at the bottom of the meniscus. However if it is an inverted meniscus like in mercury, the reading should be taken at the top of the meniscus.

Answer:
177.993 MeV
Explanation:
Nuclear fission refers to a process where a nucleus is broken into smaller ones.
m(Am) = 242.0595490 u, m(Sr) = 89.9077387 u, m(La) = 148.934733 u and m(n) = 1.008665 u. To find the mass of X, we sum up the masses on both side and subtract them according to the equation given
242 + X = 90 +149 + 4
X = 243 - 242 = 1
so X is a neutron
next we calculate the Δm ( change in mass)
Δm = mass reactant - mass of product
(242.0595490 + 1.008665 ) - ( 89.9077387 + 148.934733 + 4 (1.008665))
= 243.068214 - 242.8771317 = 0.1910823 u
using the formula
E = (Δm) c² = 0.1910823 u × c² × 
× 
= 177.993 MeV

Answer:
Sugar, Carbon Dioxide, And Water
Explanation:
A chemical substance is a form of matter having constant chemical composition and characteristic properties. Some references add that chemical substance cannot be separated into its constituent elements by physical separation methods, i.e., without breaking chemical bonds. Chemical substances can be simple substances, chemical compounds, or alloys. Chemical elements may or may not be included in the definition, depending on expert viewpoint.
Answer and Explanation:
Temperature: The ideal temperature for photosynthesis to be performed is 35ºC. This is because this is the ideal temperature range for which enzymes related to photosynthesis can act, and these enzymes can be denatured at higher or lower temperatures and denatured enzymes do not work properly.
Light intensity: Chlorophyll better absorbs the light intensity in the lengths of 450-475 nm and 650-675 nm. These intensities present the blue and orange red spectra.
CO2 levels: The ideal CO2 limit for performing photosynthesis is 0.3%. Above this limit the photosynthetic process can have harmful changes.
Oxygen production: Ideally, photosynthesis will release an oxygen molecule into the atmosphere, from each water molecule that the plant has absorbed.
