Answer:
38.75 L
Explanation:
From the question,
Applying Boyles Law,
PV = P'V'....................... Equation 1
Where P = Original pressure of the Argon gas, V = Original Volume of Argon gas, P' = Final pressure of Argon gas, V' = Final Volume of Argon gas.
make V the subject of the equation
V = P'V'/P.................... Equation 2
Given: P = 34.6 atm, V' = 456 L, P' = 2.94 atm.
Substitute these values into equation 2
V = (456×2.94)/34.6
V = 38.75 L
Answer: Cotyledons are the first leaves to emerge from the soil when a plant germinates. Because they are part of the seed's embryo, they also are known as seed leaves, and provide nutrients to the seedling until its true leaves unfurl and begin the process of photosynthesis.
Explanation:
<span>The glycine molecules can bind together and release a molecule of water by the process of condensation. Water would then be considered a by-product of the reaction. Condensation can also be seen when water in the air touches a container filled with cold liquid and you see water drops on the side of the glass.</span>
Answer:
1)
2) The dependent variable = The time it takes for one pendulum swing
3) The independent variable = The length of the pendulum string with weight at the bottom
Explanation:
The relationship between the length of the pendulum string and the time it takes for one pendulum swing is giving as follows;
Where;
T = The period of oscillation = The time to complete one oscillation =Two swings of the pendulum
L = The length of the pendulum
g = The acceleration due to gravity
Therefore, the time it takes for one pendulum swing is directly proportional to the square root of the length of the pendulum
The dependent variable = The time it takes for one pendulum swing
Th independent variable = The length of the pendulum string with weight at the bottom.
Answer:
The correct answer is marsh.
Explanation:
A kind of wetland that generally gets formed in the transition regions between the aquatic and the terrestrial ecosystems is termed as the marsh. Different kinds of birds and animals are found within a marshland, and various herbaceous species like reeds and grasses are found in the marshy regions.
The formation of marshes generally takes place close to the streams or lakes, and as all the mentioned characteristics resemble the wetland pictured by Samantha in the given question, thus, the kind of wetland in which Samantha was most likely in is marsh.
