Pressure exerted by means of an Earth's atmosphere.

<u>Explanation:</u>

Atmospheric pressure is also termed as barometric pressure, that is the pressure exist in the Earth's atmosphere, in other words it is the pressure wielded by the atmosphere's weight.

1 atmosphere = 760 mm Hg

Atmospheric pressure could be measured using the equation,

Atmospheric pressure = Mercury's density × acceleration through gravity × the height of mercury column.

It can be measured or given in terms of Pa, torr. atm, psi, mm Hg and so on.

A plane accelerates from rest at a constant rate of 5.00 m/s2 along a runway that is 1800 m long. Assume that the plane reaches

tiny-mole [99]

Answer:

26.8 seconds

Explanation:

To solve this problem we have to use 2 kinematics equations: *I can't use subscripts for some reason on here so I am going to use these variables:

v = final velocity

z = initial velocity

x = distance

t = time

a = acceleration

${v}^{2} = {z}^{2} + 2ax$

$v = z + at$

First let's find the final velocity the plane will have at the end of the runway using the first equation:

${v}^{2} = {0}^{2} + 2(5)(1800)$

$v = 60 \sqrt{5}$

Now we can plug this into the second equation to find t:

$60 \sqrt{5} = 0 + 5t$

$t = 12 \sqrt{5}$

Then using 3 significant figures we round to 26.8 seconds

________ capture solar energy and use photosynthesis to produce sugars.

vovikov84 [41]

Answer:

Option (A)

Explanation:

The green plants are capable of synthesizing their own food, in the presence of sunlight, CO₂ and water, and in return, liberates food and oxygen (O₂). This process is known as photosynthesis. This process is possible due to the presence of chlorophyll pigments on the plant leaves.

These green plants are also known as producers, because they are able to generate food for the consumers.

Thus, the correct answer is option (A).

The electrons lost from chlorophyll photooxidation are replaced by the oxidation of water. how many electrons are generated from

White raven [17]

There are 2 electrons generated from the oxidation of one water molecule.

<h3>Describe photooxidation.</h3>

The process of a substance interacting with oxygen or losing electrons from chemical species under the influence of light is known as photooxidation. Photooxidation happens in plants when there is environmental stress. It is called photooxidative stress as a result. Reactive oxygen species are produced by the absorption of excess excitation energy in plant tissues. Chloroplasts are harmed by the accumulation of these reactive oxygen species, which is a damaging process in plants. High-intensity light and little $CO_{2}$ are the two conditions that cause this photooxidative stress to occur most frequently. It is a procedure that requires light. Photorespiration in $C_{3}$ plants guards against photooxidation.
