Answer:

water

Explanation:

The light energy trapped in the chlorophyll a reactive molecule of Photosystem II releases electrons at a higher energy level. These electrons are replaced in the chlorophyll a molecule by electrons that come indirectly from water molecules that are cleaved and also release protons (H +) and oxygen gas. The electrons pass from the primary electron acceptor, along an electron transport chain, at a lower energy level, the reaction center of Photosystem I. As they pass along this electron transport chain , a proton gradient is formed from which ATP is synthesized. The light energy absorbed by Photosystem I releases electrons to another primary acceptor. From this acceptor, electrons are transferred by other transporters to NADP + and NADPH is formed. The electrons removed from Photosystem I are replaced by those from Photosystem II. ATP and NADPH represent the net gain of the reactions that capture energy.

I think the answer is A) Cindy biked westward at 30km/h. I'm sorry if I'm wrong. If that's not correct then it's definitely C) A dog runs an average of 8mp/h. I hope this helps. :)

Each of the rods depicted below were machined from same stock metal. They were originally machined to be the same length, but th
Shkiper50 [21]

The force required to extend a rod increases as the cross sectional area

increases.

The rod that experiences the largest force is <u>rod B</u>

Reason:

The elongation of a rod by the application of a force is given by the

following formula;

\Delta L = \dfrac{F \cdot L}{A \cdot E}

From the above equation, we have that the elongation is inversely

proportional to the cross sectional area, such that the extension of a rod by

a given force reduces as the cross sectional area of the rod increases.

Therefore, the force required to extend the length of a rod by a specific

amount increases as the cross sectional area of the rod increases,

indicating that the rod with the largest cross sectional area require the

most force and therefore, experiences the largest force.

The rod that experiences the largest force is the rod with the largest cross

sectional area, which is <u>rod B</u>

seraphim [82]

Answer:

Explanation:

There is no set way to do this. All you have to do is define left and right. Left will be minus and right will be the opposite --- plus.

That is completely arbitrary. It could be the other way around. It does not matter.

Left is minus so: - 600 N   is the force going left.

Right plus so: + 500 N

Now just add.

Net Force = +500 - 600

Net Force = - 100 N

So the Net Force is - 100 N going to the left.
