Answer: Nicotinamide adenine dinucleotide phosphate (NADP)

Explanation:

<u>Photosynthesis</u> is a metabolic process in which light is transformed into stable chemical energy, converting inorganic matter into organic matter.

This process is mainly divided in two parts:

-Light-dependent reactions (also called light reactions)

-Light-independent reactions (also called dark reactions).

In the case of light reactions, the light is used by the plant to produce organic energy molecules, being the coenzyme Nicotinamide adenine dinucleotide phosphate (NADP) the final electron acceptor.

It should be noted, this coenzyme is also involved in the dark phase of photosynthesis, in which carbon dioxide ( $CO_{2}$ ) is fixed into carbohydrates.

Two forces act at a point in the plane. The angle between the two forces is given. Find the magnitude of the resultant force. fo

Zielflug [23.3K]

Answer:

408N at 89.89°

Explanation:

This problem requires that we resolve the force vectors into

x- and y

-componentsOnce this is done, we can add the components easily, as the one 2-dimensional problem will be two 1-dimensional problems.

Finally, we will convert the resultant force into standard form and find the equilibrant.

Resolve into components:

F1x =F1cos 180°= 232(−1)=−232N

F1y=F1sin180°=0N

F2x=F2cos(−140°)=194(−0.766)=−148.6N

F1y=F1sin(−140°)=232(−0.643)=−149.17N

Note the change of the angle used to give the direction of

F2. Standard angles (rotation from thex

-axis; counterclockwise is +) should be used to avoid sign errors in the results.

Now, we add the components:

Fx=F1x+F2x=−380.6N

Fy=F1y+F1y=−148.17N

Technically, this is the resultant force. However, it should be changed back into standard form. Here's how:

F=√(Fx)2(Fy)2=√(−380.6)^2(−148.17)^2=408N

θ=tan−1(−148.17−380.6)

=89.89°

You have two identical beakers A and B. Each beaker is filled with water to the same height. Beaker B has a rock floating at the

gregori [183]

Answer:

a) if we assume that the water does not spill, Beaker B weighs more than beaker S, or which in this case Beaker A weighs more

b) If it is spilled in water the weight of the two beakers is the same

Explanation:

The beaker weight is

beaker A

W_total = W_ empty + W_water

Beaker B

W_total = W_ empty + W_water + W_roca

a) if we assume that the water does not spill, Beaker B weighs more than beaker S, or which in this case Beaker A weighs more

b) If it is spilled in water, the weight of the two beakers is the same because the amount of liquid spilled and equal to the weight of the stone, therefore the two beakers weigh the same

Compression and rarefaction are two phenomenon occurs in longitudunal wave!

when there is denser particle gathering in that wave , there we called it compression and the rarer part of particles is rarefaction !
