The net force with be 10 N east. As both boys are pushing a wagon to the same direction, you just add the numbers together. If the directions were opposite like if it was the boy pushing 6 N east and the other boy pushing 4 N west...then it would come out as 2 N east (you subtract and go to the direction with the biggest number) if you have any confusions, feel free to ask
The light reactions could be viewed as analogous to a hydroelectric dam. In that case, the wall of the dam that holds back the water would be analogous to the thylakoid membrane.
Thylakoid membrane is present in cyanobacteria and chloroplasts of plants. It plays a crucial role in photosynthesis and photosystem II reactions.
In general, these are the regions where light-dependent reactions take place. The thylakoid membrane is a lipid-bound membrane that maintains potential difference and also controls the flow of liquids across the membrane during light reactions.
In the provided case, we can see that the wall of the dam holds back the water, similarly, in light-dependent reactions, thylakoid membranes control the liquid flow and also regulate the potential gradient across the membrane and also allow the selective proteins to pass through.

One should never anchor in a narrow channel, until unless required very importantly. One should stay to the starboard side, and use a prolonged blast. The announcement must be done to alarm the nearby vessels, about your approach. The vessel should be kept at the outer limit of the starboard side.
The
speed of sound depends on any form of matter or medium in which sound travels
through it and depends on the amount of molecular collisions. Sound travels slowest in gas in the form of steam
because the sound has to move around the gas molecules that are far apart making
it harder for the
energy of vibrations hit the particles and make sound.
Moreover,
sound travelling through solids like ice is much faster because the particles
are closer together so the sound waves do not have to travel that far making the
number of collisions greater and sound spread more easily.
Power is energy per unit time. If he is powerful, it means he can spend more energy in short span of time, so option C ( i.e. <span>do more work in less time) is correct.</span>
