An artificial leaf could replicate photosynthesis but instead it would also be artificial which then produces hydrogen fuel that will be energy efficient and carbon neutral. hope this helps.
Jet streams are fast moving air currents much like how a river is a fast moving water current so the answer is jet streams.
Hi there!
There is a way that the human body cools itself, but it sounds so weird!
Did you know that when you sweat after doing something constantly, the sweat tries to cool the body down? It's true!
I learned this is physical science class, and we tested it for ourselves. We ran around a bunch of times around my old school and then we started sweating. Not too long afterwards, we started cooling down because of the sweat.
Weird, right?
Hope this helps!
Message me if you need anything else! :D
Did you ever figure out the answer?
Answer:
Object C
Explanation:
Object A has two arrows, one pointing up and one pointing down. Since both arrows are the same length, the forces cancel, and Object A will not move.
Object B also has two arrows, one pointing up and one pointing down. However, the downwards pointing arrow is much longer than the other. This means it has more force and the object will move down.
Object C has two arrows, one pointing up and the other down. However, the upwards pointing arrow is longer than the other, meaning it has more force and the object will move upward.
Object D has two arrows, but both are pointing downwards, meaning the object will move down.
