<span>A wave is an oscillation or a disturbance which travels through space. During this motion these waves transfer the energy. While the transfer of energy it is not necessary for the mass transport. All waves can be represented using wave equation. Which is a time dependent one. And the representation of waves varied with the different types of waves. There are two types of waves. One is transverse wave and other one is longitudinal waves.</span>
Here are the answers on the questions represented above. I thing you don't need detailed explanation because these are just general facts.
14. true
15. true
16.false
17. false, obviously there should be more for making a system
You betcha !
-- Work is done whenever a force acts through a distance.
-- The skydiver has weight. That's the force acting on him.
-- As time goes on, I'm assuming that he falls from one height
to a lower height. That's the distance the force acts through.
-- The work done on him is (force) times (distance)
(his weight) x (distance he falls).
So where is the machine that does all this work ?
-- It's GRAVITY that does the work on him as he falls.
So how did he get all this energy in the first place ?
Where did it come from ?
-- From the airplane that lifted him up to height from which he jumped !
Your answer is B, a long time ago the continents that we know today used to be all one continent and was separated years ago due to earthquakes long ago. I think that's how it happend, but I am 100% sure its B
Answer:
inhibitor
Explanation:
Inhibitors slow down chemical reactions. Inhibitors slow down or stop the activity of an enzyme.
