C) it decreased
because atmospheric pressure decreases as we move up.
Line c is at rest . line a is going in a positive direction . line b is going in a negative direction . line d is negative too
Energy is conserved when driving a car when the car is not using gas it is not using energy therefor conserving energy
I know something that a lot of people know but they get in trouble when they try to use it. I got it a long time ago from my old school buddy Ike Newton. I'll tell it to you, but you have to keep it to yourself, don't spread it around, and don't tell a lot of people where you got it.
Here it is:
<em>For every action, there is a reaction that is EQUAL and opposite. </em>
That means that if Jane pushes on the rock with 100 Newtons of force,
then <u><em>The rock pushes on Jane with 100 Newtons of force.</em></u>
It doesn't matter how much Jane's mass is, it doesn't matter what the mass of the rock is, and it doesn't even matter whether Jane is moving, or the rock is moving, or both of them are moving. If there's an action, then you can bet yer britches that there's a RE-action, and the RE-action is EQUAL and OPPOSITE to the action.
Why is this so hard ?
Ions conduct electricity in an electrolyte as ions are positively or negatively charged atoms. i.e. they are either cations (+vely charged) or anions (-vely charged)
