Answer:
914m
Explanation:
We must divide the parachutist motion into three parts:
First we have free fall motion:
Then, we have a uniformly accelerated motion. The initial speed is this part will be the same final speed as the previous part.
Finally, we have a uniform linear motion:
The total heigh will be the sum of all heights:
Answer: The Normal Force
Explanation:
According to Third Newton's Law, also konwn as The principle of action and reaction :
<em>"If a body A exerts an action on another body B, it performs on A another action that is the same and in the opposite direction."</em>
In this case this is what happens with the book on a table, gravity force pulls it downward, but the Normal Force (perpendicular to the surface of the table) acts in the opposite direction with the same magnitude, preventing the book from accelerating downward.
I believe the answer is A. hope this helps :)
Answer:
c
Explanation:
the charge wants to ultimately balance out so either you or the slide gave the other electrons to balance the charges
A or B... I mean when lava is poured out to the surface, heat and soilica content may play a role... That's what I think sorry :(
