China because it is cheaper then getting it from Pittsburgh
Answer:
Explanation:
The distance travelled in the free fall is H - h
Since the apple originally started from rest we can use v^2 = u^2 + 2 x g x s where v is the final velocity, g the accln due to gravity and s the distance travelled and u is the initial velocity = 0
So the velocity just before it enters the grass is sq rt [2 x g x (H - h)]
Once in the grass, it slows down at a constant rate which means that the acceleration (a) during this period is constant.
So once again using the same formula we have v = O and u = sq rt[2 x g x (H-h)]
so since v^2 = u^2 + 2 x a x s then
O^2 = 2 x g x (H-h) + 2 x a x h
{O^2 - 2 x g x (H - h)}/(2 x h) = a
Answer:
Balanced forces do not cause a change in motion. When balanced forces act on an object at rest, the object will not move. If you push against a wall, the wall pushes back with an equal but opposite force. ... Forces that cause a change in the motion of an object are unbalanced forces.
The Earth orbits the sun constantly, continuously, and all the time. " 24/7/365 "
From the sun's point of view, it takes the Earth roughly 365 and 1/4 days
to make the complete trip, all the way around one time. That's the length
of time that we call "one year".
When you talk about orbiting in one month, you're thinking of the moon
orbiting the Earth. THAT length of time is about 27.32 days.
Explanation:
Q = CV
where C = capacitance
V = potential difference
Solving for C,
C = Q/V = (9.6×10^-9)(120 v)
= 1.15 microFarads
