Answer:
Plan A
Explanation:
Acceleration in a circle is toward the center of the circle, while velocity is always a straight line that's tangent to the circle. When the boy let's go of the rope the Acceleration toward the center of the circle disappears. The v ball then follows the straight path, tangent to the circle.
A circuit is an unbroken loop of conductive material through which electrons flow hope this helps :)
Answer:
Ionic and covalent bonding produce compounds, while hydrogen bonding and Van der Waals forces join separate molecules together.
Ur welcome:)
D.) Asteroids
Asteroids are large rocks that orbit the sun. They aren't considered planets since they are smaller.
Answer:
a) In a parallel plate capacitor the capacitance is
So, in order to halve the capacitance the plate separation should be twice the original distance.
b) Same question as (a).
c) According to the above equations, the charge stored in a capacitor is directly proportional to the plate separation.
In order to halve the charge stored the plate separation should be half the original distance.
d) Same question as (c).
e) The energy stored in a capacitor is
In order to halve the energy stored in the capacitor, the plate separation should be twice the original distance.
f) Same question as (e).
g) The energy density is given by the following equation
As it turns out, the energy density is independent from the geometric factors. This makes sense, because the electric field in a parallel field capacitor is independent from the distance.
