I dint think energy can be used up because energy cant be created nor destroyed
Answer:
Explanation:
When a lightning bolt travels from the cloud to the ground it actually opens up a little hole in the air, called a channel. Once then light is gone the air collapses back in and creates a sound wave that we hear as thunder. The reason we see lightning before we hear thunder is because light travels faster than sound!
Answer:
The capacitance of a capacitor depends on the charge and voltage of a system. It is also dependent, if present, on the dielectric as well.
General Formulas and Concepts:
<u>Gauss's Law</u>
Capacitance Formula: 
- <em>Q</em> denotes charge
- <em>V</em> denotes voltage
Dielectric Capacitance Formula: 
- <em>C₀</em> denotes original capacitance
- <em>κ</em> denotes the dialectic constant
Explanation:
A <u>capacitor</u> <em>stores</em> charge when run through an electrical current. The <u>capacitance</u> is <em>how much </em>charge a capacitor can hold.
We can define the relationship of capacitance by using the formula. Capacitance is <em>inversely proportional</em> to the potential energy, or <u>voltage</u>, of the system. Therefore, you will need to know what the <u>charge</u> Q of the system as well has voltage V in order to find the capacitance.
If there is a dielectric involved inside the capacitance, you also must incorporate the value of the <u>dielectric constant </u>into your capacitance. A dielectric is <em>directly proportional </em>to the capacitance; the bigger the dielectric constant, the bigger capacitance, as denoted in our equation.

Answer:
C. the time interval for stopping is greater.
Explanation:
As the egg falls onto the grass, it takes a a greater amount of time for it to stop, and thus the force that is being applied to it is in increments; there is never enough force applied on the egg for it to break. That's why the egg doesn't break when it lands on the grass.
In contrast, when the egg is dropped on the road, <em>all of the force that is being applied by the road on the egg is in the tiny interval when the egg touches the road</em>, That force is large enough to break the egg because it is being applied in a tiny amount of time. That's why the egg dropped on the road breaks.
<em>So here is the rule of thumb: if you don't want to break your things but still want to drop them, drop them such that it takes some for them to stop—because force will applied to them gradually. </em>
