The outer planets (Jupiter, Saturn, Uranus, Neptune) are called the "<u>GAS</u> giants".
The rocky planets are called "rocky" because they're made of <u>ROCK</u>.
Does this help guide you to the correct choice ?
Here's another hint: The MOST dense planet in our solar system, the one we call "Earth", is one of the 'rocky planets'.
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.
Topic: AP Physics C - EMAG
Unit: Gauss's Law
Speed of the arrow just before it will hit the ground can be calculated by energy conservation
by solving above equation
now this will lodge itself 15 cm into the ground
so after lodging itself to 15 cm the speed of arrow becomes zero
now we will have
Now by Newton's II law net force is given as
I haven't worked on Part-A, and I don't happen to know the magnitude of the gravitational force that the Sun exerts on the Earth.
But whatever it is, it's exactly, precisely, identical, the same, and equal to the magnitude of the gravitational force that the Earth exerts on the Sun.
I think that's the THIRD choice here, but I'm not sure of that either.
Let’s come back to the equation of SPEED OF AN ECHO
SPEED =2XDISTANCE/ TIME
So 337*7/2=1179.5 nearest meter =1800 m away
Hope you will get it right
