Hydrostatic pressure is independent of directions.
Answer:
The Ferris wheel's tangential (linear) velocity if the net centripetal force on the woman is 115 N is <u>3.92 m/s</u>.
Explanation:
Let's use <u>Newton's 2nd Law</u> to help solve this problem.
The force acting on the Ferris wheel is the centripetal force, given in the problem:
.
The mass "m" is the <u>sum</u> of the man and woman's masses:
.
The acceleration is the centripetal acceleration of the Ferris wheel:
.
Let's write an equation and solve for "v", the tangential (linear) acceleration.
The Ferris wheel's tangential velocity is 3.92 m/s.
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:
An object gets charged when it's atoms lose or gain an electron to become an ion. For example: ... This means that the fur loses it's electrons to the plastic rod and both objects are now charged. The fur is positively charged because it lost electrons and the rod is negatively charged because it gained electrons
