A pitcher releases a fastball that moves toward home plate.

Vsevolod [243]

The two additional forces that act on the ball as it travels between the pitcher and the home plate are air resistance and gravity.

<h3>What are the forces that affect object in motion;</h3>

Air resistance: this is the force that oppose the motion of an object in air due to frictional force
Gravity: this is the force due to weight of the object and acts downwards.

The two additional forces that act on the ball as it travels between the pitcher and the home plate include:

Air resistance and
Gravitational force

<h3>How the forces affect the motion of the ball</h3>

Air resistance oppose the motion of the ball as it travels in air.
Gravity is the force due to weight of the ball and acts downwards.

A parallel plate capacitor is made of two large plates ofarea

Murrr4er [49]

Answer:

$C = \frac{\epsilon_0 \epsilon_1 A}{\epsilon_0 t + \epsilon_1(a-t)}\\$

Explanation:

If there is a dielectric slab with thickness less than the distance between the plates is inserted inside a capacitor, then that capacitor can be regarded as two capacitors connected in series.

Let's assume that the slab is placed onto the lower side. So, the capacitance of that part of the capacitor, C1 is

$C_1 = \epsilon_1\frac{A}{t}$

where $\epsilon_1$ is the permittivity of the slab.

The other part of the capacitor is

$C_2 = \epsilon_0 \frac{A}{a-t}$

Two capacitors are connected in series:

$\frac{1}{C} = \frac{1}{C_1} + \frac{1}{C_2} = \frac{1}{\epsilon_1 \frac{A}{t}} + \frac{1}{\epsilon_0 \frac{A}{a-t}} = \frac{t}{\epsilon_1 A} + \frac{a-t}{\epsilon_0 A} = \frac{\epsilon_0 t + \epsilon_1 (a-t)}{\epsilon_0 \epsilon_1 A}\\C = \frac{\epsilon_0 \epsilon_1 A}{\epsilon_0 t + \epsilon_1(a-t)}$
