What is responsible for creating distinct weather patterns?

Two electrodes, separated by a distance d, in a vacuum are maintained at a constant potential difference. An electron, accelerat

Alja [10]

Answer:

Explanation:

Given that, the distance between the electrode is d.

The electron kinetic energy is Ek when the electrode are at distance "d" apart.

So, we want to find the K.E when that are at d/3 distance apart.

K.E = ½mv²

Note: the mass doesn't change, it is only the velocity that change.

Also,

K.E = Work done by the electron

K.E = F × d

K.E = W = ma × d

Let assume that if is constant acceleration

Then, m and a is constant,

Then,

K.E is directly proportional to d

So, as d increase K.E increase and as d decreases K.E decreases.

So,

K.E_1 / d_1 = K.E_2 / d_2

K.E_1 = E_k

d_1 = d

d_2 = d/3

K.E_2 = K.E_1 / d_1 × d_2

K.E_2 = E_k × ⅓d / d

Then,

K.E_2 = ⅓E_k

So, the new kinetic energy is one third of the E_k

What causes earthquakes,tsunami, and volcanic eruptions to happen certain places and not others

Dafna11 [192]

These are all caused by tectonic plate movements. Some areas of the globe are more susceptible to these disasters because they are on or near a fault line where the Earth’s tectonic plates rub against one another, slip beside and under each other, or collide. The places near fault lines are more likely to see earthquakes, tsunamis, and volcanic activity.

"A circuit consists of a battery and two resistors connected in parallel. If the resistance in both resistors is doubled, and th

sveticcg [70]

Let's call R the value of the resistance of the two resistors. In the first situation, the resistors are connected in parallel, so their equivalent resistance is given by:
$\frac{1}{R_{eq}}=\frac{1}{R}+\frac{1}{R}=\frac{2}{R}$
which means:
$R_{eq}=\frac{R}{2}$
And calling I the current in the circuit, the voltage is given by Ohm's law:
$V=IR_{eq}=\frac{IR}{2}$

In the second situation, the resistance of each resistor is doubled: R'=2R. So, the equivalent resistance in this case is given by
$\frac{1}{R_{eq}}=\frac{1}{2R}+\frac{1}{2R}=\frac{2}{2R}=\frac{1}{R}$
which means
$R_{eq}=R$
And the new voltage is given by:
$V'=IR_{eq}=IR=2V$
which is twice the original voltage, so the voltage has doubled.
