Answer:

A rock sitting on the edge of a cliff. If the rock falls, the potential energy will be converted to kinetic energy, as the rock will be moving. The potential energy decreases as the kinetic energy increases. The potential energy decreases as the kinetic energy decreases.

To solve this problem it is necessary to apply the concepts related to the Period of a body and the relationship between angular velocity and linear velocity.

The angular velocity as a function of the period is described as

$\omega = \frac{2\pi}{T}$

Where,

$\omega =$ Angular velocity

T = Period

At the same time the relationship between Angular velocity and linear velocity is described by the equation.

$v = \omega r$

Where,

r = Radius

Our values are given as,

$T = 24 hours$

$T = 24hours (\frac{3600s}{1 hour})$

$T = 86400s$

We also know that the radius of the earth (r) is approximately

$6.38*10^6m$

Usando la ecuación de la velocidad angular entonces tenemos que

$\omega = \frac{2\pi}{T}$

$\omega = \frac{2\pi}{86400}$

$\omega = 7.272*10^{-5}rad/s$

Then the linear velocity would be,

$v = \omega *r$

x $v = \omega *r$

$v= 463.96m/s$

The speed would Earth's inhabitants who live at the equator go flying off Earth's surface is 463.96

From the formula for Electric Power, P = IV, P = V²/R

So the 100W compared to the 50W.

From P = IV. From the equation there is a direct relationship between P and I. More Power P means more Current, I.

From P = V²/R. From the equation, there is an inverse relationship
between P and R. Therefore more P means less R.

So from these assertions, the answer is:

(1) less resistance and draws more current
