Earth turns on its axis about once every 24 hours. The Earth's equatorial radius is 6.38 x 106 m. If some catastrophe caused Ear
san4es73 [151]

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

xv = \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

Alecsey [184]

Answer: The correct answer is- Field.

Explanation -

The modified space around a charged particle is known as electric field.

The strength of electric field at a point is calculated as the force experienced by a unit test charge present at that point.


Thus, a region of space in which a test charge experiences a force is referred to as Field.
