The circumference of the earth is 40,000 km. The distance from the

Finger [1]

Answer:

The distance from the North Pole to the equator is $1*10^{7}$ m.

Explanation:

Circumference of Earth = 40,000 km ......................(1)

Distance from the North Pole to the Equator is = 1/4th of the Circumference of Earth ...................... (2)

Let Distance from the North Pole to the Equator be d ,

the equation formed will be ,

d = 1/4 * Circumference of Earth ........(3)......... ( from equation 1 )

put the value of Circumference of Earth in equation (3),

d = 1/4 * 40,000 km

d = 10,000 km

converting km to m ,

d = 10,000 * $10^{3}$ m

d = 1 * $10^{7}$ m

The distance from the North Pole to the equator is $1*10^{7}$ m.

An object at rest starts accelerating.

Shalnov [3]

Answer:

<u>We are given: </u>

initial velocity (u) = 0 m/s

final velocity (v) = 10 m/s

displacement (s) = 20 m

acceleration (a) = a m/s/s

<u>Solving for 'a'</u>

From the third equation of motion:

v² - u² = 2as

replacing the variables

(10)² - (0)² = 2(a)(20)

100 = 40a

a = 100 / 40

a = 2.5 m/s²
