Question

It takes 6 minutes for the signal sent by an artificial
satellite orbiting around the earth to reach the ground
station. Calculate the distance of the artificial satellite
from the ground station. The signal travels with the
speed of light, i.e. 3 x 108 m/s. [Ans. 1.08 x 108 km]

Answer 1

Hello friend!!!

Your question is to find the distance of this distance of spaceship from the ground when the signal travelling at the speed 3 into 10 to the power 8 reach the ground after 5 minutes.

♦1 minute is equal to 60 seconds

♦5 minutes is equal to 60×5 seconds = 300 seconds

★So the distance = speed × time

= 300 × 3 ×10 to the power 8

=9 × 10 to the power 10 meters

★So the distance of the spaceship from the ground is 9 × 10 to the power 10 meters

HOPE THAT HELPS.... ☺️

Answer 2

Concept:

A scalar quantity, speed is defined as the size of the change in an object's location over time or the size of the change in an object's position per unit of time.

Given:

The time taken to send the signal by an artificial satellite orbiting around the earth to reach the ground station is 6 minutes.

The speed of sound is $3\times 10^8 m/s$.

Find:

The distance between the artificial satellite and the ground station.

Solution:

The time taken to receive the signal is 6 minutes.

$6min=6\times 60=360 sec$.

Now,

Speed= Distance/ time

The speed of sound is $3\times 10^8 m/s$.

Therefore,

The distance of the artificial satellite from the ground station is

$d=3\times 10^8 \times 360\\d=1080\times 10^8m\\d=1.08\times 10^8km$

The distance of the artificial satellite from the ground station is $1.08\times 10^8 km$.
