Question

2. Distances travelled by Hamid and Akhtar in an hour are 9 km and 12 km .Find the ratio of speed of Hamid to the speed of Akhtar.

Answer 1

Answer:

An electric generator is a device that converts mechanical energy obtained from an external source into electrical energy as the output. ... Instead, it uses the mechanical energy supplied to it to force the movement of electric charges present in the wire of its windings through an external electric circuit.

Answer 2

Step-by-step explanation:

The distance travelled in an hour by a certain object is called the speed of the object.

Distance travelled by Hamid in one hour=9km

Distance travelled by Akhtar in one hour=12km

Hamid's speed=9km/hr

Akhtar's speed=12km/hr

Ratio of speed of Hamid to the speed of Akhtar=9/12

=3/4.
