Answer 2

1. The spark ignites the flammable gas causing a flame to come out of the lighter which continues until either the top is closed or the valve is released (butane type). An electric spark starts the initial flame, and soon the coil is hot enough to cause the fuel–air mixture to burn on contact.
2. Cell phones use radio waves to communicate. Radio waves transport digitized voice or data in the form of oscillating electric and magnetic fields, called the electromagnetic field (EMF). The rate of oscillation is called frequency. Radio waves carry the information and travel in air at the speed of light.
3. There are 8 planets in the universe
