It has 9 zeroes. Similarly a trillion has 12 zeroes,a quadrillion 15 zeroes,a quintillion 18 zeroes and a decillion 33
zeroes. • One inch is equal to 2.5400 cms and one mile is equal to 1.6093 kms. • One micron is equal to One-thousandth of a millimeter. • 2.47105 acres is equal to what SI unit-Hectare • What word describes one tenth of a nautical mile-Cable • What is measured on the Torro scale -Tornados • unit of sound named after- Alexander Graham Bell – Decibel • The density Smoke is measured on the
Rngelmann scale- • Unit of electromotive force in Volt. • Power is measured in Watts (w). • Resistance was discovered by Girge Ohm in 1826, and is measured in ohms. • Electricity does not flow through a circuit by itself. It needs a ‘push’, or energy, to keep it moving. We call this energy the voltage of the circuit. Voltage is measured in volts (v).
