Questions

Temperate Cyclones are cyclones of mid-latitudes and hence are primarily under influence of permanent winds of mid-latitudes i.e. westerlies. Their movement is therefore eastwards of their origin with average velocity of 32km per hour in summers and 48km per hour in winters.

Movement of Tropical CyclonesNormally, they move from east to west under the influence of trade winds because trade winds are permanent winds of tropical latitudes. The general direction is therefore westwards from their origin. They advance with varying velocities. Weak cyclones move at the speed of about 32km per hour while hurricanes attain the velocity of 180km per hour or more.

Ionisation energy is the energy required to remove one mole of electrons from one mole of gaseous atoms. Atoms are more stable when they have full valence shells.

The ionization energy decreases from top to bottom in groups, and increases from left to right across a period.

HGence, in this trend Francium (Fr) has the lowest ionization energy.

The average Life span of RBC is 120 days.

Software testing is verifying if a software meets the customer's requirements; if it has high quality; if it is bug free and if it is fit for use. Testing is important because it ensures that the product delivered is defect free which in turn emphasizes higher quality and proves to be cost effective.
