To look firm and mature, fruits are artificially ripened. A chemical compound placed in the fruit crates produces acetylene gas with the help of the fruits moisture, which in turn speeds up the ripening process. This gas may affect our neurological system, can cause headache, dizziness, mood disturbances, sleepiness, mental confusion, memory loss, cerebral oedema and seizures. The chemical compound is 

In olden days, to calculate the distance of a particular star from Earth, the first measurement was taken from the Earth on one side of the sun, and the second was taken half a year later from the Earth when it was on the other side of the sun. This method helps in calibrating distance using calculations of trigonometric parallax. The unit for such measurements, the parsec (parallax of one arc second), is commonly used unit of distance in astronomical publications. 1 parsec is about

The energy required to overcome air resistance goes up at the cube of speed. It takes about 10% more fuel to cover a given distance at 110 kmph than at 100 kmph. Driving at 90 kmph reduces fuel consumption by around 20% relative to driving at 110 kmph. To conserve energy U.S. introduced the national speed limit during the OPEC petroleum pinch in the 1970s which is

Unit of electricity is kilowatt-hour (kWh). A 1000-watt bulb burning continuously for 1 hour consumes 1 kilowatt-hour of current. Bulbs have a very low efficiency as only 5% of electricity used is converted to useful light and the majority to heat. A Compact Fluorescent Lamp (CFL) gives 50 times more light, and consumes only 15% energy, in comparison to an ordinary bulb of same wattage.  If 1kWh is consumed by ordinary 1000-watt bulb in one hour and the cost of 1kWh consumed is 10 cents, how much can 12 CFLs of same wattage save over 12 ordinary bulbs burning 12 hours everyday for 30 days?
