1) Feather is Slow in Falling Down Because of Air-Resistance. (Extra: A Few Years Ago, this Experiment was done. After Removing Air, Feather and a Ball touched the Ground at Same time. You can Find it on YouTube)
3) (iii) the action or fact of making something smaller or less in amount, degree, or size.
(iv) the heaviness of a person or thing. Formula = mass * Pull of Gravity
4) Direct current (DC) is the flow of electric charge in only one direction. It is the steady state of a constant-voltage circuit. Most well-known applications, however, use a time-varying voltage source. Alternating current (AC) is the flow of electric charge that periodically reverses direction.
2) Similarities: -Both of Equations are Exothermic.
-Both Reactions from Strong Basic Solutions.
Differences: -NaOH is a Strong Base which Dissociates to From Na+ and OH- ion. While CaO added to Water froms CaOH which Further Dissociates.
-NaOH and CaOH should be added to Water Gradually with Constant Stirring. CaO on Reacting with Water Produces a Basic Solution called CaOH which is used from Whitewashing and this Reaction is More Dangerous when compared to NaOH.
7) Specific heat capacity is defined as the amount of heat required to raise the temperature of 1 kilogram of a substance by 1 kelvin
SI unit of specific heat capacity J kg−1 K−1
