What is difference between space and orbit? What’s the difference between ‘outer space’ and ‘orbit’? Answer: Outer space begins somewhere around 1,200 miles above the Earth. Orbit occurs when an object’s momentum perpendicular to the Earth’s surface creates sufficient centrifugal force to counteract Earth’s gravity. Is rocket science actually hard? Rocket science is hard Getting […]
Who is the father of classical physics?
Who is the father of classical physics? Galileo Galilei Why did Einstein oppose quantum mechanics? Einstein always believed that everything is certain, and we can calculate everything. That’s why he rejected quantum mechanics, due to its factor of uncertainty. Who can file a suit upon quantum meruit? A claim of quantum meruit hence is a […]

What is Catenation explain with reference to group 14?
What is Catenation explain with reference to group 14? The property of self-linking of atoms of an element through covalent bonds to form straight or branched chains and rings of different sizes is called catenation. Amongst the group 14 elements, C-C bond strength (355 kJ mol1) is maximum, therefore, carbon shows maximum tendency for catenation. […]
Why are CO2 levels increasing?
Why are CO2 levels increasing? Carbon dioxide concentrations are rising mostly because of the fossil fuels that people are burning for energy. For 2018 alone, global fossil fuel emissions reached 10 ± 0.5 Pg C yr−1 for the first time in history (Friedlingstein et al. 2019). About half of the CO₂ emitted since 1850 remains […]
Why is the waste from nuclear power dangerous?
Why is the waste from nuclear power dangerous? Dangers of Radioactive Waste [1] High-level waste is produced as part of the nuclear fuel process and needs to be considered in order to avoid permanent damage to living organisms and the environment. [2] These dangerous byproducts remain intensely radioactive for a long time. Can nuclear waste […]
Can a Boeing 747 break the sound barrier?
Can a Boeing 747 break the sound barrier? As it shot across the Atlantic, the Boeing 747-400 jet reached a top ground speed of 825 mph. However, the jet did not actually break the sound barrier, because that is measured by its airspeed, or the speed of the plane relative to the air through which […]
What is the minimum separation of the plates?
What is the minimum separation of the plates? Return the moveable plate to the minimum 0.15 separation; the voltage should return to 5 volts. Since Q = CV and the charge remains constant during the plate separation changes, if the capacitance C decreases as 1/d, then the voltage V across the plates must increase as […]

What are the 3 ways humans work to reduce flooding?
What are the 3 ways humans work to reduce flooding? Some methods of flood control have been practiced since ancient times. These methods include planting vegetation to retain extra water, terracing hillsides to slow flow downhill, and the construction of floodways (man-made channels to divert floodwater). What is the problem with levees? In addition, by […]
