How many forces are required for an interaction? Two forces Is it worth restringing a tennis racquet? As we mentioned earlier, the general rule of thumb for restringing a tennis racket depends on how much you play per week. If you play 3 or 4 times a week, then you should consider replacing its strings […]

What is the coefficient of friction of steel? The coefficient of static friction for steel is around 0.6–0.15 and the coefficient of kinetic friction is around 0.09–0.6. The making of steel involves many processes and stages. What is the coefficient of friction between plastic and steel? Coefficient of Friction Materials Static Sliding Dry Greasy Leather […]
Did Einstein know about Michelson-Morley experiment?
Did Einstein know about Michelson-Morley experiment? Yes, Einstein was aware of the Michelson-Morley experiment. The Michelson-Morley experiment looked for an absolutely stationary space the Earth moves through. The near-null result is evidence the aether is not an absolutely stationary space. What was the purpose and conclusion of Michelson-Morley experiment? The purpose of the Morley-Michelson experiment […]
How do you find the range of an individual series?
How do you find the range of an individual series? Range Individual Series: Subtract the lowest from the highest observation. Discrete Series: Same as Individual Series. Continuous Series: Range is calculated by taking the difference between the upper limit of the highest class interval and the lower limit of the lowest class interval. Does ungrouped […]
Does electricity emit CO2?
Does electricity emit CO2? Approximately 40% of global CO2 emissions are emitted from electricity generation through the combustion of fossil fuels to generate heat needed to power steam turbines. Burning these fuels results in the production of carbon dioxide (CO2)—the primary heat-trapping, “greenhouse gas” responsible for global warming. Did dinosaurs become oil? The notion that […]

Is oil used to reduce friction?
Is oil used to reduce friction? Motor oil is used for lubrication of internal combustion engines. The main function of motor oil is to reduce friction and wear on moving parts and to clean the engine from sludge (one of the functions of dispersants) and varnish (detergents). Why do bearings reduce friction? Bearings reduce the […]
What happens if you drink saltwater?
What happens if you drink saltwater? Seawater is toxic to humans because your body is unable to get rid of the salt that comes from seawater. Your body normally gets rid of excess salt by having the kidneys produce urine, but it needs freshwater to dilute the salt in your body for the kidneys to […]

Anabolic steroids. Steroid precursors. Amphetamines and other stimulants. Caffeine. Do drugs make you run faster? Using drugs to boost performance isn’t a new development. Steroids can help body-builders to […]
How are goods allocated if Qd Qs?
How are goods allocated if Qd Qs? When the supply and demand curves intersect, the market is in equilibrium. This is where the quantity demanded and quantity supplied are equal. The corresponding price is the equilibrium price or market-clearing price, the quantity is the equilibrium quantity. Quantity supplied is equal to quantity demanded ( Qs […]
