What is the angular velocity of the minute hand on a clock? 1 Expert Answer There are 2*pi radians in a complete circle, so imagine the minute hand moving around a circular clock. It completes a full rotation around that circular clock in 60 minutes. So the angular speed of the minute hand is 2 […]

Does chromatic aberration make games look better? It is an effect that looks better in motion and not in screenshots. It gives the edges in the game a slightly feathered look to get rid of that CG Sharpness. In screenshots it just looks blurry and bad, so it is not really a good way to […]

What is a good sample size? A good maximum sample size is usually 10% as long as it does not exceed 1000. A good maximum sample size is usually around 10% of the population, as long as this does not exceed 1000. For example, in a population of 5000, 10% would be 500. In a […]

What is the equivalent of 10 mg? Convert 10 Milligram to Milliliters 10 Milligram (mg) 0.010000 Milliliters (ml) 1 mg = 0.001000 ml 1 ml = 1,000 mg How much energy is released when 1 g of mass is entirely converted into energy? Answer. So, using this formulae, Energy released= [{1*10^(-3)} * (3* 10^8)^2] joules […]

Are grandfather clocks worth anything? Longcase clocks, even the battered, dusty and stored-in-the-garage-because-it-doesn’t-work variety, can be worth from hundreds to tens of thousands of pounds, according to a specialist. Do grandfather clocks increase in value? Grandfather clocks can have a high investment value as long as they are maintained and restored carefully. A high quality, […]

How do you find the maximum acceptance angle? Acceptance Angle in Optical Fibre Calculation The acceptance angle is the maximum angle at which light-ray enters or hits the fiber core and getting propagate though it in zig-zag path. What is the maximum acceptance angle? The maximum angle of incidence (i) in air for which all […]

What is the most common first symptom of gonorrhea? Symptoms include: discharge from the vagina (watery, creamy, or slightly green) pain or burning sensation while urinating. urge to urinate more frequently. heavier periods or spotting. sore throat. pain during sexual intercourse. sharp pain in the lower abdomen. fever. Who has the highest rate of STDs? […]

Do resistors have a positive and negative side? Resistors don’t care which leg is connected to positive or negative. The + means where the positive or red probe of the volt meter is to be placed in order to get a positive reading. This is called the “positive charge” flow sign convention. Does it matter […]

Does ReadWorks cost money? As always, as part of our nonprofit mission, ReadWorks is completely free. How do you read a passage? How to Read the Passages A good standard approach is to glance over the corresponding questions before you begin to read the first passage. Quickly read the information blurb that comes at the […]

How is electrical energy formed? Electrical energy is caused by moving electric charges called electrons. In power stations, turbines are turned using energy from sources such as heat, wind and moving water. Generators are machines for converting motion energy into electricity. What holds the most energy? Sorbothane® has been recognized as the highest performance, energy-absorbing […]
