What is the difference between non science and pseudoscience? In short, while not all non-science is pseudoscience, all pseudoscience is definitely non-science. While pseudoscience is the most dangerous subspecies of non-science, philosophical discussions of the problem of demarcation aim to extract those features that make science what it is. Does science have to be falsifiable? […]

Can a peregrine falcon kill a human? A peregrine has between 4 to 8 times as much mass as a baseball, and can move at twice the speed of a fastball. That’s between 16 and 32 times the kinetic energy of a baseball. It is difficult to estimate the time of the collision accurately, but […]

What will be the resistance of 100w 210v lump? Resistance of the bulb: 625 Ω is the resistance of a bulb rated 100w ,250v. What is the resistance of the bulb marked as 20w 220v? Answer. putting values we get R= 242 ohm. What is the resistance of a bulb at 500w 220V? R=(220V)2100W=484Ω. What […]

At what temperature does fusion welding takes place? 900°C Is welding permanent or temporary? Welding is a permanent joint and therefore it is not possible to dismantle the welded parts without partially destroying them. Riveting joint is another permanent joint; while fasteners, cotter joint, knuckle joint, etc. are temporary joints. What are permanent and temporary […]

How fast is 7 horsepower? How much is 212cc in mph? This engine is a performer right out of the box, and should get your go kart running anywhere from 20 mph all the way up to 35mph in its stock form. How fast can a 1 hp engine go? A 1-horsepower engine couldn’t maintain […]

What is tolerance in a resistor? The tolerance of a resistor is the maximum difference between its actual value and the required value and is generally expressed as a plus or minus percentage value. For example, a 1kΩ ±20% tolerance resistor may have a maximum and minimum resistive value of: Maximum Resistance Value. What are […]

Why is a propane torch lit inside a hot air balloon? Propane torch is lit inside a hot air balloon during pre-flight preparation because the heat from the touch is needed to heat the cold air inside the balloon, so that the air will expand and become less dense and rise, thus providing a lift […]

What is meant by 1 molar solution? A 1 molar (M) solution will contain 1.0 GMW of a substance dissolved in water to make 1 liter of final solution. Hence, a 1M solution of NaCl contains 58.44 g. How do you make 200ml of a 0.1 M solution? How do we make the 0.1 M […]

What is always true when there is sea breeze? Sea breezes occur during hot, summer days because of the unequal heating rates of land and water. During the day, the land surface heats up faster than the water surface. Therefore, the air above the land is warmer than the air above the ocean. Recall that […]
