What is the melting point of water? 0 °C Why water has high boiling point and freezing point? So despite its small molecular weight, water has an incredibly big boiling point. This is because water requires more energy to break its hydrogen bonds before it can then begin to boil. The same concept is applied to […]
What would be the path of reflected light if an incident ray passes through focus?
What would be the path of reflected light if an incident ray passes through focus? An incident ray passing through the focus will be reflected parallel to the principal axis. Why the light ray retraces its path when it passes through Centre of curvature? Answer: The reason for light falling on the centre of curvature […]

Can any human see infrared?
Can any human see infrared? Infrared waves are a portion of the light spectrum that follows red. They have longer wavelengths than visible light, ranging from 700 nanometers to one millimeter. This renders them invisible to humans in almost all conditions. What does the red light on a security camera mean? If it’s an infrared […]
How long is a freight train allowed to be?
How long is a freight train allowed to be? According to data that two Class I railroads provided to us, their average train length increased over the 10-year period of 2008 through 2017 by about 1,500 feet for one railroad (from about 6,000 to 7,500 feet, or up to about 1.4 miles) and about 1,200 […]

How do you calculate the voltage after a resistor?
How do you calculate the voltage after a resistor? Ohm’s Law states that V=I*R, where V is voltage, I is current and R is resistance. In a series circuit, the voltage drop across each resistor will be directly proportional to the size of the resistor. In a parallel circuit, the voltage drop across each resistor […]
Will Pangea form again?
Will Pangea form again? The last supercontinent, Pangea, formed around 310 million years ago, and started breaking up around 180 million years ago. It has been suggested that the next supercontinent will form in 200-250 million years, so we are currently about halfway through the scattered phase of the current supercontinent cycle. What is the […]
Why is Common Core bad?
Why is Common Core bad? By focusing on grade-level skills that are highly academic in nature, the Common Core puts pressure on teachers at the early childhood and primary levels to teach using paper-and-pencil methods rather than using the rich exploratory experiential learning approaches that are developmentally appropriate for children from … What is the […]
