Why do we have two tides a day? This occurs because the moon revolves around the Earth in the same direction that the Earth is rotating on its axis. Since the Earth rotates through two tidal “bulges” every lunar day, we experience two high and two low tides every 24 hours and 50 minutes. What […]
What is the stimulus for hearing?
What is the stimulus for hearing? Sound. Sound, the stimulus for hearing, is made up of a series of pressures, usually of air, that can be represented as waves.

When the magnet is kept stationary in the coil?
When the magnet is kept stationary in the coil? (iii) When the magnet is held stationary in the coil, there will be a magnetic flux in the coil but it will remain constant. Since the magnetic flux does not change, there is no induced current in the coil and the galvanometer shows no deflection. When […]
What causes fluorinated gas?
What causes fluorinated gas? Fluorinated gases are used inside of products like refrigerators, air-conditioners, foams and aerosol cans. Emissions from these products are caused by gas leakage during the manufacturing process as well as throughout the product’s life. Fluorinated gases are also used for the production of metals and semiconductors. What are some examples of […]

How do you convert frequency to wavelength?
How do you convert frequency to wavelength? Frequency (f) and wavelength (λ) are joined by the equation fλ = c, where c is the speed of light. As the speed of light is constant, if you increase the frequency, the wavelength must decrease to maintain this equation and vice versa. Are frequency and wavenumber the […]
What happens if a balloon is heated?
What happens if a balloon is heated? If a balloon is heated up, the gas inside will expand, causing the circumference of the balloon to increase. Similarly, if the balloon is cooled down, the gas inside contracts, and causes the balloon to shrink. Answer 4: This contraction of the students takes up less room, just […]
