Is high salinity bad? If the level of salts in the soil water is too high, water may flow from the plant roots back into the soil. This results in dehydration of the plant, causing yield decline or even death of the plant. Crop yield losses may occur even though the effects of salinity may […]

Does speed increase as pressure increases? Bernoulli’s Principle states that as the speed of a moving fluid increases, the pressure within the fluid decreases. Does increasing pressure increase speed? In this case when the gas is compressed to half the volume, the pressure is doubled. Therefore for such case, speed of the gas particles remains […]

Can you fall off the moon? Although you can jump very high on the moon, you’ll be happy to know that there’s no need to worry about jumping all the way off into space. In fact, you’d need to be going very fast – more than 2 kilometres per second – to escape from the […]

Why is the current atomic model called the electron cloud? The modern model is also commonly called the electron cloud model. That’s because each orbital around the nucleus of the atom resembles a fuzzy cloud around the nucleus, like the ones shown in the Figure below for a helium atom. The densest area of the […]

What are the similarities and differences between cellular respiration and fermentation? Describe the similarities and differences between cellular respiration and fermentation. Both produce ATP through the breakdown of carbon based molecules, and both allow glycolysis to continue by recycling electron acceptors. Cellular Respiration requires oxygen and produces much more ATP than fermentation. What are 3 […]

How much does a Newton of force feel like? “A Newton is about ¼ pound, the weight of a stick of margarine.” Weight is the downward force of gravity exerted on an object by the planet it is located on. What is a pound of thrust? Thrust is a force or a push. Thrust is […]

What happens when the frequency of a sound wave decreases? If frequency decreases, pitch decreases and produces a lower sound. Frequency and wavelength are inversely related, meaning that if frequency increases, wavelength becomes shorter and vice versa. Therefore, if frequency increases, pitch increases and creates a higher sound and wavelengths become shorter. Why is sound […]
