Is oil a good energy source? Oil is particularly useful as a fuel because of its high energy density. As previously mentioned, the original energy source of oil is the Sun, as the energy stored within dead organic matter is what creates crude oil over time. Why is oil a bad energy source? Burning Fossil […]

Can binaural beats make you hallucinate?
Can binaural beats make you hallucinate? Some people may hallucinate, in their own experience. Binaural beats are very subjective, some many people can listen to the exact same beat and have a different experience. They all have a particular frequency which helps to alter your brainwave pattern. This induces a state of mind depending on […]
What are the disadvantages of resistance training?
What are the disadvantages of resistance training? ISOMETRIC ISOTONIC Disadvantages: angle specific limited use in sports limited strength and endurance gains cannot monitor intensity large increases in blood pressure higher injury risk (free weights, uncontrolled movement) expensive weight lifted is limited by the ‘sticking point’ more muscle soreness Should I do resistance training everyday? One […]
What keeps the moon moving in a circular motion?
What keeps the moon moving in a circular motion? Gravitational attraction provides the centripetal force needed to keep planets in orbit around the Sun and all types of satellite in orbit around the Earth. The Earth’s gravity keeps the Moon orbiting us. It keeps changing the direction of the Moon’s velocity. What changes continuously in […]
What is light quality?
What is light quality? Light quality is the wavelength (in nanometers, nm) within the electromagnetic spectrum; i.e. blue light is 450 nm and red light is 650 nm. Each wavelength has a different packet of radiation or energy (in J mol-1) called photons. What type of light causes damage to plants? UV-B radiation has been […]

What are the 8 lab safety rules?
What are the 8 lab safety rules? General Laboratory Safety Rules Know locations of laboratory safety showers, eyewashstations, and fire extinguishers. Know emergency exit routes. Avoid skin and eye contact with all chemicals. Minimize all chemical exposures. No horseplay will be tolerated. Assume that all chemicals of unknown toxicity are highly toxic. What are the […]
How does the angle of deviation depends on the refracting angle of the prism?
How does the angle of deviation depends on the refracting angle of the prism? The angle of deviation (δ) increases with the increase in the angle of prism (A). What is the angle of deviation when angle of incidence is 60? Answer. The angle of deviation will be 60° only. As refracted ray goes strainght […]
