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 […]

Does buoyancy affect weight? An object will float if the buoyancy force exerted on it by the fluid balances its weight, i.e. if FB=mg F B = mg . But the Archimedes principle states that the buoyant force is the weight of the fluid displaced. So, for a floating object on a liquid, the weight […]

What is a magnetic field how can the direction? the magnetic fields are the imaginary line which moves from south to north. this lines do not overlap each other. we can find the direction of the magnetic field lines by keeping a compass near to it. Why do 2 magnets repel or attract each other? […]

How accurate are dial calipers? Quality dial, Vernier or digital calipers can all return an accuracy of about 0.001 inch over 6 inches if correctly used, although the accuracy is likely to diminish over longer spans. What are the 3 ways a dial caliper can be used to measure? There are 4 measurements you can […]

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 […]

Why is the atmosphere essential for life? Atmosphere is very important for sustaining life: It contains various gases like O2, CO2, N2 which are required for various life processes by plants and animals.

What is the angle of incidence when the incident ray is normal to the interface? Complete step-by-step answer: If the incident ray is on the same path as the normal to the surface, the angle of incidence will be zero. Therefore, the angle of incidence when light incident ray is along the normal to interface […]

Which of the following is the weakest bond? (a) H-bond is only an interaction between electronegative element and hydrogen therefore, it is the weakest bond among all. Why is Bond making exothermic? Bond forming is an exothermic process, because it releases energy. In reaction profile diagram, the energy change in a reaction, is the difference […]
