When two particles with like charges are close enough to interact is the potential energy positive or negative? The graphs of potential energy between two charges for like and unlike charges are shown below. For like charges, the potential energy is always positive, that is because we need to put energy in the system to […]
Which country is coal rich and oil poor?
Which country is coal rich and oil poor? India: Rich in coal but poor in energy. What is chemical formula of oil? The chemical formula for crude oil is CnH2n+2, where n is a positive integer. Crude oil is basically a combination of several hydrocarbon molecules, comprising hydrogen, H and carbon atoms, C. Among the […]

Do magnets get stronger if you stack them?
Do magnets get stronger if you stack them? Once a magnet is fully magnetised, it cannot be made any stronger as it is fully ‘saturated’. As more magnets are stacked together, the strength will increase until the length of the stack is equal to the diameter. After this point, any further magnets added will provide […]
What is the oldest ice core sample?
What is the oldest ice core sample? The deepest ice core records come from Antarctica and Greenland, where the very deepest ice cores extend to 3 kilometers (over two miles) in depth. The oldest continuous ice core records extend to 130,000 years in Greenland, and 800,000 years in Antarctica. What two events must occur for […]
What was the conclusion of the gold foil experiment?
What was the conclusion of the gold foil experiment? Rutherford’s gold foil experiment showed that the atom is mostly empty space with a tiny, dense, positively-charged nucleus. Based on these results, Rutherford proposed the nuclear model of the atom. Why was gold foil used in Rutherford’s experiment? Rutherford used gold for his scattering experiment because […]
Does without slipping mean no friction?
Does without slipping mean no friction? For many dynamics problems, rolling without slipping means there is a friction force acting on the wheel at the contact point P. This friction force prevents slipping. In this instance the friction is known as static friction since there is no relative sliding between the wheel and surface at […]
What is the relationship between resistance and current?
What is the relationship between resistance and current? The relationship between current, voltage and resistance is expressed by Ohm’s Law. This states that the current flowing in a circuit is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit, provided the temperature remains constant. What is the property of […]
