What is the difference between a force multiplier and a distance multiplier? Levers can be force multipliers, when they increase the force that is put in (the effort). They can be distance multipliers if they make the load move further than the effort. The amount the force or distance is multiplied depends on the distances […]
What is P-type semiconductor with example?
What is P-type semiconductor with example? A p-type semiconductor is a type of semiconductor. When the trivalent impurity is added to an intrinsic or pure semiconductor (silicon or germanium), it is said to be a p-type semiconductor. Trivalent impurities such as boron (B), gallium (Ga), indium (In), aluminium (Al) etc. are called acceptor impurity. Is […]

What is temperature really a measure of?
What is temperature really a measure of? Temperature is a measure of the average kinetic energy of the particles in an object. When temperature increases, the motion of these particles also increases. It’s not a terrible definition, but it’s not the best either. What is the difference between temperature and energy? Thinking about the learning […]

Is Earth losing its magnetic field?
Is Earth losing its magnetic field? Reversals occur nearly randomly in time, with intervals between reversals ranging from less than 0.1 million years to as much as 50 million years. The most recent geomagnetic reversal, called the Brunhes–Matuyama reversal, occurred about 780,000 years ago. Where is Earth’s magnetic field strongest? magnetic north pole Can humans […]
