Which component of the electric field is always continuous at the boundary? Which component of the electric field intensity is always continuous at the boundary? Explanation: At the boundary of the dielectric-dielectric, the tangential component of the electric field intensity is always continuous. How do you find initial boundary conditions? In most physical problems these […]

What are characteristics of a high pressure system?
What are characteristics of a high pressure system? A high pressure system has higher pressure at its center than the areas around it. Winds blow away from high pressure. Swirling in the opposite direction from a low pressure system, the winds of a high pressure system rotate clockwise north of the equator and counterclockwise south […]
What is the device that converts electrical energy to heat energy?
What is the device that converts electrical energy to heat energy? Generator What are the three devices that change electricity to heat energy? (1) Heater and home appliances like press iron, geyser etc, converts electrical energy into heat energy. (2) Electric bulb and rods converts heat energy to light energy. (3) A motor and robot […]
Can science explain bicycles?
Can science explain bicycles? Engineer Jim Papadopoulos, the subject of Scientific American’s feature, demonstrated that a bike with significant negative trail can be ridden, as long as it has a weight jutting out front. That weight could, in theory, come from cargo on a front rack. How do I make my bike pedal easier? Eight […]

Can binaural beats release dopamine?
Can binaural beats release dopamine? For instance, it might be that binaural beats induce, or increase the size of phasic dopamine bursts, which might have a stronger impact in individuals with a relatively low tonic dopamine level. What is the science behind binaural beats? Binaural beats are an auditory illusion caused by listening to two […]
Which of the following is the example of free convection?
Which of the following is the example of free convection? A microwave oven cooking a meal. Can heat be transferred by convection? When a fluid, such as air or a liquid, is heated and then travels away from the source, it carries the thermal energy along. This type of heat transfer is called convection. The […]

What happens if these colors passes through another prism?
What happens if these colors passes through another prism? When light passes through a prism the light bends. As a result, the different colors that make up white light become separated. This happens because each color has a particular wavelength and each wavelength bends at a different angle. What happens if light passes through 2 […]
