Why Galilean transformation is failed? Maxwell’s equations, which summarise electricity and magnetism, cause the Galilean Transformation to fail on two counts …. They predict the speed of light is independent of the inertial reference frames instead of ($c’=c+v$) as required by Galilean Relativity. They are not invariant under the Galilean Transformation. Who gave Galilean transformation? […]
Which is the best example of heat being transferred mainly by radiation?
Which is the best example of heat being transferred mainly by radiation? Heat transfer by radiation occurs when microwaves, infrared radiation, visible light, or another form of electromagnetic radiation is emitted or absorbed. An obvious example is the warming of the Earth by the Sun. A less obvious example is thermal radiation from the human […]
Why does a spoon look bigger in a glass of water?
Why did the number of dark peppered moths increase after the 1850s?
Why did the number of dark peppered moths increase after the 1850s? The evolution of the peppered moth is an evolutionary instance of directional colour change in the moth population as a consequence of air pollution during the Industrial Revolution. Later, when pollution was reduced, the light-coloured form again predominated. Did moths used to be […]
How many plates are on Mars?
How many plates are on Mars? two plates Is Olympus Mons still growing? Scientists posit that Olympus Mons is still a fairly young volcano from a geologic standpoint, estimating it to be only a few million years old. That being said, there’s a good chance that it’s still active and could erupt at some point […]
Is there anything that takes space?
Is there anything that takes space? Matter is anything that has mass and takes up space. Is water being traded? Water has joined gold, oil and other commodities that are traded on Wall Street, as worries about the uncertainty of its availability in the future rises. What is the best water stock to buy? The […]
What nerve makes the heart beat slower?
What nerve makes the heart beat slower? The word “vagal” refers to the vagus nerve. It’s a long nerve that runs from the brain down through the chest and into the abdomen. The vagus nerve has several functions, including slowing the heart rate. Can your heart continue to beat even if your cerebrum is not […]
When the switch is open the bulb is on when the switch is closed the bulb is off?
What is electrical energy Grade 4?
What is electrical energy Grade 4? Electrical energy is the energy derived from electric potential energy or kinetic energy of the charged particles. In general, it is referred to as the energy that has been converted from electric potential energy. How do cell phones use electrical energy? Electrical energy flows through the power cord into […]
Is heat directly proportional to resistance?
Is heat directly proportional to resistance? Temperature is directly proportional to Resistance . So that’s why Heat is directly proportional to Resistance . Does Resistance go up or down with heat? Electrons flowing through a conductor are impeded by atoms and molecules. The more these atoms and molecules bounce around, the harder it is for […]
