Explanation:
The misunderstanding here is that the thing that turns on the light bulb is not the same electrons near the light switch. So, the electrons near the switch is not moving all the way across the circuit instantly. The electrons are distributed across the wire. When the light switch is turned on, the circuit is connected and there is a potential difference between the bulb and the source. This potential difference creates an electric field, and free electrons move under the influence of this electric field according to Coulomb's Law. When they start to move the electrons closest to the bulb causes the bulb to glow.
So, the important factor here is not the drift velocity of the electrons but the number of electrons and the strength of the electric field.
Answer:
<h2>False.</h2>
Explanation:
A fossil fuel is a fuel formed by natural processes. Fossil fuels typically have an age of millions of years, and sometimes more than 650 million years. It cannot process to create fossil fuel again.
<h3>Further Explanation:</h3><h3 />
A nonrenewable resource is a natural substance that is not replenished with the speed at which it is consumed. It is a finite resource.
Nonrenewable resources come from the Earth. Humans extract them in gas, liquid, or solid form and then convert them for their use, mainly related to energy. The reserves of these substances took billions of years to form, and it will take billions of years to replace the supplies used.
Answer:
false
Explanation:
galleleio da Vinci and Newton did that
The higher the pressure, the higher boiling point of water. At lower the pressure, the boiling point of water comes down. So, the lower pressure inreases the boiling resulting more evaporation. As we go higher in altitude, the atmospheric pressure decreases. This results in decreasing the boiling point at higher altitude and increase in boiling of water. In fact, at the sea level ,the the sea water boils at 100 degree C where atmospheric pressre is normal. However , the boiling takes place at a lower temperature at the top of a mountain due to low pressure. In other words the boling is faster at the top of a mountain than that at its foot.
