The acceleration of the electron is larger than the acceleration of the proton.
The reason for this is that the mass of the electron is smaller (about 1000 times smaller) than the mass of the proton. The two particles have same charge (e), so they experience the same force under the same electric field E:
However, according to Newton's second law, the force is the product between the mass particle, m, and its acceleration, a:
which can be rewritten as
we said that the force exerted on the two particles, F, is the same, while the mass of the electron is smaller: therefore, from the last formula we see that the acceleration of the electron will be larger than that of the proton.
Answer:
The amount of mass that needs to be converted to release that amount of energy is
Explanation:
From Albert Einstein's Energy equation, we can understand that mass can get converted to energy, using the formula
where = change in mass
c = speed of light =
Making m the subject of the formula, we can find the change in mass to be
There fore, the amount of mass that needs to be converted to release that amount of energy is 1.122 X 10 ^-7 kg
Answer:
a blaring trumpet is sound energy
Explanation:
Answer: Air
Explanation: Of the three mediums (gas, liquid, and solid) sound waves travel the slowest through gases, faster through liquids, and fastest through solids. Air and hydrogen have nearly the same elastic properties, but the density of hydrogen is less than that of air. Sound thus travels faster (about 4 times as fast) in hydrogen than in air.
Answer:
Their densities are different as well
Explanation:
Density is worked out by dividing mass by volume. If the mass was the same then the densities would be as well. But it's not.
