Answer:
More energy
Explanation:
The amount of energy carried by a wave is related to the amplitude of the wave itself. In particular, the amount of energy carried by the wave is proportional to the square of the amplitude of the wave:
where
E is the energy
A is the amplitude
This means, for instance, that if the amplitude of a wave is doubled, the energy it carries increases by a factor 4.
Answer:
Explanation:
By conservation of energy, the sum of the kinetic and gravitational potential energies at the surface of the Earth must be equal than their sum at infinity, so we have:
Where is the gravitational constant,
and
are the mass and radius of the Earth, <em>m </em>is the mass of the particle,
its velocity at the surface of the Earth (which would be its escape velocity) and
and
are the velocities and distance at infinity, which would be null and infinity respectively, so the right hand side of our equation is 0J, which leaves us with:
Also, since the force the molecule experiments is the force of gravity (disregarding drag), we can write its weight in terms of Newton's Law of Gravitation:
Which means that:
So finally putting all together we can write:
Answer:
KE = 54450 J
Explanation:
Data:
Use the formula:
Replace and solve:
A kinetic energy of <u>54450 Newtons</u> is imparted to it.
