Two objects allowed to move freely will accelerate toward each other
in response to the gravitational forces between them.
It doesn't matter whether they have equal masses or vastly different
masses ... each object accelerates toward the other one.
The less-massive object has greater acceleration, and the more-massive
object has smaller acceleration.
Yes. When you fall to the Earth, the Earth falls to you, but with less
acceleration because it has less mass than you have.
it is generated by two objects pushing against each other with equal/almost equal force, therefore contracting against each other
Answer:
3.84 erg
Explanation:
According to Hooke's law, the energy required to stretch a spring by x length is
where k is the spring constant. We can plug in E = 4 and x = 10 to estimate k
To stretch 4cm further (at 14cm), the total work required is
The additional work needed is 7.84 - 4 = 3.84 erg
First and foremost, a photon is quantum of light. It is otherwise known as visible light and has a wavelength range of 400 to 700 nm. Moving waves are describable by their frequency (number of waves per second) and wavelengths.
A single photon can be considered unique from other photons only by its energy. In empty space (vacuum), all photons have the same speed or velocity.
The frequency of the electromagnetic vibration, we know as light, is given in units of Hertz. One hertz is equivalent to one vibration per second; it must be noted that the range of spectrum perceived by the eye extends from 4.3 x 10∧ 14 Hz in the red to about 7.5 x 10∧ 14 Hz in the violet.
