Answer:
Inertia
Explanation:
The term for the tendency is inertia.
<em>The inertia of a body is the tendency of the body to remain unmoved when at rest and the tendency to keep moving when in motion. In other words, it is the tendency of a body to remain in a state of rest or motion. </em>
A static body will remain in a state of perpetual rest if no force acts on it and a moving body will keep moving in the same direction if no force acts on it. The force that needs to be overcome in order to change the state of the object is otherwise known as inertia force.
Answer:
im pretty sure its 10 m/s but its kinda hard sorry
Explanation:
Answer:
The absorption line spectrum shows what we see when we look at a hot light source (such as a star or light bulb) directly behind a cooler cloud of gas. Suppose instead that we are looking at the gas cloud but the light source is off to the side instead of directly behind it. In that case, the spectrum would be an emission spectrum.
Explanation:
Kirchhoff’s laws establish that:
- A solid, liquid or dense incandescent gas emits a continuous spectrum.
- A hot and diffuse gas produces bright spectral lines (emission lines).
- A gas of lower temperature against a source of continuum spectrum, produces dark spectral lines (absorption lines) superposed in the continuum spectrum.
According with Kirchhoff's laws it is get an emission line spectrum¹ in the scenario at which the observer is looking directly at a gas cloud with the light source off to the side from the line of sight.
In this case the atoms, molecules or ions in the medium are excited by the radiation that comes from the light source. That is known as an electronic transition², an electron in the atom or ion will absorb the photon coming from the light source and pass to a higher energy level, the electron, upon returning to its base state will emit a photon or a series of photons.
Keys terms:
¹Spectrum: Decomposition of light in its characteristic colors (wavelengths).
²Electronic transition: When an electron passes from one energy level to another, either for the emission or absorption of a photon.
Answer:
The question is incomplete as some details are missing, here is the details ;
In this final state
a) spheres #1 and #2 both carry negative charge.
b) sphere #1 carries negative charge and #2 carries positive charge.
c) spheres #1 and #2 are still uncharged.
d) sphere #1 carries positive charge and #2 carries negative charge.
e) spheres #1 and #2 both carry positive charge.
Explanation:
From the concept of electrostatics, if a positively charged sphere is brought close to #2, there will be attraction of the opposite charges(-ve) towards it.
Now connecting a copper wire between #1 and #2, opposite charges will flow from #1 towards #2. disconnecting the copper wire makes #1 to be positively charged and #2 to be negatively charge and from the laws of attraction ; Like charges repel and unlike charges attract. the correct option is d.
The work done by a system kept at constant pressure is given by:
where
p is the pressure
is the final volume
is the initial volume
If we plug the numbers given by the problem into this equation, we find
And since
, we have that the work done is
