Answer:
The pressure increases by a factor 8
Explanation:
For a gas held at constant temperature, Boyle's law can be applied. It states that the product of the gas pressure and the gas volume is constant, so we can write:
where
is the initial pressure
is the final pressure
is the initial volume
is the final volume
For the gas in this problem, the volume is reduced from
to
so we can rewrite the equation as
this means that the pressure of the gas will increase by a factor 8.

Answer:
we will have induced magnetic field towards us
now in order to induce the magnetic field towards us we must have induced current in the loop and its direction is counterclockwise.
Explanation:
As per lenz law we know that the rate of change in magnetic flux linked with the closed loop will induced EMF in the loop and the direction of this induced current in the loop will always oppose the causes due to which it is induced
Here we know that magnetic field is straight towards us and it start decreasing with time
So we can say that flux linked with the coil will also decrease with time
Now as per lenz law the induced magnetic field of the loop is in such a direction that it will increase the magnetic flux in the coil.
So we will have induced magnetic field towards us
now in order to induce the magnetic field towards us we must have induced current in the loop and its direction is counterclockwise.
Width of the fringes gets decreased if the distance between the slits is increased and thus we get narrower fringes.
What is Young's double-slit experiment?
- In modern physics, the double-slit experiment is a demonstration that light and matter can display characteristics of both classically defined waves and particles; moreover, it displays the fundamentally probabilistic nature of quantum mechanical phenomena.
- This type of experiment was first performed, using light, by Thomas Young in 1802, as a demonstration of the wave behavior of light.
- A wave is split into two separate waves (the wave is typically made of many photons and better referred to as a wave front (not to be confused with the wave properties of the individual photon)) that later combine into a single wave.
- Changes in the path-lengths of both waves result in a phase shift, creating an interference pattern.
- A coherent light source, such as a laser beam, illuminates a plate pierced by two parallel slits, and the light passing through the slits is observed on a screen behind the plate.
- The wave nature of light causes the light waves passing through the two slits to interfere, producing bright and dark bands on the screen – a result that would not be expected if light consisted of classical particles. However, the light is always found to be absorbed at the screen at discrete points, as individual particles (not waves); the interference pattern appears via the varying density of these particle hits on the screen.
- Furthermore, versions of the experiment that include detectors at the slits find that each detected photon passes through one slit (as would a classical particle), and not through both slits (as would a wave).
- However, such experiments demonstrate that particles do not form the interference pattern if one detects which slit they pass through. These results demonstrate the principle of wave-particle duality.
