Answer:
The distance between interference fringes increases.
Explanation:
In a double-slit diffraction pattern, the distance of the n-order fringe from the centre of the pattern is
where 
is the wavelength of the light, D the distance of the screen, and d the separation between the slits.
If we take two adjacent fringes, n and (n+1), their distance is
so, we see that it is inversely proportional to the slit separation, d.
Therefore, if the separation between the slits decreases, the distance between the interference fringes increases.
Answer:
0.06 Nm
Explanation:
mass of object, m = 3 kg
radius of gyration, k = 0.2 m
angular acceleration, α = 0.5 rad/s^2
Moment of inertia of the object
I = 3 x 0.2 x 0.2 = 0.12 kg m^2
The relaton between the torque and teh moment off inertia is
τ = I α
Wheree, τ is torque and α be the angular acceleration and I be the moemnt of inertia
τ = 0.12 x 0.5 = 0.06 Nm
Answer:
It gives you the symbol, mass, and the number of protons, neutrons, and electrons of elements.
Answer: b. Salt lakes are formed when river bends are cut off.
Salt lakes are formed when water from water sourced gets accumulated in a shallow region and the supply of water is cut. These salt lakes are terminal which means water does not flow to other locations. Therefore, salt lakes are formed when river bends are cut off.
<h2>
Option A is the correct answer.</h2>
Explanation:
For a simple pendulum we have at any position
Total energy = Constant
Kinetic energy + Potential energy = Constant
At maximum displacement of pendulum, velocity is zero, hence kinetic energy is zero.
At maximum displacement the pendulum only have potential energy.
Given that maximum potential energy is 10 J.
That is at any position
Kinetic energy + Potential energy = 10 J
Now we need to find kinetic energy when potential energy is 5 J.
Kinetic energy + 5 J = 10 J
Kinetic energy = 5 J
Option A is the correct answer.
