Answer:
Part a)
Width of the slit is
Part b)
Ratio of intensity is given as
Explanation:
Part a)
As we know by the formula of diffraction we will have
so we have
so we will have
Part b)
As we know that the intensity in diffraction pattern is given as
so for angle 45 degree
It's not in motion when the line straight and flat . there's #9
The law of reflection states that the angle of incidence and the angle of reflection will always be equal.
When a ray of light reflects off a surface, the angle of reflection is equal to the angle of incidence.
Explanation:
Given that,
Mass of the block, m = 300 g = 0.3 kg
Linear spring constant, k = 6.5 N/m
(a) Let T is the period of the block's motion. It is given by :
where
= angular frequency
Also,
T = 1.34 seconds
(b) The maximum acceleration of the block is, 
The maximum acceleration is given by :
A is the amplitude of the motion,
A = 0.09 meters
Hence, this is the required solution.
Gravitational force is given by the following formula:
F = GMm/r^2
Where;
F = Gravitational force, G = Gravitational constant, M & m = masses of two bodies which are constant in this case, and r = distance between the masses.
It can be seen that F α 1/r^2.
Therefore, the far the two masses are from each other, the smaller the gravitational force and vice versa.
It is indicated that:
AB = 300 km
BC = 400 km
CA = 100 km
Therefore,
gravitational force will largest between C and A due to smaller distance between them.<span />
