Answer:
n = 3
Explanation:
We know that the nth-order maximum for the Young's two-slit experiment is given by the following expression:
dsin(θ) = nλ
If two maxima concides we must have the relation:
nλ1 = mλ2 --- eq1
In this particular experiment
m = n+1
λ1 = 680 nm
λ2 = 510 nm
Replacing m in eq1 we have
nλ1 = (n+1)λ2
Solving for n we have:
n = λ2/(λ1-λ2)
Therefore:
n = 510/(680-510)=3
The correct option is (b) 5n
A result, the object is being acted upon by a net downward force of 5N.
The force that is produced by summing the vector sums of all the forces acting on an object is known as the resultant force. The effect of the resulting force is the same as the sum of all the acting forces operating on the object. The direction of the forces must be considered when calculating the resulting force.
The northward force is Fn = 10N, given.
Fs=15N is the southern force.
The net force on the phone is Fnet =?N, which is necessary.
Downward pressure is applied by the object's weight, and upward pressure is applied by upward resistance. The vector sum of these two forces will represent the net force.
Fnet = Fs - Fn (Considering the direction downward as positive)
Fnet = 15N - 10N
Fnet = 5N
There is a net downward force of 5 N acting on the object as a result.

Answer: The energy required to change water from a liquid to a solid is 333.7 kJ/kg while the energy required to boil water is 2257 kJ/kg. The amount of energy needed to change the phase of water to a gas from a liquid is 540 times the amount of energy needed to raise the same amount of water 1° C
Explanation:
Knowing that the momentum(p) of an object is directly (when one number goes up the other will too) related to both the mass and velocity of an object or p=mv, two rolling bowling balls of different masses can have the same momentum because the one with the lower mass, has a higher velocity. The higher velocity of an object would make up for the lower mass and vice versa.
