Answer:
No, the net force on the skydiver is zero
Explanation:
According to Newton's Second Law, the net force on an object is equal to the product between the mass of the object and its acceleration:
where
F is the net force
m is the mass of the object
a is the acceleration
In this problem, the acceleration of the skydiver is zero:
a = 0
This implies that also the net force on the skydiver is zero, according to the previous equation:
F = 0
So, the net force on the skydiver is zero. This occurs because the air resistance, which points upward, exactly balances the force of gravity on the skydiver, acting downwards.
Answer:
The interference pattern from a diffraction grating will have a wide, central bright band with alternate dark and bright bands on both sides, and the interference pattern will have an equally spaced dark and bright band.
Explanation:
In diffraction pattern we know that the distance between two consecutive minimum position is maximum
So here position of minimum is given as
now we have central maximum is of maximum width while all other have width of decreasing order.
While when we use Young's double slit pattern then we can say that position of all maximum and minimum intensity on the screen will be at same distance.
so here we have
so all the maximum and minimum intensity will have equal width.
