Since you solved a and b I will start with part c.
Part C
To answer this question we need to find zeros of a velocity function:
We can factor this polynomial:
Now it's pretty easy to find zeros. This function will be equal to zero when any of the factors are equal zero.
We solve these two equations and we get our zeros:
The particle is at rest at t=0 and t=3/2.
Part D
To solve this we need to determine when our velocity function is greater than zero. We will use factored form.
We determine when each factor is greater than zero and with that information, we build the following table:
We can see, from the table, that our function is positive when
and t>3/2.
That is the range in which particle is moving in positive direction.
Part E
We know that distance traveled is given with:
We simply plug in t=12 to find total distance traveled:
Part F
We know that acceleration is defined as a rate of change of velocity.
We find acceleration by taking the first derivative of velocity with respect to time.
To find acceleration after 1 second we simply plug in t=1s in above equation:

Answer:
The value is
Explanation:
From the question we are told that
The wavelength of each source is
The distance from the pinhole
The diameter is
Generally from Rayleigh's criterion we have that the distance between the sources of light for their diffraction patterns is mathematically represented as '
