scientific theory is the answer
Looking at the image attached, When the distance from a to b was increased, the pitch of the sound would be lower.
<h3>What is the pitch of a sound?</h3>
The pitch of a sound is known to be how high or low the sound that is played is.
A high sound is known as a sound that has a high pitch and a low sound is known to be the one that has a low pitch. In the above picture, the pitch will be lowered when the distance is increased.

Below is the proof that the sum of two odd numbers is always even.
<h3>
How to prove that the sum of two odd numbers is even?</h3>
First, remember that an even number is written as:
x = 2*n
Where n is an integer number.
While an odd number will be written as:
y = 2*n + 1
Now, let's say that we have two odd numbers:
A = 2k + 1
B = 2n + 1
If we add these we get:
A + B = (2k + 1) + (2n + 1) = 2k + 2n + 2 = 2*(k + n + 1)
And k + n + 1 is an integer number, then we can write:
k + n + 1 = N
So we get:
A + B = 2N
Then the sum of A and B is an even number.
Thus, we proved that for the sum of any two odd numbers, the outcome will always be even.

The number of total bytes in memory is 32,000 bytes.
<h3>
How many total bytes in memory?</h3>
We know that the memory is composed of 8k (or 8,000) words of 32 bits each.
To get the total memory, we just need to take the product between the number of words and the memory that each has.
This will give:
8,000*(32 bits) = 256,000 bits.
But we want this in bytes so we need to change the units, remember that:
1 bit = 0.125 byte.
Then we have:
256,000 bits = 256,000*( 0.125 byte) = 32,000 bytes.
The memory has 32,000 bytes in total.

The speed of block B in terms of the distance (d) it has descended is
<h3>How to determine the speed.</h3>
In order to determine the speed of block B in terms of the distance (d) it has descended, we would apply the work-energy theorem as follows:
The work done due to gravity is given by:
The work done due to friction is given by:
The angular velocity of pulley is given by:
Applying the work-energy theorem, we have:
