Answer:
the longest time needed to read an arbitrary sector located anywhere on the disk is 2971.24 ms
Explanation:
Given the data in the question;
first we determine the rotational latency
Rotational latency = 60/(3600×2) = 0.008333 s = 8.33 ms
To get the longest time, lets assume the sector will be found at the last track.
hence we will access all the track, meaning that 127 transitions will be done;
so the track changing time = 127 × 15 = 1905 ms
also, we will look for the sectors, for every track rotations that will be done;
128 × 8.33 = 1066.24 ms
∴The Total Time = 1066.24 ms + 1905 ms
Total Time = 2971.24 ms
Therefore, the longest time needed to read an arbitrary sector located anywhere on the disk is 2971.24 ms
According to Newton's first law of motion, the puck gradually slows down because friction would be acting on it.
<h3>What is Newton's first law?</h3>
Newton's first law of motion states that an object will remain at rest or move uniformly in a straight line unless acted upon by an external force.
According to this question, a hockey puck is hit with a large force. The puck moves at a high speed as it slides over the ice.
However, in accordance with the first law of motion proposed by Newton, the puck gradually slows down because friction would be acting on it.
