A hard drive with a spin speed of 7200 RPM, commences spinning at time = 0, at time = 1.326 ms what is the angle that the disk h

Flura [38]

Answer: I. 57º 17' II. 1 rad.

Explanation:

A spin speed, implies the relationship between the angle rotated and the time that has been spinning, which is equal, by definition, to the angular velocity.

ω = Δ∅ / Δt

In order to get the angle rotated in degrees, we need to convert first from RPM (revolutions per minute) to º/sec, as follows:

7200 rev/min *( 1 min/60 sec)* (360º/ 1 rev) = 7200* 6= 43200 º/s

Now, we know that the time passed since it started to spin, was 1.326 msec, i.e., 0.001326 sec.

Remembering that ω = Δ∅ / Δt, solving for Δ∅, we get:

Δ∅ = 43200 º /s * 0.001326 sec = 57º 17'

II. In order to get the answer in rads, we can convert the rpm to rads/sec, as follows:

7200 rev/min *( 1 min/60 sec)* (2 π/ 1 rev) = 240 π rad/sec.

Applying the same equation as above, we get:

Δ∅ = 240 π rad/s * 0.001326 sec = 1 rad.

Consider the following relation: CAR_SALE (Car#, Date_sold, Salesman#, Commision%, Discount_amt Assume that a car may be sold by

Nady [450]

Answer:

See explaination

Explanation:

The given relation is:

CAR_SALE(Car#, Date_sold, Salesperson#, Commission%, Discount_amt)

Primary key: {Car#,Salesperson#}

We will first check whether the relation is in 1NF.

A relation is said to be in the 1st Normal form(1NF) if all the columns in the relation have atomic values. In this case, the relation is in 1NF.

A relation is said to be in the second normal form(2NF) if it satisfies the condition that all non keys are completely dependent on the primary key and just a part of the primary key.

In the case of the CAR_SALE relation, the Commission% depends only on the Salesperson# and not on the combination of Car# and Salesperson#. This means that the given relation is not in 2NF. To satisfy 2NF, we make two relationships as given below:

SALE_DETAIL(Salesperson#, Commission%)

and CAR_SALE(Car#, Date_sold, Salesperson#, Discount_amt)

Now both the relations are in 2NF.

For a relation to be in 3NF, no non-key should be functionally dependent on another non key.

In the case of the CAR_SALE relation, it is specified that the Date_sold field determines the Discount_amt. Therefore the modified CAR_SALE is not in 3NF.

To satisfy 3NF, we seperate the non key and the dependent non key and create a different table.

Final Relations:

SALE_DETAIL(Salesperson#, Commission%)

Discount_Detail(Date_Sold, Discount_Amt)

CAR_SALE(Car#, Date_sold, Salesperson#)

(Java) Write a program that accepts a number of minutes and converts it both to hours and days. For example, 6000 minutes is 100

iogann1982 [59]

Import java.util.Scanner;
public class MinutesConversion {
private static Scanner inputDevice;
public static void main(String[] args) {
int minutes, hours;
float days; // float for decimal point

inputDevice = new Scanner(System.in);
System.out.println("Please enter minutes for conversion >> ");
minutes = inputDevice.nextInt();
hours = minutes / 60;
days = hours / 24.0f;

System.out.println(+ minutes + " minutes is " + hours + " hour(s) or" + days " days");
}

Suppose we have a 4096 byte byte-addressable memory that is 32-way high-order interleaved, what is the size of the memory addres

iogann1982 [59]

Answer:

Explanation:

Given that :

Byte-addressable memory = 4096

Order = 32

Rwqritying such that they have the same base ;

4096 = 2^12

32 = 2^5

2^12 - 2^5

12 - 5 = 7
