After the following code is executed what will be displayed on the screen? bool correntEmployee = true; double empSalary = 45000

; if (correntEmployee) { if (empSalary < 45000) cout << "The employee needs a pay raise.\n"; else cout << "The employee pay rate is normal.\n"; } else cout << "This person is not an employee.\n";

Answer:

"The employee pay rate is normal" is the correct answer for the above question.

Explanation:

  • The above question code is written in the c++ language, in which there is one variable of bool type whose value is true.
  • And this variable is also tested in the if-condition which gives the true and the if-body will be executed.
  • Then the internal if-condition will give the false result because the value of the empsalary is not less than 45000. It is because the above statement "empsalary=45000" will assign the value 45000 on the empsalary variable.
  • Then the else block will be executed which prints "the employee pay rate is normal".

2. Consider a 2 GHz processor where two important programs, A and B, take one second each to execute. Each program has a CPI of
allsm [11]

Answer:

program A runs in 1 sec in the original processor and 0.88 sec in the new processor.

So, the new processor out-perform the original processor on program A.

Program B runs in 1 sec in the original processor and 1.12 sec in the new processor.

So, the original processor is better then the new processor for program B.

Explanation:

Finding number of instructions in A and B using time taken by the original processor :

The clock speed of the original processor is 2 GHz.

which means each clock takes, 1/clockspeed

= 1 / 2GH = 0.5ns

Now, the CPI for this processor is 1.5 for both programs A and B. therefore each instruction takes 1.5 clock cycles.

Let's say there are n instructions in each program.

therefore time taken to execute n instructions

= n * CPI * cycletime = n * 1.5 * 0.5ns

from the question, each program takes 1 sec to execute in the original processor.

therefore

n * 1.5 * 0.5ns = 1sec

n = 1.3333 * 10^9

So, number of instructions in each program is 1.3333 * 10^9

the new processor :

The cycle time for the new processor is 0.6 ns.

Time taken by program A = time taken to execute n instructions

=  n * CPI * cycletime

= 1.3333 * 10^9 * 1.1 * 0.6ns

= 0.88 sec

Time taken by program B = time taken to execute n instructions

= n * CPI * cycletime

= 1.3333 * 10^9 * 1.4 * 0.6

= 1.12 sec

Now, program A runs in 1 sec in the original processor and 0.88 sec in the new processor.

So, the new processor out-perform the original processor on program A.

Program B runs in 1 sec in the original processor and 1.12 sec in the new processor.

So, the original processor is better then the new processor for program B.

Your foot brake must be able to stop your car within __________ when it is travelling at 20 mph.
ohaa [14]

Answer:

Your foot brake must be able to stop car within 5.18 m

Explanation:

d = s^{2}  / (250 * c_{f} )

d is breaking distance.

s is speed in km/h

c_{f} is coefficient of friction normally 0.8

250 is  constant.

Give the speed in mile first convert it to km/h

1 km = 1.60934 mile

speed in km= 20 * 1.60934

s =32.186 km/h

d=32.186^{2}  / (250 * 0.8)

d= 5.18m
