Answer:

Execution time is 13.65ms

CPI is 5.46

MIPS is 73.3\ MIPs

Explanation:

Given:

s = 40MHz --- processor speed [Missing from the question]

\begin{array}{ccc}{Instruction\ Type} & {Instruction\ Count} & {Cycles\ per\ Instruction} & {Integer\ Arithmetic} & {45000} & {4} \ \\ {Data\ Transfer} & {32000} & {6} & {Floating\ point\ arithmetic} & {15000} & {10} & {Control\ Transfer} &{8000} & {3} \ \end{array}

Solving (a): The program execution time

First, we solve for (b)

Solving (b): The effective CPI

This is calculated as:

CPI = \frac{\sum IC * CI}{\sum IC}

Where: <em>IC = Instruction Count and CI = Cycles per Instruction</em>

So, the equation becomes:

CPI = \frac{45000 *4 + 32000 * 6 + 15000 * 10 + 8000 * 3}{45000+32000+15000+8000}

CPI = \frac{546000}{100000}

CPI = 5.46

Solving (c): MIPS

This is calculated as:

MIPS = Speed * \frac{1}{CPI} * \frac{1}{\sum IC}

MIPS = 40 * \frac{1}{5.46} * \frac{1}{100000}

MIPS = \frac{40 * 1 * 1}{5.46*100000}

MIPS = \frac{40}{546000}

MIPS = 0.00007326007

Convert to MIPs

MIPS = 73.3\ MIPs

Solving (a): Execution Time

This is calculated as:

Time = Instructions * CPI * \frac{1}{Speed}

Time = 100000 * 5.46* \frac{1}{40M}

Time = \frac{546000}{40M}

Time = \frac{546000}{40*1000000}

Time = \frac{546000}{40000000}

Time = 0.01365s

Time = 13.65ms

Execution time is 13.65ms

A Carnot cycle is to be designed to attain
Anni [7]

Answer:

reservoir is 727°C, then low temperature

Explanation:

Efficiency for any Heat engine = Work done by engine / Heat provided to the engine

Also, for a carnot engine derived formula for Carnot Engine

= 1- T2/T1

Where, T2 = sink reservoir temperature

and T1 = source reservoir temperature

727° C = 1000 K

So, 0.75 = 1-T2 / 1000

So, T2 = 1000*0.25 = 250 K = -23 Kelvin

harkovskaia [24]

Answer:

c. can destablize the slopes by increasing pore fluid pressure.

Explanation: A reservoir is a term used in Agriculture or geography to describe a location where water is either collected artificially or naturally for later use in farming or to act as dam for the supply of water in large communities. Most countries of the world make use of reservoirs to store water for future use.

A square plate of titanium is 12cm along the top, 12cm on the right side, and 5mm thick. A normal tensile force of 15kN is appli
Scrat [10]

Answer:

X_t=2.17391304*10^{-4}

X_r=2.89855072*10^{-4}

e_t=0.0026

e_r=0.0035

Explanation:

From the question we are told that:

Dimension 12*12

Thickness l_t=5mm=5*10^-3

Normal tensile force on top side F_t= 15kN

Normal tensile force on right side  F_r= 20kN

Elastic modulus, E=115Gpap=>115*10^9

Generally the equation for Normal Strain X is mathematically given by

 X=\frac{Force}{Area*E}

Therefore

For Top

 X_t=\frac{Force_t}{Area*E}

Where

 Area=L*B*T

 Area=12*10^{-2}*5*10^{-3}

 Area=6*10^{-4}  

 X_t=\frac{15*10^3}{6*10^{-4}*115*10^9}

 X_t=2.17391304*10^{-4}

For Right sideX_r=\frac{Force_r}{Area*E}

Where

Area=L*B*T

 Area=12*10^{-2}*5*10^{-3}

 Area=6*10^{-4}  

 X_r=2.89855072*10^{-4}

 X_r=2.89855072*10^{-4}

Generally the equation for elongation is mathematically given by

 e=strain *12

For top

 e_t=2.17391304*10^{-4}*12

 e_t=0.0026

For Right

 e_r=2.89855072*10^{-4} *12

 e_r=0.0035
