1. Why is it not possible to reuse a heat pack in term of the chemistry?

2. Compare the specific heat of water to the specific heat of metal (Copper). Which would heat up faster (with less energy required)?

3. Why would metal make a poor ingredient in a heat pack?

4. If there was a delay between measuring the initial temperature of a hot object and its transfer to the calorimeter, how would the heat capacity of the object be affected? How would the calculation of the heat capacity of the calorimeter be affected (too high, too low, or no affect)?

The magnetic field has been measured to be horizontal everywhere along a rectangular path x= 22 cm long and y= 4 cm high, shown in the figure. Along the bottom the average magnetic field B1= 1.3 × 10^-4 tesla, along the sides the average magnetic field B2= 1 × 10^-4 tesla, and along the top the average magnetic field B3= 0.4 ×10^-4 tesla. What can you conclude about the electric currents in the area that is surrounded by the rectangular path?

I chose utilitarianism.

Utilitarianism: the government should chose policies that maximize the total utility of everyone in society. For example, giving $100 to a homeless person would have a bigger impact on his total utility or 'happiness' than giving it to millionaire money who probably see it as are change and therefore has little impact on his well-being.

Navidale, a listed engineering company, manufactures large scale plant and machinery for industrial companies. Until ten years ago, Navidale Limited purshed a strategy of organic growth. Since then, it has followed an aggressive policy of acquiring smaller engineering companies, which it feels have developed new technologies and methods, which could be used in its manufacturing process. However, it is estimated that only between 30% and 40% of the acquisitions made in the last ten years have successfully increased the company's shareholder value. Navidale Limited is currently considering acquiring Lochinvar, an unlisted company, which has three departments. Department A manufactures machinery for industrial companies, Department B produces electrical goods for the retail market, and the smaller Department C operates in the construction industry. Upon acquisition, Department A will become part of Navidale, as it contains the new technololgies which Navidale is seeking, but Departments B and C will be unbundled, whith the assets attached to Department C sold and Department B being spun off into a new company called Ndege Co.

Given below extracts of financial information for the two companies for the year ended 30 April 2014.

Navidale Co   Lochinvar Co

R Million R Million

Sales revenue: R790-2 R124.6

Profit before depreciation, interest and tax (PBDIT) R244.4    R37.4 million;

Interest R 13.8 R 4.3

Depreciation R 72.4 R 10.1

Pre tax profit R 158.2 R23.0

Non-current assets R723.9 R98.2

Current assets R142.6 R46.5

7% unsecured bond - R40.0

Other non-current and current liabilities R212.4 R20.2

Share capital (50c/share) R190.0 R20.0

Reserves R464.1 R64.5

Share of current and non-current assets and profit for Navidale Co's three departments:

Department A Department B Department C

Share of current and non-current assets 40% 40% 20%

Share of PBDIT and pre-tax profit 50% 40% 10%

Other information

(i) It is estimated that for Department C, the realisable value of its non-current assets is 100% of their book value, but its current assets' realisable value is only 90% of their book value. The costs related to closing Department C are estimated to be R3 million.

(ii) The funds raised from the disposal of Department C will be used to pay off Lonchivar Co's other non-current and current liabilities.

(iii)The 7% unsecured bond will be taken over by Ndege Co. It can be assumed that the current market value of the bond is equal to its book value.

(iv) At present, around 10% of the Department B's PBDIT come from sales made to Department C.

(v) Ndege Co's cost of capital is estimated to be at 10%. It is estimated that in the first year of operation Ndege Co's free cash flows to firm will grow by 20% and then by 5-2% annually thereafter.

(vi) The tax rate applicable to all the companies is 20%, and Ndege Co can claim 10% tax allowable depreciation on its non-current assets. It can be assumed that the amount of tax allowable depreciation is the same as the investment needed to maintain Ndege Co's operations.

(vii) Navidale Co's current share price is R3 per share and it is estimated that Lochinvar Co's price-to-earnings (PE) ratio is 25% higher than Navidale Co's PE ratio. After the acquisition, when Department A becomes part of Navidale Co, it is estimated that Navidale Co's PE ratio will increase by 15%.

(viii) It is estimated that the combined company's annual after-tax earnings will increase by R7 million due to the synergy benefits resulting from combining Navidale Co and Department A.

Required:

4.1 Discuss the possible reasons why Navidale Co may have switched its strategy of organic growth to one of growing by acquiring companies.(4)

4.2 Discuss the possible actions Navidale Co could take to reduce the risk that the acquisition of Lochinvar Co fails to increase shareholder value (7)

4.3 Estimate, showing all relevant calculations, the maximum premium Navidale Co could pay to acquire Lonchivar Co, explaining the approach taken and any assumptions made. (14)

The following functions have zero or more security issues given the way they are called in the main() function. Identity these security issues and propose a compliant fix. You don’t need to consider the issues in the main() function.

1. setValue set the element at index in arr to value.

void setValue ( int * arr , int len , int value , int index ) {

                arr [ index ] = value ;

}

int main ( void ) {

                int arr [10];

                int value ;

                int index ;

                printf (" Enter the value :\ n ");

                scanf ("% d " , & value );

                printf (" Enter the position :\ n ");

                scanf ("% d " , & index );

                setValue ( arr , 10 , value , index );

                return 0;

}

2. createArray creates an int array of size len. It, then, initializes each element in the array with value.

int * createArray ( int len , int value ) {

                int * arr = ( int *) malloc ( sizeof ( int ) * len );

                memset ( arr , value , sizeof ( int ) * len );

                return arr ;

                }

int main ( void ) {

                int value ;

                int len ;

                printf (" Enter the value :\ n ");

                scanf ("% d " , & value );

                printf (" Enter the length :\ n ");

                scanf ("% d " , & len );

                int * arr = createArray ( len , value );

                if ( arr != NULL ) {

                                if ( len > 0) {

                                printf (" The first element is % d \ n " , arr [0]);

                                }

                free ( arr );

                }

return 0;

}

3. writeToFile asks the user to input a string and then write the entered string to “out.txt”.

void writeToFile () {

                char buffer [20];

                printf (" Enter the content :\ n ");

                scanf ("% s " , buffer );

                FILE * f = fopen (" out . txt " , " w ");

                fputs ( buffer );

                fclose ( f );

                }

int main ( void ) {

                writeToFile ();

                return 0;

}

4. sum returns the sum of two integers.

long long sum ( int a , int b ) {

                return a + b ;

                }

int main ( void ) {

                int a = 0;

                int b = 0;

                printf (" Enter a :\ n ");

                scanf ("% d " , & a );

                printf (" Enter b :\ n ");

                scanf ("% d " , & b );

                printf (" sum of a and b is % ld \ n " , sum (a , b ));

                return 0;

}

5. swap swaps the integer value stored in a and b.

void swap ( int * a , int * b ) {

                * a += * b ;

                * b = * a - * b ;

                * a = * a - * b ;

                }

int main ( void ) {

                int a = 0;

                int b = 0;

                printf (" Enter a :\ n ");

                scanf ("% d " , & a );

                printf (" Enter b :\ n ");

                scanf ("% d " , & b );

                swap (& a , & b );

                printf (" a is %d , b is % d \ n " , a , b );

                return 0;

}

Wil, Dave and Corinne are in a partnership as window repairers. Their business is called “Windows R Us”. Consider the following:

a. The business is run from an industrial shed which Dave owns. Dave pays for the upkeep of his shed, and the shed has remained basically unaltered since the business starting using it. However, due to rezoning of the area, the premises have substantially increased in value.

Explain the nature of the property in relation to the partnership and, if the premises is sold, whether profits must be shared.

b. Corinne purchases some expensive tinted glass on credit from a glass wholesaler –“Glass House”. Although Corinne actually wants the expensive tinted glass for her own private use (for a home she is building with her boyfriend Rove), she gives the impression to the salesperson at the Glass House that the purchase is on behalf of Windows R Us. Corinne has entered into this transaction on behalf of the partnership even though there was no express authority in the partnership agreement for Corinne to do so. Who will be liable for the debt incurred by Corinne?

c. (i) Dave and Corinne want to continue the business, but Wil is feeling like he wants to do something else with his life now, and thinks he would like to retire from the partnership. Advise Wil in relation to what action he should take regarding his liability for debts incurred by the partnership after he ceases to be a partner.

(ii) Unfortunately, before Wil makes up his mind as to whether he wants to retire, he dies suddenly. The partnership agreement does not include any provisions relating to the death of a partner.

Discuss the impact of Wil’s death on the partnership, and what happens with his share of the partnership.
