Enthalpy is defined as the measure of energy in a thermodynamic system. The value of enthalpy is considered to be equal to the internal energy of the system and the product of pressure and volume. Calorimeter is usually used to obtain the value of enthalpy of a system. 
A coffee cup calorimeter is an effective way of measuring the enthalpy of a system because it is a constant pressure calorimeter. This means that, the heat that is measured in a coffee cup calorimeter is equivalent to the change in enthalpy; also its use result in little or no volume change to the system involved.

LiRa [457]

Answer:

The ending balance of Rogers​, ​Capital is $29,000

Explanation:

In this question, we use the formula of opening capital which is shown below:

Opening capital = Closing capital + drawings - profit earned + loss incurred - additional capital

where,

The profit earned = Revenue - expenses

                             = $41,000 - $26,000

                             = $15,000

And, the other items would remain the same

$25,000 = Closing capital + $11,000 - $15,000 + $0 - $0

$25,000 = Closing capital - $4,000

So, the closing capital = $25,000 + $4,000

                                     = $29,000

sergey [27]

Answer: He should decline production of the machine.

Explanation:

Analyzing the problem, we can determine if he should proceed or not by calculating the Net present value. That is present value of the machine in terms of perpetuity as it will be used forever and the cost incurred in its production.

Given the following ;

To manufacture $200 = 1 year, meaning

Amount or yearly payment = $200

Cost of machine = $2,000

Interest rate(r) = 11.5% = 0.115

Recall;

Present the value if perpetuity ;

(Payment per period ÷ rate)

= $200 ÷ 0.115 = $1739.13

Net present value = $1,739.13 - $2000 = - 260.87

Given the negative value of NPV, the cost outweighs the benefit, hence, he should decline.
