11-Determine the specific heat of a material if a 12-g sample absorbed 96 J as it was heated from 20°C to 40°C. *
kompoz [17]

Answer:

c=0.4\ J/g^{\circ} C

Step-by-step explanation:

Given that,

Mass of a sample, m = 12 g

Heat absobed by the sample, Q = 96 J

It was heated from 20°C to 40°C.

We need to find the specific heat of a material. The heat absorbed by a sample is given by :

Q=mc\Delta T\\\\c=\dfrac{Q}{m\Delta T}\\\\c=\dfrac{96}{12\times (40-20)}\\\\=0.4\ J/g^{\circ} C

So, the specific heat of the material is 0.4\ J/g^{\circ} C.

Elden [556K]

Answer:

Step-by-step explanation:

An international company has 25,600 employees in one country. If this represents 19.3% of the company's employees, then the total number of employees that the international company has would be 100%.

To determine the actual value for 100%,

Let x represent the total number if employees that the international company has. Therefore

19.3/100 = 25,600/x

Cross multiplying,

19.3x = 25600 × 100 = 2560000

x = 2560000/19.3 = 132642.49

The total number of employees is approximately 132643
