Answer:
b) It is impossible to tell without knowing the masses.
Explanation:
The temperature change of a substance when it receives/gives off a certain amount of heat Q is given by
![\Delta T= \frac{Q}{m C_s}](https://tex.z-dn.net/?f=%5CDelta%20T%3D%20%5Cfrac%7BQ%7D%7Bm%20C_s%7D)
where
Q is the amount of heat
m is the mass of the substance
Cs is the specific heat capacity of the substance
In this case, we have a hot piece of aluminum in contact with a cold piece of copper: the amount of heat given off by the aluminum is equal to the amount of heat absorbed by the copper, so Q is the same for the two substances. However, we see that the temperature change of the two substances depends on two other factors: the mass, m, and the specific heat, Cs. So, since we know only the specific heat of the two substances, but not their mass, we can't tell which object will experience the greater temperature change.
Weather is rain sun snow storm and warm and cold
The correct answer is GD Products collects receivables more quickly than AP Goods.
Analysts typically utilize the fixed asset turnover ratio (FAT) to gauge operating performance. This efficiency ratio assesses a company's capacity to generate net sales from its fixed-asset investments, specifically property, plant, and equipment (PP&E). It compares net sales (income statement) to fixed assets (balance sheet) (PP&E). Utilized as a net of accumulated depreciation is the fixed asset balance. A greater fixed asset turnover ratio shows that a business has utilized fixed asset investments to drive sales effectively. A greater ratio suggests that management is making better use of its fixed assets. No information can be gleaned from a high FAT ratio about a company's capacity to produce reliable earnings or cash flows.

Answer:
<em>Height = 5.65 km</em>
Explanation:
is the circumference or we can say measures the boundary of hemisphere of friction-less ice that he is sitting on.
So, the height will be = 2 x 3.14 x (30)^2 = 5654.7 m = 5.65 km
