Which metal absorbs the greatest amount of heat energy

This question is incomplete but the completed question is in the attachment below. And the correct is b

Explanation:

Specific heat capacity can be defined as the amount of heat required to raise to raise 1 kg of a substance by 1 kelvin. Thus, this means that when the specific heat capacity of a substance is high, it takes more energy to increase the temperature of that substance. This also means that when different substances are subjected to the same amount of heat, the substance with the higher specific heat capacity will absorb less heat; for example at a beach, water has a very high specific heat capacity, thus when the sand in the beach is hot, the beach water is still relatively cold.

From the description above, it can be seen that the metal with the least specific capacity will absorb the greatest amount of heat, thus the metal is lead with the specific heat capacity of 0.129 J/(g. °C).

Preferred stock costs $117.92 today

Explanation:

Preferred dividend are the fix amount payment which represents the perpetuity, the company can repurchase the preferred share as it is callable.

The dividends of $20 represent a perpetuity beginning after 20 years. We have to discount all cash flows in the form of dividend for 20 years.

Perpetuity = Cash flow / Rate of return = $20 / 5.65% = $20 / 0.0565 = 353.98

Today's price = Perpetuity x ( 1 + r )-n = $353.98 x ( 1 + 0.0565 )^-20 = $117.92
