Answer:

Explanation:

For water, the temperature needs to be a little over zero degrees Celsius (0C) for you to melt. If you were salt, sugar, or rock, your melting point is higher than that of water.

The "break-even" interest rate for year n that equates the return on an n-period zero-coupon bond to that of an n - 1 - period z

kozerog [31]

The "break-even" interest rate for year n that equates the return on an n-period zero-coupon bond to that of an n - 1 - period zero-coupon bond rolled over into a one-year bond in year n is defined as the forward rate.

A forward rate is a specified price agreed by all parties involved for the delivery of a good at a specific date in the future. The use of forward rates can be speculative if a buyer believes the future price of a good will be greater than the current forward rate. Alternatively, sellers use forward rates to mitigate the risk that the future price of a good materially decreases.

Regardless of the prevailing spot rate at the time the forward rate meets maturity, the agreed-upon contract is executed at the forward rate. For example, on January 1st, the spot rate of a case of iceberg lettuce is $50. The restaurant and the farmer agree to the delivery of 100 cases of iceberg lettuce on July 1st at a forward rate of $55 per case. On July 1st, even if the price per case has decreased to $45/case or increased to $65/case, the contract will proceed at $55/case.

To extract the forward rate, we need the zero-coupon yield curve.

We are trying to find the future interest rate $r_{1,2}}{\displaystyle r_{1,2}$ for time period

$(t_{1},t_{2})}(t_1, t_2), {\displaystyle t_{1}}t_{1$ and $t_{2}}t_{2$ expressed in years, given the rate $r_{1}}r_{1$ for

time period ${\displaystyle (0,t_{1})}(0, t_1)$ and rate $r_{2}}r_{2$ for time period ${\displaystyle (0,t_{2})}(0, t_2)$ . To do this, we use the property that the proceeds from investing at rate $r_{1}}r_{1$ for

time period ${\displaystyle (0,t_{1})}(0, t_1)$ and then reinvesting those proceeds at rate

$r_{1,2}}{\displaystyle r_{1,2}$ for time period ${\displaystyle (t_{1},t_{2})}(t_1, t_2)$ is equal to the proceeds from

investing at rate $r_{2}}r_{2$ for time period ${\displaystyle (0,t_{2})}(0, t_2)$ .

Which of the following correctly describes a compound? The atoms are bonded together, and the compound has different physical an

grandymaker [24]

A chemical compound can be described as substance composed of atoms from more than one element held together by chemical bonds in a fixed stoichiometric proportion. A compound has different physical and chemical properties from its constituent elements.

For example : compound water is made up of H and O bonded together and it has different properties from O and H.

Thus, among the given options, the one coreectly describing a compound is

a) The atoms are bonded together, and the compound has different physical and chemical properties than the individual elements.

Tom [10]

Answer:

A: plants give off water vapor as a waste product as they process energy

Explanation:

Evapotranspiration in plants is defined as the process whereby water is evaporated from its leaves through transpiration during the process of photosynthesis. Different factors like wind, humidity, temperature and availability of water could make it vary.

Comparing all the options, to this definition, the correct answer is Option A.
