Hi!

Option A is correct.

In cooking, convection is the phenomena that causes molecules with a higher energy at the bottom of a container to travel upwards, and the molecules at the top with a lower energy to sink to the bottom and replace them.

Mechanical convection describes this phenomena as a result of the application of an external force.

This phenomena is restricted to substances that are in liquid, or gaseous state, as molecules of a substance in solid state have a very restricted movement.

Hence, options B, C and D are incorrect.

Hope this helps!

John has just won the state lottery and has three award options from which to choose. He can elect to receive a lump sum payment

12345 [234]

Answer:

John should opt for the 30 annual end-of-the-year payments of $4 million as that gives the highest present of value of $49,636,164.73 as shown below.

Explanation:

The options are evaluated as follows:

Option 1 $46,000,0000 today

Option 2

The present of value of this option is calculated using the below formula:

Present value of annuity = ((1-(1/((1+i)^n))/i) X PMT

where i=rate=7%

n=10years

PMT=$7m

PV=((1-(1/((1+0.07)^10))/0.07) X 7000000

PV=$ 43,834,929.21

Option 3

The present value of this option using the formula in option 2 is:

PV=((1-(1/((1+0.07)^30))/0.07) X 4000000

PV=$49,636,164.73

Hence, the last option is preferable.

Why is a high-quality bond typically considered a lower-risk investment than a stock?

There is risk in owning a stock and many unknown variables.
In the case of bonds, you are guaranteed by the bond issuer that your principal and the agreed-upon interest will be paid at a defined time.
