Answer:

79.59 units ³

Step-by-step explanation:

As we know, Volume of cone = ⅓πr²h

<u>Given</u>

r = 2 units

h = 19 units

π= 22/7

.

\frac{1}{3}  \times  \frac{22}{7}  \times 2 \times 2 \times 19

= 79.59 units ³

Which of the following statements is true? a. Bonds have more risk than stocks, but offer more return. b. Stocks have more risk
Ipatiy [6.2K]

Answer:

Option: b is correct.

( Stocks have more risk than bonds, but offer more return).

Step-by-step explanation:

Bonds are debts while stocks are stakes of ownership in a company.  

Bonds pay a fixed rate of interest, and guarantee principal payment at the end of the term, they're generally considered to be safer than stocks. That doesn't mean bonds are 100% safe.

<em>" Most investment professionals consider bonds a safe component of portfolios. They're supposed to provide the stability and certainty that stocks can't "</em>

<em>" In bond we have a fixed interest whereas in stock the rates could go much high "</em>

Hence, option b is correct. ( Stocks have more risk than bonds, but offer more return).

the probability density for a particle in a box is an oscillatory function even for very large energies. Explain how the classic
77julia77 [94]

Answer:

This is achieved for the specific case when high quantum number with low resolution is present.

Step-by-step explanation:

In Quantum Mechanics, the probability density defines the region in which the  likelihood of finding the particle is most.

Now for the particle in the box, the probability density is also dependent on resolution as well so for large quantum number with small resolution, the oscillations will be densely packed and thus indicating in the formation of a constant probability density throughout similar to that of classical approach.

A 4 meter ladder leans against a house forming a
Ket [755]

Answer:

2.meters

Step-by-step explanation:

Lenght of ladder = 4 m

θ = 30°

To obtain h;

Using Pythagoras rule :

Sinθ = opposite / hypotenus

Hypotenus = 4 ; opposite = h

Sin 30 = h / 4

0.5 = h / 4

h = 0.5 * 4

h = 2 m

Hence, distance between th efoot of ladder and the base of the wall is 2 m
