A tornado is a violent rotating column of air extending from a thunderstorm to the ground. The most violent tornadoes are capable of tremendous destruction with wind speeds of up to 300 mph. They can destroy large buildings, uproot trees and hurl vehicles hundreds of yards. They can also drive straw into trees.

When the E string of a guitar (frequency 330 Hz) is plucked, the sound intensity decreases by a factor of 2 after 4 s. Determine

zloy xaker [14]

Answer:

$Q=50.3$

Explanation:

From the question we are told that:

Frequency $F=330Hz$

Sound intensity drop $I_d=2$

Time $T=4s$

Therefore

Sound intensity Ratio

$\frac{I}{I_x}=\frac{1}{2}$

Generally the equation for Sound intensity is mathematically given by

$\frac{I}{I_x}=e^{-4\ \=t}$

$\frac{1}{2}=e^{-4\ \=t}$

$\=t =5.8s$

Generally the equation for Quality Factor is mathematically given by

$Q=2 \pi\frac{E}{\triangle E}$

$Q=2 \pi\frac{E}{\frac{E}{2*4}}$

$Q=50.3$

Sunshine Corporation is expected to pay a dividend of $1.50 in the upcoming year. Dividends are expected to grow at the rate of

grigory [225]

Answer:

$25

Explanation:

The computation of the intrinsic value of the stock is shown below:

As we know that

Intrinsic value or Price = Dividend ÷ (Cost of equity - growth rate)

where,

Cost of equity or ke is

= Risk free rate of return + beta × (Market rate of return - risk free rate of return)

= 6% + 0.75 × (14% - 6%)

= 12 %

So the intrinsic value is

= $1.50 ÷ (12% - 6%)

= $25

When bridges are built, special joints must be used because the material of the bridge shrinks, and without these joints, the ma

egoroff_w [7]

Answer:

Option D.

Explanation:

The correct answer is Option D.

The shrinkage of the bridge material is because of thermal contraction.

Thermal contraction and thermal expansion are the phenomena of the bridge material which takes place due to the change in temperature of the atmosphere.

When the temperature of the surrounding increases expansion of the bridge material takes place and when temperature decreases the contraction of the material takes place.

This phenomenon sometimes damages the structure because due to continuous expansion and contraction of materials strength of the bridge decreases.
