Sav [38]

Answer:

The ladder is moving at the rate of 0.65 ft/s

Explanation:

A 16​-foot ladder is leaning against a building. If the bottom of the ladder is sliding along the pavement directly away from the building at 2 ​feet/second. We need to find the rate at which the top of the ladder moving down when the foot of the ladder is 5 feet from the​ wall.

The attached figure shows whole description such that,

x^2+y^2=256.........(1)

\dfrac{dx}{dt}=2\ ft/s

We need to find, \dfrac{dy}{dt} at x = 5 ft

Differentiating equation (1) wrt t as :

2x.\dfrac{dx}{dt}+2y.\dfrac{dy}{dt}=0

2x+y\dfrac{dy}{dt}=0

\dfrac{dy}{dt}=-\dfrac{2x}{y}

Since, y=\sqrt{256-x^2}

\dfrac{dy}{dt}=-\dfrac{2x}{\sqrt{256-x^2}}

At x = 5 ft,

\dfrac{dy}{dt}=-\dfrac{2\times 5}{\sqrt{256-5^2}}

\dfrac{dy}{dt}=0.65

So, the ladder is moving down at the rate of 0.65 ft/s. Hence, this is the required solution.

Which property of sound waves decreases as the square of the distance from the source increases?
Vitek1552 [10]

Answer:

Intensity

Explanation:

The intensity of a sound wave is equal to the ratio between to the power emitted by the source divided by the area of the spherical surface through which the wave propagates:

I=\frac{P}{4\pi r^2}

where

P is the power

4\pi r^2 is the area of the spherical surface

r is the distance from the source

As we see from the formula, the intensity is inversely proportional to the square of the distance from the source:

I\propto \frac{1}{r^2}

so, intensity is the correct answer.

the maximum displacement of an oscillatory motion is A=0.49m. determine the position x at which the kinetic energy of the partic
kipiarov [429]

Answer:0.4 m

Explanation:

Given

Maximum displacement A=0.49

The sum of kinetic and elastic potential energy is \frac{1}{2}kA^2

where k=spring constant

U+K.E.=\frac{1}{2}kA^2

when K.E.=U/2

K.E.=kinetic energy

U=Elastic potential Energy

\rightarrow \ U+\frac{U}{2}=\frac{1}{2}KA^2\\\rightarrow \ \frac{3U}{2}=\frac{1}{2}KA^2\\\rightarrow \ U=\frac{1}{3}KA^2\\\rightarrow \ \frac{Kx^2}{2}=\frac{1}{3}KA^2\\\\x=\sqrt{\frac{2}{3}}A\\x=0.4\ m
