Identify the two atmospheric layers that contain air as warm as 25◦ C

En un m.A.S. La amplitud tiene un valor de 10 centimetros y el periodo es de 2 segundos calcular el valor de la velocidad de 0.8

Ivanshal [37]

Answer:

v1=18.46m/s

v2=29.8cm/s

Explanation:

We know that

$A=10cm\\T=2s$

the equation of the motion is

$x=Acos(\omega t)\\$

we can calculate w by using

$\omega=\frac{2\pi}{T}=\frac{2\pi}{2}=\pi$

Hence, we have that

$x=10cm*cos(\pi t)\\$

the speed will be

$v=-\omega*Asin(\omega t)\\|v(0.8)|=|\pi*10cm*sin(\pi *0.8)|=18.46\frac{cm}{s}\\|v(1.4)|=|\pi*10cm*sin(\pi *1.4)|=29.8\frac{cm}{s}$

hope this helps!

What are aerial plants

Alex_Xolod [135]

Answer: Aerial plants is plants that lives in air or wind the wind serves as the water of the plants. Most aerial plants are found in tropical and equatorial regions of the world. In evergreen rain forests, the foliage is so thick that some plants have evolved aerial roots to allow them to absorb more sunlight. The development of aerial roots is

thus an evolutionary process.Aerial roots are often thick and spread around the parent tree. The Banyan tree can have several aerial roots as it gets older.

S To minimize neutron leakage from a reactor, the ratio of the surface area to the volume should be a minimum. For a given volum

goblinko [34]

To minimize neutron leakage from a reactor, the ratio of the surface area to the volume should be a minimum. For a given volume V , ratio for (c) a parallelepiped of dimensions × 2 a will be $\frac{6.29961}{c^\frac{1}{3} }$

What will be the ratio of surface area and the volume of the parallelepiped

We will proceed by stating the equations of the surface area and the volume of each shape, and then identifying each of the surface area and the volume, we will take their ratios, and as it is asking for the shape which has the minimum surface area to volume ratio, therefore at some given volume, $V=const$ .

The parallelepiped whose dimension is given as

$2a,a,a$

the surface area and the volume is given respectively by:

$A=2(2a \times a)+2(a \times 2a)+2(a \times a)=10a^{2}$

$V=2a^{3}$

Let the volume be equal to the constant c, we get:

$V=c=2a^{3}\\a=(\frac{c}{2} )^\frac{1}{3}$

Hence the ratio is given by:

$\frac{A}{V} =\frac{10a^{2}}{2a^{3}}=\frac{5}{a}$

Calculating the constants, by substituting the value of $a$ in (3), we get:

$\frac{A}{V}=\frac{6.29961}{c^\frac{1}{3} }$

Half Time At 3:00 the hour hand and the minute hand of a clock point in directions that are 90.0

jenyasd209 [6]

Answer:

3 : 08 : 10.9

Explanation:

assuming a 12 hour clock

angular velocity of the hour hand is 2π/(3600(12)) rad/s

angular velocity of the minute hand is 2π/3600 rad/s

difference is 2π/3600 - 2π/(3600(12)) = 11(2π/(3600(12)) rad/s

45° = π/4 radians

This angle is covered in a time of

π/4 rad / 22π / (3600(12)) = 900(12) / 22 = 490.909090... s

or about 8 minutes 10.9 s
