The complexity and variety of organic molecules is due to
Anastaziya [24]

Answer:

Due to the chemical versatility of carbon atoms

Explanation:

Carbon is a very important element and it is commonly found in many varieties of chemical compounds. They are also found to be present in space in various amount. It is often considered to be versatile because they are capable of forming single, double, as well as triple bonds. This enables them to make single and branched chains. They also form ring chains when combined with other atoms of carbon.

It is because of this versatility of carbon atoms, there forms complex variety of organic molecules.

Kepler's 3 laws with formula centerpital<br> forces
madreJ [45]

Answer:

Kepler's Third Law

T = 2 π r 3 G M E . T = 2 π r 3 G M E . For an ellipse, recall that the semi-major axis is one-half the sum of the perihelion and the aphelion. For a circular orbit, the semi-major axis (a) is the same as the radius for the orbit.

A typical tornado can be envisioned as a cylinder of height 640 m, with a diameter of about 230 m (note: the visible funnel clou
Evgen [1.6K]

Answer:

16771720740.20324 J

Explanation:

\rh0 = Density = 0.97 kg/m³

V = Volume = \pi r^2h

d = Diameter of cylinder = 230 m

r = Radius = \frac{d}{2}=\frac{230}{2}=115\ m

h = Height of the cylinder = 640 m

v = Velocity of cylinder = 51 m/s

Mass of object is given by

m=\rho V\\\Rightarrow m=0.97\times \pi 115^2\times 640\\\Rightarrow m=25792727.013\ kg

Moment of inertia of a cylinder

I=\frac{1}{2}mr^2\\\Rightarrow I=\frac{1}{2}\times 25792727.013\times 115^2\\\Rightarrow I=170554407373.4625\ kgm^2

Angular speed

\omega=\frac{v}{r}\\\Rightarrow \omega=\frac{51}{115}\ rad/s

Kinetic energy is given by

K=\frac{1}{2}I\omega^2\\\Rightarrow K=\frac{1}{2}\times 170554407373.4625\times \left(\frac{51}{115}\right)^2\\\Rightarrow K=16771720740.20324\ J

The kinetic energy contained by the tornado is 16771720740.20324 J
