<h2>Answer:</h2><h3>Statement which describe the ethylene compound:</h3>

<em><u>There are two carbon atoms and 4 hydrogen atoms and there are total 6 covelent bonds in compound. 4 covelent bods are between hydrogen and carbon atom and two, in form of double bonds are between carbon bonds.It's structural arrangement shows that it is an unsaturated organic compound.</u></em>

Two hydrogen atoms are attached to one carbon and two H atoms to other carbon atoms.

Answer: Each hydrogen atom shares two electrons with each carbon atom, forming single covalent bonds, and the carbon atoms share four electrons between them, forming a double bond (two covalent bonds between the same pair of atoms).


Explanation:


This is a representation of the compound ethylene, C₂H₄, that shows the arrangement of the atoms (bonds):


   H   H

    |     |

   C = C

   |      |

  H    H


The single lines (vertical dashes in this particular case) represent single covalent bonds, which are the result of sharing one pair (two) electrons between the given atoms, and the double lines ( two horizontal dashes) represent double bonds, which means that the carbon atoms are sharing two pair (four) electrons.

A bat emitts a sonar sound wave (343 m/s) that bounces off a mosquito 8.42 m away
Varvara68 [4.7K]

The time lapse between when the bat emits the sound and when it hears the echo is 0.05 s.

From the question given above, the following data were obtained:

Velocity of sound (v) = 343 m/s

Distance (x) = 8.42 m

Time (t) =?

We can obtain obtained the time as illustrated below:

v = 2x / t

343 = 2 × 8.42 / t

343 = 16.84 / t

Cross multiply

343 ×  t = 16.84

Divide both side by 343

t = 16.84/343

t = 0.05 s

Thus, the time between  when the bat emits the sound and when it hears the echo is 0.05 s.

<h3>How does a bat know how far away something is?</h3>

A bat emits a sound wave and carefully listens to the echoes that return to it. The returning information is processed by the bat's brain in the same way that we processed our shouting sound with a stopwatch and calculator. The bat's brain determines the distance of an object by measuring how long it takes for a noise to return.

A cylinder is fitted with a piston, beneath which is a spring, as in the drawing. The cylinder is open to the air at the top. Fr
astraxan [27]

Answer:

x =  0.0734 m = 7.34 cm

Explanation:

First we shall calculate the area of the piston:

Area = \pi radius^2\\Area = \pi (0.028\ m)^2\\Area = 0.00246\ m^2

Now, we will calculate the force on the piston due to atmospheric pressure:

Atmospheric\ Pressure = \frac{Force}{Area}\\\\Force = (Atmospheric\ Pressure)(Area)\\Force = (101325\ N/m^2)(0.00246\ m^2) \\Force = F = 249.56\ N

Now, for the compression of the spring we will use Hooke's Law as follows:

F = kx\\

where,

k = spring constant = 3400 N/m

x = compression = ?

Therefore,

<u>x =  0.0734 m = 7.34 cm</u>

What term is used to describe all of the wavelengths of light waves?
Aneli [31]

Answer:

B.electromagnetic spectrum

Explanation:

Electromagnetic spectrum is used to  describe all of the wavelengths of light waves.Generally wavelength of the wave is denoted by λ.

Wavelength is the distance between two consecutive crest .Wavelength of the red color is minimum and wavelength of the violet color is maximum in the light  spectrum.

So the answer is B.

Electromagnetic spectrum
