What type of boat requires navigation lights?

oksian1 [2.3K]

All the boats that are operating from sunset to sunrise must have navigation lights.
Navigation lights are also for our safety, and it should be powered on after sunset to sunrise. Because at night due to darkness, if it is on, it is an indication that boat is there. Some of the boats which should have navigation lights are sailboats, powerboats, rowboats etc.

In the mass spectrum of pentane, the presence of a peak with m/z = 15 is most likely to the detection of:_________-

aliya0001 [1]

In the mass spectrum of pentane, the presence of a peak with m/z = 15 is most likely due to the detection of A) methyl radical cation that has been lost from the spectrum.

<h3>Mass Spectrum</h3>

The m/z ratios of any ions contained in a sample displayed against their intensities that forms a mass spectrum.

The height of the peaks in any kind of mass spectrum denotes the relative abundance of the various components in the sample, and each peak in a mass spectrum displays a component that a distinct m/z is in the sample.

<h3>How do mass spectra function?</h3>

Only when a molecule has been transformed into a gas-phase ion can a mass spectrometer calculate the mass of the molecule.

In order to do this, it gives molecules an electrical charge and transforms the flow of electrically charged ions that results into a proportional electrical current that a data system can subsequently read.

<h3>Give an example of the mass spectral range.</h3>

Whenever any molecules are ionized in an ionization box, many different kinds of ions have been created.

Assemble the electromagnetic spectrum by dragging each piece to the correct place on the wavelength scale.

777dan777 [17]

Answer:

long wave with a frequency of nos 10⁶ Hz, to radio waves

* order of 10⁸ Hz TV and FM

* in the 10⁹ to 10¹¹ Hz microwave range

* in the range of 10¹² to 10¹⁴ infrared waves, thermal energy

* in the range of 10¹⁴ visible light captured by humans

* for range 10¹⁵ to 10¹⁸ UV light

* in the range of 10¹⁶ to 10²⁰ X-rays

* for more than 10¹⁹ Hz cosmic rays

Explanation:

The electromagnetic spectrum is formed by transverse waves that are the oscillations of electric and magnetic fields

c = λ f

in general this spectrum is divided into range depending on the uses of the waves

from lower frequency to higher we have

* long wave with a frequency of nos 10⁶ Hz, corresponds to radio waves

* tv wave and modulated frequency, of the order of 10⁸ Hz, television and FM radio

* in the 10⁹ to 10¹¹ Hz microwave range

* in the range of 10¹² to 10¹⁴ infrared waves,

* in the range of 10¹⁴ visible light captured by humans

* for range 10¹⁵ to 10¹⁸ UV light

* in the range of 10¹⁶ to 10²⁰ X-rays

* for more than 10¹⁹ Hz cosmic rays
