An Astronomer who made a list of 100 nebulae and galaxies that could

be mistaken for comets was Charles Messer's.

Charles Messier's was a very famous scientist in the field of Astronomy.

His research in appearance of Great comet filled spark to his passion

 of Astronomy. On January 21, 1759 he put his thought of wrong

 calculation of Delisle's and he described a faint glow resembling comet

 had been seen earlier. Then after, he discovered great comet near

 sword of Orion.

  There are various tales of Charles Messiers which put him forward

  towards his love of Astronomy.

How would you determine the volume of an irregular shaped object.
Archy [21]
You can use the displacement method or the eureka can so basically in the displacement can what you have to do is to put some water into a measuring cylinder and measure its volume before adding the irregular shaped object and then measuring the level of water which had been displaced and then eureka can you can check online

How has the farming industry been affected by the use of fossil fuels?
Mashutka [201]

Fossil fuels have led to an increase in food costs.

Explanation:

Buried organic material over million of years form combustible geologic deposits of organic materials called fossil fuels that can be converted crude oil, natural gas, or coal.

Fossil fuel are currently used as a source of energy in machine and equipment applied in the farming industry. Mechanization has been made possible due to this type of fuel availability thus larger farms have been prepared for cultivation.In addition, other processes such as planting,weeding and harvesting are currently performed by farming machines which are propelled by fossil energy. So in general, fossil fuels in the farming industry has led to increase in amount of crop harvested because more farms are under cultivation and farming process is now mechanized. However, due to use of machines and energy, the production cost has increased, thus to cover for this increased cost, the prices for food products increases, making the cost of food commodities to rise.

A bullet with a mass of 0.3 kg is fired out of a gun with a mass of 4 kg at 600 m/s. What is the recoil velocity on the gun?
slavikrds [6]

Answer:

According to the Conservation of Momentum,

Momentum of the gun = momentum of the bullet

M(gun)×V(gun)=m(bullet)×v(bullet)

4kg × V = 0.3kg × 600m/s²

V = (0.3 × 600)/4 = 45 m/s

The recoil velocity on the gun is <em><u>45 m/s</u></em>

<h3><u>45 m/s</u> is the right answer.</h3>

Light of a certain color has a wavelength of 4.8 x 10-7m. Determine the frequency and color of the light wave.
cluponka [151]

The frequency is 6.3\cdot 10^{14} and it is blue light

Explanation:

The relationship between the speed, the frequency and the wavelength of an electromagnetic wave is given by:

c=f \lambda

where

c=3.0\cdot 10^8 m/s is the speed of light

f is the frequency of the wave

\lambda is its wavelength

In this problem, the wavelength of the wave is

\lambda = 4.8\cdot 10^{-7} m

Therefore, its frequency is:

f=\frac{c}{\lambda}=\frac{3.0\cdot 10^8}{4.8\cdot 10^{-7}}=6.3\cdot 10^{14} Hz

The wavelength of this wave is

\lambda = 480 nm

And by looking at the table of the wavelengths of the colors, we notice that this corresponds to the blue light, which has a range of wavelength of

[450 - 495] nm
