Answer:
The answer is C.
Explanation:
An ion is unlike a neutral atom in the fact that it has a charge. Because electrons are negatively charged, an atom becomes more positive if electrons are lost.
The nitrogen fixation is the process of conversion of nitrogen gas into a usable form.
Answer: Option 3
<u>Explanation:
</u>
The nitrogen fixation is the process where the nitrogen gas present in air gets trapped and converted into ammonia or other nitrogenous compounds. This is the first step of nitrogen cycle.
The atmospheric nitrogen will get absorb in soil and gets converted to either ammonia which acts as nutrition for plants or other nitrogen related compounds which acts as fertilizers.
So, the nitrogen which get converted to usable stable form of nitrogen compounds can be used by plants, microorganisms and other organisms in the ecosystem.
Explanation:
Incident light makes an electron oscillate. The electrons emit light or absorb the light, collide with other electrons, thereby converting light energy to more internal energy. and convert it to heat.
Light wave of a given frequency is incident on a material with electrons having the same vibrational frequencies, then electrons absorb the energy of the light wave and transform it into vibrational motion.
8.0-3.0=5.0metres in the x direction
7.0-5.0=2.0 metres in the y direction
Use Pythagoras
25+4=29
![\sqrt[2]{29 }](https://tex.z-dn.net/?f=%20%5Csqrt%5B2%5D%7B29%20%20%7D%20)
=5.39metres in 2secs
=2.645m/s at an angle of 68.2 degrees to horizontal.... see below!
tan-1 angle = 5/2
angle=68.2 degrees
