15. The Energy possessed by a body by virtue<br>of its position or state is called :​
shepuryov [24]

Answer:

The Energy possessed by a body by virtue of its position or state is called Potential energy.

Mathematically potential energy can be written as,

Potential energy = mgh

Where 'm' represents mass of the body, 'g' represents gravity of the earth and 'h' represents height of body. Potential energy depends on the height, higher the hight from the surface of the earth, maximum will be the potential energy.

The wavelength of red light is 7 x 10^-7 meter. Express this value in nanometers
3241004551 [841]

  • The wavelength of the red light in "nanometer" is 7× 10^{2}

  • Wavelength is given as : 7×10^{-7} meter

  • 1 nanometer = (10^{-9} meter)

  • Let X= value of the wavelength in nanometer.

1 nanometer  = 10^{-9} meter

X nanometer = 7× 10^{-7}  meter

  • <em>If we Cross multiply</em>

X nanometer = (\frac{     7* 10^{-7} }{  10^{-9} })

X= 7×10^{2} nanometer

Therefore, the wavelength in "nanometer" is 7×10^{2}

This diagram represents the synthesis of nitrogen monoxide. Write a balanced equation of this chemical reaction. A) N2(g) + O2(g
ruslelena [56]
The only balanced equation is B. 

If you look at the equation and break it down you can see that in:

N_{2} + O_{2}→ 2NO

Starting from the left side of the equation there are 2 Nitrogen atoms, and 2 oxygen atoms as indicated by the subscript. 

To balance the equation, the number of atoms of each element in the right side equation should be equal to left. By putting the numerical coefficient of 2, you will distribute that to each element. So you will end up with 2 nitrogen atoms and 2 oxygen atoms on the left side of the equation. Thus, the equation is balanced. 

The answer again, is B.
