How does a arrow represent displacement

Physics
1 answer:
Lera25 [3.4K]4 years ago
4 0

Answer:

An arrow represents displacement. Because it's a vector quantity.

Vector quantity= Direction+Magnitude

When an arrow is put above a unit like

  • acceleration
  • displacement

it means that it's a vector quantity.

Hope this helps ;) ❤❤❤

The latent heat of vaporization for water at room temperature is 2430 J/g.
alukav5142 [94]

Answer:

1)   kinectic energy=7.26*10^-^2^0J

2)  V= 2.0m/s

3)  T=3.5*10^3K

4)  The Molecules do not burn because of the presences of hydrogen bond in place

Explanation:

From the question we are told that

latent heat of vaporization for water at room temperature is 2430 J/g.

1)Generally in determining the molar mass of water evaporated we have that

-One mole (6.02 x 10. 23 molecules)

-Molar mass of water is 18.02 g/mol

Mathematically the mass of water is give as

   

  M=\frac{18.02}{6.02*10^-^2^6}

  M=3*10^-^2^3g

Therefore

  kinectic energy=2430J/g*3*10^-^2^3g

 kinectic energy=7.26*10^-^2^0J

b)Generally the evaporation speed V is given asV= \sqrt{\frac{K.E*2}{m} }

Mathematically derived from the equation

\frac{1}{2} mv^2 =K.E

To Give

V= \sqrt{\frac{K.E*2}{m} }

V= \sqrt{\frac{7.26*10^-^2^0J*2}{3*10^-^2^3g} }

V= 2.0m/s

c)Generally the equation for velocity   Vrms=\sqrt{\frac{3RT}{M} }

Therefore

Effective temperature T is given by

      T=\frac{\sqrt{v}*m}{R}

where

     T=\frac{\sqrt{2.0m/s}*6.02*10^-^2^6}{0.082057 L atm mol-1K-1}

     T=3.5*10^3K

4) The Molecules do not burn because of the presences of hydrogen bond in place
