Physics Formulas 10th Std

Some important formulas for 10th std physics (STATE)

Till 2nd Chapter now.. Other chapters coming soon..

Chapter - 1 - HEAT

The heat required to raise the temperature of a substance of
mass "m" kg and specific heat capacity "c" by "o" = Q
Q = mco

Mass = m = co/q
Specific heat capacity = c = mo/q
Rise in temperature = o = mc/q

Specific latent heat of fusion = Lf
Specific latent heat of fusion of an object with mass " m " = mLf

Specific latent heat of vaporization = Lv
Specific latent heat of vaporization of an object with mass "m" = mLv


Chapter - 2 - Heating and Lighting effects of electricity

 "I" is the current in ampere (A),
"V" is the current in volt (V)
"R" the resistance of the conductor in (OHM),
"t" the time in second (s)
"H" is the heat produced in joule (J)

H = I(Square)Rt
H = VIt

Time = t = H/VI
Resistance = R = V/I
Current In Volt = V = R x I
Current In ampere = I = R/V

Note : "x" is multiplication and  "/" is division (Square) is its 2nd power and (Cube) its 3rd power. "o" is "theta"..
