Please write your equations in an acceptable standard way. Do not use words like "and" and "by" in the equation.
Do you mean
P = A + B/t - C/(D+v) ?
What do you mean by a "dimensional formula?"
In the equation I have written,
A has dimensions of pressure
B has dimensions of (pressure)*time
C has dimensions of (pressure)/(velocity)
D has dimensions of velocity
yes i mean the above equation which u have written P=A+B/T-C/D+V.
The expression which shows how and which of the base quantities represent the dimensions of a physical quantity is called the dimensional formula.
plz sir help me
M - mass,
L - length,
T - time
Pressure P
Pa= N/m² = kg•m/s²m²=kg/m•s² =M•L^-1•T^-2 ,
A = M•L^-1•T^-2 ,
B= M•L^-1•T^-1,
C = M•L^-2•T^-1,
D =L•T^-1.
thank u mam.
i have not understood how n/m square it comes kgm/s2m2 and the cap symbol.
Newton is the unit of force
F= ma =>
m –> kg
a-> m/s²
N = kg•m/s² =M•L•T^-2
