DIMENSIONAL ANALYSIS 2023 Physics WAEC and NECO questions (WAEC past questions and answers)
This video explains some WAEC Physics past questions and answers for the West African Examination Council Exams (WAEC) on Dimensioning and Dimensional Analysis
Thiis video also gives clear and proper explanation on the concept of Dimensions of physical quantities including finding relationship between physical parameters for the 2023 West African Senior School Certificate Examination
It gives physics WAEC objective solution with detailed explanation without including the WAEC physics practical

The force,F, acting on the wings of an aircraft moving through air of velocity,v, and density,p, is given by the equation F=kv^xP^yA^z, where k is a dimensionless constant andA is the surface area of the wings of the aircraft.Use dimesional analysis to determine the values of x,y and z

😭😭😭😭 I have been struggling for quite a long time with physics... I wonder where has this channel been all this while.. But I felt relief on my first encounter to this channel... I believe my struggle is done

Tension is force\length meaning it dimensions MLT^-2

Surface tension = Force / Length = MLT^-² / L = MT^-²

Lovely to hear
• (2010) The critical velocity of a liquid flowing in a certain pipe is 3 m/s, assuming that the critical velocity v depends on the density p of the liquid. its viscosity mu, and the diameter d • of the pipe. i)Use the method of dimensional analysis to derive the equation of the critical velocity of the liquid in a pipe of half the diameter. ii) Calculate the value of critical velocity. Can somebody help please with (ii)

Simply assume d2 as half the first value of the first d1 and substitute d2 = 0.5d1
Please where can we see example question to try at your explanation
