What are you looking for?

Syllabus

speed c: light in vacuum to the speed of light in glass,)is found to vary with the

wavelength µ = A + B/λ2

where A and B are constants. Using the principle of homogeneity determine the

dimensions and SI units of A and B

Please explain each and every step with reason as i coudn't understand the steps of this in NCERT

If P,Q,R are physical quantities, having different dimensions, which of the following combinations can never be a meaningful quantity (a) (P-Q)/R (b) PQ-R (c) PQ/R (d) (R+Q)/PWhat method should we use to find dimension of a quantity which is part of a trigonometric function?

for example,

Position of a body is represented by r = A sin Bx + C sin Dt where x is in metres and t is in seconds. What is the dimension of B/D?

If possible can you show a few more examples of solving such questions?

^{2})/at where E is energy, x is distance and t is time.I attended the unit and measure test- i could get only 66% - need your help to enhance my score..

Want your feedback on the area of improvement.

Please show step by step working

Given X=a

^{2}b^{1/3}/ c^{3.}find the error percentage of X if the percentage of errors in a,b,c are 2,4, and 5 respectively.sir please clarify my doubt.

pls answer the question with the same values , don'thyperlink a sum of the same kind.

Thank u sooo much
