If x=At+Bt^2 where x is in kilograms and t is in hours, the unit of B will be?

Question

kg^2/hr, kg/hr^2, kg/hr, kg

Answer 1

Substituting the units in the formula we have:

kg = A(hrs) + B(hrs)^2

Analyzing the equation, gives us a clue that both of the terms on the right side of the equation are equal to kg units.

Thus we have:

kg = A(hrs)

and:

kg = B(hrs)^2

Therefore:

B=kg/(hrs)^2   <<<--------  ans.

Answer 2

kg/h^2

Answer 3

first convert the variables to unit so u get

Kg=a(hr)+b(hr^2)

final ans is in kg so

a(hr)=kg

and

b(hr^2)=kg

by solving

we get

a=kg/hr

and

b=kg/hr^2
