Yes both are required. For Units -- They are to differentiate entities such as Pressure, Force, Power etc. Else it would be difficult to denote them and use them in real life. For Estimation -- Before udnerstanding this, lets be clear that Physics is considered as Math in applied way. Numbers are foundation in math where we have irrational numbers (Which exist but cant be located on numerb line) so thats the reason we estimate approximate values. In Physics too in division and finding roots we have to estimate frequently. Ex -- Pressure = Force/ (Area * Are) , so Area = (F/P)^0.5 . now it has high chances of being irrational number so we will have to estimate. Similarly while dividing by 3, 7, 9, 11 etc we have to estimate read less

Yes. Estimation (rough calculation) is required for practice. And units are most important part of numerical answer.

yes they are required because while you are taking readings for a certain experiments then you have to record some rough readings to estimate the true value and without units physics is nothing, units is the basic need of measurement in physics

In a class test, the sum of marks obtained by P in Mathematics and Science is 28. Had he got 3 more marks in Mathematics and 4 marks less in Science, the product of marks obtained in the two subjects would have been 180? Find the marks obtained in two subjects separately.
Let the no. of marks obtained in Maths = x & no. of marks obtained in Science = 28-x It is given that (x+3)(28-x-4) = 180 (x+3)(24-x)=180 24x-x2+72-3x=180 x2-21x+108 = 0 x2-12x-9x+108=0 x(x-12)-9(x-12)=0 (x-9)(x-12)=0 therefore...

Two wires one of copper and other of manganin, have equal lengths and equal resistances. Which wire is more longer?
Resistance : ?l/A Resistivity ? of manganin is much greater than that of copper, therefore to keep same resistance R, for same length of wire, the manganin wire must be thicker.
