Multiplication errors |
| Answer» Actual values* and these are*. Sorry for mistake<br>if we have to find density, then the formula for density is mass per unit volume. d = m/vThe equation will be - DELTA d/d = DELTA m/m + DELTA v/vHere, DELTA d represents the error in density and d represents the actual value of density. Similarly, DELTA m means error in mass whereas m means actual mass and DELTA v means error in volume and v means actual volume. In these questions, 4 values are often given which are of mass and volumes including their errors.These values are written in the form of x + or - delta x where delta x is the error and x is the actual value.So, we can find the actual value of density by putting the actual valued of mass and volume given in the question in the formula density(d) = mass(m)/ volume (v). These is applicable to division and multiplication both. | |
