If the units of length and force are increased by four times, the unit of energy will be increased by:


ANSWER

$$1500$$%


SOLUTION

Energy $$=ML^{2}T^{-2}=Force\times length$$

$$L'=4L$$
$$F'=4F$$

% Increase $$=\dfrac{16(Force\times length)-(force\times length)}{(force \times length)}\times 100$$

                   $$= 1500$$%

Q1 Single Correct Medium
When $$CO_{2}(g)$$ is passed over red-hot coke it partially gets reduced to $$CO(g)$$. Upon passing $$0.5$$ litre of $$CO_{2}(g)$$ over red-hot coke, the total volume of the gases increased to $$700\ mL$$. The composition of the gaseous mixture at STP is :
  • A. $$CO_{2} = 200\ mL; CO = 500\ mL$$
  • B. $$CO_{2} = 350\ mL; CO = 350\ mL$$
  • C. $$CO_{2} = 0.0\ mL; CO = 700\ mL$$
  • D. $$CO_{2} = 300\ mL; CO = 400\ mL$$

Q4 Single Correct Medium
The accuracy of measurement also lies in the way the result is expressed. The number of digits to which a value is to be expressed is one digit more than number of sure numbers. Rules do exist to deal with number of digits after an operation is carried out on the given values. The error can be minimised by many trials and using the correct methods and instruments.
The number of significant figures can reduces in
  • A. Addition
  • B. Subtraction
  • C. Multiplication
  • D. Division
