1.	26.What volumes should you mix of 0.2 M NaCl and0.1 M Cacl2, solution so that in resulting solutionthe concentration of positive lon is 40% lesserthan concentration of negative lon. Assumingtotal volume of solution 1000 ml.(A) 400 ml NaCI, 600 ml CaCL2(B) 600 ml NacL, 400 ml Cacl2(C) 800 ml NaC, 200 ml Cacl2(D) None of thesec
Answer» ANSWER: A particle has a displacement of 40M along OX in the first 5s and 30m perpendicular to OX in the NEXT 5s. The magnitude of average VELOCITY of the particle during the time internal of 10s is a) 6 ms–1 b) 7 ms–1 c) 8 ms–1 d) 5 ms–1 [ option d is the right answer.

Answer»

A particle has a displacement of 40M along OX in the first 5s and 30m perpendicular to OX in

the NEXT 5s. The magnitude of average VELOCITY of the particle during the time internal of 10s is

a) 6 ms–1 b) 7 ms–1 c) 8 ms–1 d) 5 ms–1 [

option d is the right answer.
