lordkvng : N/8 is the mass that disintegrated, to find the mass left After disintegration, 8/8-n/8 =7N/8.. That's what u just did. and it's wrong. If ur theory is true, then how would we go abt this question below? The half-life of an element is 12hrs. If the initial mass is 50g, what mass will be left- after 2days? A. 3.125g B. 6.25g C. 12.5g D. 25g D

Guy,what U solved is incorrect!
Most times U dnt have to solve half lifes questions tongue

U think them out:DRobin is correct as the second questions showed Ur flaw.

TryAces:
option C

F=uv/u+v But v = u So f =u^2/2u U=2f U=2x12=24cm!

A. 2.17
B. 2.27
C. 0.17
D. 2.36

%change in qd/%change in p....
For %change in qd=>>(330000-220000)/330000×100==>110000/330000×100=33.33blahblahblah
•°•%change in qd(quantity demanded) iz 33.3%

For %change in p(price)==>>(75-65)/65×100==>dats 10/65×100==>>15.38dashdashdash.
So %change in p iz 15.4(rounded off)

Bringing dem together to get d coefficient of price elasticity
Should b 33.3/15.4=2.165%

So rounded off, e go give u 2.17%...
Fuçking A
cool
