Hey guys,
I will be writing jamb this year and since I know how helpful Nairaland can be, i've decided to create a thread where fellow jambites can come together and express their thoughts, read and practice questions, drop tips on how to smash the exam etc.........

where dis girl run go sef

OK, to keep the thread lively.....

Evaporation depends on...
i. Relative humidity
ii. Saturated vapour pressure
iii. External pressure
iv. Atmospheric pressure

which combination of the above is/are correct

a. i and ii
b. i,ii and iv
c. ii and iv
d. i and iv

A piece of radioactive material contains 10^20 atoms. If the half-life of the material is 20 seconds, the number of disintegrations in the first second is
a. 3.47 x 10^18
b. 6.93 x 10^18
c. 3.47 x 10^20
d. 6.93 x 10^20

Which one of these is correct
during floatation?

a. upthrust = Wa/Rd
b. upthrust = (Rd + Wa)/Rd
c. upthrust = Rd/Wa
d. Upthrust = (Wa - Rd)/Wa

Wa = Weight in air
Rd = Relative density

[quote author=NeuroVic post=112352891]A piece of radioactive material contains 10^20 atoms. If the half-life of the material is 20 seconds, the number of disintegrations in the first second is

b. 6.93 x 10^18
c. 3.47 x 10^20
d. 6.93 x 10^20[/


numba of disintegration,∆n at the time interval at nah
- ∆N = N∆t
But n is the number of atoms present at the time ie t
But^ = (0.693)/t
=0.693 ÷ 20
=0.0347


So ∆N suppose be 0.0347 × 10^20
= 3.47 × 10 to power 18..
