To the best of my knowledge


let's start by.......... Density=mass/volume

so....500kgm³=5×10^-⁴/volume


Then.....volume=5×10^-⁴/500 =1×10^-6m³


Thickness= volume/area

=1×10^6/0.5×1000drops of water
= 2×10^9cm.......Final answer

Erflog:
we're waiting Sir

ISISs:
I greet everybody here!! My name is ISISs.

Pes13:


Another guru here.

Pes13:


U got the stepping but missed the last stage
1x 10^-6/0.5x 1000 = 2 x 10^-9m


When it is time to talk on studying efficiently, I will discuss why its preferable to get 1 calculation right over 4 non calculation question in jamb physics.

Pes13:


Mtn network is really frustrating here.

In other not to get stuck , I am waiting till tomorrow evening for a Wi-Fi network.

There are lot I want to discuss.

Why a student will answer 90% of questions in jamb and in the end hardly score 60%, and another student can intelligent answer 70% of the questions and end up scoring 82%.

sir I prefer answering physics calculation than physics theory, the exam I did this year (jamb), I had less than 13 calculations in physics, rest are theory, I ended up scoring 43 in physics, I was amazed because I didn't expect that much,since they didn't gv me what i like,
Is this a problem?
Won't it affect me again?
I notice i easily memorise formula and remember quickly, but when am reading stuffs like Waves, photoelectrons etc,I easily forget.
am experiencing this only in physics.
what should I do to be at least GOOD in answering theoretical questions?

What amount of current would pass through a 10 Ω coil if it takes 21s for the coil to just melt a lump of ice of mass 10g at 0o C if there are no heat losses? (Latent heat of fusion of ice = 336 Jg-1 ).

boyejo123:


sir why is the area=0.5*1000
I think they said ONE OF THE THIN FILM FORMS 0.5m,find the thickness of that ONE THIN FILM and not all,pls explain sir

Salarys:

D

Reason: if you can’t put up with something or bear something, then it is said to be negative.. Smell is negative while the rest options there are positive.
I stand to be corrected though

48noble ,I caught you...I'm already on my duty post

ISISs:
Folks planning to disgrace english language come 2018 jamb..
Dont let go off THEHISTORIAN!!
He's my best book in that aspect.

ISISs:

Loolss.
U never seize to crack me up..
Na so I go catch u for za oza room on nairaland..

48noble:



na mistake?

Pes13:


We were given mass of 1000 drop, that is why we need to calculate using the whole drop


Moreover , 1 drop and 1000 drops have the same thickness only different area and volume.
