This is an online platform which was created to help students solve their physics and chemistry problems online. This is online tutorship whereby you can chat with tutors through facebook to ask and solve problems especially calculations. This is applicable to any UTME, Post UTME student, Pre-degree and even 100 level students. You can ask your questions and also contribute. This is powered by www.mycashpayer.com.

You can drop your email address here for more details. You shall get information to your inbox as soon as possible.
You can as well send email to kayjegs@yahoo.com or send a sms only to 08090617157 to confirm interest. Thanks

EXAMPLE: CAN YOU SOLVE THIS:
PHYSICS:
An object of mass 60g and density 10g/cm3 is suspended by thread and lowered until half of its volume is immersed in a liquid of density of 0.80g.cm3. What is the tension in the thread?

CHEMISTRY:
A hydrocarbon P on combustion gives 0.604g of CO2 and 0.216g of H2O. The mass of a molecule of P is 56g. Determine the molecular formula of P (O = 16, C = 12, H = 1).


More on request...

if F=force,t=time find the dimensions of a and b from F=at+bt^2 where a and b are constants

Chemistry answer --> C2H4O6

A rocket is fired from the surface of the earth..At what velocity must it be fired to escape from gravitational pull...Take the radius of the eart to be 6370km and g=9.8m/s^2.

V = (ROOT 2GR) . 6370km = 1769m . Root 2 * 9.8 * 1769. V =186.21m/s.

Did you just say 6370km=1769m

Yea wrong conversion. Wl get bak later
