emmyeuler1: Mr Calculus i solved ur question twice and i was banned 4 dat

Mr Calculus: and y is that bro?

Mr Calculus: and y is that bro?

emmyeuler1: is antispam bot on this thread dat use to ban people if you paste solutions on dis thread at certain tymz....are u still interested in d solution to ur question?

akanji2013: Calculate the energy stored in an inductor of 2H carrying a current of 5A.

Ai-bi-ke:
....20joules

akanji2013: A force of 20N is used to push a box of mass 1kg up an inclined plane, if the plane is at 30degrees to the horizontal calculate it's efficiency.

akanji2013: pls show ur workings

Ai-bi-ke:
......energy=IL^2,E=5*2^2=20J

okorocha22: wats ur course bro?....add me,on 2go 'olise35' make we chat

Calculusf(x):
You guys are doing great here ooo...let me sit and wait my ogas as they are doing their magic

t.boy007:
(math):
Factorize:
x^4 - 8
(physics):
when an ebonite is rubbed with fur,what will be the charge of the two substances respectively?
(chemistry):
what is the substance used to test for ALKANOLS?

Calculusf(x):
...x^4-8...x^4-8-8+8...x^4-16+8...(x^2)^2-4^2+8...since a^2-b^2=(a+b)(a-b)...therefore...(x^2+4)(x^2-4)+8...since x^2-4 is also a difference of two squares...(x^2+4)(x^2-2^2)+8...(x^2+4)(x+2)(x-2)+8.....(2)...when an ebonite rod is rubbed with fur...the ebonite is negatively charged while the fur is positively charged coz electrons are transferred from the atoms of the fur to the atoms of the ebonite...since the ebonite gain an electron,then it becomes negatively charged and fur which lose electron will become positively charged...(3)...hmmm.it can be differentiated from others by using lucas reagent

Mr Calculus: where is oga emmyeuler?

Mr Calculus: A quest 4 my guruz in the house,,need ur assistance::
Two men are standin on the same side of a high wall and at thesame distance from it such that they are 400m apart.When one man fires a pistol,the other hears the first report 1.2s after seein d flash and d second report 0.5s after the first.calculate
(a)velocity of sound in air
(b)perpendicular distance of the men from the wall

Mr Calculus: a stone is projected upwards with a velocity of 20m/s.Two seconds later a second stone is similarly projected with the same velocity.When the two stones meet,d second one is rising at a velocity of 10m/s.neglect air resistance .calculate the length of time the two stone is in motion b4 they met.?..
