Each carbon atom in graphite is bonded to three other carbon atoms. These carbon atoms are linked by covalent bonds - which are very strong. Graphite is arranged in sheet like structures and between each ...

As temperature increases, the molecules involved in the reaction gain kinetic energy, increasing the chances of collision between the substrate molecules and the active sites of the enzymes, a step that i...

20% efficiency means that 20% of the electrical energy going into the lamp is transfered to light, and 80% of the energy is lost/wasted.

if (X-2) is a factor, f(2)=0

22^3-72^2+4*2+4= 16-28+8+4=0

therefore (x-2) is a factor.

2x^3-7x^2+4x+4=(x-2)(2x^2-3x-2)=(x-2)(2x+1)(x-2)

Because there are two forms of x , the form uv'+vu' must be used.

If y=sinx , dy/dx=cosx 

If y=e^kx , dy/dx=ke^kx

Therefore dy/dx=(sinx)(2e^2x)+(e^2x)(cosx)
