To get the equation that describes l, we'll need to get the slope first: (15-3)/(5-2)=12/3=4r is perpendicular to l so it's slope is given by: -1/4To get b we calculate: -2=7*(-0.25) + b <=> b = -1/...

Endonucleases cut DNA at palindromic sites producing 'sticky ends'. The endonuclease cuts the plasmid DNA and the DNA to be inserted at the same palindromic site. The sticky ends of the plasmid DNA and th...

The strong nuclear force is repulsive for nucleon separations less than 0.5 femtometres but doesn't act at roughly 1 femtometre. It becomes attractive between 1 femtometre and 3-4 femtometres, afterwhich ...

Use conservation of momentum (p=mv).Momentum of Xenon = 0.13 kg × 30000 m s^-1 = 3900 kg m s^-1Momentum of spacecraft = 486 kg × vv=3900kgms^−1 /486kg=8.02ms^−1

Butan-2-ol can be produced as a result of reducing butanone with NaBH4. The hydride ion in NaBH4 is used as a nucleophile which can attack the C on the (C=O )either above or below the plane, depending on ...
