The ball with a mass of 1.5 kilograms is tied to the end of
Hunter-Best [27]

Solve the

potential energy at point B


PE = mgh


Where m is

the mass


G is the

acceleration due to gravity 9.8 m/s2


H is the height


PE = ( 1.5

kg) ( 9.8 m/s2) (0.5 m)


PE = 7.35 J



Solve the

velocity using the


KE = 0.5mv^2


Where ke is

the kinetic energy


M is the

mass


V is the

velocity


Since all

energy is converted to KE


So KE = PE



7.35 = 0.53(1.5)

v^2


V = 3.13 m/s

G you extracted your dna from cheek cells. the concentration of your dna sample is 250 ng/μl. the dna template for pcr should be
Karo-lina-s [1.5K]
You should mix 4µl of DNA sample and complete it with 96µl (100-4) of water.

You can figure this out by using  C1.V1 = C2.V2
C1 = 250 <span>ng/μl (Sample Concentration)
</span>V1 = ?          (the necessary volume to take from the DNA sample)
C2 = 10 <span>ng/μl (PCR concentration)
</span>V2 = 100 µl (total volume)

V1 = \frac{C2 . V2}{C1} = \frac{10 . 100}{250} = 4µl

For the water: 100µl (total volume) = 4µl + Water
Water volume = 96µl
