1,500 mg = g

12,000 lb = T

6 tons

5,280 ft= mi

For problems 7-23, make each conversion.

23 yd to ft

69 feet

$2\frac{1}{2}$ mi to yd

8 in. to ft

51 in. to mi

3 qt to pt

6 pints

8 lb to oz

5 cups to tbsp

80 tablespoons

9 da to hr

$3\frac{1}{2}$ min to sec

$\frac{1}{4}=0\text{.}\text{25}$ L

18.57 cm to m

0.01961 kg to mg

19,610 mg

## Simplification of denominate numbers ( [link] )

For problems 24-31, perform the indicated operations. Simplify, if possible.

Add 8 min 50 sec to 5 min 25 sec.

Add 3 wk 3 da to 2 wk 5 da

6 weeks 1 day

Subtract 4 gal 3 qt from 5 gal 2 qt.

Subtract 2 gal 3 qt 1pt from 8 gal 2 qt.

5 gallons 2 quarts 1 pint

Subtract 5 wk 4 da 21 hr from 12 wk 3 da 14 hr.

Subtract 2 T 1,850 lb from 10 T 1,700 lb.

7 T 1,850 pounds

Subtract the sum of 2 wk 3 da 15 hr and 5 wk 2 da 9 hr from 10 wk.

Subtract the sum of 20 hr 15 min and 18 hr 18 min from the sum of 8 da 1 hr 16 min 5 sec.

7 days, 11 hours, 56 minutes, 7 seconds

For problems 32-43, simplify, if necessary.

What fields keep nano created devices from performing or assimulating ? Magnetic fields ? Are do they assimilate ?
why we need to study biomolecules, molecular biology in nanotechnology?
?
Kyle
yes I'm doing my masters in nanotechnology, we are being studying all these domains as well..
why?
what school?
Kyle
biomolecules are e building blocks of every organics and inorganic materials.
Joe
anyone know any internet site where one can find nanotechnology papers?
research.net
kanaga
sciencedirect big data base
Ernesto
Introduction about quantum dots in nanotechnology
what does nano mean?
nano basically means 10^(-9). nanometer is a unit to measure length.
Bharti
do you think it's worthwhile in the long term to study the effects and possibilities of nanotechnology on viral treatment?
absolutely yes
Daniel
how to know photocatalytic properties of tio2 nanoparticles...what to do now
it is a goid question and i want to know the answer as well
Maciej
Abigail
for teaching engĺish at school how nano technology help us
Anassong
Do somebody tell me a best nano engineering book for beginners?
there is no specific books for beginners but there is book called principle of nanotechnology
NANO
what is fullerene does it is used to make bukky balls
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
Tarell
what is the Synthesis, properties,and applications of carbon nano chemistry
Mostly, they use nano carbon for electronics and for materials to be strengthened.
Virgil
is Bucky paper clear?
CYNTHIA
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
NANO
so some one know about replacing silicon atom with phosphorous in semiconductors device?
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Harper
Do you know which machine is used to that process?
s.
how to fabricate graphene ink ?
for screen printed electrodes ?
SUYASH
What is lattice structure?
of graphene you mean?
Ebrahim
or in general
Ebrahim
in general
s.
Graphene has a hexagonal structure
tahir
On having this app for quite a bit time, Haven't realised there's a chat room in it.
Cied
what is biological synthesis of nanoparticles
what's the easiest and fastest way to the synthesize AgNP?
China
Cied
how did you get the value of 2000N.What calculations are needed to arrive at it
