Answer 1

@Allofus

Answer 2

Do you mean that m/h is meters/hour
and thx

Answer 3

I think it means miles per hour but im not sure

Answer 4

It might be meters

Answer 5

if it were miles it would be mph but we can check both since its multiple choice

Answer 6

ok

Answer 7

Hmmm... does 8.889 × 10−6 cm/s mean 8.889 × 4 cm/s or \[8.889 × 10^{-6}\]

Answer 8

Oh sorry, im new to Open Study, all the x10^(number here)

Answer 9

so yes it is 10^-6

Answer 10

Answer 12

Yep so sorry I gotta eat real quick

Answer 13

...

Answer 14

OK
3.2*10^-4 * 60sec/1min = 0.0192
0.0192 *100 = 1.92
Doesn't work

Answer 15

Hmmm...

Answer 16

ok.. i found that 3.2 × 10−4 = 0.08888888888889

Answer 17

*10^-4

Answer 18

Huh?

Answer 19

I think it is either A or B

Answer 20

Answer 28

I just chose B. last question:
On average, a commercial airplane burns about 4.0 × 103 mL of gasoline per second. There can be as many as 5 × 103 airplanes in the air in the United States at any given time.

About how many gallons of gasoline are burned per hour by commercial airplanes in flight in the United States? (1 gal = 3,785.41 mL).

1.9 × 10 gal

Answer 33

3.2 × 10−4 m/h

change m and h to cm and s appropriately

Answer 34

m = 100 cm
h = 3600 s

Answer 35

@sheelo_mughal , yes thanks for that btw, but sadly not much help

Answer 36

3.2 (10^-4)
---------- cm/s

that should be self evident .....

Answer 39

i was responding to your orignal post, which is what i was tagged in for i believe

Answer 44

but why \[3.2\times 10^-4=0.00032\] am i right @Allofus

Answer 45

yep

Answer 46

so \[3.2\times 10^-4m/h=8.9\times 10^-17cm/s\]
