Question

Hi..Anyone??
Evaluate each of the following and express each one with the correct SI units having an appropriate prefix.
1) (50mN)(6GN)
2) (400mm)(0.6MN)^2
3) (45MN^3)/(900Gg)

Answer 1

300MN
14.4 Gigaunits of momentum (1.44x10^10 kg*m/s)
101.25 teraunits of acceleration (1.0125*10^12 m/s^2)

Answer 2

Those are all the correct units, right?
Newton, Newton
meter, Newton
Newton, gram

Answer 3

Maybe,I'm not quite sure.

Answer 4

double check the question
does it say mN and GN for the first part?
mm and MN^2 for the second?
MN^3 and Gg for the third?

Answer 5

Yes,it is.

Answer 6

are the powers after the units? and are the values and units within parentheses?

Answer 7

That can change the answer

Answer 8

For num 2 yes the power of two is after the units and outside the brackets.
But the num 3 no.the power of three is after N.

guuh. the units will be a bit different then. Hang on a minute

Answer 10

and number 3's value will be different

Answer 11

Ok.

Answer 12

is 3 mega-(newton to the third)
or (mega-newton) to the third
