Answer 1

Answer:

1) 10N

2) 1000

3) 100N

4) b

5) 45*10kg

6) c

Answer 2

Answer:

Explanation:

Dyne is CGS unit. Newton is in SI unit. 

Therefore by definition of force we have: f=ma [2nd Law] 

[MLT^-2] 

Now ratio of si to cgs: 

metres x kilogram x seconds / centimeters x gram x seconds 

100cm x 1000 gm / 1 cm x 1 gm 

Therefore, ratio is 10^5 : 1

Kilograms (kg)  , Milligrams (mg)

1 kg    , 1000000 mg,

100 M dyne = 1000 N,

400 nm can be written s 400*10°m,

45*10 option C

Hope it helps.
