Metric conversion ( convert )
Nikitich [7]

Answer:

13. 2g

14. 5000mL

15. 104,000m

16. 160mm

17. 5600000mg

18. 10hs

19. 0.250km

20. 1daL

Explanation:

13. 1000milligram (mg) = 1gram (g)

Hence, 2000mg = 2000/1000

= 2g

14. 1 litre (L) = 1000millilitre (mL)

Hence, 5L = 5 × 1000

= 5000mL.

15. 1kilometre (km) = 1000metre (m)

Hence, 104km = 104 × 1000

= 104,000m

16. 1 centimetre (cm) = 10millimeters (mm)

Hence, 16cm = 16 × 10

= 160mm

17. 1kilogram (kg) = 1000000 milligram (mg)

Hence, 5.6kg = 5.6 × 1000000

= 5600000mg

18. 1 second (s) = 0.01 hectosecond (hs)

Hence, 1000s = 1000 × 0.01

= 10hs

19. 1000metre (m) = 1kilometre (km)

Hence, 250m = 250/1000

= 0.250km

20. 1 centiliter (cl) = 0.001 Decaliter (daL)

Hence, 1000cl = 1000 × 0.001

= 1daL

Please help this is worth half of my grade! what letter represents the trough of the wave a,b,c,d,e
murzikaleks [220]

Hello good afternoon...God bless the answer to your following question is D

because...A crest point on a wave is the maximum value of upward displacement within a cycle. A crest is a point on a surface wave where the displacement of the medium is at a maximum. A trough is the opposite of a crest, so the minimum or lowest point in a cycle.
