Question

alguien ayuda a hacer el procedimiento?
Realiza con notación científica los siguientes cambios de unidades: a) 25 km/h → m/s b) 70 dm/min → km/h c) 45 mg/ml → dag/m3 d) 5817 pm → μm e) 3,7 dam → Tm

Answer 1

a)  25 Km/h  a  m/s

m/s = 25 Km  x  1 hora  x  1000 m
         ``````````    ``````````    ````````````
           1 hora     3600 s       1 Km

m/s = 6.944

b) 70 dm/min  a  Km/h

Km/h = 70  dm      x   60 min   x     1  Km
            ````````````      ````````````    ````````````````
              1 min            1 hora        10000 dm

Km/h = 0.42

c)  45 mg/mL  a  dag/m3

dag/m³ =  45  mg  x  1000 mL   x   1000 L   x     1 dag
                ``````````     ``````````````    ```````````     ``````````````
                  1 mL              1 L           1 m³         10000 mg

dag/m³ = 4500

d) 5817 pm a μm

 1 μm   ------ 1 x 10⁶ pm
     x     ------    5817 pm

x = 0.005817 μm

e) 3.7 Dam a Tm

Tm = 3.7 Dam  x        1 Tm
                            ````````````````````` 
                             1 x 10⁻¹² Dam

Tm = 3.7 x 10¹²
