Answer:
his experiment can show the movement of pollutants through the groundwater!
Explanation:
Answer: frequency =v/π= 3×10^8/6.9 ×10^-13=5×10^20
Explanation:) the relationship between the velocity and frequency of a wave is V=fπ ,where V=velocity of wave while the π or lander represents wavelength which was given in the question.f represents frequency of wave.velocity of waves differs,e.g sound waves has a velocity of 330m/s while electromagentic spectrum waves eg UV,infrared has a constant velocity called velocity of light =3×10^8.the question did not clarify the type of wave so I assumed it should be light. Which has a V= 3×10^8.so frequency was calculate d using velocity divided by wavelength (which. Was given).
Answer:
160.000 años corresponde a 16.000 décadas.
Explanation:
Para resolver correctamente el ejercicio debemos plantear la regla de tres simple de la siguiente manera:
1 década equivale a 10 años; A cuantas decadas equivalen 160.000 años?
1 década→10 años
x ←160.000 años
Debemos multiplicar 160.000 por 1 y luego dividir entre 10 ;
x=()=16.000 décadas; en notación científica sería 16x10^3.
Respuesta: 160.000 años corresponde a 16.000 décadas.
