Un buzo que nada en las profundidades despide pequeñas burbujas de aire¿Aumenta disminuye o permanece igual el tamaño de las bur
alekssr [168]

Answer:

Al ascender las burbujas van aumentando de tamaño.

Explanation:

Las burbujas que produce el buzo debajo del agua son pequeñas moléculas de dióxido de carbono gaseoso producto de la respiración del mismo.

Ahora, a medida que las burbujas suben a la superficie, la presión que sufren estas (Presión debido al agua), es menor conforme van ascendiendo debido a la ley de Boyle: A medida que la presión aumenta, el volumen va disminuyendo.

Esto significa que al ascender las burbujas van aumentando de tamaño debido a que la presión que sufren estas es menor que cuando están a mayores profundidades.

1.0 x 10^2 m what is the frequency of the waves
MAVERICK [17]

Answer:

f = 3 × 10⁶ Hz

Explanation:

Given data:

Wavelength of wave = 1.0 ×10² m

Frequency = ?

Solution:

Formula:

Speed of light = wavelength× frequency

Frequency = speed of light / wavelength

speed of light = 3× 10⁸ m/s

f = 3× 10⁸ m/s / 1.0 ×10² m

f = 3 × 10⁶ s⁻¹

s⁻¹ = Hz

f = 3 × 10⁶ Hz
