Answer: Carbon dioxide

Explanation:

The ocean helps in the absorption of carbon dioxide as phytoplankton absorbs carbon dioxide and performs the process of photosynthesis.

This process releases oxygen and consumes carbon dioxide by the process of diffusion.

More than normal level of carbon dioxide in water has lead to ocean acidification which is not good for the aquatic animals.

Which property of sound waves decreases as the square of the distance from the source increases?

Vitek1552 [10]

Answer:

Intensity

Explanation:

The intensity of a sound wave is equal to the ratio between to the power emitted by the source divided by the area of the spherical surface through which the wave propagates:

$I=\frac{P}{4\pi r^2}$

where

P is the power

$4\pi r^2$ is the area of the spherical surface

r is the distance from the source

As we see from the formula, the intensity is inversely proportional to the square of the distance from the source:

$I\propto \frac{1}{r^2}$

so, intensity is the correct answer.

Nimfa-mama [501]

Whenever an object is falling, its potential energy
is decreasing and its kinetic energy is increasing.

Olivia's potential energy is decreasing and her kinetic energy
is increasing as she moves toward the right side of the picture,
all the way from W, through X, to the bottom of the arc.

In which of the following situations or places would you want to reduce the

sashaice [31]

Answer:

Explanation:

The correct answer would be in the axle of the wheels while you ride your bicycle.

Options A, B, and C requires that the forces of friction is increased in order to have more control.

However, option D requires that there is a minimal frictional force in the axle of the wheels of a bicycle while riding so that a little effort would be required to keep the bicycle moving.

The lesser the friction, the lower the effort that would be needed to keep the bicycle moving and vice versa.
