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.

In an experiment, a torque of a known magnitude is exerted along the edge of a rotating disk. The disk rotates about its center.

lisabon 2012 [21]

Answer:

B) The amount of time the torque is applied to the disk, because the time interval is related to the angular impulse of the disk.

Explanation:

Angular impulse = Torque x time

= change in angular momentum

So,

Torque x time = change in angular momentum

change in angular momentum = Torque x time

Torque is already known .

Hence to know the change in angular momentum what is needed to know is time duration of torque acting on the body .

You set out to design a car that uses the energy stored in a flywheel consisting of a uniform 80-kg cylinder of radius r that ha

Oliga [24]

E = 300km * 2000J/km = 600000J

The rotational energy is given by:
E = 0.5 * I * ω²

I for a uniform cylinder is given by:
I = 0.5 * m * r²

Resulting equation:
E = 0.25 * m * r² * ω²

Given values:
ω = 430 rev/s = 430 * 2π / s
E = 600000

Solve for r.

Explain how air masses form and how they help redistribute energy on earth surface

Anna35 [415]

Air masses form because of all the moisture in the air, and they redistribute energy on the Earth's surface because of the Sun's uneven heating on the Earth allowes more energy to Earth.

Convert 1,000,000 to scientific notation

riadik2000 [5.3K]

For this case we have the following number:
1,000,000
We note that the number has 7 significant figures.
To write it in scientific notation we must write the number as follows:
 $a * 10 ^ b
$
 Where,
a: first significant figure
b: Exponent that represents the rest of significant figures.
Rewriting the number we have:
 $1000000 = 1 * 10 ^ 6
$
 Answer:
1,000,000 to scientific notation is:
 $1 * 10 ^ 6$
