Which increases the rate of soil formation?

Carmen is heating some water and trying to measure the temperature of water using a Celsius thermometer. Which measurement can s

andrew-mc [135]

<u>100° C</u> she can expect once the water begins to boil.

<u>Option: B</u>

<u>Explanation:</u>

The boiling point for water at 1 pressure atmosphere of sea level is 212 ° F or 100 ° C. That value isn't a fixed. Water's boiling point is dependent on the ambient pressure, which varies based on elevation. At a lower temperature, water boils as one gains altitude like getting higher on a hill, and boils at a higher temperature if one increases the atmospheric pressure of returning to or below sea level.

It also relies upon the water's purity. Water containing contaminants like salted water boils at a level higher than pure water. This effect is called acceleration of the boiling point and is one of the material's colligative features.

3. The following sound waves have what velocity? (convert cm into m in your calculations.)

mestny [16]

The sound waves with the frequency 20 Hz, 200 Hz, 2,000 Hz, and 20,000 Hz have a velocity of 344 m/s.

<h3>What are sound waves?</h3>

A sound wave is a sample resulting from the motion of strength traveling thru a medium (inclusive of air, water, or every other liquid or stable matter) because it propagates from the supply of the sound. Sound waves are created and convey strain waves, for example, a cellphone.

The frequency can be given as:

Frequency = Velocity/ Wavelength

Velocity = Frequency * Wavelength

The velocity of the following sound waves is given as:

Frequency = 20 Hz

Wavelength = 17.2 m

Velocity = 20 * 17.2 m/s

Velocity = 344 m/s

Frequency = 200 Hz

Wavelength = 1.72 m

Velocity = 200 * 1.72 m

Velocity = 344 m/s

Frequency = 2,000 Hz

Wavelength = 17.2 cm = 0.172 m

Velocity = 2,000 * 0.172 m/s

Velocity = 344 m/s

Frequency = 20,000 Hz

Wavelength = 1.72 cm = 0.0172 m

Velocity = 20,000 * 0.0172 m/s

Velocity = 344 m/s

The Earth has a speed of 108,064.5 km/hr around the sun. The planet Mars has a speed of 86,868 km/hr around the sun.

Leni [432]

Answer:

Graph B

Explanation:

This is because the full question is "The Earth has a speed of 108,064.5 km/hr around the sun. The planet Mars has a speed

of 86,868 km/hr around the sun. Which of the following graphs best represents the

motion of the two planets?" The answer would be B because the more steeper the slope means more speed.

In a car crash, large accelerations of the head can lead to severe injuries or even death. A driver can probably survive an acce

Mandarinka [93]

Answer:

0.22 m

Explanation:

We are told that the driver can survive an acceleration of 50g only if the collision lasts no longer than 30 ms. So,

$t = 30 ms = 0.030 s$

The acceleration is

$a=-50g = -50(9.8)=-490 m/s^2$

where the negative sign is due to the fact that this is a deceleration, since the driver comes to a stop in the collision.

First of all, we can find what the initial velocity of the car should be in this conditions by using the equation:

$v=u+at$

And since the final velocity is zero, v=0, and solving for u,

$u=-at=-490(0.030)=14.7 m/s$

And now we can find the corresponding distance travelled using the equation:

$d=ut+\frac{1}{2}at^2 = (14.7)(0.030)+\frac{1}{2}(-490)(0.030)^2=0.22 m$
