The moon setting on your way to work about two hours after sunrise means it is in the gibbous phase.

<h3>What is Gibbous phase?</h3>

This phase of the moon involves its side facing the Earth appearing more than half-lit by the Sun, but is less than fully lit.

This phase occurs few hours after sunrise usually in the early morning which is why it is the most appropriate choice.

Which statement best describes what is happening at

12345 [234]

Answer:

Water is absorbing heat.

Explanation:

Water is able to absorb heat

- without increasing much in temperature - better than many substances.

This is because for water to increase in temperature, water molecules must be made to move faster within the water; this requires breaking hydrogen bonds, and the breaking of hydrogen bonds absorbs heat.

If you could use an elevator or the stairs to lift a box to the tenth floor,which has greater power?why?

Nostrana [21]

Stairs don't HAVE any power. When you use the stairs, YOU have to provide all the power. I would use the elevator, because the machinery that runs it produces the power and I only have to stand there.

Small blocks A and B are held at rest on a smooth plane inclined at 30° to the horizontal. Each is held in equilibrium by a forc

Olin [163]

<h3>Answer :</h3>

First of all, See the attachment for better understanding $.$

_________________________________

❂ Weight of block A :

➝ mg sin30° = 18

➝ W (1/2) = 18

➝ W = 18×2

➝ W = 36N 

❂ Weight of block B :

➝ N sin30° = 18

➝ (Mg cos30°) sin30° = 18

➝ W' (√3/2)(1/2) = 18

➝ W' (√3/4) = 18

➝ W' = 72/√3

➝ W' = 41.61N

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
