Answer:

<h2>Krypton is a colorless, odorless gas. It has a boiling</h2><h2> point of -152.9°C (-243.2°F) and a density of 3.64 </h2><h2>grams per liter. </h2><h2>That makes krypton about 2.8 times as dense as air.</h2>

<h2>SECONDLY, Krypton is one of the rarest gases on Earth, composing only 1 part per million of the atmosphere by volume. This noble gas is colorless and odorless. It has a full outer shell of electrons, rendering it largely inert to reactions with other elements.</h2>

A 77 ton monolith is transported on a causeway that is 3500 ft long and has a slope of about 3.6 degrees. How much force paralle

const2013 [10]

Answer:

4.8 ton

Explanation:

We are given that

Mass,m=77 ton

Displacement,s=3500 ft

$\theta=3.6^{\circ}$

We have to find the force parallel to the incline would be required to hold the monolith on this causeway.

The force parallel to the incline would be required to hold the monolith on this causeway= $Fsin\theta$

Using the formula

The force parallel to the incline would be required to hold the monolith on this causeway= $77sin3.6=4.8 Ton$

1. A note has a wavelength of 0.77955 m. If the speed of sound is 343.00 m/s, what pitch is this note? 2. A note has a wavelengt

AVprozaik [17]

Answer:

1.) 440 Hz

2.) 659.3 Hz

Explanation:

1.) Given parameters are:

wavelength = 0.77955 m.

speed of sound = 343.00 m/s

Frequency = speed/ wavelength

Substitute speed and wavelength into the formula

Frequency = 343/ 0.77955

Frequency = 439.99

Frequency = 440 Hz approximately

2.) The parameters given are:

wavelength = 0.52028 m.

speed of sound = 343.00 m/s

Using the same formula

Frequency = speed/wavelength

Substitute all the parameters into the formula

Frequency = 343 / 0.52028

Frequency = 659.3 Hz approximately

The pitch of a note depends on the frequency of the sound waves.

The pitch of a sound increases as the frequency of the sound waves increases.
