Why are scientists now more excited about sound levitation than they had been previously?
SELECT AN ANSWER
Sound levitation was previously only a theory and has only now been done experimentally.
By using sound levitation at the right frequency, scientists can break objects like glass.
The cost of sound levitation has decreased dramatically over the past decade.
Research has shown scientists can control the movement of liquids with sound without touching the liquid
Answer:
Acoustic tractor beams use the power of sound to hold particles in mid-air, and unlike magnetic levitation, they can grab most solids or liquids even small insects. For the first time engineers have shown it is possible to stably trap objects larger than the wavelength of sound in an acoustic tractor beam. This discovery could enable the manipulation of drug capsules or micro-surgical implements within the body. The discovery could even lead to levitating humans.

Which of these particles is the smallest?
A.a proton
B.a nucleus
C.an electron
D.an atom
Answer:
an atom. It is the smallest thing known to man kind
Explanation:
Answer:
C
Explanation:
so basically, we can eliminate some answer choices right away.
an atom (answer choice D) is made up of all the other answer choices, so that is the largest (not the answer).
a nucleus (answer choice B) is made up of protons (answer choice A) and neutrons which means it is not the smallest either (not the answer).
now, we are left with a proton and an electron. electrons are much smaller than protons, so they are usually not included in an element's atomic mass. therefore, an electron is the smallest out of these answer choices.

Think about atoms, molecules, elements, and compounds. How can you relate it to your own body? To the world around you, right now? Please explain in four sentences.
Answer:
Everything we see comes from the transferring of electrons, or redox reactions. Fire, the screen you are staring at, and many other chemical reactions that happen everyday, we don't even care to notice anymore. Everything in our bodies is made up of compounds, from simple things such as H2O, and to the food we eat, loaded with sugar, C12H22O11.

The atomic mass of Gallium is 69.72 AMU. The masses of the naturally occurring isotopes are 68.9257 AMU and 70.908 AMU for Ga-69 and Ga-71. Find the percent (%) abundance for each.
Answer:
40.7% abundance of Ga-71
59.93% abundance of Ga-69
Explanation:
Given data:
Average atomic mass of Ga = 69.72 amu
Atomic mass of Ga-69 = 68.9257 amu
Atomic mass of Ga-71 = 70.908 amu
Percent abundance of each isotope = ?
Solution;
we know there are two naturally occurring isotopes of Ga.
First of all we will set the fraction for both isotopes
X for the isotopes having mass 68.9257
1-x for isotopes having mass 70.908
we will use the following equation,
68.9257x + 70.908 (1-x) = 69.72
68.9257x +70.908 - 70.908x = 69.72
68.9257x - 70.908x = 69.72 - 70.908
-1.9823x = - 1.188
x= 1.188/1.9823
x= 0.5993
0.5993 × 100 = 59.93 %
59.93 % is abundance of Ga-69 because we solve the fraction x.
now we will calculate the abundance of Ga-71.
(1-x)
1 - 0.5993 = 0.4007
0.4007× 100= 40.7 %
40.7 % for Ga-71.

what is the volume when the density is 7.83g/ml and 19.6 grams?
A 57.9 gram mass has a volume of 3 cm 3. What is the density of the mass?
Answer:
The answer is 19.3 g/cm³Explanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume}\\[/tex]
From the question
mass = 57.9 g
volume = 3 cm³
We have
[tex]density = \frac{57.9}{3} \\ [/tex]
We have the final answer as
19.3 g/cm³Hope this helps you

What is the primary type of heat transfer?: A cool breeze blows off the water.
Answer:
Explanation:
Heat transfer occurs by three main mechanisms: conduction, where rigorously vibrating molecules transfer their energy to other molecules with lower energy; convection, in which the bulk movement of a fluid causes currents and eddies that promote mixing and the distribution of thermal energy

You just need one to reach full energy. (A)
Only one electrons does chlorine need to obtain a full outer energy level of electrons. Thus, option A is correct.
What is an electron?An electron is defined as a subatomic particle which is charged negatively either bounded to an atom or not it means free. The nucleus of an atom is made up of electron, proton and neutron. The electron is a basic particle and electron is not made of anything.
The nature of electron is free it means they are present freely in nature and consist of an atom.The main function of electron is that they play the role of negatively- charged component of an atom.
The electrons are primary source of current conducting and electrons number as well as atomic number of an element is always same or equal. There is no size of electron but the mass of electron is 9×10^-31.

what frequency does television channel 7 broadcast at?
Answer:
Channel 7's frequency is 117.5 MHz
Answer:
174 MHz - 180 MHz w/ center frequency of 177 MHz
Explanation:
216 - 174 = 42
42/7 = 6
6 + 174 = 180 - 7 - 177 MHz
180 + 6 = 186 - 8 - 183 MHz
186 + 6 = 192 - 9 - 189 MHz
192 + 6 = 198 - 10 - 195 MHz
198 + 6 = 204 - 11 - 201 MHz
204 + 6 = 210 - 12 - 207 MHz
210 + 6 = 216 - 13 - 213 MHz
