Which particle remains undeflected when passing
through this electric field?
A) proton
B) electron
C) neutron
D) positron
Answer:
C) neutron
Explanation:
The particles that remains undeflected when passing through this electric field are the neutrons because they do not carry any charges on them.
Neutrons are uncharged particles. Since they do not have any charges on them, they are not affected by the electric field. Both protons and electrons are deflected by the electric field. The charges on these particles causes them to be deflected.The particle which remains undeflected when passing through this electric field is:
C) neutronThe given diagram shows the particle traveling through a field and there are positively, negatively and neutral charged ions.
As a result of this, we can see that the neutron does not get deflected as it is passing through the electric field because they do not have any charge in them and as such cannot be drawn by the electric charge.
Therefore, the correct answer is option C

Which evidence suggests that the materials in the asthenosphere are near their melting point? Choose the correct answer.
The asthenosphere is made of lighter elements.
The temperature of core samples taken from the asthenosphere is near 500 K.
The velocity of seismic waves increases suddenly when they enter the asthenosphere.
The velocity of seismic waves decreases suddenly when they enter the asthenosphere.
Answer: The asthenosphere is made of lighter elements.
Explanation:
The asthenosphere has obtained its name from Greek word called asthenis, which mean weak. The strength of asthenosphere is lower than that of overlying lithosphere. If the temperature of lithosphere raises high enough then asthenosphere will melt. This layer is ductile and deforms very easily.
For visible light, explain how wavelength and energy vary for the different colors. Provide the trends in wavelength for the spectrum of light (purple to blue to green to yellow to orange to red). How is this different for energy?
Answer:
See explanation
Explanation:
If you look closely at the image attached, you will discover that the order of increasing wavelength in the visible spectrum is;
violet < indigo< blue < green < yellow < orange < red
On the order hand, the energy of the photons increases in the order;
Red < orange < yellow < green < blue < indigo < violet
Since energy follows a trend opposite to that of wavelength, we can see that the greater the wavelength of light, the lower the energy of photon corresponding to that particular colour.
A student writes Ba²⁻ as the symbol for a barium ion. Explain what is incorrect about the symbol.
The symbol of barium ion is Ba²⁺. Barium looses two electrons and get positively charge, and it became cation.
What is cation ?Positively charged ions are known as cations. Negatively charged ions are referred to as anions. A charged atom or molecule is an ion. A balanced atom will change into a positively charged cation if one or more of its electrons are lost.
Because they are positively charged and move toward the negative electrode in an electrical field, these ions are referred to as "cations."
The barium ion has a charge of 2+, or a positive charge of two. To become a positively charged ion known as a cation, the barium ion must give up two electrons. Atoms replicate the electron configuration of the closest noble gas by transforming into ions.
Thus, To become a positively charged ion known as a cation, the barium ion must give up two electrons.

Calculate the energy of the lasers in a Blu-ray player, which emit at a wavelength of 4.05x10−7 m.
Answer:
4.907 × 10^-19 J
Explanation:
The energy of the lasers in a Blu-ray player can be calculated by using;
E = hf
Where;
E = Energy of laser (J)
h = Planck's constant (6.626 × 10^-34 J/s)
f = frequency (Hz)
However, the frequency must be known first in order to calculate the energy. The frequency can be calculated using the formula:
f = v/λ
Where:
λ = wavelength (4.05x10−7 m.)
v = speed of light (3 × 10^8m/s)
f = frequency (Hz)
f = 3 × 10^8 ÷ 4.05 x 10^−7
f = 0.7407 × 10^(8 + 7)
f = 0.7407 × 10^15
f = 7.407 × 10^14 Hz
Using E = hf
E = 6.626 × 10^-34 × 7.407 × 10^14
E = 49.07 × 10^(-34 + 14)
E = 49.07 × 10^-20
E = 4.907 × 10^-19 J
Given 1.40 moles of gold (Au), how many atoms do you have?
Answer:
8.428 × 10²³ atomsExplanation:
The number of atoms of Au can be found by using the formula
N = n × Lwhere n is the number of moles
N is the number of entities
L is the Avogadro's constant which is

Answer:
2 atoms
Explanation:
There are 2 atoms in element NaCl. This is because there is 1 atom of Na (sodium) and 1 atom of Cl (chlorine) in each NaCl molecule. Elements by themselves do not have a "number of atoms"- if you're talking about the atomic number, it's the number of protons (or electrons in a neutral atom) of an element.
3.00 Liters of gas are stored at standard temperature and pressure. If the volume of the gas is increased to 4.00 L at a constant temperature what is the new pressure of the gas
The new pressure of the gas : 0.75 atm
Further explanationBoyle's Law
At a constant temperature, the gas volume is inversely proportional to the pressure applied
[tex]\rm p_1V_1=p_2.V_2\\\\\dfrac{p_1}{p_2}=\dfrac{V_2}{V_1}[/tex]
P₁=1 atm ⇒ standart temperature and pressure (STP)
V₁=3 L
V₂=4 L
[tex]\tt P_2=\dfrac{P_1.V_1}{V_2}\\\\P_2=\dfrac{1\times 3}{4}\\\\P_2=0.75~atm[/tex]

Answer:
Solute
Explanation:
A solution is made up of combination of solute and solvent.
The solute is the solid dissolved in a solvent.
Solutions are homogeneous mixtures of solutes and solvents.
In a solution the solutes are evenly distributed in the solvent. The solute is the substance dissolved to make the solution. It is usually present in smaller amount than the solvent. The solvent is the dispersing medium.The diagram shows a certain kind of cell with all of its major parts labeled.

Explanation:
Temperature and kinetic energy have a relationship.
Answer:
[tex]\boxed {\boxed {\sf Temperature=Average \ kinetic \ energy}}[/tex]
Explanation:
Temperature is also known as the average kinetic energy in a substance.
If there is an absence of heat in a substance, the particles move slower and the kinetic energy decreases. The temperature will be lower, because there is less kinetic energy.
If heat is present or applied, the particles move more, so kinetic energy increases. The temperature will be higher, since there is more kinetic energy.
So, the relationship is: temperature is the measure of average kinetic energy.
