In the decay shown by this equation what shows that transmits transmutation has taken place?
A) atomic identity stays the same but the total number of protons and neutrons change
B) The element represented by the parent and daughter nuclei are the same
C) atomic identity change it but the total number of protons and neutrons do not
D) The total number of Nucleon changes between the parent and a daughter nuclei
Answer:
The answer is C
I just took the quiz
The statement (C) atomic identity changes but the total number of protons and neutrons do not is correct.
What is transmutation?The addition or deletion of protons to a nucleus is referred to as transmutation. A transmutation occurs when deuterium is converted to helium.
We have a decay equation shown below:
[tex]\rm _{11}^{6}\textrm{C} \rightarrow_{11}^{5}\textrm{B}+_{0}^{+1}\textrm{e}[/tex]
As the one-electron subtraction occurred and atom C becomes atom B so the decay equation is affected by atomic identity, but not by the total number of protons and neutrons.
Thus, the statement (C) atomic identity changes but the total number of protons and neutrons do not is correct.

Why are infrared waves located between microwaves and visible light on the electromagnetic spectrum?
Answer: The infra red waves is located between microwave and visible light based on their WAVELENGTH and FREQUENCY of occurrence.
Explanation:
Electromagnetic waves are those waves that do not require or need a material medium for its propagation, but they are able to travel through a vacuum. They exhibit or show all properties associated or connected with light. They are undeflected in electric and magnetic fields. These electromagnetic waves are arranged in order of their FREQUENCY and WAVELENGTHS which is known as ELECTROMAGNETIC SPECTRUM.
FREQUENCY is defined as the number of cycles which the wave completes in one second and is measured in Hertz(Hz). While WAVELENGTH is defined as the distance between two successive crests or troughs of waves which is measured in meter (m).
The electromagnetic spectrum is made up of the following rays which is arranged from the biggest wavelengths to the smallest:
--> Radiowaves
--> microwave :
--> infrared rays:
--> visible light:
--> ultraviolet rays
--> x-rays and
--> Gamma rays.
According to the arrangement of the spectrum above, the microwave has a higher wavelength and frequency than the infrared rays, while the visible light has a lower wavelength and frequency than the infrared rays.

If there are 0.5 amps of current running through a circuit using a 9-volt battery, what is the resistance of the circuit?
Answer:
18
Explanation:
V = voltage
I = current
R = resistance
V = IR is the equation to find out the Voltage of an item so if we move around the equation so we are trying to resistance it would become R = V/I.
V = IR
R = V/I
R = 9/0.5
R = 18
what is the electric potential at a point in space if a charge of 7.3x 10^-17 coulombs at that point has a potential energy of 6.4
Answer:
V = 0.87 volt
Explanation:
Given that,
Charge, [tex]q=7.3\times 10^{-17}\ C[/tex]
Electric potential energy, [tex]U=6.4\times 10^{-17}\ J[/tex]
We need to find the value of electric potential at a point. The relation is as follows :
[tex]V=\dfrac{U}{q}[/tex]
Where
V is electric potential
So,
[tex]V=\dfrac{6.4\times 10^{-17}}{7.3\times 10^{-17}}\\\\V=0.87\ V[/tex]
So, the value of the electric potential at a point is equal to 0.87 Volts.

are radioactive but some are not?
plz give me answer of each question in three lines
Answer:
breaking apart of atoms of certain elements to release rays of energy or particles.
Atoms are the building blocks of elements. However, some atoms have an excessive number of neutrons or protons in their nuclei. This causes an imbalance in the forces that keep them together, resulting in an excessive amount of internal energy. These atoms are referred to as radioactive or unstable.

PLEASE HELP (NO LINKS!)As the pendulum swings from position A to position B, what is the
relationship of kinetic energy to potential energy (neglect friction)? (5
points)
The kinetic energy increase is equal to the potential energy decrease.
The potential energy increase is equal to the kinetic energy decrease.
The kinetic energy and potential energy remain the same.
The kinetic energy increase is more than the potential energy decrease.
Answer:
the kinetic energy decrease is equal to potential energy increase
If the potential energy of pendulum increases then the kinetic energy decreases and if the kinetic energy increases then the potential energy decreases.
what is conservation of energy?According to the work power theorem the total energy of any object will remain constant like the sum of the kinetic and the potential energy of the object will remain constant.
The potential energy of any object is due to its position with respect to the ground. If the object is at a height of H then it will have a potential energy because some energy is given to that object against the gravity to move it to the height H.
The kinetic energy is the energy due to the velocity of the object and is given as the product of half mass to the velocity square.
Now we will express it in the form of the formula for better understanding .
[tex]\rm Total\ energy= KE+PE[/tex]
Now in the pendulum the motion is back and forth with respect to its mean position. So the total energy in the pendulum is the sum of the kinetic energy and the potential energy.
Now if the pendulum attains the maximum displacement from its mean position then it will have maximum potential energy and zero kinetic energy at this point.
Now if the pendulum is at the mean position now it will have maximum kinetic energy and zero potential energy at this point.At this point the potential energy totally converted to the kinetic energy.
Now at the maximum displacement the kinetic energy totally converts into the potential energy of the pendulum.
Thus If the potential energy of pendulum increases then the kinetic energy decreases and if the kinetic energy increases then the potential energy decreases.

1. Se tienen 10 moles de gas nitrógeno molecular: N2 en un recipiente a 400 K. Manteniendo la temperatura a 400 K y las 10 moles en el recipiente se disminuye la presión desde 10 atm a 1 atm para obtener un volumen final del gas de 20 litros. El volumen inicial del gas a. 0,5 litros b. 2 litros c. 100 litros d. 200 litros
Answer:
B. 2 litros.
Explanation:
De acuerdo con el enunciado, el gas experimenta un proceso isotérmico y se conserva su masa. Asumiendo que el gas se comporta idealmente, tenemos la siguiente relación entre los estados final e inicial:
[tex]P_{1}\cdot V_{1} = P_{2}\cdot V_{2}[/tex] (1)
Donde:
[tex]P_{1}, P_{2}[/tex] - Presiones inicial y final, medidos en atmósferas.
[tex]V_{1}, V_{2}[/tex] - Volúmenes inicial y final, medidos en litros.
Si sabemos que [tex]P_{1} = 10\,atm[/tex], [tex]P_{2} = 1\,atm[/tex] y [tex]V_{2} = 20\,L[/tex], entonces el volumen inicial del gas es:
[tex]V_{1} = \frac{P_{2}\cdot V_{2}}{P_{1}}[/tex]
[tex]V_{1} = 2\,L[/tex]
Por lo tanto, la respuesta correcta es B.

Answer:
the correct one is B ₊₁e
Explanation:
In the radioactive emission process there are three fundamental types, enision of alpha particles, emission of beta rays and emission of high energy photons.
In beta particle emission processes, a neutron decomposes, emitting an electron and an antineutrino, so the mass number of the nucleus does not change, but the atomic number increases by one unit.
Another possibility is the emission of a positron (positive charge) plus a neutrino, in this case the atomic mass remains constant and the atomic number decreases by one unit.
The second beta emission process if it describes the situation presented, when reviewing the answers the correct one is B
