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.
What type of solar eclipse occurs when the moon is in a higher orbit than the sun ?
Answer:
annular solar eclipse
Explanation:
An annular solar eclipse happens when the Moon covers the Sun's center, leaving the Sun's visible outer edges to form a "ring of fire" or annulus around the Moon. It happened because the apparent size of the Moon is smaller than that of the Sun
Answer:
annular solar eclipse
Explanation:
a solar eclipse happens when the moon covers the sun centre
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.
Q. What do you mean by the term radioactivity? Why some elements
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.

A car sets off from the traffic lights. It reaches a speed of 27 m/s in 18 seconds. What is its acceleration?
Answer:
1.6875m/s²
Explanation:
[tex] acceleration = \frac{final \: velocity \: - \: initial \: velocity}{time \: taken} [/tex]
a = unknown.
v (final velocity) = 27m/s
u (initial velocity) = 0m/s (as the car was stationary in the traffic lights).
t (time taken) = 18s
[tex]a = \frac{27 - 0}{16} [/tex]
acceleration = 1.6875m/s²
hope it helps. :)
The total mechanical energy of a basketball is 450 J. If the kinetic energy is 226 J, what must the potential energy be?
Answer:
224 J
Explanation:
The total energy is equal to 450 J and the kinetic energy is equal to 226 J so to find the potential energy you simply subtract the two numbers

The difference between visible light and gamma rays is that
a.
the amplitude of visible light is greater.
c.
they travel through a different medium.
b.
the speed of gamma rays is greater.
d.
the frequency of gamma rays is greater.
Answer:
D. the frequency of gamma rays is greater.
Explanation:
Gamma rays occupy the short-wavelength end of the spectrum; they can have wavelengths smaller than the nucleus of an atom. Visible light wavesare one-thousandths the width of human hair--about a million times longer than gamma rays. Radio waves, at the long-wavelength end of the spectrum, can be many meters long.

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.

I am soooooooooooo desperate.
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
Some people say you can tell if someone has HIV by looking at him or her. True or false? Why?
Answer:False.
Explanation: HIV is a viruse that only shows symptoms after a few weeks. in Fact HIV does not show any physical symptoms. So, no you can not tell if someone has or is been infected by HIV by directly looking at them.

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

Which of the following statements are true about whether atoms tend to gain
or lose electrons?
A. Atoms with one, two, or three valence electrons will lose
electrons.
B. Atoms with five, six, or seven valence electrons will lose
electrons.
C. Atoms with four valence electrons will always gain electrons.
D. Atoms with eight valence electrons usually do not gain or lose
electrons.
Answer:
D. Atoms with eight valence electrons usually do not gain or lose
electrons.
Explanation:
An atom can be defined as the smallest unit comprising of matter that forms all chemical elements. Thus, atoms are basically the building blocks of matters and as such defines the structure of a chemical element.
Generally, these atoms are typically made up of three distinct particles and these are protons, neutrons and electrons.
Valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Valence electrons are used to determine whether an atom or group of elements found in a periodic table can bond with others. Thus, this property is typically used to determine the chemical properties of elements.
Based on the octet rule which states that atoms of chemical elements gain, lose or share electrons so as to have eight (8) electrons in their valence shell. Therefore, atoms of chemical elements bond in order to attain the electronic configuration of a noble gas i.e a full valence shell which comprises of eight (8) electrons.
This ultimately implies that, atoms with eight valence electrons usually do not gain or lose electrons because they're noble gas.
