Explanation:
Beta particles have a mass which is half of one thousandth of the mass of a proton and carry either a single negative (electron) or positive (positron) charge. As they have a small mass and can be released with high energy, they can reach relativistic speeds (close to the speed of light)

Explanation:
A magnesium atom that loses 2 electrons becomes a
A) Positive ion with a smaller radius
B) Positive ion with a larger radius
C) Negative ion with a larger radius
D) Negative ion with a smaller radius
Answers
Answer:
A
Explanation:
because the atomic radius reduced by loosing one energy level leading to a positive ion in the resulting ion
The study of chemicals and their bond is called chemistry.
The correct answer is A.
The metals have the property to lose electrons to become stable compounds.
In magnesium, the total number of electrons is 12. In a valance shell, they have 2 electrons.
when they lose or donate the two electrons to the other. The outer shell will be empty and the force of the nucleus remains in the inner shell.
The loss of electrons leads to a decrease in the size of an atom and form positive ions.
Hence, the correct answer is A that is a Positive ion with a smaller radius.

A. Dinitrogen sulfide
B. Dinitride pentasulfur
C. Dinitrogen pentasulfide
D. Nitrogen sulfide
Answers
Answer:
dinitrogen pentasulfide
Explanation:
The correct name for the compound N₂S₅ is Dinitrogen pentasulfide and the correct option is option C.
Naming of compounds refers to the systematic process of assigning names to chemical compounds based on their composition and structure. It involves following certain rules and conventions to generate appropriate names that accurately represent the chemical formula and characteristics of the compound.
In inorganic chemistry, naming compounds often involves identifying the elements present and specifying their respective oxidation states or charges. Various naming conventions, such as the Stock system and the common system, are used depending on the type of compound and the specific elements involved.
Thus, the ideal selection is option C.

Answer:
a current flows through the loop of wire.
Explanation: my answers were worded diffrently
A loop of wire turns between two permanent magnets in a generator and the effect of this motion is conversion of Mechanical energy transforms into electrical energy.
What is generator?Generator is a device which is used to convert mechanical energy to electrical energy.
In generator between the two poles of magnet a loop of wire rotate by the mechanical force which produces magnetic field which in turn convert into the electric field.

Use your knowledge of modern atomic theory and bonding to explain each of the following experimental observations. (Your explanations should be specific.) Refer to both substances when comparing. Within a family such as the alkaline earth metals, the ionic radius increases as the atomic number increases. The radius of the bromine atom is smaller than the radius of the bromide ion, Br-1. The first ionization energy of aluminum is lower than the first ionization energy of magnesium.
Answers
Answer:
(1) In the modern day periodic table the atomic size is increasing when we move down the group and it decreases when we move along the period from left to right. that's why Within a family such as the alkaline earth metals, the ionic radius increases as the atomic number increases. Alkaline earth metals have loosely held electrons which results in its increased size.
(2) The radius of the bromine atom is smaller than the radius of the bromide ion, Br-1 this happens because bromine is a non metal, and it also has a high electronegativity among other group elements as halogen group has high electronegativity. when the bromine acquires one extra electron and forms [tex]Br^-[/tex] ion, the configuration of bromine earlier was [tex]1s^22s^22p^63s^23p^64s^23d104p^5[/tex] but on addition of the electron the p shell will now have 6 electrons resulting in [tex]1s^22s^22p^63s^23p^64s^23d104p^6[/tex]the newly added electron repels the former neutral orientation and as a result of repulsion the size increases.
(3) The first ionization energy of Aluminum is lower than that of the first ionization energy of magnesium because magnesium has fully filled [tex]3s^2[/tex] orbital whereas Aluminum has one electron in the 3p orbitals, fully filled 3s orbitals has strongly held by the nucleus in case of Mg whereas 3p orbitals is shielded from the nucleus therefore it becomes easy to take out 3p electron that 3s electron.
An object is located 360 millimeters from a converging lens. The image formed is 150 millimeters high, at a distance of 90 millimeters from the lens. What’s the height of the object?
Answers
The height of the object : 600 mm
Further explanationGiven
d object=360 mm(object distance)
d image=90 mm(image distance)
Required
h object
Solution
focal length = f :
[tex]\tt \dfrac{1}{f}=\dfrac{1}{d_o}+\dfrac{1}{d_i}\\\\\dfrac{1}{f}=\dfrac{1}{360}+\dfrac{1}{90}\rightarrow f=72~mm[/tex]
The magnification :
[tex]\tt M=\dfrac{d_i}{d_o}=\dfrac{90}{360}=0.25[/tex]
[tex]\tt M=\dfrac{h_i}{h_o}\\\\0.25=\dfrac{150}{h_o}\rightarrow h_o=600~mm[/tex]

If a 50kg car is pulling a 30kg car, how much force would be required to accelerate the cars at 2m/s/s?
Answers
Answer:
160N
Explanation:
The force required to accelerate the two cars can be calculated thus:
F = m × a
Where;
F = force (Newton)
m = mass (kg)
a = acceleration (m/s²)
However, according to the question, a 50kg car is pulling a 30kg car, which means that the mass of the two cars is 50kg + 30kg = 80kg.
a = 2m/s²
F = ma
F = 80 × 2
F = 160N
