A lithium atom has 3 protons, 4 neutrons and 3 electrons. How would the atom change to become a cation? How would the atom change to become an anion?
Answer:
- For the lithium ion to change to become an anion, it will have to gain one or more electrons which can be pulled away from possibly other atoms with a weaker affinity for them.
- For the lithium ion to change to become a cation, it will have to loose one or more electrons which can be drawn by other atoms with a stronger affinity for them.
Explanation:
Generally, an anion has a net negative charge arising from the fact that it has more electrons than protons while a cation has a net positive charge arising from the fact that it has more protons than electrons.
Now, for the lithium ion to change to an anion, it means it has to have more electrons than it's protons. Thus, since it has 3 number each of protons and electrons, it will have to gain one or more electrons which can be pulled away from possibly other atoms with a weaker affinity for them.
Now, for the lithium ion to change to a cation, it means it has to have more protons than it's electrons. Thus, since it has 3 number each of protons and electrons, it will have to loose one or more electrons which can be drawn out by possibly other atoms with a stronger affinity for them.

Why do you think the electron of the hydrogen atom stays close to the proton in the atom’s nucleus?
Answer:
Electrons are retained by the electromagnetic force in the orbit around the nucleus since the nucleus is positively charged in the middle of the atom and absorbs the electrons charged negatively.
Hope this helps!
We have that for the Question "Why do you think the electron of the hydrogen atom stays close to the proton in the atom’s nucleus" it can be said that
Electron of the hydrogen atom stays close to the proton in the atom’s nucleus because hydrogen with a low proton and electron number its repulsion will be low
From the question we are told
Why do you think the electron of the hydrogen atom stays close to the proton in the atom’s nucleus?
Generally
The electrons are father away from the protons in the nucleus as atomic number increasesThis is because of the law of attraction where unlike charges reply
Therefore
For hydrogen with a low proton and electron number its repulsion will be low and Hence electron of the hydrogen atom stays close to the proton in the atom’s nucleus

A 52-kg bike is moving along a smooth road at a constant velocity of 8.4 m/s. What is the net force acting on the bike
Answer:
0 N
Explanation:
Net force = mass × acceleration
∑F = ma
The velocity is constant, so the acceleration is 0. Therefore, the net force is 0.
The net force acting on the bike is 0 N.
What is net force?Net force is the sum of all forces acting on an object. The net force can be calculated using Newton's second law, which states that F = ma, where: F is the net force. m is the mass of the object. a is acceleration.
The velocity is constant, so the acceleration is 0. Therefore, the net force is 0 N.

Explanation:
when the power is positive, you just need to move decimal point to your right , for a number of times which is similar to the value of the power.
Eg. 3.47×10 raised to the power 8.
with this, move the decimal point to the right eight times which will be 347,000,000.
But when the power is negative, move the decimal point to the left for a number times which will be similar to the value of the power.
Eg. 1.96×10 raised to the power negative 3.
move the decimal point leftwards three times which will be 0.00196

Answer:
27m/sExplanation:
Given data
initital velocity u=15m/s
deceleration a=3m/s^2
time t= 4 seconds
final velocity v= ?
Applying the expression
v=u+at------1
substituting our data into the expression we have
v=15+3*4
v=15+12
v=27m/s
The velocity after 4 seconds is 27m/s
A physics book is moved once around the perimeter of a table of dimensions 1.0m by 2.0 m. a. if the book ends up in its initial position, what is its displacement? Type here b. What is the distance traveled?
Answer:
A. 0 m.
B. 6 m.
Explanation:
Displacement is final position to initial position in the shortest length possible, if you end at your initial position then your displacement is basically 0.
Since the book traveled along the perimeter of a table of 1m and 2m then its perimeter is a total of 6m, which is basically how far the book traveled.

Dos masas de 8kg es tan unidas en el extremo de una varilla de aluminio de 400mm de longitud. La varilla está sostenida en su parte media hora en círculos y solo puede soportar una tensión máxima de 800 N ¿cuál es la frecuencia máxima de revolución
Answer:
The maximum frequency of revolution is 3.6 Hz.
Explanation:
Given that,
Mass = 8 kg
Distance = 400 mm
Tension = 800 N
We need to calculate the velocity
Using centripetal force
[tex]F=\dfrac{mv^2}{r}[/tex]
Where, F= tension
m = mass
v= velocity
r = radius of circle
Put the value into the formula
[tex]800=\dfrac{8\times v^2}{200\times10^{-3}}[/tex]
[tex]v^2=\sqrt{\dfrac{800\times200\times10^{-3}}{8}}[/tex]
[tex]v=4.47\ m/s[/tex]
We need to calculate the maximum frequency of revolution
Using formula of frequency
[tex]f=\dfrac{v}{2\pi r}[/tex]
Put the value into the formula
[tex]f=\dfrac{4.47}{2\pi\times200\times10^{-3}}[/tex]
[tex]f=3.6\ Hz[/tex]
Hence, The maximum frequency of revolution is 3.6 Hz.
A block of wood has a mass of 8 g and occupies a volume of 10 cm3. What is its density?
Answer:
0.8 g/cm³
Explanation:
recall that the definition of density is the mass per unit volume of an object.
or mathematically:
density = mass / volume
here we are given that mass = 8 g and volume = 10 cm³
hence,
density = 8 g / 10cm³ = 0.8 g/cm³
The block has a mass of 8 g with a volume of 10 cm³. It density is mass divided by volume that is 0.8 g/cm³.
What is density?
Density of a substance is the measure of its mass per unit volume. Density is dependent on some other factors beside mass and volume such as bond type, temperature and pressure.
The ratio of density of a substance to the density of water is called its specific gravity. If the substance is denser than water it will sink on water otherwise it will float on it.
The mass of the block of wood = 8 g
volume = 10 cm³
Density = mass / volume
= 8 g/ 10 cm³
= 0.8 g/ cm³
Therefore, the density of the wood block is 0.8 g/ cm³.

A person throws a ball horizontally from the top of a building that is 26.1 m above the ground level The ball lands 112 m away from the base of the building Neglect air resistance and useg = 9.81 m/s ^ 2
Answer:
v = 5.21 m/s
Explanation:
Let the initial speed be v.
The top of a building is 26.1 m above the ground level and the ball lands 112 m away from the base of the building.
We need to find the initial velocity of the ball.
Let it was at rest initially. Using the second equation of motion to find time of flight.
[tex]d=ut+\dfrac{1}{2}gt^2\\\\t=\sqrt{\dfrac{2d}{g}} \\\\t=\sqrt{\dfrac{2\times 26.1}{9.81}} \\\\t=2.3\ s[/tex]
No, using the formula of speed.
[tex]v=\dfrac{d}{t}\\\\v=\dfrac{12\ m}{2.3\ s}\\\\v=5.21\ m/s[/tex]
So, the initial velocity of the ball is 5.21 m/s.
