The correct toption is (C) 13
The neutral atom of aluminum possess 13 protons.
Aluminum, denoted by the letter Al, is a group 3 element on the periodic chart. Total weight is 27 kilos. Since the number of electrons and protons in a neutral atom are equal, an aluminum atom that is neutral or uncharged has 13 electrons, 13 protons, and 14 neutrons. Keep in mind that the product of protons and electrons determines mass.The solution to this is that a 3+ charge on an aluminum ion means that an aluminum atom has lost three electrons, or 13 electrons - 3 electrons = 10. An aluminum atom will consequently have 10 electrons because it has a +3 charge. The fact that an aluminum atom possesses 13 protons when it is in a neutral state is unaffected by this.Learn more about the quantum mechanics with the help of the given link:

Autotransformers are especially practical if the difference between the primary and secondary voltages is _____.
Autotransformers are especially practical if the difference between the primary and secondary voltages is realtively small.
What is Autotransformer?An autotransformer is a type of electrical transformer that has just one winding. The word "auto" refers to a single coil that runs autonomously, not to a system that runs without human intervention. The primary winding and secondary winding sides of an autotransformer are distinct portions of the same winding. While there is no metallic conducting channel between the primary and secondary windings of a normal transformer, they are separate. The autotransformer winding has at least three taps that are utilized to connect electrical appliances. In terms of size, weight, and cost, autotransformers usually outperform conventional dual-winding transformers, but they also have the disadvantage of lacking electrical isolation between the primary and secondary circuits. Autotransformers also have advantages in terms of reduced leakage reactance, fewer losses, lower excitation current, and higher VA rating for a given size and mass.Learn more about the Autotransformer with the help of the given link:

Object a is moving at speed v in a circle of radius r. object b is moving at speed 2v in a circle of radius r/2. what is the ratio of the period of object a to the period of object b?
The correct answer for the ratio of the period of object a to the period of object b 4.
we know time for one revolution. around which is the period for one revolution it has to travel distance equal to perimeter.
So, speed of object in circular motion
v = perimeter /t
time period = 2πr/v
for object A ,Ta = 2 π R/ v
for abject B, Tb = (2π R/2 )/2v
now Ta / Tb = ((2πR)/v)/((2π(R/2))/(2V)) = 1/(1/4) = 4
Circular motion is defined in physics as the movement of an object around the circumference of a circle or the rotation of an object along a circular path. It can be uniform, with a constant angular rate of rotation and speed, or non-uniform, with a variable rate of rotation.When the magnitude of an object's velocity in uniform circular motion is v, the velocity is equal to the circumference C of the circle divided by the period.

A star that has exhausted its supply of hydrogen is considered _____. group of answer choices
a. depleted
b. eroded
c. mature
d. dead
Answer:
A mature star is a star that has exhausted its supply of hydrogen
Explanation:
For the most part, a star is powered by nuclear fusion. The energy is first produced by the fusion of hydrogen atoms in the core of a main-sequence star. Later, when the helium predominates in the core, stars like the Sun begin to fuse hydrogen along a spherical shell around the core. This allows the star to steadily increase in size, passing through the subgiant stage and eventually reaching the red giant stage.
When they reach this stage, the hydrogen in them nearly completely depletes, and they get brighter and hotter, eventually becoming low-mass white dwarfs.
When a star's supply of hydrogen in its core runs out, leaving only helium, the outward force provided by fusion begins to diminish, and the star can no longer maintain equilibrium. When the force of gravity exceeds the force of internal pressure, the star begins to disintegrate. The outcome of this collapse is determined by the mass of the star.

The velocity vector is v(t) = 6t i + 3t j + k, and the position vector is r(t) = [tex]\rm 3t^2 i + (3/2)t^2 j + kt + i.[/tex]
We have to integrate the specified acceleration vector to obtain the velocity vector of the particle before integrating the velocity vector to obtain the position vector of the particle.
So, the acceleration vector: a(t) = 6i + 3j
We will the find the velocity vector,
To find the velocity vector, we integrate the acceleration vector with respect to time 't':
∫a(t) dt = ∫(6i + 3j) dt
when we integrate with respect to time 't' that gives us:
v(t) = 6t i + 3t j + C
where 'C' is the constant of integration.
Using the initial velocity condition to find 'C':
Given initial velocity: v(0) = k
Substitute t = 0 into the velocity vector equation:
v(0) = 6(0) i + 3(0) j + C
k = C
So, C = k
We put the value of 'C' back into the velocity vector equation:
v(t) = 6t i + 3t j + k
Calculate the position vector r(t):
To find the position vector, we integrate the velocity vector with respect to time 't':
∫v(t) dt = ∫(6t i + 3t j + k) dt
Integrating with respect to time 't' gives us:
r(t) = [tex]\rm 3t^2 i + (3/2)t^2 j + kt + D[/tex]
where 'D' is the constant of integration.
We use the initial position condition to find 'D':
Given initial position: r(0) = i
Substitute t = 0 into the position vector equation:
r(0) = [tex]\rm 3(0)^2 i + (3/2)(0)^2 j[/tex]+ k(0) + D
i = D
So, D = i
when we put the value of 'D' back into the position vector equation:
r(t) = [tex]\rm 3t^2 i + (3/2)t^2 j + kt + i[/tex]
Therefore, the velocity vector is v(t) = 6t i + 3t j + k, and the position vector is r(t) = [tex]\rm 3t^2 i + (3/2)t^2 j + kt + i.[/tex]

Calculation:
According to the Bernoulli equation:
P/? + v^2/2 + gz = constant
However, the atmospheric pressure and density are essentially the same at the peak and bottom of the falls. Therefore,
v^2/2 + gz = constant , so:
v_bottom^2/ 2 = v_top^2/2 + gz, or:
v_bottom = sqrt(v_top^2 + 2gz) = sqrt(v_top^2 + 2g*170)

Photons move at the speed of light and have no charge or rest mass. Charged particles produce photons, though they can also be produced by other processes, such as radioactive decay.
It's common to refer to photons as energy packets. This analogy is excellent because a photon has uncondensable energy. An alternating electric field is how this energy is kept in reserve. The universe's size, which is the longest theoretical wavelength of light, and the Planck length, which some theories claim to be the smallest, have never been measured.

The postal service had a special deal. You could ship up to 2 kg for five dollars for a
limited time. For Amy's friend's birthday, Amy wanted to ship her sweets and candy,
and she wanted to get the best bang for her buck. She first made her cookies. They
had a mass of 400 grams. How many kilogram (s) of sweets and candy could Amy
still ship if only the cookies were in the box for the five dollar special?
weight of sweets and candy is 1.6kg
It is given that a total weight of 2 kg is allowed by the postal service
The weight of cookies is given to be 400gm
we know that 1kg =1000gm
400gm= 400/1000 gm =0.4kg
Therefore weight of sweets and candy that Amy can send=
total weight- weight of cookies
=2kg - 0.4kg
=1.6kg
Therefore, weight of sweets and candy is 1.6kg
