During the 1800s in England, relations police, which became composed of male volunteers, became organised to observe the protection and protection of their relatives.
What is protection?Protection is any measure taken to guard a thing against damage.
During the 1800s in England, relations police, which became composed of male volunteers, became organised to observe the protection and protection in their relatives.
As Britain's populace step by step expanded, so did the number of crimes that had been committed. This intended that regulation and order additionally needed to improve.
The New York City Police Department (NYPD) originates withinside the Government of New York City and tries to manipulate growing crime in early to mid-nineteenth century New York City.
This expanded crime became because of an expanding populace, brought about usually through negative Irish immigrants starting withinside the 1820s.
Whereas, as societies have become greater heterogeneous and complex, the function of the police is turning greater demanding. To fulfil this function, law enforcement officials want numerous broadly acknowledged competencies and private qualities, however much less is thought approximately how they're valued through police recruits.
Thus, we've tested the perspectives of police recruits in six European nations on 3 skills or traits of regarded significance for police work: knowledge, leadership, and the cap potential to shape precise family members with residents.
We have additionally explored versions in perspectives of recruits in distinct businesses and modifications of their perspectives for the duration of their schooling. For those purposes, we used survey facts accumulated withinside the RECPOL project.
Since the facts had been accumulated from distinct populations and at distinct times, the evaluation is primarily based totally on dimension invariance methodology, and one of the objectives became to spotlight the significance of rigorous appraisal of the pleasant and comparison of comparable survey facts the use of such methods.
The consequences display each variation and similarities in perspectives of recruits withinside the surveyed nations and modifications for the duration of schooling.
Police lifestyle seems to be an extensive factor, as greater objects withinside the carried out device can be validly utilized in comparisons of recruits in businesses with comparable policy traditions.
The consequences additionally confirmed exciting contrasts, e.g. new recruits in Sweden rated precise family members with residents greater surprisingly than recruits in businesses with a greater army history, however, this sample was modified for the duration of schooling, probably because of the effects of the recruitment process, schooling and lifestyle in the businesses.

Imagine if Rutherford conducted his scattering experiment, and his prediction about the movement of alpha particles held true Which of the other models or scientific
observations would have also been confirmed?
The Bohr model would have been confirmed because it shows electrons spinning around a nucleus
The plum pudding model would have to be true as well because it shows that electrons are scattered within an atom,
The Bohr model would have been confirmed because it shows electrons occupying random positions inside the electron cloud.
The plum pudding model would have to be true as well because it shows that all positive charge is concentrated at the center of the atom
Answer:
The plum pudding model would have to be true as well because it shows that electrons are scattered within an atom.
Explanation:
I took the test and got it right :)
The plum pudding model would have to be true as well because it shows that electrons are scattered within an atom
The model of the atom proposed by Rutherford is called the nuclear model of the atom called the nuclear model of the atom. It was proposed after his famous experiment using a thin gold foil.
His previous prediction was that the alpha particles will bend or deflect around the positively charged areas of the gold atom. If this prediction came true, the plum pudding model would have to be true as well because it shows that electrons are scattered within an atom.

An aqueous solution of a vanadium chloride salt is electrolyzed by a current of 3.00 A passing through the solution for 60.0 min. If 5.70 g of vanadium is produced at the cathode during this time, what is the likely formula unit for the vanadium salt
From the information in the question, the formula unit of the salt is given as VCl.
The quantity of charge produced is obtained from;
Q = It
I = current (3 A), t = time (3600 s)
Q = 3 A × 3600 s
Q = 10800 C
Now we need to find the number of electrons transferred as follows;
51 g of Vanadium is deposited by 96500n C
5.70 g is deposited by 10800 C
5.70 × 96500n = 51 × 10800
n = 51 × 10800/5.70 × 96500
n = 1
The formula of the salt is VCl.

Why is the speed of sound more in solids than in gases ?......
Explanation:
Sound travels fastest through solids. This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it. In fact, sound waves travel over 17 times faster through steel than through air.
Sound waves move faster in solids where the particles are compacted than in gases where the molecules are far apart from each other.
We know that the particles in a solid are held together by strong intermolecular forces while the particles in a gas are not held together by intermolecular forces.Since sound waves are transmitted as vibrations, sound waves move faster in solids where the particles are compacted than in gases where the molecules are far apart from each other.Hence, sound moves faster in a solid than in gases.

How many moles of NH3 can be produced from 5.50 moles of nitrogen in the following reaction: N2+3H2=2NH3
Answer:
Explanation:
Let the molar balance numbers be your guide.
N2 has a one in front of it.
2 NH3 has a two in front of it.
Nitrogen has 5.50 moles given.
1 / 5.50 = 2 / x Cross multiply
1 x = 2 * 5.50
x = 11.0
So if you use 5.5 moles of nitrogen, you get 11 moles of NH3

Find the volume of 0.160 M sulfuric acid necessary to react completely with 75.0 g sodium hydroxide.
The volume of 0.160 M sulfuric acid necessary to react completely with 75.0 g sodium hydroxide is 0.15L
The reaction of sulphuric acid and sodium hydroxide is expressed as:
[tex]2NaOH + H_2SO_4 ==> Na_2SO_4 + 2H_2O[/tex]
Determine the moles of NaOH present
Molar mass of NaOH = 23 + 16 + 1 = 40g/mole
Given that mass of NaOH is 75.0g
Mole of NaOH = 75/40 = 1.875moles
Determine the number of moles [tex]H_2SO_4[/tex] needed to react with 1.875 moles NaOH
Moles of [tex]H_2SO_4[/tex] = [tex]\frac{1.875}{2} = 0.9375moles of H_2SO_4[/tex]
Recall that volume = Molar mass * number of moles
Volume of [tex]H_2SO_4[/tex] = 0.160 * 0.9375
Volume of [tex]H_2SO_4[/tex] = 0.15L
