Answer:

15 cm

Explanation:

Dari pertanyaan yang diberikan di atas, diperoleh data sebagai berikut:

Gaya 1 (F₁) = 225 N

Jarak terpisah 1 (d) = 5 cm

Gaya 2 (F₂) = 25 N

Jarak terpisah 2 (d₂) =?

Kita dapat memperoleh persamaan yang berkaitan dengan gaya dan jarak muatan dua titik dengan menggunakan rumus berikut:

F = Kq₁q₂ / d²

Perbanyak silang

Fd² = Kq₁q₂

Menjaga Kq₁q₂ konstan, kita memiliki:

F₁d₁² = F₂d₂²

Dengan rumus di atas maka diperoleh jarak sebagai berikut:

Gaya 1 (F₁) = 225 N

Jarak terpisah 1 (d) = 5 cm

Gaya 2 (F₂) = 25 N

Jarak terpisah 2 (d₂) =?

F₁d₁² = F₂d₂²

225 × 5² = 25 × d₂²

225 × 25 = 25 × d₂²

5625 = 25 × d₂²

Bagilah kedua sisinya dengan 25

d₂² = 5625/25

d₂² = 225

Hitung akar kuadrat dari kedua sisi

d₂ = √225

d₂ = 15 cm

Oleh karena itu, muatan dua titik harus berjarak 15 cm untuk memiliki gaya tarik 25 N

Explain how atoms of elements form molecules, compounds and mixtures.
katrin2010 [14]

An element is composed of millions of atoms and a compound is composed of molecules. When an atom reacts with another atom, a molecule is formed.

For example, if sodium reacts with chloride, it forms sodium chloride (Common salt). Here, sodium and chloride are elements and sodium chloride is a molecule. In this way, millions of atoms of sodium reacts with chloride and forms common salt.

Again, when the common salt is mixed with other compounds such as water, it forms a mixture.

a load of 45 N attached to a spring that is hanging vertically stretches the spring 0.14 m. What is the spring constant?
zhenek [66]
According to Hooke's law, Force = spring constant x displacement of the spring. Spring constant = Force/displacement in spring = 45/0.14 = 321.42 N/m. Hope this helps!

What is the voltage output (in V) of a transformer used for rechargeable flashlight batteries, if its primary has 475 turns, its
VMariaS [17]

Answer:

Output voltage is 1.92 volts.

Explanation:

Given that,

Number of turns in primary coil, N_p=475

Number of turns in secondary coil, N_s=8

Input voltage, V_i=114\ V

We need to find the voltage output of a transformer used for rechargeable flashlight batteries. For a transformer, the number of turns and the voltage ratio is given by :

\dfrac{N_p}{N_s}=\dfrac{V_i}{V_o}\\\\\\V_o=114\cdot\dfrac{8}{475}\\\\V_o=1.92\ V

So, the output voltage is 1.92 volts.

How is power defined? Question 8 options: the quantity of work accomplished the direction of the work the total distance an obje
kifflom [539]

Power is defined by the rate of work done by the object. Statement D represents the correct definition of Power.

<h3>What is Power?</h3>

Power can be defined as the transfer of energy from one place to another place. The rate at which this energy is transferred is called power.

In other words, the rate at which the work is done by an object is called its power. The mathematical representation of power is given as,

P = \dfrac {\Delta W}{\Delta t}

Here, P is the power, \Delta W is the change in energy or work done and  \Delta tchange in time.

The Power can be written in SI units as Watt or J/s.

Hence we can conclude that the power is the rate at which work is accomplished. Statement D is the correct representation of Power.

To know more about power, follow the link given below.
