Answer:

Perubahan energi potensial pegas adalah 17.1675 J

Explanation:

Untuk menyelesaikan pertanyaan, kami mencatat bahwa energi potensial elastis diberikan sebagai;

Energi potensial elastis= E_p=\frac{1}{2} \times k \times x^{2}

Dimana:

k = Konstanta pegas

x = perpanjangan musim semi = 7 cm = 0.07 m  

Paksa di musim semi =   -kx

Di mana, pegas adalah satu-satunya objek yang berkontribusi pada gaya yang kita miliki

Memaksa= m×g = 5 × 9.81 = 49.05 N

Karena itu, k = 49.05/0.07 = 700.714 N/m

Oleh karena itu, perubahan energi potensial elastis adalah

E_{p1}=\frac{1}{2} \times k \times x_1^{2}\\E_{p2}=\frac{1}{2} \times k \times x_2^{2}\\\Delta E_p = E_{p2} -E_{p1} = \frac{1}{2} \times k \times x_2^{2} - \frac{1}{2} \times k \times x_1^{2} = \frac{1}{2} \times k \times (x_2^{2} - x_1^{2})

Kami memiliki, x₁ = 0 m karena pegas diasumsikan awalnya tidak diregangkan

Karena itu,

\Delta E_{p}=\frac{1}{2} \times k \times x_2^{2}

\Delta E_{p}=\frac{1}{2} \times 700.714 \times 0.07^{2} = 17.1675 J and

Perubahan energi potensial pegas = 17.1675 J

Answer:

It is elastic potential energy

Explanation:

Elastic potential energy is stored energy that results from applying a force to deform an elastic object. The energy is stored until the force is removed and the elastic object returns to its original shape, doing work in the process. Deformation may involve compressing, stretching, or twisting the object. Many objects are specifically designed to store elastic potential energy, for example:

The spring of a winding watch.

the hydrometer with the density of liquid to be 800 kg metre per square is the volume of the submerged part of the hydrometer is
julia-pushkina [17]

Answer:

Mass = 0.04 Kg

Explanation:

Given the following data;

Density = 800 kg/m³

Volume = 5 * 10^{-5} m³

To find the mass of the object;

Density can be defined as mass all over the volume of an object.

Simply stated, density is mass per unit volume of an object.

Mathematically, density is given by the formula;

Density = \frac {mass}{volume}

Making mass the subject of formula, we have;

Mass = density * volume

Substituting the values into the formula, we have;

Mass = 800 * 5 * 10^{-5}

Mass = 0.04 Kg
