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.

Pepsi [2]
Applicable linear expansion equation:
ΔL = αΔTL
In which
ΔL = change in length, α = Linear expansion coefficient of steel, ΔT = change in temperature, L = original length

Therefore,
ΔL = 12*10^-6*(18.5-(-3))*1410 = 0.36378 m

The gravitational potential energy of the ball changes as it bounces. Where is the ball located when its gravitational potential
Cloud [144]

When the planet is closest to the Sun, speed v and kinetic energy are the highest, and gravitational potential energy is the lowest. When the planet moves farther away, the speed and kinetic energy decrease, and the gravitational potential energy increases.

Which of the following will cause an induced current in a coil of wire? A. A wire carrying a constant current near the coil B. A
Vika [28.1K]

Answer:

B. A magnet being moved into or out of the coil

Explanation:

Faraday law of electromagnetic induction states that when there is change in flux , an emf is produced . Among the given instances , only in case of B , flux is changing . So current will be induced in the coil . We shall see how it takes place .

A wire carrying constant current will produce magnetic flux in nearby coil but there is no change in flux because current as well as position of wire with respect to coil are  not changing  .

Passing of magnetic field through a stationary coil produces flux in the coil but here too there is no change in flux so no current will be induced .

A magnet positioned near a coil creates magnetic flux in the coil but the magnitude of flux remains constant so no change in flux and no creation of induced current .
