When the spring is replaced with a spring with double of initial spring constant k2 = 2k₁, the new period, T2, is [tex]\sqrt{\frac{1}{2} } \ T_1[/tex].

The period of the oscillation of the mass or cart on the spring is given by the following formula;

[tex]T = 2\pi \sqrt{\frac{m}{k} } \\\\[/tex]

at a costant mass;

[tex]T_1\sqrt{k_1} = T_2\sqrt{k_2} \\\\T_2 = \frac{T_1\sqrt{k_1} }{\sqrt{k_2} }[/tex]

when spring constant is doubled, k2 = 2k1. the new period, T2 is determined as follows;

[tex]T_2 = \frac{T_1\sqrt{k_1} }{\sqrt{2k_1} } \\\\T_2 = \frac{T_1\sqrt{k_1} }{\sqrt{2} \times \sqrt{k_1} } \\\\T_2 = \frac{T_1}{\sqrt{2} }\\\\T_2 = \sqrt{\frac{1}{2} } \ T_1[/tex]

Thus, when the spring is replaced with a spring with double of initial spring constant k2 = 2k₁, the new period, T2, is [tex]\sqrt{\frac{1}{2} } \ T_1[/tex].

Positioning your Slinky along any direction different from its initial position will affect your reading, because there will be change in the magnetic field.

If the Slinky is made of an iron alloy, it can be magnetized by itself. Moving the Slinky around can cause a change in the magnetic field, even if no current is flowing.

When there is a change in the magnetic field, the reading changes.

At any point, you change the orientation of the Slinky, you will need to zero the reading or adjust the Slinky back to its initial position, even if the sensor does not move.

Thus, Positioning your Slinky along any direction that is different to its initial position will affect your reading because there will be change in the magnetic field.

Answer:

It takes total 248 years for Pluto to orbit the sun.

Pluto will take 253 year to orbit the sun.

Earth's average distance to the Sun is about 93 million miles (150 million kilometers) from the Sun.

Pluto has a semi-major axis distance a=40 then T2=403, which gives T=253 years.

Therefore, Pluto will take 253 year to orbit the sun.

Answer:

Explanation:

Force of Tension = (m)(g)

120 = (m)(9.8)

m = volume(density)

120 = (4/3)πr³(0.308)(9.8)

[tex]\frac{(120)(3)}{(pi)(0.308)(9.8)}[/tex] = r^3

solve

The radius of the brass ball is equal to 6.94 × 10⁻² m when the tension in the wire is 120 N.

Tension can be demonstrated as the pulling force transmitted by the means of a string, or a rope or can be described as the action-reaction pair of forces acting at each end of said elements.

The tension in the wire attached to the ceiling will be given by:

T = mg ⇒m = T/g

The radius of the brass ball is given by: [tex]r =\sqrt[3]{\frac{3V}{4\pi } }[/tex]

The density is given by: ρ = m/V = T/gV

V = T/gρ

Therefore, the expression for the radius can be written as:

[tex]r =\sqrt[3]{\frac{3T}{4\pi\rho g } }[/tex]

Given the tension in the wire, T = 120 N

The density of the brass is = 8730 Kg/m³

[tex]r =\sqrt[3]{\frac{3\times 120}{4\times 3.14 \times 8730 \times 9.81 } }[/tex]
