The ball goes at the highest setting of 2.25cm, which compresses the spring by 3 cm.

Spring is an elastic object that holds mechanical energy. Typically, springs are fabricated from spring steel. Springtime has many different patterns. A conventional spring without stiffness variability features exerts an opposing force that is roughly proportional to its change in length when it is compressed or stretched from its resting state. The word is frequently used to describe coil springs in daily speech (this approximation breaks down for larger deflections). The rate also referred to as the spring constant, is the proportion of a spring's change in force to change in deflection. In other words, it is the force against the deflection curve's gradient.

The algebraic expression for the electric field for a point

We know that,

Φ = Q / ε[tex]_{0}[/tex]

Φ = EA

Q = σ A

where,

Φ = Electric flux

Q = Total charge

ε[tex]_{0}[/tex] = Electric constant

σ = Surface charge density

A = Area

Area of cylinder = 2 π R l

where,

R = Radius of cylinder

l = Length of cylinder

To calculate electric field at a point outside the cylinder, a gaussian surface is considered outside the cylinder with a radius r ( > R ) and length l. The flux on Gaussian cylinder is equal to the charge on surface of the cylinder.

Q = σ 2 π R l

The electric flux on the surface of cylinder is

Φ = σ 2 π R l / ε[tex]_{0}[/tex]

The electric flux on the Gaussian cylinder is

Φ = E 2 π r l

On equating both,

σ 2 π R l / ε[tex]_{0}[/tex] = E 2 π r l

E = σ R / ε[tex]_{0}[/tex] r

This is the equation for electric field at a point outside the cylinder.

To calculate electric field at a point inside the cylinder, a gaussian surface is considered inside the cylinder with a radius r ( < R ) and length l.

E 2 π r l = 0 ( Since there is no flux created inside a closed cylinder )

E = 0

This is the equation for electric field at a point inside the cylinder.

Gauss law states that the total flux outside a closed surface is directly proportional to net charge enclosed by the surface.

Phase contrast microscope shows cells against a bright background and the intracellular structures of unstained cells based on their varying densities.

A technique called phase-contrast microscopy is used to contrast a translucent object without staining it. Phase-contrast microscopy has a number of benefits, including the ability to employ high-resolution objectives, but doing so necessitates a specialised condenser and more expensive objectives.

With the help of the optical contrast technique known as phase contrast, biological specimens' cells can show their unstained architecture. With brightfield illumination, cell structures that appear transparent can be seen in high contrast and in great detail with phase contrast.

A projectile is an object that is launched vertically into the air and moves while being pulled by gravity. A projectile is an object that is launched into the air horizontally and moves regardless of gravity.

G = -9.81 m/s2 is the acceleration of gravity close to the earth. Simply multiply the acceleration of gravity by the period since the object was released to determine the object's speed (or velocity). In other words, velocity is equal to -9.81 m/s2 * time, or V = gt.

From the conversion of energy  =[tex]h=\frac{g t^2}{2}[/tex]

                                                 t = √(2h/g)

If a hypothetical planet is twice as far from the sun as the earth, it should have a time period of 1032 days.

In the early 17th century, Johannes Kepler observed planetary motions and researched them to give three laws known as Kepler’s Laws.

These laws are:

(1) Law of orbits

(2) Law of Areas

(3) Law of Periods

According to the third law, the square of the time period of revolution of a planet around the sun is proportional to the cube of the distance between the sun and the planet, represented by the following  formula

T^2 = r^3

Let T1 be the time period of the revolution of Earth and T2 be the time period of the revolution of the hypothetical planet.

Let r1 be the distance between Earth and the sun and r2 be the distance between the hypothetical planet and the sun.

From the above equation

T1^2 = r1^3

T2^2 = r2^3

Dividing the above equations,

(T1/T2)^2 = (r1/r2)^3

We are given that,

r2 = 2 x r1

And T1 = 365 days

So,

(365/T2)^2 = (r1/2r1)^3

Solving the above equation,

T2 comes out to be 1032 days.

Hence, if a hypothetical planet is twice as far from the sun as the earth, it should have a time period of 1032 days.

4.89g of solid magnesium nitrate (148.3 g/mol) should be added to 500 ml of 0.118 m of sodium nitrate in order to produce an aqueous 0.25 m solution of nitrate ions.

From the given info, we know that there is already the presence of nitrate already mixed in the solution. then we have to find out how more is required to be added to it.

first, we find moles of NaNO3

0.500L x 0.118 M = 0.059 moles NaNO3

this means there are 0.059 moles of[tex]NO^{-} _{3}[/tex]

Here volume is not changing, so amount of moles needed to make this concentration = 0.25M x 0.5L = 0.125 moles

0.125 - 0.059 moles = 0.066 moles of [tex]NO^{-} _{3}[/tex] required to be added in the solution.

for every 1 mole of Mg[tex](NO^{-} _{3} )_ {2}[/tex], there are 2 moles of [tex]NO^{-} _{3}[/tex].

so, we will only need half of the total moles of magnesium nitrate.

converting moles to grams,
