Answer:

The height or the mass

Explanation:

The one variable that can change the potential energy of a box on the floor is either the height or the mass of the box.

Potential energy is the energy due to the position of a body.

Mathematically;

Potential energy = mass x acceleration due to gravity x height

Therefore, if the mass of the box is changed, the potential energy changes also.

If the position of the box is changed by raising it up, the potential energy changes

Complete Question

A ball having mass 2 kg is connected by a string of length 2 m to a pivot point and held in place in a vertical position. A constant wind force of magnitude 13.2 N blows from left to right. Pivot Pivot F F (a) (b) H m m L L If the mass is released from the vertical position, what maximum height above its initial position will it attain? Assume that the string does not break in the process. The acceleration of gravity is 9.8 m/s 2 . Answer in units of m.What will be the equilibrium height of the mass?

Answer:

$H_m=1.65m$

$H_E=1.16307m$

Explanation:

From the question we are told that

Mass of ball $M=2kg$

Length of string $L= 2m$

Wind force $F=13.2N$

Generally the equation for $\angle \theta$ is mathematically given as

$tan\theta=\frac{F}{mg}$

$\theta=tan^-^1\frac{F}{mg}$

$\theta=tan^-^1\frac{13.2}{2*2}$

$\theta=73.14\textdegree$

Max angle = $2*\theta= 2*73.14=>146.28\textdegree$

Generally the equation for max Height $H_m$ is mathematically given as

$H_m=L(1-cos146.28)$

$H_m=0.9(1+0.8318)$

$H_m=1.65m$

Generally the equation for Equilibrium Height $H_E$ is mathematically given as

$H_E=L(1-cos73.14)$

$H_E=0.9(1+0.2923)$

$H_E=1.16307m$

Use the claim to answer the question.

Pachacha [2.7K]

Scientific evidence such as reflection and photoelectric effect has proven the wave-particle model of electromagnetic radiation to be true.

<h3>What is electromagnet radiation?</h3>

Electromagnetic radiation is radiation produced as a result of the interactions of the electric and magnetic fields.

Some forms of electromagnetic radiation include:

radio waves
microwaves
ultraviolet radiation
visible light

Electromagnetic radiation can be described using a wave model or a particle model.

The wave property of electromagnetic radiation include:

diffraction
reflection
refraction

The particle property of electromagnetic radiation include:

photoelectric effect
Compton effect.

Therefore, the wave-particle model of electromagnetic radiation is correct because it can be backed up by experiments and evidence.
