The average kinetic energy of the particles of two pieces of iron at the same temperature and mass would be __________.
Question 1 options:
Different
The same
Not equivilent
With in 500 degrees of eachother
Answers
Answer:
The same.
Explanation:
Temperature is a measure of the average kinetic energy of a substance; if two pieces of iron have the same temperature, then their particles will have the same amount of average kinetic energy.
Answer 1 - The average kinetic energy of the particles of two pieces of iron at the same temperature and mass would be the same
Answer 2 - The particles of an object move FASTER when the temperature increases
Answer 3 - When a tight fitting lid is run under hot water, the lid

. ........... is a mirror with a flat reflecting surface and is made of ordinary glass.
Answers
Answer:
Plane mirror.
Explanation:
A plain mirror is a mirror with a flat reflecting surface and is made of ordinary glass.
Reflection can be defined as a phenomenon which typically involves a change in the direction of a ray of light or waves as it falls on a smooth surface.
Simply stated, reflection occurs when a ray of light or wavefronts bounces off a smooth surface such as a plane mirror.
Generally, the angle of reflection equals the angle of incidence when a light ray strikes or hits a plane mirror.
The properties or characteristics of the images formed by a plane mirror include;
I. They are virtual and erect (upright).
II. It is the same size as the object formed.
III. It has the same distance from the plane mirror as the distance of the object from the mirror.

(D is interference)
Answers
The phenomenon of interference occurs when two wave pulses are traveling along a string toward each other. Option D is correct.
What is the interference of waves?The result of two or more wave trains flowing in opposite directions on a crossing or coinciding pathways. This phenomenon is known as the interference of waves.
The effect is the sum of the individual wave amplitudes at each site where more than one wave is present.
When two wave pulses are traveling along a string toward each other. They meet and the phenomenon is occur known as interference.
Hence the phenomenon of interference occurs when two wave pulses are traveling along a string toward each other.

What happens to the force between charged and uncharged objects as the distance between them decreases?
Answers
Answer:Thus, if each of the charges were reduced by one-half, the repulsion would be reduced to one-quarter of its former value. Also In electrostatics, the electrical force between two charged objects is inversely related to the distance of separation between the two objects. ... And decreasing the separation distance between objects increases the force of attraction or repulsion between the objects.
Hope this helps have a awesome night/day❤️✨
Explanation:
Nothing, until those two objects physically touch each other; contact aligns polarity among the now single shared mass.
(Your question never states if both objects are unique or similar polar charges, so I just assumed they were both neutral objects existing within an electric field.)
So a better question would then be, what is gravity’s relationship with an electric field?
You could solve this with the following: confine the electric field’s volume to a set variable (never increasing nor decreasing in size or shape); density is variable and easily definable. This creates the limit to build upon. This density has to be fluid and has electron mass (full of electrons at rest mass, so with substance but no movement). Within, create a closed system (the hard part in this equation; outside interference like ambient light will eschew results) where each variable of kinetic energy then is accounted for or measurable (including heat and light, and the physical movement of the two objects)
Determine the mass for both objects, calculate gravity for both and each body’s inertia on the other as a sum over distance. record results. Polarity is shared across the masses until there is no longer inertia (one mass or contact).
