Answer:
A.Amorphous solid
Explanation:
There are two states used to describe solids in science; these are crystalline and amorphous (non-crystalline) solids.
Crystalline solids are solids whose constituent particles are properly arranged in a 3-dimensional structure in a crystal-like manner. They have a definite melting point and a defined shape and pattern. A common example of a crystalline solid is diamond.
Amorphous or non-crystalline solids are the opposite of the crystalline solids as there constituent particles are disorderly arranged. They do not have a defined melting point as they melt over a range of temperature.
From the above, it can be deduced that candle wax exhibits the properties of amorphous solids. give me brainliest please

What is the distance?</h3>
- Distance is a measure of how far apart two objects or locations are using numbers.
- The distance can refer to a physical length or an estimate based on other factors in both daily language and physics (e.g. "two counties over").
- The terms "distance from A to B" and "distance from B to A" are frequently used interchangeably.
- A distance function or metric is a technique to describe what it means for components of space to be "near to" or "far away" from each other in mathematics.
- It is a generalization of the idea of physical distance. Distance is a non-numerical unit of measurement in psychology and the social sciences; psychological distance is the separation of an object from itself along dimensions including time, space, and isolation.
We know that
the magnetic field is inversely proportional to distance.

Answer:
Jim's kinetic energy is 54.67 J.
Explanation:
Given that,
Mass, m = 15 kg
Velocity, V = 2.7 m/s
We need to find the Jim's kinetic energy. We know that when the object is in motion, it has kinetic energy. This energy is given by :
E = 54.67 J
So, Jim's kinetic energy is 54.67 J. Hence, this is the required solution.
Answer and Solution:
As per the question:
The particle's displacement is given by the expression:
Now,
(a) The average velocity is given as the ratio of the displacement of the particle to the time interval:
Now, displacement in the interval:
i) [3,4]
At t = 3 s
At t = 4 s
ii) [3.5, 4]
At t = 3.5 s
At t = 4 s
iii) [4, 5]
At t = 4 s
At t = 5 s
iv) [4, 4.5]
At t = 4 s
At t = 4.5 s
(b) The instantaneous velocity at t = 4 s is given by:
At t = 4 s
To solve this problem, it is necessary to apply the concepts related to the change of entropy in function of the Volume in two states due to the number of moles and the ideal gas constant, this can be expressed as
Where,
R = Gas constant
V = Volume (at each state)
At the same time the number of moles of gas would be determined by the ideal gas equation, that is,
Where,
P = Pressure
V = Volume
R = Gas Constant
T = Temperature
Using the value of moles to replace it in the first equation we have
Therefore the correct option is A.
