they do not move

they vibrate
C.
they slide around each other
D.

Matter is anything that is made up of atoms. The matter word is mainly used in science. Therefore Option C are correct option.
Matter is a substance that has some mass and can occupy some volume. . Matter can be solid, liquid or gas.
In case of solid, particles are fixed at its mean position, they do not move at all. In gas, particles move very fast. They do not remain at its mean position. They continuously keep on moving with high kineticenergy called Brownian motion. In liquid particles are moveable, they are neither very stiff nor they move very fast. There is surface tension between the particles and the layers of liquid. Therefore, the layers of liquid just slide around each other. And this property of liquid is the reason for its fluidity.
Thus option c is correct option

Answer:
C

Hope this helps :)
Motion can be described in terms of direction, speed, and change. Direction is the course in which the object is moving, speed is the rapidity of the object's movement, and change in motion happens when the speed or direction changes over time.
Motion can be described through three main elements: direction, speed, and change. The direction is the course in which the object is moving, for example, north, south, east, or west in linear motion. The speed is the swift of the object's motion, often calculated in terms such as meters per second, miles per hour etc. Changes in motion, also referred to as acceleration or deceleration, occur when the speed or direction of an object change over a period of time. For an instance, if a car moves from rest and accelerates to 60 miles/hour in 10 seconds, it describes a change in motion.

Apply this kinematics equation for the particle's vertical motion:
D = Vt + 0.5At²
D = vertical distance traveled, t = time, V = initial vertical velocity, A = vertical acceleration
Given values:
D = 49m
V = 34.3m/s
A = -9.81m/s²
Plug in and solve for t:
49 = 34.3t - 4.905t²
4.905t² - 34.3t + 49 = 0
Use the quadratic roots formula to find the values of t:
t ≈ 2, 5
The particle reaches a height of 49m at t = 2s & t = 5s

Answer:
chemical properties because physical properties only change the way an object looks
