Answer:
The correct answer is - A matter that has an ordered arrangement of atoms, molecules, or ions.
Explanation:
In physics, a crystal is a type of solid matter in which a highly arranged molecule or atoms present to form a lattice that extended in all directions. It is a lightweight clear solid which is normally is colorless.
It can be cubic, hexagonal, triclinic, monoclinic, orthorhombic, tetragonal, and trigonal that are ordered arrangments. Its internal symmetry is visible to its surface.

Answer:
The average force that brings the car to rest is 175000N
Explanation:
The mass of the car, m = 1000 kg
Initial speed, u = 14 m/s
Final speed, v = 0 m/s (Since the car comes to a stop)
The time taken, t = 8 x 10^-2 s
The average force is calculated as:
The average force that brings the car to rest is 175000N
Answer:
Horizontal motion is free from gravity which is zero
