What is an ordered arrangement of particles extends over a long distance in a solid, the material is called?

Crystalline

Explanation:

A crystalline solid  consist of atoms , molecules and ions that possess a definite repetitive pattern.The crystal structure depict the microscopic arrangement of atom inside it. The constituent(molecules, ions and atoms) that makes up the crystals are well ordered  forming a crystal lattice in all direction.

The pattern of formation of the crystals are repetitive. The process of formation of this crystal structure is known as crystallization. Not all solid are crystal  form example glass and ice.  This orderly arrangement of the particles in the solid usually exist through out the solid.  This solid are characterize by long range order with a small repeat unit . The pattern of array is called the crystal lattice. Example of crystalline solid is salt.

first let us lay out the formula for potential

and kinetic energy:

pe = mgh

ke = (mv^2)/2

where: m=mass, v=velocity, g=gravitational

acceleration, h=height

calculating for mass using the known values of

pe:

340j = m (9.81 m/s^2) (50ft) (1m/3.28ft)

m = 2.27 kg

the law of conservation of energy states that

energy is neither created nor destroyed. therefore, the change in kinetic

energy from 50 ft to 35 ft would be equal to the change in potential energy

from 50 ft to 35 ft. however it would be opposite in signs since one is losing

while other is gaining.

ke(35ft) – ke(50ft) = - [ pe(35ft) – pe(50ft]

ke(50ft) = 0 since the brick is initially at rest

ke(35ft) = 340j - 2.27kg (9.81 m/s^2) (35ft)

(1m/3.28 ft)

ke(35ft)

= 102.38 j
