Answer:
0.6983 m/s
Explanation:
k = spring constant of the spring = 0.4 N/m
L₀ = Initial length = 11 cm = 0.11 m
L = Final length = 27 cm = 0.27 m
x = stretch in the spring = L - L₀ = 0.27 - 0.11 = 0.16 m
m = mass of the mass attached = 0.021 kg
v = speed of the mass
Using conservation of energy
Kinetic energy of mass = Spring potential energy
(0.5) m v² = (0.5) k x²
m v² = k x²
(0.021) v² = (0.4) (0.16)²
v = 0.6983 m/s
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.
What? im so confused lol. the force is y=mx+b
Loudness<span> refers to how loud or soft a </span>sound<span> seems to a listener. The </span>loudness<span> of </span>sound is<span> determined, in turn, by the </span>intensity<span>, or amount of energy, in </span>sound<span> waves. The unit of </span>intensity is<span> the decibel (dB). As decibel levels get higher, </span>sound<span> waves have greater </span>intensity<span> and </span>sounds are<span> louder.</span>
