Answer:
1.Free edge
2.Nail Root
3.Nail matrix
4.lunula
Note: The numbering coincides respectively with the dashes in the questions.
Explanation:
Free edge is the distal white nail ending.
Nail Root is the proximal part of the nail embedded in the skin.
Nail matrix is the actively growing part of the nail were the nail root thickens
Lunula the whitish semilunar area of the proximal end of the nail body it appears whitish because stratum basala obscures. the underlying blood vessels.

Explanation:
this is because the key is open
Answer:
Neutrons
Explanation:
Neutrons are subatomic particles that are electrically neutral and possess no charge in them.
G = -10 m/s
s = 0.8 m
v = 0
u = ?
2as = v² - u²
-16 = - u²
u² = 16
u = 4 m/s
Answer: The wave is traveling in the - x direction.
Explanation: The parameter in a wave function determines the direction of the wave is "ωt"
Where ω = angular frequency(in hertz ) and t = time taken (in seconds)
The product of ωt = 2π which is angular displacement in radian.
A negative value of the of ωt means the wave is traveling in the negative direction.
Also a positive value of sin ωt means the wave is traveling in the positive direction
