What is the momentum of a 30g body moving to the right at a velocity of 2m per sec?
Momentum equals mass times velocity. Mass is traditionally in kilograms, so let's convert those 30 grams into kilograms:
30 g * (1kg / 1000g) = .03 kg
p = mv
so,
p = (.03 kg)(2 m/s)
= .06 kg m/s

How many facesverticesedges do a pyramid have?
A pyramid has at least four faces (a triangular base, with three triangular faces converging at an apex). However, the base of the pyramid can be any polygon.
Given a base of n sides, the pyramid will have n+1 faces, n+1 vertices, and 2n sides.
Thus a pyramid on a pentagonal base would have 6 faces (the base, plus one triangle touching each side of the base), 6 vertices, and 10 sides.

What does action and linking verb mean?
The easy way to recognize a linking verb is that a linking verb acts as an equals sign, the object is a different form of the subject (Mary is my sister. Mary=sister); or the subject becomes the object (My feet got wet. feet->wet).
36 [1] b − 3 = a
[2] 4(a + b) = 10a + b
[3] 4a + 4b = 10a + b
Substitute [1] (b − 3) for a in [3]:
[4] 4(b − 3) + 4b = 10(b − 3) + b
[5] 4b − 12 +4b = 10b − 30 + b
[6] 18 = 3b
[7] 6 = b
[8] 3 = a

If you fold a piece of paper in half 50 times would it reach the moon?
yes the moon is 238,857 miles away whereas a piece of paper folded 50 times reaches over 200,000,000 miles so it would reach the moon (and then some)
Edit: A piece of paper (lets use metric for this) is approx 0.1mm thick.
Folding it 50 times will create a bundle (2^50)/10 mm thick, which is (1.12589907x10^15)/10 mm, or 1.12589907x10^14.
Lets convert it to kilometers, through each step.
Cm : 1.12589907x10^13 (divide by 10)
M : 1.12589907x10^11 (divide by 100)
Km : 1.12589907x10^8 (divide by 1000)
So, the paper would be 1.12589907x10^8 km thick.
The distance from the Earth to the Sun is only 1.496x10^8km.
Therefore, the paper would reach the majority of the way to the Sun... it beat the moon by a long shot.
Plus, if the paper were slightly thicker, (eg 0.11mm) it would reach, or even pass, the Sun quite easily.
