Answer:
It simply means that, the pencil is long enough to attain a length of six (6) centimeters when measured with a measuring tool such as a ruler, tape, etc.
Explanation:
A scientific method can be defined as a research method that typically involves the use of experimental and mathematical techniques which comprises of a series of steps such as systematic observation, measurement, and analysis to formulate, test and modify a hypothesis.
Measurements refers to a process which typically involves identifying and determining the dimensions of a physical object. The dimensions include important parameters such as width, height, length, area, volume, circumference etc.
Hence, a pencil whose length is measured as 6 centimeters has a physical dimension that covers a distance of six (6) centimeters in terms of size.
In conclusion, the pencil would cover a length of six (6) centimeters when measured vertically and a corresponding height of six (6) centimeters when measured horizontally.
The potential energy of a 2-μc charge at that point in space is 
joules.
Given,
V=400v, q=2-μc=2*
,
U(potential energy)=V*q=400*2*= joules.
<h3>Potential energy</h3>
The energy that an item retains due to its position in relation to other objects, internal tensions, electric charge, or other reasons is known as potential energy in physics. The gravitational potential energy of an object is based on its mass and the distance from the centre of mass of another object. Other common types of potential energy include the elastic potential energy of an extended spring and the electric potential energy of an electric charge in an electric field. The joule, denoted by the sign J, is the SI's definition of an energy unit.
The vectors that are described as gradients of a particular scalar function known as potential can be used to represent these forces, also known as conservative forces, at any location in space.

Answer:
-969.06
-286.74
698.7
-115.6, 12.9
-139.9, 12.9
Explanation:
Given that
Speed v, wrt y = -24.3 m/s
Speed v, wrt x = 12.9 m/s
time t, = 11.8 s
a
Using the formula
H(t) = ut - 1/2gt², where u = v wrt y
H(t) = -24.3 * 11.8 - 1/2 * 9.8 * 11.8²
H(t) = -286.74 - 682.28
H(t) = -969.06 m
b
H = ut, where u = v wrt y
H = -24.3 * 11.8
H = -286.74 m
H(1) = -969.06 - -286.74 = -682 m
c
Horizontal displacement, x = vt. Where v = v wrt x
x = 12.9 * 11.8
x = 152.22 m
d = √(H1² + x²)
d = √682² + 152²
d = 465124 + 23104
d = √488228
d = 698.7 m
d
Vertical component =
-gt - 0 =
-9.8 * 11.8 = -115.6
Horizontal component =
v wrt x - 0
12.9 - 0 = 12.9
e
Vertical component =
-gt - v wrt y =
-9.8 * 11.8 - 24.3 = -139.9
Horizontal component =
v wrt x - 0 =
12.9 - 0 = 0
