A material that transmits nearly all the light that strikes it
is described as being "transparent", but that has nothing
to do with "resistance to the light", whatever that is.
Even the blackest, densest material, like wood, foil, or concrete,
has no "resistance" to light. It simply absorbs light that enters it,
so some or all of the light that went in one side never made it to
the other side.
Transparent material absorbs very little, so almost all of the
light that goes in one side comes out the other side.
Answer:0.27*10^{6} (m)
Explanation:
with a wave we know that speed= wavelenght* frecuency so
wavelenght= 3*10^{7} / 109 = 0.27*10^{6} (m)
A :-) for this question , we should apply
a = v - u by t
Given - u = -2 m/s
v = -10 m/s
t = 16 sec
Solution -
a = v - u by t
a = -10 - -2 by 16
a = -12 by 16
( cut 12 and 16 because 2 x 6 = 12 and
2 x 8 = 16 )
( cut 6 and 8 because 2 x 3 = 6 and
2 x 4 = 8 )
a = 3 by 4
a = 0.75 m/s^2
.:. The acceleration is 0.75 m/s^2.
To solve this problem we will apply the given concept for torque which explains the relationship between the force applied and the distance to a given point. Mathematically this relationship is given as
Where,
Torque
F = Force
d = Distance
Our values are given as,
Therefore replacing we have that the force is
F = 12.72N
Therefore the least amount of force that you must exert is 12.72N
