Answer:
a = (v₃₂ - v₂₁) / (t₃₂ -t₂₁)
Explanation:
This is an exercise of average speed, which is defined with the variation of the distance in the unit of time
v = (y₃ - y₂) / (t₃-t₂)
the midpoint of a magnitude is the sum of the magnitude between 2
t_mid = (t₂ + t₃) / 2
the same reasoning is used for the mean acceleration
a = (v_f - v₀) / (t_f - t₀)
in our case
a = (v₃₂ - v₂₁) / (t₃₂ -t₂₁)
Answer:
conduction electrons
Explanation:
Metallic bonding is a type of chemical bonding that rises from the electrostatic attractive force between conduction electrons and positively charged metal ions. It may be described as the sharing of free electrons among a structure of positively charged ions.
For the total internal reflection of a substance, we can express the relationship between the critical angle,
, and the indices of refraction as
(1) <span>
</span>
where
and
are the indices of refraction. And under polarization, we can express Snell's Law as
Rearranging this we have
(2)Substituting equations (1) into (2), we have
Substituting the value of the critical angle, we have
Answer: 33.79°
The answer is stomata. The process through which this occurs is known as transpiration.
