Answer:
<em>0.97c</em>
<em></em>
Explanation:
From the relativistic equation for length contraction, we have
=
where
is the final length of the object
is the original length of the object before contraction
β =
where v is the speed of the object
c is the speed of light in free space = 3 x 10^8 m/s
The equation can be re-written as
/ =
For the length to contract to one-fourth of the proper length, then
/ = 1/4
substituting into the equation, we'll have
1/4 =
substituting for β, we'll have
1/4 =
squaring both side of the equation, we'll have
1/16 = 1 -
= 1 - 1/16
= 15/16
square root both sides of the equation, we have
v/c = 0.968
v = <em>0.97c</em>
I believe it would be orthoclase feldspar, quartz, micas, and amphiboles are the most abundant in granite.<span />
Answer:
The concentration of OH⁻ in the mixture is 0.05 M
Explanation:
The reaction of neutralization between HCl and NaOH is the following:
H⁺(aq) + OH⁻(aq) ⇄ H₂O(l)
The number of moles of HCl is:
Similarly, the number of moles of NaOH is:
Now, from the reaction of HCl and NaOH we have the following number of moles of NaOH remaining:
Finally, the concentration of OH⁻ in the mixture is:
Therefore, the concentration of OH⁻ in the mixture is 0.05 M.

In that email, I will tell my relative in the United states that the transition to capitalism now implies that we work for longer hours with less pay.
<h3>What is capitalism?</h3>
The term capitalism means a system in which the means of production is controlled by individuals rather than by the state. Hence, monopoly is possible in a capitalist economy.
In that email, I will tell my relative in the United states that the transition to capitalism now implies that we work for longer hours with less pay and we do not have the social and job security that was once guaranteed in a socialist/communist economy.
