The correct answer to
the question that is stated above is letter b, <span>Plate tectonics caused lava to flow. All of the options are mentioned in the theories of the formation of the moon except for letter B.
There are 5 serious theories about the formation of the moon,these are:
</span>The Fission Theory--
The Capture Theory--
The Condensation Theory--
The Colliding Planetesimals Theory--
<span>The Ejected Ring Theory--
See attached file for the description of each theory.</span>
Answer:
Time=7.84hrs
Explanation:
This is an inverse proportionality questions
Mathematically time t varies as 1/distance d
Hence T= dk/r
But speed r = distance/t
d= r*t= 9*20=180km/hr
We're k= constant of proportionality
At t=9hrs d=180km/hr
Hence k=r*t/d=20*9/1620=0.111
Finding t at at 1620km for 23km/hr
t=1620*0.111/23=7.84hrs
Are there any options you can choose from?
Answer:
CSP
Explanation:
CSP systems store energy through Thermal Energy Storage technologies (TES), so power can be used when there isn't enough sunlight. PV systems, however, can't store thermal energy because they use direct sunlight, rather than heat. For this reason, CSP systems are better for energy storage and efficiency.
Answer:
three times the original diameter
Explanation:
From the wire's resistance formula, we can calculate the relation between the diameter of the wire and its length:

Here, d is the wire's diameter,
is the electrical resistivity of the material and R is the resistance of the wire. We have
