Answer:
At the plate boundary, there would be a divergent boundary where we can see a mid ocean ridge and a gap. We would be able to see the mantle because there would be a fissure from where magma will rise and solidify.
Explanation:
Under the South American plate and African plate, there are currents that cause a divergent boundary. They create this boundary since they pull the tectonic plates apart, causing a mid-ocean ridge with an opening that allows the rising of the magma that was underneath. Once that the magma is out, it solidifies, and the currents will try to create another ridge to repeat the process.
When the plates are apart, the mantle that is beneath is exposed, and we can see the magma.
All you have to do is multiply 68 miles and 3.2 hours. It will give you the answer, 217.6 mph.
68x3.2=217.6 miles per hour.
Answer: beta, gamma, alpha
Explanation: Beta is weakest gamma is middle alpha is strongest
Answer:
Final temperature is 302 K
Explanation:
You can now initial volume with ideal gas law, thus:
V = 
Where:
n are moles: 2 moles
R is gas constant: 0,082 
T is temperature: 300 K
P is pressure: 1 atm
V is volume, with these values: <em>49,2 L</em>
The work in the expansion of the gas, W, is: 1216 J - 34166 J = <em>-32950 J</em>
This work is:
W = P (Vf- Vi)
Where P is constant pressure, 1 atm
And Vf and Vi are final and initial volume in the expansion
-32950 J = -1 atm (Vf-49,2L) × 
Solving: <em>Vf = 49,52 L</em>
Thus, final temperature could be obtained from ideal gas law, again:
T = 
Where:
n are moles: 2 moles
R is gas constant: 0,082 
P is pressure: 1 atm
V is volume: 49,52 L
T is final temperature: <em>302 K</em>
