Answer:
By plotting the locations of earthquakes
Explanation:
When plotting the locations of earthquakes, scientists have been able to locate plate boundaries and also be able to determine plate characteristics and predict the movement of plates
A. The formula for mean free time is:
t = V/(4π√2 r²vN)
where
N = 1×10¹⁶ molecules (per m³)
V = 1 m³
r = 111×10⁻⁷m (atomic radius of silicon)
Let's solve for v first:
v = √(3RT/M) = √(3(8.314 m³·Pa/mol·K)(25 + 273 K)/28.1 g/mol Si)
v = 16.26 m/s
t = (1 m³)/(4π√2 (111×10⁻⁷m)²(16.26 m/s)(1×10¹⁶ molecules))
<em>t = 2.81×10⁻9 s</em>
<em>Pure silicon has a high resistivity relative to copper because copper is a conductor, while silicon is a semi-conductor. </em>
You should move this to Biology. Sorry I can't give you an answer though. Its been years since I have taken Biology.
If I had to guess though I would think the answer would be B. Take that with a grain of salt though.
It slows down. The molecules/particles aren't as close together, resulting in slower movement.
Answer:
The displacement of the photographer and the astronauts are equal
Explanation:
In this exercise, it is important to differentiate between distance and displacement.
The distance moved by an object describes the total length of change in position irrespective of the objects starting point or the point where the transit stops. Distance is a scalar quantity as it does not specify a direction of which a transit takes place as such a piston moving in oscillatory motion can be said to cover a very long distance considering its number of completed cycles
Displacement unlike distance is a vector quantity which accounts for an objects starting and ending points regardless of the route through which the object completed the distance, as such it is the straight line linking the object starting and stopping points, of which the length of the line is the magnitude of displacement and the direction from the starting point to the end point
As such in the above question the displacement of the photographer is his transit from Florida to California while the displacement of the astronauts is also from Florida and stopping at California both of which are equal
