Answer:
a). is lower in elevation than city B
Explanation:
Temperature of a place greatly varies with height or altitudes.
As we go higher the atmospheric pressure becomes less and the temperature decreases. We feel cold at higher altitude places and relatively hot at places of lower elevation. Therefore City A which is at lower elevation has greater annual temperature range than the temperature range of city B although they are located at the same latitude. City A is at lower altitude and City B's elevation is higher. So City A has higher temperature range than city b.
Answer: The theory might have become Obsolete or Superseded
Explanation:
A theory becomes obsolete or superseded if it becomes inadequate, false or incomplete in how its describes reality. It does not matter if it was once accepted. There are some theories such as Lysenkoism that are currently described as being obsolete because it does not conform to current reality. Another example of a theory that was superseded is the phlogiston theory. It was replaced a different theory of energy.
The first step in the formation of sedimentary rock is weathering of preexisting rocks. The second step is transport of the weathering products. The third step is deposition of the material. And at the end there is compaction and cementation of the sediment to form a rock.
According to this, the following shows the correct order of steps in the formation of sedimentary rocks:
C. <span>1, 4, 3, 2
</span>Rocks are weathered.Small pieces of rocks are carried by water.They are deposited in layers.<span>The sediments are compacted together.</span>
Answer:
A. 14.14 m/s²
B. 127.26 m/s
C. 572.67 m
Explanation:
From the question given above, the following data were obtained:
Mass (m) of jet = 4250 kg
Force (F) = 60100 N
A. Determination of the acceleration of the jet.
Mass (m) of jet = 4250 kg
Force (F) = 60100 N
Acceleration (a) =?
F = ma
60100 = 4250 × a
Divide both side by 4250
a = 60100 / 4250
a = 14.14 m/s²
B. Determination of the speed of the jet after 9 s.
Initial velocity (u) = 0 m/s
Acceleration (a) = 14.14 m/s²
Time (t) = 9 s
Final velocity (v) =?
v = u + at
v = 0 + (14.14 × 9)
v = 0 + 127.26
v = 127.26 m/s
C. Determination of the distance travelled during the time.
Initial velocity (u) = 0 m/s
Acceleration (a) = 14.14 m/s²
Time (t) = 9 s
Distance travelled (s) =?
s = ut + ½at²
s = (0 × 9) + (½ × 14.14 × 9²)
s = 0 + (7.07 × 81)
s = 0 + 572.67
s = 572.67 m.
