It will always produce a near-exact measurement
The temperature is 293.15k
Answer:
It declined drastically
Explanation:
The moths were active at night and rested by day on white birch trees, where they were effectively camouflaged from predators.
However, as the city became more industrialized, the trees were covered with black soot from the factories.
The white moths lost their camouflage, so their population declined drastically, as their predators could now find them more easily.
Answer:
Explanation:
Applying the Heisenberg uncertainty principle,
Δx X mΔv = h/4π
where Δx = uncertainty in measurement of position
Δv = uncertainty in measurement of velocity
m = mass of object
h = planck's constant
Here:
Δv = 0.4 A° = 4.0 x 10^-11 m
mass, m = 9.11 x 10^-31 Kg
Plugging the values,
4.0 x 10^-11 x Δ v = (6.626 x 10^-34) / (4 x 3.14 x 9.11E-31)
4.0 x 10^-11 x Δ v = 5.791 x 10^-5
Δv = 1.448 x 10^6 m/s, the uncertainty in its velocity
Answer = 1.45 x 10^6 m/s
