5. What things would settle in pond water, making it turn to land (terrestrial) succession?

alekssr [168]

Answer:

Organic matter

Explanation:

As organic matter continue to build up in a pond, vegetation will begin to appear in the pond. The first set of vegetation to appear are the floating vegetation. Subsequently, submersed plants begin to grow also.

With time, organic sediments continue to fill the pond and its depth is gradually decreased. A swamp or bog is now formed.

This trend of succession continues until the pond eventually turns into land.

How fast can the 140 a current through a 0.200 h inductor be shut off if the induced emf cannot exceed 80.0 v?

Vesna [10]

Recall that to compute for the emf of a circuit given current and inductance, we must recall that

$emf = - M \frac{\Delta I }{\Delta t}$

where I is the current (A), M is the mutual inductance (h), and t is the time (ms). Since the current must not exceed 80.0 V, we have

$80.0 \geq 0.200(\frac{140}{t})$
$t \geq \frac{28.0}{80}$
$t \geq 0.35$

From this, we see that it must take at least 0.35 ms so it doesn't exceed 80 V.
Answer: 0.35 ms

9. A wave on Beaver Dam Lake passes by two docks that are 40.0 m apart.

Kobotan [32]

Answers:

a) 10 m

b) time=1.6 s, frquency=0.625 Hz

c) 6.25 m/s

Explanation:

a) If there is a crest at each dock and another three crests between the two docks, and the wavelength $\lambda$ is the distance between to crests; this means we have $4\lambda$ in $40 m$ :
