Answer:
0.23 s
Explanation:
First of all, let's find the time constant of the circuit:
where
is the resistance
is the capacitance
Substituting,
The charge on a charging capacitor is given by
(1)
where
is the full charge
we want to find the time t at which the capacitor reaches 90% of the full charge, so the time t at which
Substituting this into eq.(1) we find
Answer:
becomes narrower
Explanation:
Confidence intervals for the population mean μ and population proportion p becomes narrower as the size of the sample increases.
As,the sample size increases,standard error decreases,so margin of error decreases and hence width of CI decreases.
I believe the correct answer from the choices listed above is option D. During the condensing phase that the <span>arrangement of water molecules become more orderly. Condensation is the phase change from gas to liquid. Liquid molecules has more order than the gas state. Hope this answers the question.</span>
Answer:
Q1. Young rocks are found on top, and old layer are found on the bottom.
Q2. Layers of sedimentary rock. Fossil layers are fossils that formed in sedimentary rock. When, over a long time, layers and layers of sediments get deposited on top of each other, the weight of the top layers presses down on the bottom layers, forming them into rock called sedimentary rock
Explanation:
Sedimentary rocks are deposited one on top of another. Therefore, the youngest layers are found at the top, and the oldest layers are found at the bottom of the sequence.
Answer : D
Reason : The more waste being brought into an area the more waste being spread across the land.
