<span>Pitch and frequency are more or less the same thing - high pitch = high frequency.
The freqency of vibration of a string f = 1/length (L) so as length decreases the frequency increases.</span>
Answer:
17.5
or
1.1 g/min
I know it's one of these, try getting a second opinion
Answer:
The time constants 30 seconds and the can form an RC Charging circuit.
Explanation:
Time constant, τ, is measured in terms of τ = R x C, in seconds, where R is the value of the resistor in ohms and C is the value of the capacitor in Farads
If R = 150 kΩ = 150000Ω
and C = 200 μF = 0.0002 F
τ = 150,000 × 0.0002
<u>= 30 seconds.</u>
A capacitor, (C) connected in series with a resistor, (R) forms a RC Charging Circuit connected across a DC battery supply (Vs) via a mechanical switch, with transient time (time required to charge capacitor) = 5τ
Answer:
The correct answer is -
19 - C) parasitism
20- B) commensalism
Explanation:
Parasitism is a type of symbiotic relationship among two different organisms where one is benefited and the other is harmed. The harmed organism known as the host and the benefitted organism called the parasite. For instance, tapeworms are parasites in the human body.
Commensalism is also a symbiotic relationship but in this relationship, one symbiont is benefitted but another one neither benefitted nor harmed. For instance, Hermit crabs use the shells of dead snails for homes.
