Answer:
B) The current of the entire circuit is lowered.
Explanation:
There are two ways in which a resistor can be connected in a circuit;
i) Series: In a series connection, resistors are connected end to end. In this arrangement, the current passing through each resistor is the same while the potential difference across each resistor is different.
ii) Parallel: In a parallel connection, resistors are connected to common junctions. In this arrangement, the potential difference across each resistor is the same while the current across each resistor varies.
In a series circuit, the effective resistance is the algebraic sum of resistance of all the resistors connected in series. Hence, if a large resistor is connected in series, the effective resistance of the circuit is greatly increased.
Since the voltage is given by;
V=IR (Ohm's law)
Where R is the effective resistance
Then;
I = V/R
If R becomes very large due to a large resistance connected in series, then the current of the entire circuit is lowered.
Answer:
Length, l = 0.866 meters
Explanation:
Given that,
Frequency of sound, f = 99 Hz
Speed of sound in air, v = 343 m/s
To find,
The length of a wind instrument.
Solution,
The standing wave will gets formed in wind instrument. For the closed tube, the closed tube the frequency is given by :
Where
l is the length of the instrument
l = 0.866 meters
So, the length of a wind instrument is 0.866 meters. Hence, this is the required solution.
Answer: 
At sea level, there is one standard atmospheric pressure which is equal to 101.325 kilopascals.
The pressure of faintest sound that a human ear can hear is 20 micro-pascals.
taking the ratio of two:
Hence, the atmospheric pressure at sea level is times greater than the faintest sound that a human ear can hear.
it would be appropriate to round a number when you are talking about people or animals. Ex. it fits 10 1/2 people. it will most likely fit 9-11 people.
You it is not appropriate to round with money.
Ex. If you owe someone $9.43 you don't just give them $9
