In a parallel circuit the current A stays in one path B splits and goes through two components C makes one circle
ArbitrLikvidat [17]

Answer:

B splits and goes through two components

Explanation:

- A series circuit is a circuit in which the components are all connected along the same branch: as a result, the current flowing through the components is the same, while the sum of the potential differences across each component is equal to the emf of the battery

- A parallel circuit is a circuit consisting of separate branches, so that each branch has a potential difference equal to the emf of the battery. As a result, in such a circuit the current in the circuit splits and goes through the different branches/components.

So, the correct answer is

B splits and goes through two components

A bat emits a sound at a frequency of 30.0 kHz as it approaches a wall. The bat detects beats such that the frequency of the ech
Alex

Answer:

The speed of the bat is 5.02 m/s.

Explanation:

Given that,

Frequency = 30.0 kHz

Frequency of echo = 900 Hz

We need to calculate the frequency

Using formula of beat frequency

f_{b}=f_{1}-f_{2}

Put the value into the formula

900=f_{1}-30\times10^{3}

f_{1}=900+30000

f_{1}=30900\ Hz

We need to calculate the speed of the bat

Using Doppler equation

f_{apr}=f\times(\dfrac{v_{sound}+v_{observer}}{v_{s}-v_{source}})

Put the value into the formula

30900=30000\times(\dfrac{340+v_{bat}}{340-v_{bat}})

\dfrac{30900}{30000}=\dfrac{340+v_{bat}}{340-v_{bat}}

1.03=\dfrac{340+v_{bat}}{340-v_{bat}}

340\times1.03-340=v_{b}+1.03v_{b}

10.2=2.03v_{bat}

v_{bat}=\dfrac{10.2}{2.03}

v_{bat}=5.02\ m/s

Hence, The speed of the bat is 5.02 m/s.
