Question

What data collection type is calc_dB after the following code segment is executed: import math def dB(V1, V2): return 20 * math.log10(V1/V2), V1, V2 calc_dB = dB(10,5)

a.) tuple
b.) Float
c.) set
d.) list

Answer 1

A.) Tuple

Step-by-step explanation:

Multiple values are returned by this function so they are all returned in a tuple.

Answer 2

option a.The variable calc_dB will contain a tuple after executing the given code segment, which includes the dB calculation and the input voltages.

Step-by-step explanation:

After executing the code segment provided, calc_dB will be of type tuple. The function dB is defined to return multiple values, including the result of the logarithmic calculation and the input values V1 and V2. In Python, when a function returns multiple values, they are implicitly returned as a tuple. Hence, when dB(10,5) is called and its return values are stored in the variable calc_dB, this variable will be holding a tuple consisting of the decibel calculation and the original voltage values 10 and 5.

The data collection type of calc_dB after the execution of the code segment is a float.

When the dB function is called with arguments 10 and 5, the V1/V2 expression returns 2.0. The math.log10 function computes the base 10 logarithm of 2.0, which equals 0.30103. Finally, multiplying the result by 20 gives a final value of 6.0206 for calc_dB.

Since the result is a single value, it is stored as a float data type.
