What is the total resistance of a 6 ohm and a 8 ohm resistor connected in series? (1 Point)

Oksanka [162]

Answer:

Total Resistance in circuit is Fourteen Ohms (14 Ω).

Explanation:

How do we know, if the resistors are connected in series, the total resistance is the sum of all the resistors.

(Important: The total resistance can only be added just when the resistors are connected in series)

Then, total resistance (TR ) is the sum of all resistors (T1 + T2, in this case)

TR = T1 + T2

According to problem data, we have:

TR = 8 Ω + 6 Ω

TR = 14 Ω

Answer:

Mass of banana is $1.12$ Kg

Explanation:

Step 1: Determine the equation of speed of an object moving in an harmonic motion

Speed of moving in an harmonic motion is given by

$v = \sqrt{\frac{k}{m} (A^2 -x^2)} \\$

Here, v represents the speed of the object in harmonic motion, k is the springs constant, m is the mass of the object, A is the amplitude, and x is the position.

In this question , $x = 0$ because only at this position maximum speed occurs

So the simplified equation becomes -

$v = \sqrt{(\frac{k}{m} * A)}$

$m = \frac{kA^2}{v_(max)^2}$

Substituting the given values in above equation we get -

Assume spring constant is $16$ N/m

$m = \frac{16 * 0.14}{2} \\m = 1.12$

Mass of banana is $1.12$ Kg
