Answer: 0.798 m

Explanation:

Given

Mass of the spring oscillator, m = 1.48 kg

Force constant of the spring, k = 35.4 N/m

Speed of oscillation, v = 3.9 m/s

Kinetic Energy = 1/2 mv²

Kinetic Energy = 1/2 * 1.48 * 3.9²

KE = 0.5 * 22.5108

KE = 11.26 J

Using the law of conservation of Energy. The Potential Energy of the system is equal to Kinetic Energy of the system

KE = PE

PE = 1/2kx²

11.26 = 1/2 * 35.4 * x²

11.26 = 17.7x²

x² = 11.26 / 17.7

x² = 0.6362

x = √0.6362

x = 0.798 m

Describe how the amount of voltage applied to a circuit affects current flow. A) Current and voltage of a circuit are indirectly
Nookie1986 [14]

Increasing the voltage will increase the current proportionately. (C)

That's just Ohm's Law:

<em>"The current through a circuit is directly proportional to the voltage across the circuit.  The proportionality constant is the reciprocal of the circuit's resistance."</em>
