Please do help me with this please. This is a physics question. Nevermind the solution, i only need the correct letter of the answer.

How much force is needed to pull a spring with a spring constant of 19.7 N/m a distance of 20.8 m? 409.76 N O 40.50 N O 410 N O 0.95 mWhich of the following is NOT true regarding the mass, volume and density of an object? O An object with a larger volume is heavier compared to an object of the same material but smaller volume. A denser object has more weight compared to a less dense object of equal volume. O An object with lesser volume is denser compared to an object of equal mass but with larger volume. O Less dense object has less volume compared to a denser object of equal weight.Which of the following must be true about the force constant of a spring? The greater the force constant of the spring, the greater the elongation of the spring when it is stretched or compressed. The ratio between the stretching or compressing force to the elongation of the spring is not constant. The greater the force constant of the spring, the harder it is to stretch or compress it from its equilibrium length. The greater the force constant of the spring, the greater the elongation of the spring when it is stretched or compressed
