If a musician has plucked a harp string 8 mm to the left that has a spring constant of 15 kg/s^2, what will be the maximum displacement of the harp string in millimetres across its equilibrium position?

How does an observation about an object differ from an inference about that object

0.5 kg of silver increases temperature from 0 celsius to 7 celsius when heat is added how much heat energy produced this change in temperature

1. do the particles in the medium material move in the same direction of the wave or at opposite direction to the wave? explain your answer. 2. by inputting more energy into the wave, i. e a large shake of the spring, which wave property also increases? 3. are there forces of friction acting while a wave is passing through a medium?
