True. In a wave, a node is a point that remains at zero displacement, meaning that there is no vibration occurring at that specific location. Nodes occur at regular intervals along a wave.
True
False. A convex lens will produce a smaller, upright, and virtual image if the object is placed inside the focal point.
False. An object is in motion if its position changes with respect to a reference point, regardless of whether its distance from the reference point is stationary. Motion includes changes in position, direction, and speed.
False because the difference between it is 180
True. Motion is always measured in relationship to a point of reference. This point of reference can be stationary or moving itself, but it is essential for determining the position, speed, and direction of an object in motion.
True

False. The magnitude of earthquakes is rated on the Richter scale, not the vibration caused by the earthquake. The Richter scale measures the energy released by an earthquake at its source.
