Can you think of a way a rock unit with an older fossil could be above a rock until with a younger fossil? describe the scenario.

Aspring with a mass of 2 kg has a damping constant 14 kg/s. a force of 3.6 n is required to keep the spring stretched 0.3 m beyond its natural length. the spring is stretched 0.6 m beyond its natural length and then released. find the position of the mass at any time t. (assume that movement to the right is the positive x-direction and the spring is attached to a wall at the left end.)

If a balloon is taken outside on a very cold day, what will occur?
