Agroup of students designed an experiment with a thread and a rubber stopper. the steps of the experiment are listed below. 1. tie a rubber stopper to one end of a 20 cm long thread. 2. hold the other end of the thread and whirl it in a circle five times. 3. allow the thread to wind up on the finger. 4. observe that the rubber stopper moves faster as it comes nearer to the finger. the experiment most likely demonstrates (2 points) question 5 options: 1) kepler's first law of planetary motion 2) kepler's second law of planetary motion 3) newton's second law of motion 4) newton's third law of motion

Asolution contains 180 g of glucose (c6h12o6) and 162 g of water. what is the mole fraction of glucose?

Many bird species build nests in which they raise their offspring. one of these species is known as the magnolia warbler. breeding pairs of magnolia warblers build nests out of pieces of grass and twigs. the female warbler will then lay her eggs in the nest and sit on the eggs for a few weeks until they hatch. after the offspring have hatched, the female will continue to sit on the newborn chicks to keep them warm. both the male and the female bring food for the offspring to eat until the young are mature enough to find food on their own. which of these most likely describes why birds such as the magnolia warbler build nests in which to raise their offspring? a. nest building decreases the amount of energy used by the parent birds to raise their offspring to adulthood. b. nest building increases the probability that the offspring will survive and eventually produce offspring of their own. c. nest building decreases the amount of food that the offspring require the adult birds to provide. d. nest building increases the probability of the offspring being located by airborne predators.
