Unknown, because the mass of thecluminum sample was not provided.unpunsaddoD. Yes, because the density of aluminumdoesn't change based on the size ofthe sample.105gAnswer.Why:Tuesday 4/19Students are given three cubes made of unidentified materials. They needto determine whether or not the three cubes are made of the same material.They measure the mass of each cube and record it in the table. A studentimmediately concludes that the cubes are made of three different materíals..CubeMass (g)4215B.C.7.What observation would best support the students' conclusion?A. The cubes all have the same volume.B. The cubes all have a shiny appearance.C. The cubes are all attracted to a magnet.D. The cubes all conduct heat.Wednesday 4/20Janet and Ahmad are both doing a science project about.growing grass. They both sprinkle grass seed on a boxof soil 10 cm by 15 cm by 5 cm deep. They plant their grass seed on the same day. They water the seeds with50 mL of water every other day. After four days, the grass.seed sprouts. After three weeks, Ahmad's grass is 2cm taller than Janet's. What might account for the difference in growth rates?A. the amount of.sun each box receivedB. the time of year the students planted the grassC. the box of soil Ahmad used for planting was much larger than Janet's soil boxD. the number of seeds Ahmad planted was greater than the number Janet planted

For this problem, we want to estimate the answer, so our assumptions may be a little unrealistic. Suppose we want to estimate how much air we need to send to a space station, assuming we cannot recycle air. Suppose four astronauts are in a spherical space station. If each of them typically breathes about 500 cm³of air with each breathe, and take 15 breathes per minute (average resting value): a. What is the volume of air you would need in the space station if these four astronauts stayed for a full year? b. If the density of air is 1.25 kg/m³ and it costs (thanks to SpaceX) a mere $100/kg to send objects to the space station, how much money would the astronaut air supply cost?
