Your grandfather has metal-working tools in his workshop and he has helped you to design your own one-person submarine made out of aluminum for you to test out in the local lake. The mass of the submarine is 1,280 kg and its total exterior volume is 9.20 m3. You, of mass 79.0 kg, take the submarine to the lake and climb inside. Determine the volume of water (in m3) that you must allow to enter the holding tanks of your submarine to make it sink.

Marine life such as fish, birds, whales, dolphins and seals are affected by oil spills. Oil sticks to birds preventing them from flying. Whales and dolphins and other creatures that use blow holes can get oil into their respiratory system, making it difficult to breathe. Animals can also ingest the oil. This can become fatal in the short or long term.
