Activity 1.1 // Observing and classifying Collect different types of fruits such as oranges, bananas, grapes, lemons, apples, papayas, walnut, chestnut, coconut, gooseberry, etc. Observe their colour, shape, size, smell, taste, and hardness using your senses. Your eyes can find colour, shape and size, nose detects smell, hand (skin) detects hardness and tongue determines taste. Classify fruits: Put the similar fruits in one place and separate different fruits in different places. Fruits with similar shape Fruits with similar taste Fruits with similar hardness Fruits with similar colour Now conclude your finding based on the above observation. e. g. 1.Fruits do not have the same taste. They can be sweet, sour, or even tasteless. 2. 3.​

Your starship, the aimless wanderer, lands on the mysterious planet mongo. as chief scientist-engineer, you make the following measurements: a 2.50-kg stone thrown upward from the ground at 14.0 m/s returns to the ground in 5.70 s ; the circumference of mongo at the equator is 2.20×10^5 km ; and there is no appreciable atmosphere on mongo. (a) the starship commander, captain confusion, asks for the following information: what is the mass of mongo? (b) if the aimless wanderer goes into a circular orbit 2.20×10^4 km above the surface of mongo, how many hours will it take the ship to complete one orbit? (c) an unmanned spacecraft is in a circular orbit around the moon, observing the lunar surface from an altitude of 44.0 km . to the dismay of scientists on earth, an electrical fault causes an on-board thruster to fire, decreasing the speed of the spacecraft by 23.0 m/s . if nothing is done to correct its orbit, with what speed (in km/h) will the spacecraft crash into the lunar surface?
