Is walking a push or pull? Take walking. We walk by pushing down and backwards on the ground. The ground, obedient slave to the laws of physics that it is, pushes up and forwards on our feet, propelling us along. How do you know that a push or a pull is a force? All forces […]
Why does a swing stop swinging?
Why does a swing stop swinging? When the swing is raised and released, it will move freely back and forth due to the force of gravity on it. The swing continues moving back and forth without any extra outside help until friction (between the air and the swing and between the chains and the attachment […]
What is the best way to identify a igneous rock?
What is the best way to identify a igneous rock? Cooling of the magma can occur beneath the surface (plutonic) or on the surface (volcanic). Igneous rocks can be identified by the determination of the composition and texture of the rock. Once these two characteristics have been identified, the Igneous Rock Identification chart is used […]
How do you reduce 5v to 1.2 V?
What characteristics are used to identify rocks?
What characteristics are used to identify rocks? The following properties are very useful for identification purposes: Hardness. Cleavage. Luster. Color. Streak rock powder. Texture. Structure. What are the common features of rocks? Rocks are made out of minerals and have many different properties, or characteristics. Streak is the color of a rock after it is […]
What determines dream content?
What determines dream content? Theories about why we dream include those that suggest dreaming is a means by which the brain processes emotions, stimuli, memories, and information that’s been absorbed throughout the waking day. There’s a body of study that suggests our waking lives have great influence over the content of our dreams. Is a […]
Which is equal to 0.0079 in scientific notation?
Which is equal to 0.0079 in scientific notation? Therefore, the decimal number 0.0079 written in scientific notation is 7.9 × 10-3 and it has 2 significant figures. What is the scientific notation for 140000000? Why is 140,000 written as 1.4 x 105 in scientific notation? How do you write 0.72 in scientific notation? Therefore, the […]
How do bones muscles and joints work together?
How do bones muscles and joints work together? Muscles can pull bones, but they can’t push them back to the original position. So they work in pairs of flexors and extensors. The flexor contracts to bend a limb at a joint. Then, when the movement is completed, the flexor relaxes and the extensor contracts to […]
What is the charge on the other plate of the capacitor?
What is the charge on the other plate of the capacitor? Capacitors do not store charge. Capacitors actually store an imbalance of charge. If one plate of a capacitor has 1 coulomb of charge stored on it, the other plate will have −1 coulomb, making the total charge (added up across both plates) zero. How […]
Which ocean has strongest currents?
Which ocean has strongest currents? Antarctic Circumpolar Current What happens if deep ocean currents stop? The ocean currents carry warmth from the tropics up to these places, which would no longer happen. If the currents were to stop completely, the average temperature of Europe would cool 5 to 10 degrees Celsius. There would also be […]
