What is the direction of magnetic field at a point? Magnetic field lines are defined to have the direction that a small compass points when placed at a location. (a) If small compasses are used to map the magnetic field around a bar magnet, they will point in the directions shown: away from the north […]

Is 50 Cent or 50 greater? 50 degrees Celsius is hotter than 50 degrees F. 50 degrees Celsius is half way between freezing and boiling. Which is greater 50 Celsius or 50 F? Because in Kelvin scale 50°C is equivalent to 323K while 50°F is equivalent to 283K. That is why 50°C is greater than […]

What did Prince Henry discover? After procuring the new caravel ship, Henry was responsible for the early development of Portuguese exploration and maritime trade with other continents through the systematic exploration of Western Africa, the islands of the Atlantic Ocean, and the search for new routes. Who went to Prince Henry’s navigation school? The last […]

How do you explain anomalous results? Anomalous results are odd results – those which are not in keeping with the rest of the results or which do not follow any correlation you have spotted. If you have repeated your experiment several times, you will usually find fewer anomalous results than if you carry it out […]

Do objects float better in hot or cold water? Cooling a substance causes molecules to slow down and get slightly closer together, occupying a smaller volume that results in an increase in density. Hot water is less dense and will float on room-temperature water. Cold water is more dense and will sink in room-temperature water. […]

What are the 7 steps to the scientific method? Let’s build some intuition for the scientific method by applying its steps to a practical problem from everyday life. Make an observation. Ask a question. Propose a hypothesis. Make predictions. Test the predictions. Iterate. What are the six scientific method? Test the hypothesis and collect data. […]

What are the 5 biomes in the nether? Nether Biomes: Basalt Delta, Crimson Forest, Nether Wastes, Soul Sand Valley, Warped Forest. Previously, the Nether looked pretty much the same no matter where you went. Is Netherite in bedrock? With the new Nether update for Minecraft, the strongest material in the game has shifted from Diamond […]

Where is the location of Sun in Milky Way galaxy? Bottom line: The sun is about 1/3 the distance from the center of the Milky Way galaxy to its outer edges. It’s located in a smaller spiral arm, between two large arms, called the Orion Arm. Where are we located in the Milky Way quizlet? […]

What is the formula for NH4 and O? NH₄⁺ Is NH4 an acid or base? Weak base dissociation eg NH3 NH3 is a weak base and dissociates partially in solution (as indicated with reversible arrow) to form OH- and NH4+ ions. Since this is a reversible process, NH4+ can donate H+ to form back NH3. […]

What particle size is the easiest to erode? In a stream, the most easily eroded particles are small sand grains between 0.2 mm and 0.5 mm. Anything smaller or larger requires a higher water velocity to be eroded and entrained in the flow. What increases the size of particles carried increases? The average velocity (speed) […]
