What happens when satellites crash? The Short Answer: Two things can happen to old satellites: For the closer satellites, engineers will use its last bit of fuel to slow it down so it will fall out of orbit and burn up in the atmosphere. Further satellites are instead sent even farther away from Earth. How […]
How does a roller coaster go up a hill?
What is a high resistance wire?
What is a high resistance wire? Resistance wire is used to control the amount of current in a circuit. High resistivity is better since a shorter wire can then be used. When it is used for heating elements for applications such as electric heaters and toasters, high resistivity and oxidation resistance is important. What’s the […]
How do you calculate sound pressure?
How do you calculate sound pressure? Sound pressure level (SPL) calculator – formula & step by step calculation to measure the logarithmic RMS value of the sound or acoustic pressure caused by the sound wave relative to a reference value in decibels. SPL (dB) = 10 log10(p2/po2). How do you convert pressure to dB? Sound […]
How can Brendan correct his diagram?
How can Brendan correct his diagram? Brendan drew a diagram to illustrate the centripetal force acting on a satellite. How can Brendan correct his diagram? Change the Fg = Fc vector so it is perpendicular to the v vector. Enrique is given information about a satellite orbiting Earth. What additional information does Hannah need in […]

According to the Hindu epic Mahabharata, a city called Indraprastha, “City of the God Indra”, was the capital of the Pandavas. According to Indian epic Mahabharatha, Delhi was the site of the […]
What type of bond is potassium sulfur?
What type of bond is potassium sulfur? ionic bond What is the bond between potassium and sulfur? The difference in charge between the two 1+ potassium ions and the 2- sulfur ion allows electrostatic attraction between the sulfur ions and potassium ions. This is an ionic bond and is the basis of the ionic compound […]
What is the difference between the bell and the diaphragm of a stethoscope?
What is the difference between the bell and the diaphragm of a stethoscope? The bell effect is created by light pressure on the stethoscope. Firm pressure makes the stethoscope behave like it should with a diaphragm. The difference between the diaphragm and the bell is that the bell allows low frequency sounds, which permits hearing […]
What is radius of curvature in light?
What is radius of curvature in light? Radius of curvature (ROC) has specific meaning and sign convention in optical design. A spherical lens or mirror surface has a center of curvature located either along or decentered from the system local optical axis. The distance from the vertex to the center of curvature is the radius […]
Which is older intrusion or extrusion?
Which is older intrusion or extrusion? Lava that hardens on the surface is called an extrusion. The rock layers below an extrusion are always older than the extrusion. There, the magma cools and hardens into a mass of igneous rock called an intrusion. An intrusion is always younger than the rock layers around and beneath […]
