Why does a hollow sphere have more rotational kinetic energy? Another hollow sphere of the same mass and radius is rotating about its axis through the center at the same rotation rate. Which sphere has a greater rotational kinetic energy? The hollow sphere, since the mass is distributed further away from the rotation axis. Does […]
What caused the Izmir earthquake 2020?
What caused the Izmir earthquake 2020? The magnitude 7.0 tremor occurred in an area of complex geological movement, where multiple tectonic plates crack the surface as they jostle for position. Rescue workers and locals search for residents trapped in the debris of a collapsed building in Izmir, Turkey, on October 30, 2020. Why did the […]
What is the Y intercept when given two points?
What is the Y intercept when given two points? Steps Calculate the slope from 2 points. For Example, Two points are (3, 5) and (6, 11) Substitute the slope(m) in the slope-intercept form of the equation. Substitute either point into the equation. You can use either (3,5) or(6,11). Solve for b, which is the y-intercept […]
Why is a decrease in GDP bad?
Why is a decrease in GDP bad? When GDP goes up, the economy is generally thought to be doing well. Meanwhile, weak growth signals that the economy is doing poorly. If GDP falls from one quarter to the next then growth is negative. This often brings with it falling incomes, lower consumption and job cuts. […]
Why are batteries called AA?
Why are batteries called AA? But the most significant difference is size because batteries are called AA & AAA because of their size and dimension. AA doesn’t stand for anything. It is simply an identifier for a battery of given dimensions and nominal voltage. Are C batteries the same as AA? AA batteries are the […]
What does the odometer of an automobile measure which of the following is moving faster?
What does the odometer of an automobile measure which of the following is moving faster? Odometer is an instrument used to calculate the distance travelled by an vehicle in particular period of time. The car will move faster as the speed is in km/hr. How do we calculate the average speed of a car? How […]
What are the signs of infiltration?
What are the signs of infiltration? What are signs of an infiltration/extravasation? Redness around the site. Swelling, puffy or hard skin around the site. Blanching (lighter skin around the IV site) Pain or tenderness around the site. IV not working. Cool skin temperature around the IV site or of the scalp, hand, arm, leg or […]
Is magnetic energy a form of energy?
Is magnetic energy a form of energy? Each magnetic field contains energy, also called magnetic energy. She is a constant in physics. Because a magnetic field is generated by electric currents, the magnetic energy is an energy form of moving charge carriers (electrons). What kind of energy is magnetic energy? Moving a magnet around a […]
Is Moon hotter than Sun?
Is Moon hotter than Sun? Temperatures on the moon are extreme, ranging from boiling hot to freezing cold depending on where the sun is shining. When sunlight hits the moon’s surface, the temperature can reach 260 degrees Fahrenheit (127 degrees Celsius). When the sun goes down, temperatures can dip to minus 280 F (minus 173 […]
Which rock is classified as an evaporite?
Which rock is classified as an evaporite? Minerals in evaporite rocks include carbonates (especially calcite, dolomite, magnesite, and aragonite), sulfates (anhydrite and gypsum), and chlorides (particularly halite, sylvite, and carnallite), as well as various borates, silicates, nitrates, and sulfocarbonates. Which of the following igneous rocks will cool the fastest? Extrusive igneous rocks form above the […]
