Why is the epicenter important? Hereof, why do we need to know the epicenter of an earthquake? The main importance in determining the epicentre is so that the fault that ruptured causing the earthquake can be identified. If the fault is a recognised fault, then the earthquake can be used to increase confidence in the […]

What does mean absolute percentage error tell you? The mean absolute percentage error (MAPE) is a measure of how accurate a forecast system is. It measures this accuracy as a percentage, and can be calculated as the average absolute percent error for each time period minus actual values divided by actual values. What does mean […]

What is example of static friction? Static friction is a force that hinders the movement of an object moving along the path. When two fabrics slide over each other, this friction occurs. There’s friction all around us. When we walk, for instance, our feet are in touch with the floor. What causes static friction? Static […]

What is the difference between longitudinal cross transverse and horizontal cuts? The sagittal plane or lateral plane (longitudinal, anteroposterior) is a plane parallel to the sagittal suture. It divides the body into left and right. The transverse plane or axial plane (horizontal) divides the body into cranial and caudal (head and tail) portions. What is […]

What are the two most common isotopes of arsenic? The most common is metallic gray, followed by yellow and then black. Gray arsenic, the only form used in industry, is the most stable of the three and the strongest conductor of electricity. How many 4p electrons are in arsenic? After the 3d sublevel is filled, […]

How can a picture make you feel? Sometimes an image carries a certain mood, sometimes it is overtly emotional. For example, an image of the sky on a stormy day may feel moody, or create a sense of anticipation, as if something is about to happen. But it might not be emotional in a particularly […]

How do you find the ratio of Class 9 in Mass? How to Calculate Mass Ratio Step 2: Determine the Mass of Each Individual Element Present. In this step, you multiply the number of atoms in one molecule of the compound by the molar masses you collected in Step 1. Step 3: Determine the Molar […]

What formula is y mX B? The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses […]

What happens to energy in a pendulum? Once the weighted end of the pendulum is released, it will become active as gravity pulls it downward. Potential energy is converted to kinetic energy, which is the energy exerted by a moving object. An active pendulum has the most kinetic energy at the lowest point of its […]

Why does it sound weird when you cover your ears? The short answer: “shadowing out” of high frequencies and passive resonance. We notice changes in noise level and/or frequency. This is why you can “hear the ocean” through a seashell: you only notice “sound” when it changes as the shell is put near your ear. […]
