What type of energy is in a log? chemical energy What form of energy is possessed by charcoal before it is burned? Potential energy Chemical energy is energy stored in the bonds of atoms and molecules. Batteries, biomass, petroleum, natural gas, and coal are examples of chemical energy. Chemical energy is converted to thermal energy […]
Does hanging from a bar make you taller?
Does hanging from a bar make you taller? While there is no dearth of physical activities which may help your child to grow taller, hanging from pull-up bars has certainly been the most recommended one. Making use of hanging bars is not only enjoyable for the kids but it also helps them maintain a good […]
What is the unit of root mean square velocity?
What funnels sound waves from outside the ear toward the middle ear?
What funnels sound waves from outside the ear toward the middle ear? The purpose of the pinna is to catch sound waves, amplify them slightly, and funnel them down the ear canal to the tympanic membrane (eardrum) [3]. The tympanic membrane is a very thin structure that separates the outer ear canal from the middle […]
What are normal and anomalous Zeeman effect?
What are normal and anomalous Zeeman effect? The normal Zeeman effect occurs when there is no spin magnetic moment – states with zero spin are necessary. In singulett systems the spins of the electrons cancel each other i.e. add up to zero. This is called anomalous Zeeman Effect and can be observed in atomic transitions […]
What is the formula of constant speed?
What is the formula of constant speed? Formula for constant-speed = Total distance / Total time taken. How do I calculate percentage of a total? To find the percentage of the marks, divide the marks obtained in the examination with the maximum marks and multiply the result with 100. Example 1: If 1156 is the […]
How do we use microwaves in everyday life?
How do we use microwaves in everyday life? Microwaves are widely used in modern technology, for example in point-to-point communication links, wireless networks, microwave radio relay networks, radar, satellite and spacecraft communication, medical diathermy and cancer treatment, remote sensing, radio astronomy, particle accelerators, spectroscopy, industrial … What are microwaves explain their properties? Properties of Microwaves […]
Should you explain in classical mechanics a moving body with constant speed has no force?
Should you explain in classical mechanics a moving body with constant speed has no force? From classical mechanics, we know that the force is the rate of change of momentum, one of it’s simplest forms is F=ma, so if a body moves with constant velocity, then its acceleration is zero, and by the previous definition […]
What causes change to ecosystems?
What causes change to ecosystems? Important direct drivers include habitat change, climate change, invasive species, overexploitation, and pollution. Most of the direct drivers of degradation in ecosystems and biodiversity currently remain constant or are growing in intensity in most ecosystems (see Figure 4.3). Do ecosystems change little over time? Ecosystems, the interactive system of living […]
