Why is static friction higher than kinetic friction? Static friction is greater than kinetic friction because there are more forces at work keeping an object stationary than there are forces working to resist an object once it is in motion. What is the formula of static friction? The maximum static friction force is: (fs)max = […]
What is the difference between two consecutive nodes?
What is the difference between two consecutive nodes? Hence we can say that the phase difference between the particles vibrating between two consecutive nodes is zero. What is the least distance between two consecutive nodes? In a stationary wave, the distance between two successive nodes(anti-nodes) is one half wavelength. Therefore, the distance between a node […]
What is infrared frequency?
What is infrared frequency? Infrared radiation (IR radiation for short) describes electromagnetic waves in the spectral range between visible red light and longer-wave microwave radiation (also known as terahertz radiation). Infrared (IR) has wavelengths λ between 780 nm and 1 mm, which corresponds to a frequency range from 300 GHz to 400 THz. What blocks […]
What is the standard interval between contour lines on a map?
What is the standard interval between contour lines on a map? Individual contour lines on a topographical map are a fixed interval of elevation apart known as a contour interval. Common contour intervals are 5, 10, 20, 40, 80, or 100 feet. Why do contour lines never cross? Contour lines never cross on a topographic […]

Can you levitate a person with magnets?
Can you levitate a person with magnets? Normal things, even humans, can levitate if they are placed in a strong magnetic field. Such materials can be levitated using magnetic fields of about 10 Tesla. Can you fly with magnets? So the short answer is that a magnetized material is considered a hazardous material and is […]

Which categories of goods are rival in consumption? There are four types of goods based on the characteristics of rival in consumption and […]
What are the energy demands of soccer?
What are the energy demands of soccer? Aerobic energy production appears to account for more than 90% of total energy consumption. Nevertheless, anaerobic energy production plays an essential role during soccer matches. During intensive exercise periods of a game, creatine phosphate, and to a lesser extent the stored adenosine triphosphate, are utilized. What qualities do […]
