What is the coefficient of static friction? The coefficient of static friction is the ratio of the maximum static friction force (F) between the surfaces in contact before movement commences to the normal (N) force. How do you find the minimum coefficient of static friction? To find the minimum coefficient of static friction between two […]

Does energy have momentum?
Does energy have momentum? Light indeed carries energy via its momentum despite having no mass. Public Domain Image, source: Christopher S. Baird. In the above equation, E is the total energy of the particle, p is the momentum of the particle (which is related to its motion), c is the speed of light, and m […]
What are the main problems in Tokyo?
What are the main problems in Tokyo? The main issue is overpopulation however, the impact of the overpopulation are the issues that Tokyo is facing. Nevertheless, population density is not something that is easily controllable, which leads to the issues that these densely populated cities face such as water supply and housing shortages. What is […]
Can tsunamis be stopped?
Can tsunamis be stopped? Tsunamis could be stopped before they hit the coastline, a Welsh mathematician has proposed in a study of deep-ocean sound waves. Dr Usama Kadri, from Cardiff University’s School of Mathematics, has suggested that firing deep-ocean sound waves at an oncoming tsunami could save lives and reduce on-shore damage. What disaster will […]
Are combustion engines more efficient?
Are combustion engines more efficient? How efficient are engines? Combustion engines are stupefyingly inefficient. Most diesel engines do not even have a thermal efficiency of 50%. Of every gallon of diesel burned by a combustion engine, less than half of the energy generated becomes mechanical energy. How long will internal combustion engines be around? The […]
