By 1900 around 85 per cent of the Russian people lived in the countryside and earned their living from agriculture. The nobility still owned the best land and the vast majority of peasants lived in extreme poverty. Why was there a […]
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 […]
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 […]
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 […]
What 3 components make up most magmas?
What 3 components make up most magmas? Magmas can vary widely in composition, but in general they are made up of only eight elements; in order of importance: oxygen, silicon, aluminum, iron, calcium, sodium, magnesium, and potassium (Figure 3.6). Which component of magma is the highest in value? Felsic magma has the highest silica content […]
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 […]
What are the main factors that affect density altitude?
What are the main factors that affect density altitude? There are three important factors that contribute to high density altitude: Altitude. The higher the altitude, the less dense the air. Temperature. The warmer the air, the less dense it is. Humidity. 80 oF. 90 oF. 100 oF. 110 oF. 120 oF. How does the temperature […]

What does the placenta sound like on a Doppler?
What does the placenta sound like on a Doppler? Whenever you use a doppler, you’ll hear a variety of sounds depending on where it’s placed. A “whooshing” sound usually indicates either placenta or movement. Some people also describe the noise as similar to that of blowing trees. This should not be mistaken for a baby’s […]
How can I measure 5G radiation?
How can I measure 5G radiation? Electromagnetic Field (EMF) meters are used to measure RF radiation. With 5G deployments are growing worldwide, the obvious question is – which EMF meters are best suited for measuring 5G signals? Our recommendation for the best EMF meter is the TriField EMF Meter. What is the best radiation detector […]
