How do they measure weight in England? Weight measurements in the UK, US, Australia and New Zealand In the US, they use pounds (lbs) for their weight while Australia and New Zealand use kilograms. So, a man weighing 90kg would give his weight as 198 lbs in the US and just over 14 stone in […]
What are the derived units of density?
What are the derived units of density? Thus density is an intensive quantity. The SI derived unit for density is the kilogram per cubic meter (kg/m3). This unit is awkwardly large for most chemical applications. The unit g/cm3 and its equivalent, g/mL, are more commonly used for solid and liquid densities. Which one is derived […]
Is magnetic field inside a toroid zero?
Is magnetic field inside a toroid zero? The magnetic field lines inside the toroid are concentric circles. The magnetic field is homogeneous inside the toroid and zero outside the toroid. We asses the direction of the magnetic B-field by the right-hand rule. Why is there no magnetic field outside a toroid? After applying Ampere’s Law, […]
What happens to the speed of a body when a force is applied?
Why is electricity so cheap in Iceland?
Why is electricity so cheap in Iceland? This is one of the plants that enables Iceland to produce 100 per cent of its grid electricity from renewable sources. It’s all either geothermal or hydro. Electricity prices are low in Iceland, especially for the aluminum smelting industry. Can you drink the water in Iceland? Yes, it […]
Is it safe to breathe in ozone?
Is it safe to breathe in ozone? When inhaled, ozone can damage the lungs. Relatively low amounts can cause chest pain, coughing, shortness of breath and throat irritation. Ozone may also worsen chronic respiratory diseases such as asthma and compromise the ability of the body to fight respiratory infections. Can ozone cure Lyme disease? Ozone […]
What kind of energy is a glowing firefly?
What kind of energy is a glowing firefly? This type of light production is called bioluminescence. The method by which fireflies produce light is perhaps the best known example of bioluminescence. When oxygen combines with calcium, adenosine triphosphate (ATP) and the chemical luciferin in the presence of luciferase, a bioluminescent enzyme, light is produced. What […]
What are the 5 wave properties of light?
What are the 5 wave properties of light? You will investigate the wave properties of light: reflection, refraction, diffraction and interference. The light source is a helium-neon laser. Why Study Light? Physics is described as the study of matter and radiation. Is wave a property of light? Light has the properties of waves. Like ocean […]
What connects the pancreas to the liver?
What connects the pancreas to the liver? Insulin controls the amount of sugar in the blood. As pancreatic juices are made, they flow into the main pancreatic duct. This duct joins the common bile duct, which connects the pancreas to the liver and the gallbladder. What is the main sign of pancreatitis? Acute pancreatitis signs […]
