What is the best angle for air to glass transition? 56.31° Can the Brewster’s angle occur at the interface from air to glass? The Brewster’s angle can occur at the air/glass interface because there are infinite ways that the incidentand refractive angle will add up to 90°. What will be the Brewster angle for a […]
What is the purpose of volume displacement?
What is the purpose of volume displacement? The displacement method (submersion, or dunking method) can be used to accurately measure the volume of the human body and other oddly shaped objects by measuring the volume of fluid displaced when the object is submerged, as illustrated in the figure below. What is my height app? GHeight […]
How does volume affect buoyancy?
How does volume affect buoyancy? Buoyancy is created when the contained volume of a certain material (gas or liquid) that is lighter and placed into a heavier surrounding material either gas or liquid. So if the volume of the buoyant (lighter) object is increased then the buoyancy will also increase. How do you calculate buoyancy […]
Is a proportioning valve necessary with 4 wheel disc brakes?
Is a proportioning valve necessary with 4 wheel disc brakes? If I add disc brakes will I need a proportioning valve? Yes. Without it your braking system will not operate properly. Do you have to have a brake proportioning valve? A Proportioning valve is required on vehicles that have disc brakes on the front wheels […]
Is it safe to spray perfume on skin?
Is it safe to spray perfume on skin? How can perfume negatively affect your skin? “Sprayed directly onto skin, perfume is so aggressive that it undermines skin’s ability to protect itself against UV damage. That means that perfume-covered skin becomes more vulnerable to sun damage and ageing pigmentation.” Is it bad to drink perfume? Most […]
What is the most common act of terrorism?
What is the most common act of terrorism? Shooting was the most typical type of terrorist attack in 2019. That year, shootings were used in 41 percent of terrorist attacks. With 15 percent of all attacks, planting mines and IEDs (bombs) was the second most common act of terrorism that year. Why is it so […]
Why does refrigerant absorb heat?
Why does refrigerant absorb heat? The refrigerant leaves the expansion valve at low pressure and temperature then heads straight into the evaporator. The temperature of the room air is higher than the temperature of the cool refrigerant this allows it to absorb more energy and boil the refrigerant completely into a vapour. What carries the […]
Does a hypothesis turn into a theory?
Does a hypothesis turn into a theory? A hypothesis is not a prediction. A theory is not necessarily a well-supported explanation. A (causal) hypothesis does not become a theory if it subsequently becomes well-supported by evidence. How is a theory proven? A scientific theory is a description of the natural world that scientists have proven […]
