Why is there no refraction at 90 degrees? When the refraction of light occurs, the incident light rays bend. If the incident light ray is incident at 900 degrees, this means that it is parallel to the normal and it cannot bend away or towards it. If the light ray doesn’t bend then refraction doesn’t […]
Will we ever be able to travel faster than light?
Will we ever be able to travel faster than light? Albert Einstein’s special theory of relativity famously dictates that no known object can travel faster than the speed of light in vacuum, which is 299,792 km/s. This speed limit makes it unlikely that humans will ever be able to send spacecraft to explore beyond our […]
What happens when a hot body and cold body are kept in contact with each other?
What happens when a hot body and cold body are kept in contact with each other? Thermal energy is moved from hot spots to cold spots by convection. Convection happens when hotter territories of a fluid or gas ascend to cooler regions in the fluid or gas. Cooler fluid or gas at that point replaces […]
What are the 4 methods of heat loss?
What are the 4 methods of heat loss? The body loses heat through: Evaporation of water from your skin if it is wet (sweating). Radiation (similar to heat leaving a woodstove). Conduction (such as heat loss from sleeping on the cold ground). Convection (similar to sitting in front of a fan or having the wind […]
What can you determine when searching ahead of you?
What can you determine when searching ahead of you? Scanning helps you to see problems ahead that may cause you to change speed or roadway position, such as vehicles and people that may be in the roadway or signs warning of problems ahead. Look ahead –In order to avoid emergency braking or steering, you should […]
How much energy does a geothermal heat pump use?
How much energy does a geothermal heat pump use? Geothermal heat pumps don’t generate heat — they just transfer it from the ground into your home. For every 1 unit of energy used to power your geothermal system, on average 4 units of heat energy are supplied. How much land do you need for geothermal […]

What are the 5 components of soil? 1 Answer. The major components of the Earth are water, air/gases, minerals, organic and biological components, microorganisms and gases. What are the three main characteristics of soil? The particles that make up soil are categorized into three groups by size – sand, silt, and clay. Sand particles are […]
What is the first thing that takes place in the condenser?
What is the first thing that takes place in the condenser? The superheat must be removed first before the refrigerant can condense. This occurs in the first portion of the condenser known as the desuperheating section. What is the primary and secondary purpose of the condenser? 2. What is the purpose of the condenser in […]
