What is the difference between renewable and nonrenewable energy source? Nonrenewable energy resources, like coal, nuclear, oil, and natural gas, are available in limited supplies. This is usually due to the long time it takes for them to be replenished. Renewable resources are replenished naturally and over relatively short periods of time. What are renewable […]
Can you filter oil out of water?
Can you filter oil out of water? Researchers have developed a special filter coating that essentially can strain oil out of water. It works by repelling oil, but attracting water, which are unconventional properties for a material to have. What happens when you mix oil and water detergent? Detergent grabs onto both types of molecules […]
What are the 5 phases of a project?
What are the 5 phases of a project? Developed by the Project Management Institute (PMI), the five phases of project management include conception and initiation, planning, execution, performance/monitoring, and project close. How can you identify a phase in a project? The Project Management Institute (PMI) identifies four major phases of a project as characteristics of […]
What are examples of chloroplast?
What are examples of chloroplast? The definition of a chloroplast is a part of a plant that has chlorophyll and conducts photosynthesis. An example of a chloroplast is a cell in algae that consumes carbon dioxide and releases oxygen while creating sugar. A plastid that contains chlorophyll and is found in the cells of green […]
What are 3 types of kinetic friction?
What are 3 types of kinetic friction? Summary Friction is the force that opposes motion between any surfaces that are in contact. There are four types of friction: static, sliding, rolling, and fluid friction. Static, sliding, and rolling friction occur between solid surfaces. Fluid friction occurs in fluids, which are liquids or gases. What causes […]
Why is static friction higher than kinetic friction?
Why is static friction higher than kinetic friction? Static friction is greater than kinetic friction because there are more forces at work keeping an object stationary than there are forces working to resist an object once it is in motion. What is the formula of static friction? The maximum static friction force is: (fs)max = […]
Are pilots in high demand?
Are pilots in high demand? Age-based retirement and fleet growth were, and are expected to remain, the main drivers of pilot demand.” CAE predicts the civil aviation industry will require a total of 484,000 pilots in 2029: an estimated 426,000 for airlines and another 58,000 business jet crews. Do airlines prefer military pilots? Airlines preferred […]
What is egg drop experiment?
What is egg drop experiment? The Classic “Egg-Drop” experiment has been a standard in science instruction for many years. Essentially, students are asked to construct some type of container that will keep a raw egg from cracking when dropped from ever-increasing elevations. What happens during an egg drop? While at rest, the egg has potential […]
What is the difference between two consecutive nodes?
What is the difference between two consecutive nodes? Hence we can say that the phase difference between the particles vibrating between two consecutive nodes is zero. What is the least distance between two consecutive nodes? In a stationary wave, the distance between two successive nodes(anti-nodes) is one half wavelength. Therefore, the distance between a node […]
What is infrared frequency?
What is infrared frequency? Infrared radiation (IR radiation for short) describes electromagnetic waves in the spectral range between visible red light and longer-wave microwave radiation (also known as terahertz radiation). Infrared (IR) has wavelengths λ between 780 nm and 1 mm, which corresponds to a frequency range from 300 GHz to 400 THz. What blocks […]
