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 renewable and nonrenewable energy source?
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 […]
How does a projectile launcher work?
How does a projectile launcher work? Launcher The Projectile Launcher is used to investigate important concepts in two- dimensional kinematics. A steel ball placed in the launch barrel can be projected for different launch velocities and launch angles. Upon setting the desired angle and range, the hand pump is then used to pressurize the system. […]
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 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 […]
Do criminal investigators get paid well?
Do criminal investigators get paid well? The median wage in 2020 for Detectives and Criminal Investigators in California was $104,428 annually, or $50.21 hourly. The median wage for Detectives and Criminal Investigators in Kings County was $82,271 annually, or $39.55 hourly. The median is the point at which half of the workers earn more and […]
Why does gravity not pull us through the floor?
Why does gravity not pull us through the floor? When two ordinary objects, such as your shoes and the floor on which you stand, come close enough together, the electrons that surround the atoms of the floor and of your shoes repel each other strongly through the electic force (the so-called Coulomb force). But, not […]
What is the standard interval between contour lines on a map?
What is the standard interval between contour lines on a map? Individual contour lines on a topographical map are a fixed interval of elevation apart known as a contour interval. Common contour intervals are 5, 10, 20, 40, 80, or 100 feet. Why do contour lines never cross? Contour lines never cross on a topographic […]
