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 […]
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 resolving power of a compound microscope?
What is the resolving power of a compound microscope? The resolving power is the capacity of an instrument to resolve two points that are close together. The resolving power of a compound microscope is 0.25μm. How do you increase the magnification of a compound microscope? In order to increase the magnifying power of a compound… […]
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. […]
