What is gamma spectroscopy used for? Gamma-ray (γ-ray) spectroscopy is a quick and nondestructive analytical technique that can be used to identify various radioactive isotopes in a sample. In gamma-ray spectroscopy, the energy of incident gamma-rays is measured by a detector. How do we measure gamma rays? Scientists can use gamma rays to determine the […]
Is the parking brake a separate braking system?
Is the parking brake a separate braking system? A parking brake controls the rear brakes and is a completely separate device from your vehicle’s regular hydraulic brakes. It is in charge of keeping a parked vehicle stationary; it will prevent the car from rolling down a hill or moving. Which wheel does the parking brake […]
Under what condition concave lens form a real image?
Under what condition concave lens form a real image? Real images can be produced by concave mirrors and converging lenses, only if the object is placed further away from the mirror/lens than the focal point, and this real image is inverted. What does a concave lens do to an image? A lens refracts light and […]

Is a cookie sheet an insulator?
Is a cookie sheet an insulator? It stops the flow of energy from moving through the material. Many objects that are meant for holding hot objects (soup containers, handles of pots and pans) are made out of heat insulators so that the heat will not transfer through the area it touches. For example, Ted is […]

Is water chemical energy?
Is water chemical energy? Water, like many substances, contains two kinds of energy. The first kind of energy is called kinetic energy. This is energy that is used during the execution of processes, such as movement. Because of kinetic energy water can flow and waves can exist. What form is energy stored in the human […]
What is a potential failure mode?
What is a potential failure mode? Definition: Potential failure mode is defined as the manner in which the process could potentially fail to meet the process requirements and/or design intent as decribed in the process function/requirements column. ( What are the three usual causes of failure? The usual causes of material failure are incorrect materials […]
