How do you diagnose a bad brake master cylinder? If the fluid is leaking past the seals inside the cylinder, the pedal may feel firm for a moment but won’t hold steady; it’ll feel spongy and keep sinking towards the floor. When a master cylinder begins to fail, sometimes the brakes will feel fine one […]
What is a photovoltaic effect in a solar cell?
What is a photovoltaic effect in a solar cell? The photovoltaic effect is a process that generates voltage or electric current in a photovoltaic cell when it is exposed to sunlight. It is this effect that makes solar panels useful, as it is how the cells within the panel convert sunlight to electrical energy. How […]
Does Weight Affect coefficient of friction?
Does Weight Affect coefficient of friction? Also, the coefficient of friction doesn’t depend on the mass of the object. Does angle affect force? As the angle is increased, the acceleration of the object is increased. The explanation of this relates to the components that we have been drawing. As the angle increases, the component of […]
What energy transformation occurs when you eat food?
What energy transformation occurs when you eat food? “When people consume food, the body utilizes the chemical energy in the bonds of the food and transforms it into mechanical energy, a new form of chemical energy, or thermal energy” (What Is Energy Transformation?, 2014, par. Which statement describes the energy transformation that occurs when a […]
How does crystallinity affect polymer properties?
How does crystallinity affect polymer properties? Crystallinity: The crystallinity of the polymer increases strength, because in the crystalline phase, the intermolecular bonding is more significant. Hence, the polymer deformation can result in the higher strength leading to oriented chains. How does molecular weight affect crystallinity? Narrow molecular weight, linear polymer chains, and high molecular weight […]
How do you know if a liquid is Newtonian?
How do you know if a liquid is Newtonian? A classic Newtonian fluid is water. Water has a very predictable viscosity and will always flow predictably regardless of the forces acting on it. Newtonian fluids also have predictable viscosity changes in response to temperature and pressure changes. What is Newtonian and non-Newtonian fluids? Newtonian liquids […]
What is the coefficient of friction between the crate and the floor?
What is the coefficient of friction between the crate and the floor? Static and Kinetic Friction The coefficient of static friction between the crate and floor is 0.700 and the coefficient of kinetic friction is 0.600. Is rubber a grippy? Rubber is grippy due to the massive amount of friction that occurs between objects. What […]
When two or more atomic nuclei join or fuse together?
When two or more atomic nuclei join or fuse together? Nuclear fusion is the process by which two atomic nuclei combine to form a single atomic nucleus. If the two nuclei that go into a fusion reaction have an atomic number below 26 (the atomic number of iron), the nuclear reaction can release energy. Atomic […]
What does an accelerometer measure?
What does an accelerometer measure? An accelerometer is a sensor that measures the dynamic acceleration of a physical device as a voltage. What are vibration sensors? A vibration sensor is a device that measures the amount and frequency of vibration in a given system, machine, or piece of equipment. Those measurements can be used to […]
How often should the extension cord insulation plug and connector be inspected for damage?
How often should the extension cord insulation plug and connector be inspected for damage? Each cord set, attachment cap, plug and receptacle of cord sets, and any equipment connected by cord and plug, except cord sets and receptacles which are fixed and not exposed to damage, shall be visually inspected before each day’s use for […]
