What is entropy in engineering? Entropy (S) is a property of a substance, as are pressure, temperature, volume, and enthalpy. Because entropy is a property, changes in it can be determined by knowing the initial and final conditions of a substance. Entropy quantifies the energy of a substance that is no longer available to perform […]
What is the difference between a latch and a flip flop?
What is the difference between a latch and a flip flop? Both latches and flip-flops are circuit elements whose output depends not only on the current inputs, but also on previous inputs and outputs. The difference between a latch and a flip-flop is that a latch does not have a clock signal, whereas a flip-flop […]
What is a break line on a blueprint?
What is the maximum displacement in a transverse wave?
What is the maximum displacement in a transverse wave? 2- A Crest is the maximum upwards displacement in a Transverse wave. 3- One complete wave cycle is referred to as a Wavelength . What is the maximum displacement of a wave? Amplitude, in physics, the maximum displacement or distance moved by a point on a […]
Which of the following heat disorders is least severe?
Which of the following heat disorders is least severe? Heat cramps are the mildest form of heat illness. These are painful muscle cramps and spasms that occur during or after intense exercise and sweating in high heat. When a person’s temperature reaches 104 F the chances of survival are decreased dramatically? When a person’s temperature […]
Is it possible to create a machine that runs forever?
Is it possible to create a machine that runs forever? Perpetual motion is the motion of bodies that continues forever in an unperturbed system. A perpetual motion machine is a hypothetical machine that can do work infinitely without an external energy source. This kind of machine is impossible, as it would violate the first or […]
Do front wheel drive cars have a rear axle?
Do front wheel drive cars have a rear axle? FWD cars dont have a rear axle, the wheels are mounted independently, there may be some situations where there is a tube there, but it will not have an axle shaft. The wheels just ride independently on bearings, they aren’t connected by an axle like in […]
What makes safety glasses safe?
What makes safety glasses safe? That’s where safety glasses come in! When working (or playing) in situations that pose a risk to your eyes, safety glasses are your best bet. Unlike regular glasses, they’re designed to conform to a higher standard of impact resistance. Most safety glasses are made from polycarbonate, a lightweight but strong […]
What does Second Law of Thermodynamics tells about the entropy of spontaneous processes and processes at equilibrium?
What does Second Law of Thermodynamics tells about the entropy of spontaneous processes and processes at equilibrium? The second law of thermodynamics states that a spontaneous process increases the entropy of the universe, Suniv>0. If ΔSuniv<0, the process is nonspontaneous, and if ΔSuniv=0, the system is at equilibrium. How is entropy related to the second […]
