Is selective coordination required? Selective coordination is required for systems related to life safety (as defined in the NEC), and is achieved when an overcurrent on a circuit is interrupted and only the closest upstream device opens such that only the section of the electrical system with a problem is taken offline. What is selective […]
Why there is a need for scientific knowledge in education?
Why there is a need for scientific knowledge in education? Problem-solving and critical thinking are two of the most important skills students learn in school. In this way, science is one of the most important subjects students study, because it gives them the critical thinking skills they need in every subject. What is the impact […]
What is the treatment when cell division goes wrong?
What is the treatment when cell division goes wrong? Medicines that are used to treat cancer are sometimes aimed at killing cells that are rapidly dividing by mitosis. They inhibit the synthesis or function of DNA – this type of treatment is called chemotherapy. What will happen if mitosis go wrong? If the process of […]
What are the advantage of rotation magnetic field?
What are the advantage of rotation magnetic field? The advantages of rotating field system are given below. The DC excitation voltage is low and it is very easy to insulate. This intern reduces the size of the machine. c. Out put current can be taken directly from the fixed terminals on the stator. How can […]
Do electrons know they being observed?
Do electrons know they being observed? This process is sometimes referred to as decoherence. We also see phrases such as “wavefunction collapse”. By virtue of such an interaction of a quantum system with a classical measurement device, one could quite misleadingly assert that the electron “knows” it is being observed. It doesn’t. Why do wave […]
What prevents the wrong gas from being connected to the equipment?
What prevents the wrong gas from being connected to the equipment? The connection is marked with a Compressed Gas Association (CGA) number and will be left-hand or right-hand threaded to match the nut or fitting. This prevents a piece of incompatible gas equipment from being connected to the wrong gas supply. Can gas cylinders explode? […]

What are protective strategies?
What are protective strategies? Protective behaviour strategies. Help the child identify who they can talk to if they don’t feel safe. Make sure the child knows what to do if they are in an unsafe situation. Kids should have their own safe place in the house – a place that is ‘theirs,’ where they can […]
Are multiple choice tests accurate?
Are multiple choice tests accurate? Multiple choice test questions, also known as items, can be an effective and efficient way to assess learning outcomes. Multiple choice test items are less susceptible to guessing than true/false questions, making them a more reliable means of assessment. When should I use multiple choice test? Multiple-choice items are best […]
How do you find the internal diameter?
How do you find the internal diameter? Calculating the internal diameter depends on the outside diameter and the thickness of the outer circle. Find the total diameter of the object in question by taking a measurement from the outside wall of one side (the point of origination) straight across to the outside wall of the […]
