Can superposition theorem be applied to a circuit containing one AC and one DC source? Another limitation of these methods is that the sources must all be of the same current type: ac or dc. The superposition theorem does not have this limitation, which makes it a valuable technique in electronic circuit design. The superposition […]
What are the defects that can be identified by NDT techniques?
What are the defects that can be identified by NDT techniques? This method allows for the detection of corrosion, misalignment, damage, cracks, and more. Visual testing is inherent in most other types of NDT as they will generally require an operator to look for defects. What is defect in NDT? Generally a defect can be […]
Why are STEM subjects important?
Why are STEM subjects important? STEM stands for science, technology, engineering, and mathematics. STEM is important because it pervades every part of our lives. STEM activities provide hands-on and minds-on lessons for the student. Making math and science both fun and interesting helps the student to do much more than just learn. Why is STEM […]
Where does a star get its energy?
Where does a star get its energy? Many stars produce much more energy than the Sun. The energy source for all stars is nuclear fusion. Stars are made mostly of hydrogen and helium, which are packed so densely in a star that in the star’s center the pressure is great enough to initiate nuclear fusion […]
What are the principles of stoichiometry?
What are the principles of stoichiometry? The principles of stoichiometry are based upon the law of conservation of mass. Matter can neither be created nor destroyed, so the mass of every element present in the product(s) of a chemical reaction must be equal to the mass of each and every element present in the reactant(s). […]
How do you start writing a hypothesis?
How do you start writing a hypothesis? Developing a hypothesis Ask a question. Writing a hypothesis begins with a research question that you want to answer. Do some preliminary research. Formulate your hypothesis. Refine your hypothesis. Phrase your hypothesis in three ways. Write a null hypothesis. What is a good sentence for hypothesis? Their hypothesis […]
Can locusts kill you?
Can locusts kill you? Can locusts hurt humans? Locusts do not attack people or animals. There is no evidence that suggests that locusts carry diseases that could harm humans. Is locust attack a biological disaster? The Ministry of Home Affairs has now identified locust attacks as a natural disaster and has directed states to undertake […]
Do you pinch skin for IM injection?
Do you pinch skin for IM injection? Insert needle at an 45o angle to the skin. Pinch up on SQ tissue to prevent injecting into muscle. Aspiration before injection is not required. What size needle is used for a subcutaneous injection? 5/8″ needle What are the 3 types of injections? The three main types of […]
What are the sensory receptors?
What are the sensory receptors? Sensory receptors are dendrites of sensory neurons specialized for receiving specific kinds of stimuli. Sense organs (such as the eyes and ears) consist of sensory neurons with receptors for the special senses (vision, hearing, smell, taste, and equilibrium) together with connective, epithelial, or other tissues. What are the 6 sensory […]
What are the red flags of identity theft?
What are the red flags of identity theft? Red Flags are suspicious patterns or practices, or specific activities that indicate the possibility of identity theft. For example, if a customer has to provide some form of identification to open an account with your company, an ID that doesn’t look genuine is a “red flag” for […]
