Does radiation travel at the speed of light? Electromagnetic radiation is a type of energy that is commonly known as light. Generally speaking, we say that light travels in waves, and all electromagnetic radiation travels at the same speed which is about 3.0 * 108 meters per second through a vacuum. How long would it […]
How does a motor operate?
How does a motor operate? Electric motors work by converting electrical energy to mechanical energy in order to create motion. Force is generated within the motor through the interaction between a magnetic field and winding alternating (AC) or direct (DC) current. How do I select a motor for an application? 5 steps to choose the […]
What is the rejection region for the hypothesis test?
What is the rejection region for the hypothesis test? The rejection region is the interval, measured in the sampling distribution of the statistic under study, that leads to rejection of the null hypothesis H 0 in a hypothesis test. What is a critical value in statistics? A critical value is a line on a graph […]
Which is the most efficient cycle?
Which is the most efficient cycle? Carnot Cycle Which engine is most efficient? Wärtsilä 31SG At what RPM is an engine most efficient? In general, the economical band for petrol vehicles is between 1,500 and 2,500 rpm (for diesels it is between 1,300 rpm and 2,000 rpm), and these bands are the same for the […]
Is chloride negative or positive?
Is chloride negative or positive? Again, it is more energy-efficient for chlorine to gain one electron than to lose seven. Therefore, it tends to gain an electron to create an ion with 17 protons, 17 neutrons, and 18 electrons, giving it a net negative (–1) charge. It is now referred to as a chloride ion. […]
Does constant velocity mean no acceleration?
Does constant velocity mean no acceleration? If an object is changing its velocity -whether by a constant amount or a varying amount – then it is an accelerating object. And an object with a constant velocity is not accelerating. Is there work with constant velocity? When an object is moving with constant velocity, it means […]
How can we identify sedimentary rocks?
How can we identify sedimentary rocks? If the sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock. Clastic sedimentary rocks may have particles ranging in size from microscopic clay to huge boulders. Their names are based on their clast or grain size. The smallest grains are called clay, then silt, then sand. […]
What is the most difficult part of research?
What is the most difficult part of research? Introduction What are the most problem of the students in writing research? The study explored various and common challenges/difficulties during writing the research proposals and projects such as: difficulty in deciding the topic for research, lack of good knowledge of the methodology, inability of finding modern, specialized […]
How many proteins are in the body?
How many proteins are in the body? In humans, up to ten different proteins can be traced to a single gene. Proteome: It is now estimated that the human body contains between 80,000 and 400,000 proteins. However, they aren’t all produced by all the body’s cells at any given time. Cells have different proteomes depending […]
