The clitellum is a thickened, saddle-like girdle that encircles the worm just behind its head. It is composed of modified skin cells and secretes a sticky fluid that helps the worm to move. The clitellum also helps to protect the worm’s...
There are two types of strokes in an internal combustion engine: compression and exhaust. Both strokes have different purposes and occur in different parts of the engine cycle. The compression stroke is when the piston moves up the cylinder and compresses...
The slope of a velocity-time graph is the measure of the rate of change of velocity with respect to time. It is a vector quantity and is represented by the symbol ‘s’. The SI unit of slope is meter per second....
There are approximately 4.0 moles of water molecules in 1 liter of water. This means that there are approximately 4.0 moles of water molecules in 4.0 liters of water. This is a very large number of molecules and it is difficult...
The slope intercept equation of the line below is y=4x+2. The line passes through the points (0,2) and (1,6). To find the equation, we first need to find the slope. The slope is the rise over the run, or in this...
There are many different types of engineering degrees available, so it can be difficult to decide which one is best for the future. However, there are a few factors to consider that can help make the decision easier. The first factor...
One mole of carbon dioxide (CO2) contains one mole of carbon and two moles of oxygen. In other words, out of a sample of one mole of CO2, one mole of carbon and two moles of oxygen atoms are present. The...
The main difference between an associate’s degree and bachelor’s degree is the time it takes to complete each program. An associate’s degree usually takes two years to complete, while a bachelor’s degree typically takes four years. The other main difference is...
