Why is the work output of a machine always less than the work input?
Why is the work output of a machine always less than the work input? Although nearly equal, the output work is less than the input work because of friction. All machines use some amount of input work to overcome friction. The only way to increase the work output is to increase the amount of work […]

What is the important of fuse?
What is the important of fuse? A fuse(s) is needed in any electrical system (AC or DC). These protection devices react to the amount of heat being produced by electricity passing through wires and/or components. They are used so as to protect wires and components from the extreme heat produced should there be an electrical […]

Scientists, on the other hand, describe sounds with characteristics that can be measured using instruments. How do you describe a beautiful sound? If you hear […]
What happens when a fluid cools down?
What happens when a fluid cools down? Answer: When the fluid cools, the kinetic energy of the molecules decreases. This causes the molecules to slow down and move closer together. Since the molecules are closer together, the density of the fluid increases and the fluid sinks. What best describes how fluids change as they travel? […]

Why did Ebbinghaus use nonsense syllables?
Why did Ebbinghaus use nonsense syllables? Ebbinghaus had one experimental subject: himself. Nonsense syllables were stimuli Ebbinghaus had never seen before. He wanted to study memory for things being learned for the first time, so nonsense syllables seemed to meet his needs. Why did Ebbinghaus study memory for nonsense syllables quizlet? Why did Hermann Ebbinghaus […]
What statement summarizes the difference between a law and a theory?
What statement summarizes the difference between a law and a theory? Which statement summarizes the difference between a law and a theory? A law describes natural phenomena, but a theory explains why those phenomena occur. The data from one particular experiment do not agree with a current theory. What is the best reason for the […]
