How does the eye respond to bright light? In bright light, it contracts. Light detected by the retina of your eye is converted to nerve impulses that travel down the optic nerve. Some of these nerve impulses go from the optic nerve to the muscles that control the size of the pupil. More light creates […]
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 […]
Which object experiences the greatest acceleration?
Which object experiences the greatest acceleration? Car A Which vehicle experiences the greater change in acceleration? (c) Mass and acceleration are inversely proportional to each other. Therefore, car experiences greater acceleration due to its smaller mass. (d) Due to its smaller mass or opposition to the force exerted on it, the car is likely to […]
What is the wavelength of light that has a frequency of 6 x 10 14 Hz?
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? […]
What is a normal Haemoglobin level?
What is a normal Haemoglobin level? The normal range for hemoglobin is: For men, 13.5 to 17.5 grams per deciliter. For women, 12.0 to 15.5 grams per deciliter. What are the factors which enable the binding of oxygen to Haemoglobin? Several factors influence the binding of oxygen to hemoglobin: temperature, pH, PCO2 and 2,3 diphosphoglycerate […]
Which is the SI unit?
Which is the SI unit? There are seven basic units in the SI system: the meter (m), the kilogram (kg), the second (s), the kelvin (K), the ampere (A), the mole (mol), and the candela (cd). What is dimension formula? Dimensional formula (equation) (Definition) : An equation, which gives the relation between fundamental units and […]
How do I present a large amount of data in Excel?

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 […]
