Why is it important to have a reference point? A reference point is important in determining motion because in order to say that something is moving, you need to have something stationary to compare it to. Is the cyclist accelerating How do you know? How do you know the cyclist is accelerating? a graph of […]

What happens when the retina detects light?
What happens when the retina detects light? When a photon reaches your eye it passes through the transparent cornea and then through the lens which refracts and focuses the light onto your retina, where the light is selectively detected and absorbed by special photoreceptor cells: the rods and cones. Why do doctors shine a light […]

What happens to plate A as it collides with plate B?
What happens to plate A as it collides with plate B? Answer: The volcanic arc is formed to “plate A” as it collides with “plate B”. The collision of these two plates results in the oceanic current which is generated. The earthquake is produced because of the volcanic arc creation between the plate A and […]

What is difference between peroxide and superoxide?
What is difference between peroxide and superoxide? The primary difference between a peroxide and a superoxide lies in the oxidation state of the oxygen atom. In a peroxide, the oxidation state of oxygen is known to be -1 whereas in a superoxide, the oxidation state of oxygen is known to be -1/2. What is phosphorus […]
