What is the best definition of reflection? 1 : an instance of reflecting especially : the return of light or sound waves from a surface. 2 : the production of an image by or as if by a mirror. 3a : the action of bending or folding back. b : a reflected part : fold. […]

Why is it illegal to take pebbles from the beach? You can not legally take sand from the beach as you would be contributing (even if only in a small way) towards the weakening of the defensive barrier the beach provides from the sea to the land. Sand is off-limits though. Why are the beaches […]

What type of light is needed to cause the photoelectric effect? ultraviolet light What is the smallest quantum of light called? photons Why is the mass of a photon zero? But according to special relativity, light ALWAYS travels with the light speed c, and is NEVER at rest. And so it has zero REST mass. […]

How do you find the missing resistance? If you know the circuit’s total current and voltage, you can use Ohm’s Law R = V/I to find the total resistance, then the formula for resistors in parallel to solve for the missing resistor value. What happens when resistors are connected in parallel? When resistors are connected […]

What are the 5 types of cleavage? Types of cleavage Determinate. Indeterminate. Holoblastic. Meroblastic. How does mineral break apart in an irregular way? Fracture describes how a mineral looks when it breaks apart in an irregular way. Why do you think some minerals are easier to identify than others? 4. Why do you think some […]

What is wave erosion quizlet? Waves erode the land by abrasion and “deposition” true. In the process called “longshore drift”, beach sediment gets moved down a beach with the current. true. Waves change direction as they appproach shore because they begin to “drag” What are two results of wave erosion along a coast quizlet? What […]

Where is energy stored in plants? Hi, Plants store their energy in the form of starch, which is a complex carbohydrate that can be broken down into a simple carbohydrate (glucose) for the plant to use for energy. Plant cells store starch in storage organelles like all cells do. How is energy stored and released […]
