The speed of light in a certain type of glass is slower than the speed of light in air

the index of refraction for that type of plastic?

ith a constant speed of 0.800c relative to the Earth travels toward the star. How much time would elapse on a clock on board the spaceship? And how much time would elapse on a clock on the Earth?

how increasing the temperature directed to yeast, affects its speed of producing carbon dioxide during yeast fermentation. I have the variables and method all planned out but the thing is, i don't know how i'm going to relate this to biology terms and concepts. I do know that yeast is a simple eukaryotic cell and may functions like one. Besides that, I also know that the cell membrane of yeast may break when uv light is directed on it, but i can't really seem to find and relate other biology concepts. Teacher asked me whats my objective of doing this and how i'm going to discuss it, suddenly I just really don't know what to answer. I hope you can help me. Thank you so so much in advance.

ning wave speeds through different mediums and had come across a confusing question. Can you state the speed of light from fastest to slowest as it passes (or doesn't) through the following: Liquid, solid, gas, and a vacuum?

it is Reading Break I am doubtful that I can contact my teacher before I need to know how to solve this. The following is the question: A light shines from the top of a pole that is 20 meters high. A ball is falling 10 meters away from the pole, casting a shadow on a building that is 30 meters away. When the ball is 25 meters from the ground it is falling at a speed of 6 meters per second. How fast is the shadow moving? Side note: from left to right are the following, lamp, ball, wall with shadow.

working on it since Friday) As it is reading break I doubt that I can cnotact my teacher before it is due. The question is as following: A light shines from the top of a pole that is 20 meters high. A ball is falling 10 meters away from the pole, casting a shadow on a building that is 30 meters away. When the ball is 25 meters from the ground it is falling at a speed of 6 meters per second. How fast is the shadow moving? side note: from left to right it goes lamp, falling ball, wall with shadow.

.80 kN/m). The block is initially at rest at its equilibrium position when a force (magnitude P = 80 N) acting parallel to the surface is applied to the block, as shown. What is the speed of the block when it is 0.13 from its equilibrium position?

les. Draw a neat diagram and find the distance between the instants when the lighthouse 040° T and 120° T. HINT: This is NOT a problem to be solved using cosine rule. Since the distance is constant, the ship will travel along the arc. You should therefore use radian measure to workout the distance along the arc. Also remember that all bearings are from seawards . 2, The length of a shadow of a vertical flag mast 2.5 meters high is 5.2 meters (shadow's length). Find the sun's altitude. 3, From a ship, a light on the edge of a breakwater bore 045° T . The ship was steering a course of 060° T. After travelling for 30 minutes, the same light bore 280° T and distance off 2.0 nautical miles. Find the speed of the vessel.
