Copy of Estimating Angles

Illuminance is a measurement of how much light is incident on a surface. It varies with the square of the distance of the object from the light source. Illuminance (lx)- amount of light falling on 1 m^2 area Please answer numbers 1 and 2 1. Compute for the illuminance in your room. 2. Search for the ideal illuminance in the areas of the house (living area) and give area in your house that needs more light. Kindly give explanation how'd you come up with your answer.

3 Math Practice Name: Physics 357 Some Initial Math Practice, Part 2 Unit analysis is the method by which you use ratios, or fractions, to convert quantities between units, e.g., inches to meters or seconds to minutes. The trick is to establish ratios whereby the unit that you want lives in the numerator and does not get canceled out by the denominator. Here are two examples: How many quarters are in $5? Well, you know there are 4 quarters in a dollar, so.. quarters X 5 dollars 0 quarters 1 dollar 1 Note that the dollars in the numerator cancels out with the dollar in the denominator, so what you're left with is quarters. How many dollars is 17 quarters? 1 dollar 17 quarters 4.25 dollars - X 4 quarters 1 Note that we just flipped the conversion ratio to get the units that we wanted in the numerator! 1. How many miles is 2200 meters? (By the way, don't just google it! - do a web search or look in a physics text to find the conversion ratio and then set it up like the example above) 2.…
