user: Question: The Figure below shows decibel levels of several different sounds. As decibel levels get higher, sound waves have greater intensity and sounds are louder. For every 10-decibel increase in the intensity of sound, loudness is 10 times greater. Therefore, a 30-decibel “quiet” room is 10 times louder than a 20-decibel whisper, and a 40-decibel light rainfall is 100 times louder than the whisper. High-decibel sounds are dangerous. They can damage the ears and cause loss of hearing.  James is attending a concert. When he first walks in the concert hall there aren't that many people there and it is relatively quiet. As the room fills up it starts to get a bit louder. And when the concert starts its so loud that it is almost painful for him as he is sitting near the speakers.  Will the decibel levels have increased or decreased in the time since James arrived at the concert to when the show started?
Answer: increase


[Q]: For an inclined plane, the input distance is the length of the sloping surface, and the output distance is the maximum height of the inclined plane. This was illustrated in Figure above . Because the sloping surface is always greater than the height of the inclined plane, the ideal mechanical advantage of an inclined plane is always greater than 1. An inclined plane with a longer sloping surface relative to its height has a gentler slope. An inclined plane with a gentler slope has a greater mechanical advantage and requires less input force to move an object to a higher elevation.  John works as a mechanical engineer in the auto industry. He is testing three surfaces, surface A, surface B, and surface C for their usability. Surface A has a gentler slope, surface B has a steeper slope, and surface C doesn't have any sloping. He needs to figure out advantages and disadvantages of each slope.  Which surface would need less input force to move an object upward, surface A or surface B?
****
[A]: surface A


input: Please answer the following: Insecticide control of aphids is difficult, as they breed rapidly, so even small areas missed may enable the population to recover promptly. Aphids may occupy the undersides of leaves where spray misses them, while systemic insecticides do not move satisfactorily into flower petals. Finally, some aphid species are resistant to common insecticide classes including carbamates, organophosphates, and pyrethroids.For small backyard infestations, spraying plants thoroughly with a strong water jet every few days may be sufficient protection. An insecticidal soap solution can be an effective household remedy to control aphids, but it only kills aphids on contact and has no residual effect. Soap spray may damage plants, especially at higher concentrations or at temperatures above 32 °C (90 °F); some plant species are sensitive to soap sprays.  Pam and Mary were two gardener friends. They both had some aphid infestations, but Mary had more aphids on her farm, so she used every method and insecticide available to get rid of them, with limited success.  Which farmer dealt with more aphids resistant to carbamates?
++++++++++
output: Mary


Please answer this: Light may transfer its energy to matter rather than being reflected or transmitted by matter. This is called absorption . When light is absorbed, the added energy increases the temperature of matter. If you get into a car that has been sitting in the sun all day, the seats and other parts of the car’s interior may be almost too hot to touch, especially if they are black or very dark in color. That’s because dark colors absorb most of the sunlight that strikes them.  There are two cats sitting outside in the sun. One of them has white fur and one of them has black fur. Tina sees them and goes to pet them both.                                                            Robert is planning a beach trip and needs to buy a new lounge chair to sit in because his old one is broken. At the store he sees two chairs that he likes. One of the chairs is dark blue and one of the chairs is light blue.  If Robert bought the dark blue chair would it absorb more or less light than the light blue chair?

Problem: Sometimes muscles and tendons get injured when a person starts doing an activity before they have warmed up properly. A warm up is a slow increase in the intensity of a physical activity that prepares muscles for an activity. Warming up increases the blood flow to the muscles and increases the heart rate. Warmed-up muscles and tendons are less likely to get injured. For example, before running or playing soccer, a person might jog slowly to warm muscles and increase their heart rate. Even elite athletes need to warm up ( Figure below ).  Two teams were competing in a 5 km race. White team warmed up before the race, but Blue team arrived with a bus late and didn't have time to warm up properly before the race.  Which team didn't do a slow increase in the intensity of physical activities before the race?

A: Blue


input: Please answer the following: One of the main advantages of adopting a strong foreign currency as sole legal tender is to reduce the transaction costs of trade among countries using the same currency.[13] There are at least two ways to infer this impact from data. The first is the significantly negative effect of exchange rate volatility on trade in most cases, and the second is an association between transaction costs and the need to operate with multiple currencies.[14] Economic integration with the rest of the world becomes easier as a result of lowered transaction costs and stabler prices.[2] Rose (2000) applied the gravity model of trade and provided empirical evidence that countries sharing a common currency engage in significantly increased trade among them, and that the benefits of currency substitution for trade may be large.[15]  Two countries are considering adopting the same currency. Country A will begin to use the currency of Country B if they agree to make this change. Currently there is a 2 to 1 exchange rate on currency from country A to country B but this changes over time. Also in order to exchange the currency you have to pay a 5% fee on whatever the amount is you would like to exchange. Under the new system there will be no exchange rate and there will no longer be a reason to pay the transaction fee as everyone will have the same currency.  Which countries currency will be used?
