Let's see how bad at math you guys are.
As the resident physicist here, I would love to see you guys take on this middle school level physics problem, and explain your answer.
I doubt you can.

6 RespuestasEditado por Ice Cold Arson: 6/10/2016 5:43:11 AMThat ain't even math. Let's start off with a simple problem. Let f(x) = (ax + b)/(cx +d) a,b,c,d are non zero. If f(7) = 7 and f(11) = 11 and f(f(x)) = x for all x except -(d/c). What is the unique number not in the range of f? [spoiler]whoever solves this gets a cookie and the next problem[/spoiler]

1 RespuestaEditado por Cameo Cream: 6/10/2016 5:37:15 AMFlies push their mass downwards due to basic properties of flight. So the inaccurate answer would be 1kg, the weight of the jar, as long as the flies are not in contact with the Jar. Im basing this on their size and placement in the Jar If we are taking unrealistic assumption for flies. Then it would weigh 1.5. Helicopters work by pushing their weight downwards to overcome mass. Equal and opposite reaction. The higher the helicopter, the more the pressure on the ground dissipates I don't see this as a very realistic and non misleading question. Whatever teacher drew this is moronic.

2 RespuestasThe answer is none of the above. The total mass for the entire flask must include the air inside it. Thus, the mass would be greater than 1.5. If we actually looked at the weight. Then the net weight that would be represented on here would fluctuate between 9.81 N and 14.72 N whether depending on the flies' movement.

Is it an open top jar?

1 RespuestaAnd how the hell are 5 flies going to weigh half a kilo?
-
I have solved the trick. Assuming this is taking place during the current 21st century, the flies explode due to a lack of oxygen intake for their size.
-
Wouldn't it be 1 kg because the flies are flying inside? I've seen you say 1.5 but if they are not touching scale or jar they wouldn't give any weight would they? I know w/ air it brings it up barely any but a fly flying over a scale gives no weight... so why do you say 1.5?
-
1 Respuesta1kg because the flies are flying and wouldn't affect the weight. That wasn't that hard.

4 RespuestasHow can a scale read? It's an inanimate object

1kg because the flies are flying

1. Why is there no door time tag? 2. What is the correct answer? 3. I know nothing of physics

1 RespuestaEditado por Chaotic_Wilhelm: 6/8/2016 12:42:33 PMI would hardly call that a physics question, try this one. Two parallel plates are 2 mm apart and have a potential difference of 100V between them. An electron is placed halfway between the plates. What is the magnitude of the force on the electron? (A) 8.0 × 10–18 N (B) 1.6 × 10–17 N (C) 8.0 × 10–15 N (D) 1.6 × 10–14 N

2 RespuestasEditado por Tucker: 6/6/2016 10:46:23 PMLet's see how bad at grammar you are: "flies weighs" Let's see how bad at physics you are: Weight is a force. It is measured in Newtons. Mass is a scalar measurement that can be determined through the use of a triple beam balance. It is measured in grams.
-
Welp no one here has heard of Newton's laws
-
Well. It is completely dependent on whether the flies are flying or not. "Weight" is actually Force due to Gravity, or in this case, Mg. The flies are resisting gravity entirely in flight, meaning that they have an Mg=0. Obviously the Jar is 1.0kg, therefore the total weight is 1.5 kilograms.
-
Clearly it reads 111111
-
6 RespuestasIt should just weigh 1 kilogram then. The flies are in the air thus not putting any pressure on the scale.
