If you drop a brick and a penny at the same time which would hit the ground first?

The coin.
The reason is because the tube is filled with air. Air caused air resistance. The feather has much greater air resistance than the coin, so the air will hold the feather up for a bit while the coin will likely turn on it's side and fall quickly.
Now, if it was a tube without air (a vacuum), they would fall at the same rate because there is no air resistance. Gravity acts on the same objects in the same way, essentially. The weight of the two objects is different, so gravity actually puts an amount of force on them differently. However, because gravity does this gravity accelerates both objects at equal speeds.

However it has nothing to do with the weight of the feather or the penny, but rather their respective aerodynamic values. If you screwed the feather up and pressed it into the same shape and size as the penny, it would fall at the same speed, despite being much lighter. Gravity is a constant and the speed things fall at is a constant, 9.8 meters per second/per second.
Weight has nothing to do with how fast things fall, only wind resistance. Take two 16 ounce soda bottles, open one drink eight ounces. The unopened bottle is twice as heavy as the opened bottle. Close the bottle you just drank half of and drop them at the same time from a tall building, they will hit the ground at the same time. That is because gravity is a constant and the velocity of any falling object is 9.8 meters per second/per second.
Acceleration is the same for all objects at 9.8m/sec/sec.
Acceleration due to gravity near the earth's surface is the same for all objects regardless of their mass.
This is because acceleration is inversely proportional to mass:
a = F / m
If you substitute the "force of gravity" equation above for F in this simple equation, and assume m here is m1 there, you'll find you have m1 (mass of the falling object) on both sides of the fraction, so they cancel out - acceleration due to gravity doesn't change with the mass of the object. But the force most definitely does.
Force and acceleration are two very different things. Confusing them leads to wrong answers and further confusion in later topics.

to the bottom of the tube, where they will then stop falling.
If you were to drop them both from the exact same place at the exact same time,
then there would be some in the crowd of onlookers who would be amazed at the
fact that the coin and the feather both hit the bottom at the exact same time.

Which would weigh more a brick made of iron or the same size brick made of lead?
Lead brick
How much would 1000 penny weigh?
How much would 1000 penny weigh?
Where does sound travel faster wood or brick?
You mean which one does it travel faster in? It would be a brick because of how tightly packed the molecules in the brick are together. Wood, which is a lot more fragile that brick, does not allow sound to travel through it as fast.
What would fall first a rock or a feather?
The mass is irrelevant, the only factor that effects how fast anything falls on earth is air resistance. The feathers obviously have more air resistance than the rocks and so the rocks will fall faster. If this was done in a vacuum however one gram of feathers would fall at the same rate as a tone of rocks.
How do you tell if you have an authentic 1944 steel penny?
The first clue would be that it would stick to a magnet. If not, it can't be made of steel. If it does stick, the coin would have to be authenticated by one of the major grading agencies.
If you drop a penny and a text book at the sametime. which one will hit the ground first?
If a penny and a text book were dropped in a vacuum then they will both hit the ground at the same time. This refers to Newton's laws. If they are dropped at the same time on earth then the text book would hit the ground first.
Why would a brick hit the ground first before an apple?
In the absence of an atmosphere it wouldn't. Even with an atmosphere any air resistance would be negligible.
Which would hit the ground first a tennis ball or a baseball?
They would both hit at the exact same time; if you let them go at the exact same time.
A brick 10 meters off the ground has more energy on the moon than it does on the earth?
No, the brick may possibly have a greater impact on the moon than on earth, but only because much of the energy the brick would have on earth would be spent overcoming the friction of the atmosphere.
Why would a penny hit the floor before a piece of paper would?
It depends on the paper. If it is large and flat, then it will almost certainly land after the penny. If it is folded up nice and small and dense, then it will hit the ground at about the same time as the penny.
Why would u find a penny from the ground?
luck or because u could look down
What was the name for the peasants who would pay a penny to sit on the ground to see Shakespeares play?
They were called "groundlings."
Would a bowling ball and a penny hit the ground at the same time if dropped from an equal height?
Yes
How long would it take for a 50 year old house to burn down to the ground?
That would depend on what it is made of, a brick house may be gutted by fire but it would not burn down to the ground. Wooden houses can burn to the ground in less than an hour if they are not well-constructed.
What would happen if you dropped a penny off the Empire State Building and it made it to the ground?
If you drop a penny off the Empire State Building, it falls at its own terminal velocity after falling about 200+ metres (that's a guess but it's around 200). A penny's terminal velocity is roughly half of a falling person's terminal velocity. A falling skydiver will reach a maximum of around 130mph, so a penny will fall at approximately 65mph.
What did it coast to get into plays in Shakespeares time?
In some places you would pay a penny and stand on the ground watching the play
Why does a penny fall faster than a feather is it because gravity acts less on a feather?
Purely air resistance, the feather floats on the air. The mass is irrelevant. If a penny was dropped at the same time as a brick (ignoring wind resistance) both would hit the ground at the same time. Look up Galileo's tower of Pisa experiment. http://en.wikipedia.org/wiki/Galileo%27s_Leaning_Tower_of_Pisa_experiment This also includes a video of a feather and a hammer being dropped on the moon (where there is no air). Both hit the ground together.
