If I were to begin walking toward an object that is 1 mile away from me and stopped half way for 1 second then resumed walking at double the speed and walked half the distance again and again dobled my speed, and continued this process for eternity, would I not eventually be walking faster than the speed of light and never reaching the object?

When a liquid is released in 0 gravity it takes the form of a sphere because of surface tension.
When rock, ice, dust, and other material clump together and form a planet it is called gravitational force.
What's the difference in the two forces?

Assuming that the distance from you to the sun is about 400 times the distance from you to the Moon,
a)find the ratio of the sun's diameter to the Moon's diameter.
b) What is the ratio of the sun's volume to the moon's volume?
c)Position a small coin in your view so that it just eclipses the full moon, and measue the angle it subtends at the eye. From this and the Earth- Moon distance(= 3.8*10^5 km), find the moo's diameter.

Please explane your answer and not just show it , I would really like to learn how to do it just not have the answers. Thank you.

dimensions of 40 cm * 40cm* 30cm (height). The receptacle is to be initially filled to the top. The wine can be purchased in bottles of the sizes given in the following table. Purchaseing a larget baottle instead of multiple smaller bottles decreases the over all cost of the wine. To minimize the cost,
a) which bottle sizes should be purchased and how may of each should be purchased and , oce the receptacle is filed how much wine is left over in terms of
b) standard bottles and c) liters?

1 standard bottle
1magnum = 2 sstandard bottles
1 jeroboam = 3 standard bottles
1 rehoboam = 6 standard bottles
1 methuselah = 8 standard bottles
1 salmanazar = 12 standard bottles
1 balthazar = 16 standard bottles = 11.356L
1 nebuchadnezzar = 20 standard bottles

Please show me how to do this not just the answers. I really want to learn how. Thank you.

This is a philosophical question. If you can always ask yourself the question of ...what was going on 10 billion years before, no matter where you are in time, suggests that time goes back infinitely. If this is true then how did we ever get to this point in time?

Estimate the acceleration you subject yourself to if you walk into a brick wall at a normal walking speed. (Make a reasonable estimate of your speed and of the time it takes you to come to a stop, and explain those numbers also.)
