An object is dropped from a height of 6, 400 feet. The amount of time, in seconds, it takes for the object to hit the ground can be found by solving the equation
- 16t^2 + 6, 400 = 0. How many seconds will it take to hit the ground?
The object will take seconds to hit the ground.

1/800 is the right answer

it is a horizontal line.

large crystals result from very slow cooling.

evaporation of water: this would produce an evaporite which is a sedimentary rock. like a salt pan in a desert. not possible to have volcanic rocks originate this way.

crystalization in molten earth: slow cooling over time. (hundreds to millions of years)

crystalization at earth's surface: this results in fast cooling. (a few hours to a few months or years)

crystalization from cooling off hot water: that would be a hydrothermal deposit. while associated with volcanics they are not volcanic rocks themselves and usually occur fairly rapidly.
