Check all that apply! if liquid water is exposed to normal atmospheric pressure, what needs to change in order to change its state of matter? a) mass of water b) temperature of water c) shape of container d) energy of water

If liquid water is exposed to normal atmospheric pressure, then the only way to make it change its state of matter is to manipulate its temperature.

Cool it to 0°C (32°F) or lower and it becomes solid.  

Heat it to 100°C (212°F) or higher and it becomes gas.

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft

pythagoras' theorem

square root (-5^2+9^2)

square root (25+81)

square root (106)

angle is tan^-1(9/5)
