What is happening to the water molecules as it changes from ice to liquid water? * They are losing energy, can’t move only vibrate
They are gaining energy, can move and slide past each other
They are moving at high speeds and are far from each other
They are gaining energy, moving slowly until they evaporate

They are gaining energy, can move and slide past each other.

Explanation:

Because as ice melts, the molocules gain energy/heat which warm them up and are able to slide/move apart from each other.

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this

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
