Answer: melting point.

Explanation:

Freezing point is the temperature at which liquid phase changes to solid phase. Freezing point of water is 0^0C.

H_2O(l)\rightarrow H_2O(s)

Melting point is the temperature at which solid phase changes to liquid phase. Melting point of water is 0^0C.

H_2O(s)\rightarrow H_2O(l)

Melting and freezing are reversible processes which takes place at 0^0C for water.

Boiling point is the temperature at which vapor pressure of the liquid becomes equal to atmospheric pressure.

Sublimation point is the temperature at which gaseous phase changes to solid phase.

Thus the freezing point of water is the same as its melting point.

A pendulum is hanging from a tower. The pendulum almost touches the ground and has a period of 18.0 s. What is the height of the
nadya68 [22]
We apply the following equation

T = 2π * sqrt (L/g)

Where g is the gravity = 9.8 m/s^2

L is the longitude of the pendulum (Height of the tower)

T is the period. (T = 18s)

We find L.............> (T /2π)^2 = L/g

L = g*(T /2π)^2...........> L = 80.428 meters
