The freezing point of water is the same as its a. melting point. b. boiling point. c. sublimation point. d. evaporation point.
2 answers:
Answer: melting point.
Explanation:
Freezing point is the temperature at which liquid phase changes to solid phase. Freezing point of water is .
Melting point is the temperature at which solid phase changes to liquid phase. Melting point of water is .
Melting and freezing are reversible processes which takes place at 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.

Given:
B = T
V=
q = 2.5 × C
α = 90
To find:
Force = ?
Formula used:
Force on the moving charge is given by,
F = q V B sin α
Where F = force exerted on moving charge
V = velocity of charge
q = charge
α = angle between direction of V and B
Solution:
F = q V B sin α
Where F = force exerted on moving charge
V = velocity of charge
q = charge
α = angle between direction of V and B
F =
F = 37.5 ×
F = 3.75 Newton
Thus, the force acting on the moving charge is 3.75 Newton.
