when a substance such as ice melts, its temperature increases. desrcibe what happens to the arrangment of water molecules as the
trasher [3.6K]

Explanation:

The water molecules begins to leave their fixed position and begins to move as the temperature increases.

When ice melts, it undergoes a state change from solid to liquid and with increasing temperature becomes a gas.

  • The basis for this is the increasing movement of the molecules of the water as it transitions from one phase to another.
  • In the ice, the molecules are locked and fixed in the lattice
  • As the temperature increases, the average kinetic energy of the particles rises.
  • This makes the structure of the ice to collapse and forms liquids.
  • By the virtue of this, they flow and move over one another
  • With increasing temperature, the bonds are broken and vapor forms

Suppose you exert 150 n on your refrigerator and push it across the kitchen floor at constant velocity. what friction force acts
Pachacha [2.7K]
Due that the velocity is constant that means that friction force is equal to the force exert by you, otherwise the refrigerator will accelerate or decelerate and in both cases velocity will not be constant.  
So then the friction force between refrigerator and floor is 150 Newtons.

Guyz... Its my first question in this app... Pls do answer​
Basile [38]

Answer:

1.414

Explanation:

Snell's law states:

n₁ sin θ₁ = n₂ sin θ₂

where n is the index of refraction and θ is the angle of incidence (relative to the normal).

The index of refraction of air is approximately 1.  So:

1 sin 45° = n sin 30°

n = sin 45° / sin 30°

n = 1.414

Round as needed.
