B. Water molecules move from their fixed position.
C. Water molecules lose energy.
D. The temperature of the ice increases as it melts.
The answer for this question is part B that is Water molecules move from their fixed position.
This is because when water is freeze it is in a solid condition that means the molecules are held together tightly and are are vibrating in their fixed positions.
As soon as the molecules gain energy they start to move around from their fixed positions and turn into a liquid.
In the process of doing so ice melts and becomes water.
"When The motional emf generated between the ends of the wire is e = 17745.1 V".
When Motional EMFs in the Earth’s weak magnetic occupation are not ordinarily very large, we would notice voltage along metal rods, Than such as a screwdriver, during ordinary motions. For illustration, a simple computation of the motional emf of a 1 m rod moving at 3. 0 m/s perpendiculars to the Earth’s field gives emf is = Bℓv
Then Length, l is = 4.32 x 10^4 m
Then speed, v is = 7.07 x 10^3 m/s
Now the magnetic field, B is = 5.81 x 10^-5 T
Now, The formula for the motion emf is given by
e is = B x v x l
e is = 5.81 x 10^-5 x 7.07 x 10^3 x 4.32 x 10^4
Therefore, e = 17745.1 V

Answer:
Explanation:
Length, l = 4.32 x 10^4 m
speed, v = 7.07 x 10^3 m/s
magnetic field, B = 5.81 x 10^-5 T
The formula for the motion emf is given by
e = B x v x l
e = 5.81 x 10^-5 x 7.07 x 10^3 x 4.32 x 10^4
e = 17745.1 V
2. gaseous solution
3. compound
4. colloid
5. element
a. oceans
b. clouds
c. oxygen
d. air
e. water
1) Liquid solution: Oceans
2) Gaseous Solution: Air
3) Compound: Water
4) Colloid: Cloud
5) Element: Oxygen
Solutions are those mixtures which have uniform composition. The size of solute is around 1 Angstrom hence, the particles of solutes can not be seen and the interactions make the overall solution transparent.
Compounds are those substances which are formed chemically by the reaction of two different elements like,
O₂ + 2 H₂ → 2 H₂O
Colloids are also mixtures but these are intermediate between true solutions and suspensions. Also, the solute size is greater than that of solute size in solutions and is about 10 Angstrom. Examples include Clouds, Fog, Moist, Aerosol sprays e.t.c.
Elements are those substances which either are made up of single atoms like noble gases or are molecules made up of same elements like O₂, H₂, Cl₂, N₂ e.t.c.
