Answer:
See below
Step-by-step explanation:
1. Colloid
B) Microscopic insoluble particles that are suspended throughout another substance.
Milk is a colloid. It consists of small fat globules suspended in water.
2. Emulsion
D) Two or more liquids that are not normally mixable.
Mayonnaise is an emulsion. It consists of oil, egg yolks, vinegar, and seasonings. Normally, the oil and vinegar (95 % water) do not mix. Without the egg yolk , they would quickly separate. Egg yolk contains the emulsifier, lecithin, which is attracted to both oil and water and stabilizes he mixture.
3. Solution
A) A solute that is evenly distributed within the solvent.
Sugar syrup is a solution of sugar in water.
4)Homogeneous
C) A mixture that has its components distributed evenly within the substance.
A homogeneous mixture has only one phase. For example, the sugar syrup is homogeneous, because, even with a powerful microscope, you can't see a boundary between the sugar particles and the water.
An object which experiences either a change in the magnitude or the direction of the velocity vector can be said to be accelerating. This explains why an object moving in a circle at constant speed can be said to accelerate - the direction of the velocity changes.

Explanation:
Lorenz force exerted on electron by magnetic field is
F=e*v*H, where e=1.602E-19 C, H=3.64E-3 T, v is speed of electron;
? meanwhile Lorenz force is centripetal force F=m*v^2/r, where mass of electron m=9.11E-31 kg, r is radius of the path of electron;
? therefore F=F; e*v*H = m*v^2/r; eH=m*(v/r), hence
v/r = eH/m =w is angular speed of electron, hence
T=2pi/w =2pi*m/(eH) is period of rotation of electron;
e- and e+ starting at the same point are moving in the same circular path and in opposite directions, and should meet in T/2 time;
T/2 = pi*m/(eH) = pi*9.11E-31 /(1.602E-19 *3.48E-3) =5.13E-9 s;
Answer:
Heat and water.
Explanation:
Increased evaporation means more water vapor in the air and more energy ready to be liberated in the hurricane's thunderstorms as water vapor condenses.
