Grade 12 math: vectors as forces?

Physics
1 answer:
sashaice [31]3 years ago
4 0
Larger tug force = 2*cos20 forward + 2*sin20 to the right (starboard) 
<span>Smaller tug force = 1*cos15 forward + 1*sin15 to the left (port) </span>

<span>Resultant force forward = 2*cos20 + 1*cos15 = 2.8453 (4dp) </span>
<span>Resultant force to right = 2*sin20 - 1*sin15 = 0.4252 (4dp) </span>

<span>Angle of resultant force = arctan(0.4252 / 2.8453) = arctan(0.1494) = 8.5 degrees</span>

What property of all ionic compounds make them electrolytes
steposvetlana [31]

Property of all ionic compounds make them electrolytes;

An electrolyte is a compound that conducts an electric current  it is also in the form of aqueous solution or in the molten state, the ionic compounds are electrolytes because they dissociate into ions.

Explanation:

  • Property of all ionic compounds make them electrolytes;
  • An electrolyte is a compound that conducts an electric current  it is also in the form of aqueous solution or in the molten state, the ionic compounds are electrolytes because they dissociate into ions.
  • Most of the unique properties come from the hydrogen bonds which holds the water together.
  • when a solutes break away from the crystal, the negatively and positively charged ions become surrounded by solvent molecules and it dissolves the ionic crystal.
