Solve the problem.
-The grade resistance F of a car traveling up or down a hill is modeled by the equation F = W sin ϴ where W is the weight of the car and ϴ is the angle of the hill's grade (ϴ > 0 for uphill travel, ϴ < 0
For downhill travel) . A 2025-lb car has just rolled off a sheer vertical cliff (ϴ = -90°) . What is the
Car's grade resistance?
Electrolytes
Substances that produce ions and conduct electricity when dissolved in water.
Not Electrolytes
Substances that do not dissociate into ions in solution and therefore cannot conduct electricity in their molten or aqueous states.
Non-electrolytes
Substances that do not produce ions when dissolved in water, and hence do not conduct electricity in solution.
Non-electrolyte
A substance that does not readily ionize when dissolved or melted and is therefore a poor conductor of electricity.
