Answer:

1. For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.

2. The Tyndall Effect is the effect of light scattering in colloidal dispersion, while showing no light in a true solution. This effect is used to determine whether a mixture is a true solution or a colloid.

A Ground Fault Circuit Interrupter (GFCI) is designed to do which of the following?
Ymorist [56]

Answer: Protect people from severe and sometimes fatal electrocution by monitoring for electrical leakage to ground.

Explanation:

The main purpose of a Ground Fault Circuit Interrupter (GFCI) is to ensure that when a person gets electrocuted, the flow of electricity is cut off quickly so that no serious injuries or death occurs.

It works by monitoring the electrical leakage to the ground by checking to see if the current going to and coming from the equipment differ by a certain amount and if it does, the GFCI will interrupt the circuit.

spin [16.1K]

Answer:

$18,750

Explanation:

Present value (PV): $12,000

Tenor: 3 years

Future value (FV): $15,700

We have the formula:

FV = PV*(1+ annual rate) ^ number of year

15,700 = 12,000 * (1 + rate) ^3

-> Rate = (15,000/12,000)^(1/3) – 1 = 7.722%

If Sam invest in 6 year, the amount he expect to have is the future value in below calculation:

FV = 12,000 * (1+ 7.722%)^6 = 18,750
