Answer:
Geothermal energy is used. Dry system plants are set up for harnessing this energy.
Explanation:
<span>a) All the 26m should be used to bent into a square to maximize the total area (= 42.25 m2)
b) 1.4136m should be bent into a square and the rest (= 24.586m) should be bent into an equilateral triangle to minimize the total area (= 29.0835m2)</span>
Answer:
the kinetic energy decreases
Explanation:
When a liquid is cooled, the kinetic energy of the particles decreases. The force of attraction between the particles decreases, the space between the particles decreases, and the matter changes its state to solid.
Answer:
time =20s
Explanation:
Average speed = Distance/time
time = Distance / Average speed
Where Distance = 100meters and speed =5m/s
So,
time = 100m/5m/s
time =20s
Water<span> can </span>dissolve salt<span> because the positive part of </span>water<span> molecules attracts the negative chloride ions and the negative part of </span>water<span> molecules attracts the positive sodium ions. The amount of a substance that can </span>dissolve<span> in a liquid (at a particular temperature) is called the solubility of the substance. So the solute is the salt and the solvent is the water. I believe that is correct.</span>
