15. Explain how each of the following creates electrical energy:
a.
Solar
Hydro
Tidal
Wind
OTEC
Biomass
Geothermal

Answers

Solar- technologies convert sunlight into electrical energy either through photovoltaic panels or through mirrors that concentrate solar radiation.

Hydro- a hydraulic turbine converts the energy of flowing water into mechanical energy. A hydroelectric generator converts this mechanical energy into electricity

Tidal- energy is a form of hydropower that works by harnessing the kinetic energy created from the rise and fall of ocean tides and currents, also called tidal flows, and turns into unusable electricity

Wind- turns the propeller like blades of a turbine around a rotor, which spins a generator, which creates electricity

OTEC- plants pump large quantities of deep cold seawater and surface seawater to run a power cycle and produce electricity

Biomass- is burned in a boiler to produce high-pressure steam. This steam flows over a series of turbine blades, causing them to rotate. The rotation of the turbine drives a generator, producing electricity

Geothermal- power plants use steam to produce electricity. The steam comes from reservoirs of hot water found a few miles or more below the earth’s surface. The steam rotates a turbine that activates a generator, which produces electricity

Recycling of solid waste minimizes pollution. Give reason.

Answers

Recycling prevents the emissions of many greenhouse gases and water pollutants, and saves energy. Using recovered material generates less solid waste. Also, when products are made using recovered rather than virgin materials, less energy is used during manufacturing, and fewer pollutants are emitted.

Compare and Contrasts Biotic Factors and Abiotic Factors. What are they?
How are the alike.
How are the different?

Answers

A biotic factor is a living thing that has an impact on another population of living things or on the environment. Abiotic factors do the same thing, but they are non-living. Together, biotic and abiotic factors make up an ecosystem. To survive, biotic factors need abiotic factors.
Biotic factors are living organisms that typically contribute in some way to their environment. Some examples of Biotic factors include plants, animals, cells and they are typically producers, consumers or decomposes. Unlike Biotic factors, Abiotic factors are the non-living part of an ecosystem. They are typically chemical or physical, some abiotic factors include water, sunlight, soil, and temperature. Both Biotic and Abiotic factors are required in an ecosystem to properly function.

Maria claimed that she could not see through the safety goggles and wore them on top of her head rather than over her eyes. While pouring an unknown chemical into a beaker, she accidently splashed some of the chemical in her eyes. What should Maria immediately do next?

Answers

Answer:

She should immediately rinse or flush her eyes with water.

Explanation:

One of the most important precautionary measure to be taken when working with explosive chemicals in the laboratory is the use of safety goggles. However, in this case, Maria claimed that she could not see through the safety goggles and wore them on top of her head rather than over her eyes.

Maria accidentally splashed some chemicals into her eyes while trying to pour it into a beaker. The primary or initial response to this happening is to immediately FLUSH OR RINSE her eyes with water. This will flush away the chemical from her eyes before it can have its detrimental effect.

Answer:

proceed to the eye wash station, open her eyes, and rinse them for at least 15 minutes
