Is a power chain the last steps of braces?

A power chain is a common orthodontic accessory used with braces to close gaps between teeth or to maintain alignment. It is often used in the latter stages of orthodontic treatment to fine-tune the positioning of the teeth and achieve the final desired outcome.

What is a tidal budge?

A Tidal Bulge is a high tide. It is a bulge of water on the side of the earth under the moon, and it is caused by the moon's gravity attracting the water.

There is a similar bulge on the opposite side of the earth, away from the moon, to counterbalance the moon bulge.

The areas between the two bulges experience low tide.

What loses energy when you use tidal power plants?

Tidal power plants harness the energy from ocean tides, which is primarily derived from the gravitational pull of the moon and the sun. In using this energy, the kinetic energy of the moving water is partially converted into electricity, meaning the water loses some of its energy as it flows through the turbines in the power plant.

What are disadvantages to tidal power?

It can only be used successfully in a few places round the world, where a large bay or estuary is so shaped (like Canada's Bay of Fundy) that a huge amount of water rushes through a narrow opening when tides rise and fall.

There are some substantial issues associated with generating power through tides.

  • The impact on local marine life
  • the concept is still in the experimental stages
  • If enough power is harness from Tides, a slowing of our annual orbit around the sun will occur causing as much as a 24 hour change every 2000 years.

Is tidal power a good power source?

  • They don't think much about it.
  • Tidal power is only suitable at selected locations round the world.
  • The community is more likely to think about renewable energy in general and think that it is good.
  • The community knows that we have to reduce our reliance on fossil fuels (coal, oil and natural gas), because the burning of them is causing global warming.

How often do tidal disturbances happen?

Tidal disturbances, such as storm surges and tsunamis, can occur sporadically and are influenced by various factors like weather patterns and seismic activity. While some regions may experience tidal disturbances more frequently due to their geographic location, the exact frequency can vary greatly depending on the specific type of disturbance and its associated cause.

Why is a tidal power a flow resource?

Tidal power is considered a flow resource because it harnesses the flow of water caused by the regular rise and fall of tides. This flow of water can be used to turn turbines and generate electricity, similar to how wind or water currents are used as energy sources.

How does your tidal volume compare with the average tidal volumes found in table 4-2?

no!!!!!!! i asked it though ot would be nice if someone else answered the question i asked

What is the percent of tidal power used in France?

The La Rance station in France, generates 240 megawatts of power. Currently, France is the only country that successfully uses this power source. This is a very small portion of the total energy requirements of France (well under 1%)

On a related noted:

French engineers have noted that if the use of tidal power on a global level was brought to high enough levels, the Earth would slow its rotation by 24 hours every 2,000 years. We could get rid of some of our leap years!

Can tidal energy be conserved?

Tidal energy itself cannot be conserved, as it is a renewable resource that replenishes naturally with the ebb and flow of tides. However, the technology used to capture and convert tidal energy into electricity can be improved to be more efficient and sustainable. Efforts to minimize environmental impacts and maximize energy output from tidal sources can help in utilizing this renewable energy source effectively.

How far will the cam follower rise or fall?

The distance a cam follower rises or falls depends on the shape of the cam profile. The follower's movement is directly related to the shape and dimensions of the cam. The follower will rise or fall based on the specific design and intended function of the cam system.

How does tidal fence work?

A tidal fence is a barrier built across a tidal channel or river to harness the energy of the flowing tide. The fence captures the kinetic energy of the water flow and converts it into electrical energy using turbines or generators. As the tide flows in and out, the movement of the water spins the turbines to generate electricity.

What causes of the Tidal Streams?

Tidal streams are caused by the gravitational forces of the Moon and the Sun acting on the Earth's oceans. The alignment and relative positions of these celestial bodies create variations in the water levels, resulting in the movement of tides. Geographical features of coastlines and ocean floor topography also influence the speed and direction of tidal streams in different regions.

What does co-tidal line mean?

A co-tidal line is a line on a map connecting points on the Earth's surface that experience high tide simultaneously. It represents the progression of high tide across an ocean or sea due to the gravitational attraction of the moon and sun.

What is the minimum tidal energy required for a practical tidal plant?

That depends on the kind of plant. There are two major types:1. Tidal turbines

2. tidal barrages


1. Tidal turbines are like wind-turbines but underwater. They need a current speed of at least 1m/s to start producing energy but current models are not economically viable for anything below 2m/s


2. Tidal barrages are like dams across a bay or an estuary. Theyutilizethe difference in water level between high and low tide. They open their gates as the tide comes in to allow the water to collect behind the dam. at the highest point of the tide the gates close until low tide is reached. the water is then release via turbines until the water level behind the dam is equal to the sea level. When the tide comes in again the cycle repeats. These kind of tidal plants need a difference between high and low tide of at least 5-7 meters although the bigger the difference the better.

What group of people might be interested in knowing tidal?

Mariners, surfers, fishermen, coastal residents, and environmentalists may all be interested in knowing tidal information to plan activities, monitor sea conditions, or assess the impact of tides on coastal ecosystems.

Why did the Sudanic Kingdom rise and fall?

The Sudanic Kingdoms in West Africa rose due to increased trade and agricultural productivity, leading to wealth and power. They fell due to internal conflicts, invasions by foreign empires, and the disruption caused by the transatlantic slave trade.

What are the complications of tidal volume?

Complications of tidal volume include barotrauma (lung damage from high pressures), volutrauma (lung damage from excessive stretch), and ventilator-associated lung injury. Inadequate tidal volume can lead to hypoventilation and hypercapnia, while excessive tidal volume can cause ventilator-induced lung injury. Close monitoring and adjustment of tidal volume is important to avoid these complications.

How many megawatts do tidal turbines produce in day?

A typical nuclear power plant produces 500 to 5000 megawatts of power. If we take 2000 as average, an average plant produces 2000 megawatt hours in an hour, or 48,000 megawatt hours in a day.

But please note: Technically, this does not answer the question asked, because the question asked for megawatts, not megawatt hours. The question as asked is like asking how many horsepower a car can produce in a day.

The measure of electrical output over a period of time is a watt hour, or, in this case, the megawatt hour. So the question answered was, "How many megawatt hours does a nuclear power plant make in a day?"

What is tidal dynamics?

Tidal dynamics refer to the gravitational forces between celestial bodies, such as the Earth, Moon, and Sun, that cause the oceans to bulge and recede. These forces create the daily rise and fall of sea levels, known as tides. Tidal dynamics also impact ocean currents and coastal ecosystems.

What does MMLW mean in reference to a tidal datum?

MMLW stands for Mean Lower Low Water, which is the average height of the lower of the two low tides each day over a specific period. It is used as a reference point for measuring water levels and depths in nautical charts and tidal predictions.

What environmental impact does tidal energy have?

Tidal energy has a relatively low environmental impact compared to other sources of energy. It does not produce greenhouse gas emissions or air pollutants during operation. However, tidal energy devices can disrupt marine ecosystems, affect sediment transport, and potentially harm marine life if not properly planned and managed.

How high can the moon pull water?

The moon's gravitational pull causes tides in Earth's oceans, but the height of the tide depends on factors such as the location of the particular body of water, the shape of the coastline, and the depth of the water. Generally, tides can range from a few centimeters to several meters in height.

What is percentage of tidal power using in India?

As of now, tidal power does not play a significant role in India's energy mix. India's focus has primarily been on solar and wind energy for renewable energy sources. Tidal energy potential in India is being explored, but currently, its contribution to the country's energy generation is minimal.

Will tidal power create jobs?

Yes, tidal power projects have the potential to create jobs, particularly in the areas of engineering, construction, maintenance, and operation. These jobs can help support local economies and foster growth in the renewable energy sector.
