How does a catapult incorporate technology?

1 answer:

6 0

I’m sure the answer is correct and it is below
“ A catapult works because energy can be converted from one type to another and transferred from one object to another. ... This energy is stored in the launching device as potential, or stored, energy. The catapult you are about to make uses elastic potential energy stored in a wooden stick as you bend it.”

Which of the following is not a relationship set between elements in a sketch

Svet_ta [14]

Answer:

The entity relationship (ER) data model has existed for over 35 years. It is well suited to data modelling for use with databases because it is fairly abstract and is easy to discuss and explain. ER models are readily translated to relations. ER models, also called an ER schema, are represented by ER diagrams.

What does WCS stand for? A. Western CAD System B. Worldwide Coordinate Sectors C. World Coordinate System D. Wrong CAD Settings

Ray Of Light [21]

Answer:

The correct answer is C. World Coordinate System

Explanation:

The World Coordinate System has to do with that coordinate system which is fixed in the activities of the CADing. There is a default system in which we can refer to them as soon as we want to manipulate the objects and add new elements.

Which of these energy technologies does not rely on a generator to produce electricity?

Phantasy [73]

<u>Wind turbine</u> does not rely on a generator to produce electricity. Thus, the correct option is option A.

<h3>What is a generator?</h3>

A generator is a device used in the production of electricity that transforms motive power, which is mechanical energy, or fuel-based power, which is chemical energy, into electric power for use in an external circuit.

Steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines, and even hand cranks can all be used to generate mechanical energy. Michael Faraday, a British scientist, created the Faraday disk, the first electromagnetic generator, in 1831. For electric power grids, generators supply almost all of the energy.

Photovoltaic and fuel cell powered generators, in addition to electromechanical designs, use solar power and hydrogen-based fuels, respectively, to produce electrical output.
