A beaker is filled to the 500 ml mark with alcohol. What increase in volume (in ml) the beaker contain when the temperature chan
Tomtit [17]

Answer:

1.4 mL

Explanation:

Given that:

volume of alcohol V_0 = 500

Temperature change ΔT = (30° - 5°)C

=25° C

\beta_{ alcohol }= 1.12 \times 10^{-4} / ^0C

The increase in volume ΔV =  \alpha  \times  V_o \times \Delta T

= 500 \times 1.12 \times 10^{-4} / ^0 C\times   25^0 C

= 1.4 mL

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.
