The velocity components expressed in m/s

1 answer:

3 0

The scalar absolute value (magnitude) of velocity is called speed, being a coherent derived unit whose quantity is measured in the SI (metric system) as metres per second (m/s or m⋅s−1). For example, "5 metres per second" is a scalar, whereas "5 metres per second east" is a vector.

Answer:

hello your question is incomplete attached below is the missing diagram to the question and the detailed solution

Answer : principal stresses : 0.82 MPa, -33.492 MPa

shear stress = 17.157 MPa

∅ = 9.09 ≈ 10°

Explanation:

The principal stress ( б1 ) = 0.82 MPa

( б2 ) = -33.492 MPa

The shear stress = 17.157 MPa

∅ = 9.09 ≈ 10°

A window‐mounted air‐conditioning unit (AC) removes energy by heat transfer from a room, and rejects energy by heat transfer to

Arada [10]

Solution :

Given :

The power of the air‐conditioning (AC) unit is , W = 0.434 kW

The coefficient of performance or the COP of the air‐conditioning (AC) unit is given by = 6.22

Therefore he heat removed is given by , $Q_H = 6.22 \times 0.434$

$Q_H = 2.7 \ kW$

Now if the electricity is valued at 0.10 dollar per kW hour, then the operating cost of the air conditioning unit in 24 hours is given by = 0.10 x 2.7 x 24

= 6.48

Therefore the operating cost = $ 6.48 for 24 hours.

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.
