Is the production of electricity by magnetic field.
There are two types of generator which is <u>D</u><u>.</u><u>C</u><u> </u>generator . And A.C <em>g</em><em>e</em><em>n</em><em>e</em><em>r</em><em>a</em><em>t</em><em>o</em><em>r</em>
A.C gen consist of rectangular coil,brushes and permanent magnet
According to the external force mechanical energy used to rotate coil, due to magnetic flux produced by permanent magnet create induced current, this is to according to flemmings right hand rule of electromagnetic induction the rotating coil will produce current
I hope that will help.
Energy or heat can be calculated in terms of the mass, temperature, and specific heat of a substance. This is given by the equation:
U = mCpΔT = mCp(Tf-Ti)
where:
m = mass
Cp = specific heat
ΔT = temperature difference
For this problem, you need to get the specific heat of granite which can be found in reliable chemistry/engineering books or websites. According to Engineering Toolbox website, the Cp of granite is 790 J/(kg-°C).
U = 17 kg (790 J/(kg-°C)) (21-45) = - 322,320 Joules
*Note: the sign is negative because energy was released
Answer:
Creep
Explanation:
Creep is a type of deformation that occurs when continuous and long term mechanical stresses are being subjected to a material. Material deformation is observed even if the stresses are below the yield strength of the material, . The effect of creep is more pronounced if there is an application of heat.
In a study of turbine blades it has been shown that at the location where creep is present there was micro-structural degradation. In other places there was no micro-structural degradation.
The second choice ... starts with the word "both" ... is the correct statement.
