Question

What is meant by electrical equivalent of heat. (define )

What is electrical energy and what is thermal energy (explain with equations)

Answer #1

as per your requirements solved this question

What is heat? How is heat different from temperature, from
thermal energy? How is heat energy from system to system? Be sure
to include a unique example.

(i) Define what is meant by a functional in formulating
variational principles for dynamical systems.
(ii) State and explain Hamilton’s principle of least action and
give a brief discussion of how it leads to Lagrange’s equations (a
full derivation is not required).

lily's hairdryer converts 30j of electrical energy into heat,
10j into sound and 60j into kinetic energy. how efficient is
it?

which energy transformation occurs at a coal fired electrical
power plant?
1) heat is completely transformed into mechanical energy,
which is then converted to electricity
2) mechanical energy is completely transformed into heat,
which is then converted into electricity
3) electricity is completely converted into mechanical energy
and heat
4) heat is partially transformed into mechanical energy which
is then converted to electricity

. Define what is meant to be an “officer of an enterprise and
explain their responsibilities with regards to health and safety of
their workforce as well as their other responsibilities to the
enterprise.

Define what is meant by degree of freedom

5. Strontium-90 is to be used as a heat source for
generating electrical energy in a satellite. (a) How much of 90Sr
activity is required to generate 50 W of electric power if the
conversion efficiency from heat to electricity is 30%? (b) Weight
of the isotopic heat source is an important factor in design of the
power source. If weight is to be kept at a minimum and if the
source is to generate 50 W after 1 year...

Define what is meant by reuse and explain the three basic
steps involved in software reuse? (Abstraction, storage, and
recontextualization)

A
technician measures the specific heat capacity of an unidentified
liquid by immersing an electrical resistor in it. Electrical energy
is converted to heat, which is then transferred to the liquid for
124s at a constant rate of 65.3 W. The mass of the liquid is .779
kg and it’s temperature increases from 18.62 C to 22.51 C. A) find
the average specific heat of the liquid in this temperature range.
Assume that negligible heat is transferred to the container...

Logit Models causes a problem for inference in Maximum Likelihood
estimation?
