Can railway system work in a country without a constant energy power supply?

Yes. The engines would have to run off fossil fuels if
electricity is intermittent (This is still the standard, anyways)
and a communications system based around local power sources would
have to be used. It would be the job of the railway company to keep
its stations powered (i.e. fueled). If the railway company can
control power to its infastructure, it can run successfully.

Is energy flow involved in a change in state?
Yes, energy is simply a way for things to change, therefore it
is needed. Without energy flow (where energy is either gone or
constant) a substance will remain the same.

How does the body keep running without a constant food supply?
The body has reserves of energy it can spend when there is no
constant food intake. The cells can take energy from certain parts
of the body as glucose. These parts can be the liver or the
skeletal muscles, which particularly has glycogen (more difficult
to assimilate into energy).

Why do you have to conserve energy when infact the energy of this world is constant?
While the TOTAL amount of energy remains constant, on the other
hand, useful energy can, and will, be converted into unusable
energy.

Energy input remains constant and voltage remains the same in a curcit but current decreses what must be happening?
- If energy input is constant, then (E x I) is constant.
- If 'E' is constant, then 'I' must also be constant.
- Your ammeter must be failing.
Asked in Physics
Can potential energy be negative?
Yes. An object's potential energy is relative to an arbitrary
constant. Depending on the choice of that constant, the potential
energy can indeed be negative.

What is the base unit of Plancks constant?
Planck's constant relates the energy level of radiation due to
electrons moving from one energy level to another, by the formula
Energy = (Planck's constant) x (frequency of radiation). Therefore
the dimensions of Planck's constant are (energy)/(frequency) which
means Joules x seconds
In fact Planck's constant = 6.67 x 10-34 joule.seconds.
Asked in Physics, Chemistry, Energy
Why energy remains constant?
This is by the Principle of Conservation of Energy.
Energy cannot be created or destroyed, but can only be converted
from one form to another. Therefore, the amount of energy in a body
remains constant.

When velocity will be constant what will be the energy?
Kinetic energy will be constant, but total energy (KE+PE) might
not be. If the car, say, is climbing a hill at a steady speed, its
KE is constant, but the work done by the engine is being used to
increase PE.
Asked in Science
The total amount of energy in the universe remains constant as a result of what?
It is because of the law of conservation of mass and energy,
which states that the total amount of energy and mass in a closed
system remains constant. This is because of Noether's Theorem. It
states that some value in a symmetrical and closed system remains
constant. Because of this, the mass and energy content of the
universe remains constant as long as the laws of physics in it
remain constant.
Asked in Energy
Which idea is centeral to the law of conservation of energy?
The idea is that you can define a quantity, called "energy",
that remains constant over time. That is, if no energy escapes from
a system, and no energy comes into a system, the total amount of
energy will remain constant. Note that there are different types of
energy, and you can convert between the different types - but the
TOTAL amount remains constant.
