3 0

Answer:

Energy remain conserved while converting its form from one to another

Explanation:

As per the conservation of energy, energy always changes its form from one form to another and it is neither destroyed nor created. The total amount of energy always remains the same.

There are several forms of energy such as thermal energy, electrical energy, nuclear energy, electromagnetic energy, etc.

For example –  

During any chemical reaction, form of one chemical changes into another. In this process some amount of chemical energy remains conserved while the deficit in total starting energy is released as heat and light energy

Machine

We use various tools to perform different types of work in our daily life. The tools or simple devices used for making our work easier, faster and more convenient are simple machines.

Those tools or devices which make our work easier and convenient in the direction of the force is called simple machine.

Purpose of using simple machine

Simple machines are used to make our work easier in the following ways:

By multiplying force.

By changing the directions of force.

By transferring force from one point to another.

By increasing the rate of doing work.

In the two-slit experiment, for the condition of bright fringes, the value of m = +2 corresponds to a path difference of λ.
melisa1 [442]

Answer:

False

Explanation:

We know that if path difference is even multiple of wavelength then bright fringes are formed and if path difference is odd multiple of wavelength then dark fringes are formed .

For bright fringes

Path difference Δx = m λ

m = 0 , 2 , 4 , 6.......

If m = 2 then the path difference will be

Δx = 2 λ

therefore the above statement if false.

False
