Answer:
Total energy of the object = mgh. As it falls, its potential energy will change into kinetic energy. If v is the velocity of the object at a given instant, the kinetic energy = 1/2mv2.
Explanation:
The increasing order of the wavelength from left to right are as follows Gamma Rays < X-rays < UV rays < visible rays < infrared rays < microwaves < radio waves.
The electromagnetic spectrum consists of many waves which are made up of electric field and the magnetic field.
It is said that the electromagnetic wave behaves like particle as well as the wave.
The particle like pieces of the wave are called photons which contains the energy of the wave and the electromagnetic waves are primarily decided by the wavelength and the frequency of the wave.
The group of electromagnetic waves are known as electromagnetic spectrum.
The electromagnetic wave in the order of increasing wavelength are Gamma Rays < X-rays < UV rays < visible rays < infrared rays < microwaves < radio waves.

don't know the age sorry
Given :
Reem took a wire of length 10 cm. Her friend Nain took a wire of 5 cm of the same material and thickness both of them connected with wires as shown in the circuit given in figure. The current flowing in both the circuits is the same.
To Find :
Will the heat produced in both the cases be equal.
Solution :
Heat released is given by :
H = i²Rt
Here, R is resistance and is given by :
So,
Now, in the question every thing is constant except for the length of the wire and from above equation heat is directly proportional to the length of the wire.
So, heat produced by Reem's wire is more than Nain one.
Hence, this is the required solution.
