Unlike charges attracting each other
There are huge losses in the transmission, production and usage of electricity and the reduction of these losses in order to save electricity is called as conservation of energy.
As per the statistics, there is loss of nearly 4% while the transmission of electricity. Like wise during production also, lot of electricity get wasted due to the inefficient material used. None of the production material nor the equipment used have 100% efficiency and thus there is always a possibility of energy wastage.
When it is said that the energy is wasted , it simply means that the energy production which should have been 100% as per calculation is not completely derived from the source due to the inefficient conversion process. For example, a turbine while rotating must convert 100 % of the water energy or water falling on it into electrical energy but the turbine is not able to do so as some of the water is lost or its energy is lost before conversion while going through the mechanical process.
The brainstem is the innermost region of the brain. Considered to be the "trunk" of the brain, the brainstem is the posterior region of the brain composed of three main parts: medulla oblongata, pons, and midbrain. It is a continuous structure connected to the spinal cord.
Answer:
B) Amplitudes
Explanation:
The equations of the electric and magnetic fields given are sinusoidal functions. he sine function varies between the value of -1 and 1 when is multiplied by a number A then varies from -A to A. In this case the variation goes from -E0 to E for the electric field and from -B0 to B0 for the magnetic field. Because the amplitude is half of the distance between the highest and the lowest value of the sinusoidal function. In the electric field is: E0-(-E0)/2=E0 and in the magnetic field B0-(-B0)/2=B0.
