Ans: C) 300,000 kilometers per second

Electromagnetic waves are created by the movement of charges. This results in the generation of electric and magnetic fields which oscillate in a direction perpendicular to each other.

Electromagnetic waves carry a certain wavelength, frequency and speed. The speed of such waves as they travel through space is equal to the speed of light (c) = 3*10⁸ m/s

since 1 km = 10³ m

speed, c = 1 km * 3*10⁸ ms-1/10³ m

                = 300, 000 km/s

mixer [17]

The medical understanding of death is related to the scientific approach, and the popular understanding is related to the inclusive spiritual and cultural approaches.

<h3 /><h3>What is death for science?</h3>

Death occurs when an individual's cardiorespiratory and brain functions cease due to some factor, thus ending his life.

Popular understanding, on the other hand, is aligned with scientific knowledge, but it is also encompassing cultural and religious teachings, which define topics not proven by science, such as life after death for example.

Therefore, death is a delicate topic for society, and spirituality is the basis found for greater emotional comfort in individuals who suffer significant losses of loved ones.

klio [65]
<h2>First stage of sleep Deprivation Subject </h2>

During the first stage of sleep deprivation, the subject is NREM which stands for non-rapid eye movement. In this condition, we are not sleeping in the depth. It can be said as dreamless sleep. On electro-encephalography recording, the brain waves are not fast so they have high voltage.

In this condition, the breathing, heart rate and blood pressure is low. The sleep is comparatively tranquil. NREM lasts for 90 minutes to 120 minutes. It accounts for about 75% of the normal sleep time. Rapid eye movements do not occur.
