The rhythmic movement that carries energy through space or matter is called a Wave
The application is when human produce electromagnetic Radiation which now known as the Radio.
so the answer is d.
Answer:
Interneurons
Explanation:
An interneuron or integrative neuron is a central nervous system neuron, usually small and short axon, that interconnects with other neurons; but never with sensory receptors or muscle fibers, allowing more complex functions.
The interneuron, also called the association neuron, has the function of analyzing sensory information and storing part of it. It also acts on reflex acts, transforming a stimulus in response at the level of the spinal cord. They are located between sensory and motor neurons and are located in the upper nerve centers. Interneurons are multipolar neurons, which connect afferent neurons with efferent neurons in the neuronal or nerve tracts. In other words, they function as a communicational bridge, intercommunicating sensory neurons with motor neurons. Like motor cells, interneurons are only found in the central nervous system. In contrast to the peripheral nervous system, all CNS neurons appear to be interneurons, as they are in communication with many other neurons. However, the term "interneuron" refers to neurons that have axon and dendritic extensions of local extension and not distant, that is, short.
Answer:
Explanation:
Given that:
- mass of 1 skier,
- inclination of hill,
- length of inclined slope,
- time taken to reach the top of hill,
- coefficient of friction,
<em>Now, force normal to the inclined plane:</em>
<em>Frictional force:</em>
<em>The component of weight along the inclined plane:</em>
<em>Now the total force required along the inclination to move at the top of hill:</em>
<em>Hence the work done:</em>
<em>Now power:</em>
<u>So, power required for 30 such bodies:</u>
Answer:
Explanation:
Sun's dynamo means the process that produce Sun's magnetic field.
The mechanism inside a Sun acts like a generator that produces electric current and magnetic field.
Magnetic field with in the Sun are extended out and around. Magnetic field of lines get twisted due to rotation of Sun.
The material that flows inside the Sun plays an important role in Sun's dynamo. At surface the flow rate is about 20 m/s but as it moves towards equator, it becomes way too slow taking about 11 years of time.
Due to the this magnetic field, several sun spots are formed on the surface.
The number of sunspots keep on changing from minimum to maximum number resulting into change in the magnetic pole. In each cycle polarity get reversed hence the overall magnetic cycle has an interval of 22 years.
The average velocity is 12.5 meters per second
