Explanation:

Electron volt:

small unit of energy is known as electron Volt it is represented by eV

radiation:

energy and/or mass being ejected from a nucleus in the form of radiation.

Photon:

smallest amount of light is known as photon.

X-ray

radiation emitted from decelerated electrons are known as X-ray

Planck's constant :

planck's Constant is denoted by h=6.63 x 10^-34 js

Photoelectric effect:

light shining on a metal surface causes electrons to be emitted from the surface this phenomena is known as photoelectric effect.

Uncertainty principle:

According to uncertainty principal exact position and momentum of microscopic particle cannot be determined simultaneously.

De Broglie wave:

wave associated with moving matter is known as De Broglie wave.

best model for light includes both the wave theory and quantum theory

Quanta:

Light travel in the form of packets of energy and each packet of energy is known as photon or quanta.

What is the role of the nervous system?

zimovet [89]

The nervous system is responsible for sending, receiving, and interpreting information from all parts of the body. The nervous system monitors and coordinates internal organ function and responds to changes in the external environment. (The role) The central nervous system consists of the brain and the spinal cord. It is part of the overall nervous system that also includes a complex network of neurons, known as the peripheral nervous system. (Central nervous system)

if you run around a circle at 4.5 m/s and the circle has a radius of 7.7 m, what is your centripetal acceleration?

madreJ [45]

Answer:

Centripetal acceleration,

$a_{c} =2.63\ m/s^{2} }$

Explanation:

Centripetal acceleration:

Centripetal acceleration is the idea that any object moving in a circle, in something called circular motion, will have an acceleration vector pointed towards the center of that circle.

Centripetal means towards the center.

Examples of centripetal acceleration (acceleration pointing towards the center of rotation) include such situations as cars moving on the cicular part of the road.

An acceleration is a change in velocity.

Formula for Centripetal acceleration:

$a_{c} =\frac{(velocity)^{2} }{radius}$

Given here,

Velocity = 4.5 m/s

radius = 7.7 m

To Find :

$a_{c} = ?$

Solution:

We have,

$a_{c} =\frac{(velocity)^{2} }{radius}$

Substituting given value in it we get

$a_{c} =\frac{(4.5)^{2}}{7.7} \\\\a_{c} =\frac{20.25}{7.7}\\\\a_{c} =2.629\ m/s^{2} \\\\\therefore a_{c} =2.63\ m/s^{2$

Centripetal acceleration,

$a_{c} =2.63\ m/s^{2} }$
