According to the definition given, non-ionizing means using microwaves on a substance without causing charged ions to form by removing electrons from atoms.

<h3>What kind of energy exist?</h3>

The six primary forms of energy are chemical, electromechanical, photonic, muscular, geothermal, and nuclear fuel. Other research may focus on other forms including electrochemical, psychological, electromagnetic, and others.

<h3>Why is energy such a big deal?</h3>

Energy is a crucial part of our everyday life despite being just a basic human need. The buildings that people have constructed are heated and cooled by energy. Energy is needed to do things like lift your finger, get out of bed, or even merely go along the main corridor.

Describe the relationship between joules, meters, and newtons
Naily [24]
Newton is a unit of force. Joules is an amount of work which is equal to the force times distance, or newton meters. So the product of newtons and meters makes joules.

Why are you able to make someone on a swing have very large swings by only exerting very small forces on them?
Allisa [31]
Because almost all of the force is done by the weight of the person and the mechanism of the swing itself, when you push someone you only give them an increase in velocity, the acceleration comes from the weight at first and then from gravity when the person is coming down, which is why we bend our legs when coming down

What part of the electromagnetic spectrum that is necessary for the sense of sight in humans?
Alekssandra [29.7K]
<span>The part of the electromagnetic spectrum that is necessary for the sense of sight in humans is called visible light. This portion of the electromagnetic spectrum is composed of the various colors that the human eyes can distinguish. Each color has a corresponding wavelength. The human eyes can see wavelengths between 390-700 nm, and visible light ranges from 380-750 nm.</span>

Se lanza un cuerpo de 25 kg sobre un plano horizontal, con una velocidad de 20 m/s. Si el coeficiente de rozamiento es de 0,4 ca
Alex Ar [27]

Answer:

1. 98 N

2. 51.0 m

Explanation:

masa 25 kg

velocidad 20 m/s

coeficiente de rozamiento .4

<u>Fuerza de rozamiento:</u>

mu * N, where mu = coeficiente de rozamiento, N = fuerza normal

Calcula N:

F = ma = 25 * -9.8 = -245 N

F rozamiento = mu * N = .4 * -245 = -98 N

<u>Espacio que recorrerá:</u>

F rozamiento = ma

-98 = 25a

a = -3.92 de-aceleración de la fuerza

vf = 0 m/s

vf = at + vi

0 = -3.92t + 20

t = 5.10 seg

x = 1/2 at^2 + vi*t

  = 1/2 * -3.92 * 5.10^2 + 20*5.10

  = 51.0 m

An apple falls out of a tree from a height of 2.3 m What is the impact speed of the apple?
ivann1987 [24]

Answer:

6.72 m/s

Explanation:

recall that the equations of motion may be expressed as

v² = u² + 2as

where,

v = final velocity,

u = initial velocity = 0 m/s because it is stationary before it starts falling

a = acceleration (in this case because it is falling, it is the acceleration due to gravity = 9.81 m/s²)

s = distance traveled = 2.3m

in our case, if we neglect air resistance, then we simply substitute the known values above into the equation of motion.

v² = u² + 2as

v² = 0² + 2(9.81)(2.3)

v² = 45.126

v = √45.126

v = 6.72 m/s
