Explain the structure of the Electromagnetic Spectrum
Answer:
Explanation:
Electromagnetic spectrum, the entire distribution of electromagnetic radiation according to frequency or wavelength. Although all electromagnetic waves travel at the speed of light in a vacuum, they do so at a wide range of frequencies, wavelengths, and photon energies.
The structure of the Electromagnetic Spectrum is based on the arrangement of radiation in increasing order of their frequency and wavelength.
The electromagnetic spectrum consists of radiation of different frequencies and wavelength.
The range of the radiation in the electromagnetic spectrum in order of increasing frequency and decreasing wavelength is given as;
Radio waves, Microwaves, Infrared radiation, Visible light, Ultraviolet radiation,X-rays, and Gamma rays.Thus, the structure of the Electromagnetic Spectrum is based on the arrangement of radiation in increasing order of their frequency and wavelength.

The moon Ariel orbits Uranus at a distance of 1.91 x 108 m once every 2.52 days. Use that data to calculate the mass of Uranus. [?] x 10kg
Mu = 8.66 × 10^25 kg
Explanation:
centripetal force = gravitational force
[tex]m \frac{ {v}^{2} }{r} = (grav.const) \frac{m \times mu}{ {r}^{2} } [/tex]
where
m = mass of moon Ariel
mu = mass of Uranus
r = radius of Ariel's orbit
v = Ariel's velocity around Uranus
To find the velocity, we need to find the circumference of the no orbit and then divide it by the period (2.52 days):
circumference = 2πr = 2π×(1.91 × 10^8 m)
= 1.2 × 10^9 m
period = 2.52 days × (24 h/1 day)×(3600 s/1 hr)
= 2.18 × 10^5 s
v = (1.2 × 10^9 m)/(2.18 × 10^5 s)
= 5.5 × 10^3 m/s
(5.5 × 10^3 m/s)^2/(1.91 × 10^8 m) = (6.67 × 10^-11 m^3/kg-s^2)Mu/(1.91 × 10^8 m)^2
Solving Mu,
Mu = 8.66 × 10^25 kg
Which of the following football players have the same momentum?
Ted: mass = 60 kg, velocity = 2.0 m/s
Todd: mass = 80 kg, velocity = 1.7 m/s
Tom: mass = 90 kg, velocity = 1.5 m/s
Tim: mass = 100 kg, velocity = 1.2 m/s
a. Ted and Todd
b. Todd and Tim
c. Ted and Tim
d. None of the above.
Answer: Ted and Tim
Explanation:
The football players Ted and Tim have the same momentum, which is 120 kg m/s. Hence, option C is correct.
What is momentum?The momentum is the result of a particle's velocity and mass. Force and motion, meaning it has both magnitude and direction. According to Isaac Newton's second equation of motion, the force acting on a particle equals the time rate of increase of momentum.
The impulse, which is the product of the force and the intervals (the impulse), is equal to the difference in momentum, according to Newton's 2nd law, if a steady force operates on a particle for a specific amount of time. On the other hand, a particle's momentum is the amount of time needed for a consistent action to fight it to rest.
As per the given information in the question,
The momentum of Ted is,
p = 60 × 2 = 120 kg m/s
The momentum for Todd is,
p = 80 × 1.7 = 136 kg m/s.
The momentum of Tom is,
p = 90 × 1.5 = 135 kg m/s and,
The momentum for Tim is,
p = 100 × 1.2
p = 120 kg m/s.
After comparing the momentum of all the players, Ted and Tim have similar momentum.

Um ônibus está viajando numa estrada retilínea com a velocidade de 20 m/s. Vendo adiante um congestionamento no trânsito, o motorista aplica os freios durante 2,5 s e reduz a velocidade para 15 m/s. Supondo que a aceleração é constante durante o período de aplicação dos freios, calcule o seu valor, em m/s²?
Answer:
Aceleração = -2 m/s²
Explanation:
Dados os seguintes dados;
Velocidade inicial, u = 20 m/s
Velocidade final, v = 15 m/s
Tempo = 2.5 segundos
Para encontrar a aceleração;
Aceleração = (v - u)/t
Aceleração = (15 - 20)/2.5
Aceleração = -5/2.5
Aceleração = -2 m/s²
Nota: é negativo porque o freio aplicado está diminuindo a velocidade do carro, ou seja, a desaceleração.

Kevin bikes to the pizza place for lunch. He rides 1 km east, 3 km north, 4 km west, and finally 3 km south. What was his displacement?
Answer:
3kmExplanation:
To get the displacement, we will make use of the expression;
[tex]D = \sqrt{(\sum d_x)^2+(\sum d_y)^2}[/tex]
Taking the sum of the distances along the x;
dx = 1km - 4km
dx = -3km
Taking the sum of the distances along the y axis
dy = 3km - 3km
dy = 0km
Substitute into the formula above;
[tex]R = \sqrt{(-3)^2+(0)^2}\\R = \sqrt{9} \\R = 3km\\[/tex]
Hence his displacement is 3km

PLEASE HELP 15 POINTSexplain properties and importance of light and how it separates into colors
Answer:
It is not a property of light. It is your eyes and brain.
Specifically, the three kinds of cone cells in our eye that are sensitive to different ranges of the electromagnetic spectrum. The fact that there are three means that color is three dimensional, and is the reason the pure colors form a circle even though the spectrum of wavelengths is linear.
Visible light is part of the electromagnetic spectrum; light waves of different frequencies and wavelengths are distinguished as colors by the human eye. A prism can separate the colors of white light (dispersion) because different frequencies of light have different refractive indices for a given material.

Answer:
Resistance, R = 2.5 Ohms
Explanation:
Given the following data;
Voltage = 10 V
Current = 4 A
To find the resistance;
Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.
Mathematically, Ohm's law is given by the formula;
[tex] V = IR[/tex]
Where;
V represents voltage measured in voltage.
I represents current measured in amperes.
R represents resistance measured in ohms.
Making resistance, R the subject of formula, we have;
[tex] R = \frac {V}{I} [/tex]
Substituting into the equation, we have;
[tex] R = \frac {10}{4} [/tex]
Resistance, R = 2.5 Ohms
Therefore, the resistance of the resistor in the electrical circuit is 2.5 Ohms.
To understand the photoelectric effect physiciests should view light as having what type of properties?
Answer:
Particle
Explanation:
To understand photoelectric effect the physicists has to view light as a particle and not wave. The wave nature of the light could not explain the phenomenon of photoelectric effect.
Photoelectric effect is emission of electrons from a material when electromagnetic radiation(Light) is incident on it. These emitted electrons are called photoelectrons.
The explain this effect Einstein proposed that beam of light is can not be a wave propagating through space, but a swarm of discrete energy packets, called as photons.

4.- Una vagoneta de 1000 kg de peso parte del reposo en el punto 1 y desciende, sin rozamiento, por la vía indicada en la figura. A) Calcular la fuerza que la vía ejerce sobre la vagoneta en el punto 2, donde el radio de curvatura es de 6 m. B) Determinar el mínimo valor del radio de curvatura en el punto 3 para salvar dicho punto
Answer:
A) 49,050 N
B) 16 m
Explanation:
Question:
El dibujo de la pregunta se obtiene de un documento titulado "TRABAJO DIVERSO Y ENERGÍA" que se encuentra en línea y se presenta aquí.
La masa dada del vagón, m = 1,000 kg
La altura del punto en el que descansa el vagón, punto 1, h₁ = 12 m
A) El radio en el punto 2, el punto más bajo, R = 6 m
La fuerza, 'N', que la vía ejerce sobre el vagón en el punto 1 viene dada por la siguiente relación;
N = El peso del vagón + La fuerza de movimiento del vagón
∴ N = m × g + m × a
Dónde;
g = La aceleración debida a la gravedad ≈ 9,81 m / s²
a = La aceleración del vagón
Observamos que para el movimiento circular, la fuerza de movimiento del vagón, m × a = La fuerza centrípeta que actúa sobre el vagón = m × v² / R
∴ m × a = m × v² / R
Dónde;
v² = La velocidad del vagón en el punto 2 = 2 · g · h₁
Por lo tanto;
N = m × g + m × a = m × g + m × v² / R = m × g + m × 2 · g · h₁ / R
∴ N = 1000 × 9,81 + 1000 × 2 × 9,81 × 12/6 = 49,050
La fuerza que ejerce el vagón en el punto 2, N = 49,050 N
B) En el punto 3, tenemos;
N = m · g - m · a₃
La fuerza centrípeta en el punto 3, m · a₃ = m · v₃² / R₃
∴ La altura en el punto 3, h₃ = 4 m
El cuadrado de la velocidad en el punto 3, v₃² = 2 · g · (h₁ - h₃)
Para que el vagón esté seguro en el punto 3, la fuerza de la vía sobre el vagón, N = 0 para que el vagón permanezca en la vía actuando
Por lo tanto;
N = m · g - m · a₃ = 0
m · g = m · a₃ = m · v₃² / R₃ = m · (2 · g · (h₁ - h₃)) / R₃
∴ R₃ = (2 · g · (h₁ - h₃)) / g = (2 · (h₁ - h₃)) = 2 × (12 - 4) = 16
El radio de curvatura en el punto 3 para que el punto sea seguro es R₃ = 16 m.
