En un rio una Onda viaja con una velocidad de propagación de 50 m/s con una longitud de Onda de 40 metros. Hallar la frecuencia de la Onda.

Answers

Answer 1

Answer:

Frequencia = 1.25 Hz

Explanation:

Dados los siguientes datos;

Velocidad = 50 m/s Longitud de onda = 40 metros

Para encontrar la frecuencia de la onda;

Matemáticamente, la velocidad de una onda viene dada por la fórmula;

[tex] Velocidad = Longitud \; de \; onda * Frequencia [/tex]

Haciendo de la frecuencia el tema de la fórmula, tenemos;

[tex] Frequencia = \frac {Velocidad}{Longitud \; de \; onda} [/tex]

Sustituyendo en la fórmula, tenemos;

[tex] Frequencia = \frac {50}{40} [/tex]

Frequencia = 1.25 Hz

find the acceleration gained by a body in 6 seconds if its initial velocity is 30 meter/seconds and final velocity is 60/seconds meter and spammers stay away​

Answers

Answer:

Acceleration, a = 5 m/s²

Explanation:

Given the following data;

Initial velocity = 30 m/s

Final velocity = 60 m/s

Time = 6 seconds

To find the acceleration, we would use the first equation of motion;

V = U + at

Where;

V is the final velocity.

U is the initial velocity.

a is the acceleration.

t is the time measured in seconds.

Substituting into the equation, we have;

60 = 30 + a*6

60 - 30 = 6a

30 = 6a

Acceleration, a = 30/6

Acceleration, a = 5 m/s²

Raquel establece que la rapidez del sonido en el aire en un día es de 346 m/s . Días después hace la misma medición obteniendo una rapidez de 340 m/ s . ¿Cuál será la temperatura del aire en cada día?

Answers

Answer:

La ecuación para la velodiad del sonido en aire esta dada por:

[tex]v = \sqrt{ \frac{\gamma*R*T}{M} }[/tex]

Resolviendo esto para T, obtenemos:

[tex]T = v^2*(\frac{M}{\gamma*R} )[/tex]

donde:

T = temperatura del aire en grados Kelvin

γ = constante adiabatica = 1.4

R = constante del gas ideal =

M = masa molar del aire = 29*10^(-3) kg/mol

Si sabemos que el primer día la velocidad es 346 m/s, tenemos:

v = 346 m/s

Ahora podemos reemplazar todos esos valores en la ecuación para T, y asi obtener:

[tex]T = (346m/s)^2*(\frac{29*10^{-3}kg/mol}{1.4* 8.31 J/mol*K} ) = 298.42 K[/tex]

Para el segundo día la velocidad es 340 m/s, entonces ese día la temperatura va a ser:

[tex]T = (340m/s)^2*(\frac{29*10^{-3}kg/mol}{1.4* 8.31 J/mol*K} ) = 288.16 K[/tex]

energy and by how much (2)

Answers

Answer:

the green ball has 4J more energy

Explanation:

The kinetic energy is given by the formula

K = 0.5 m v^2

the kinetic energy of the red ball:

K(red) = 0.5*10*3^2= 45J

of the green ball:

K(green)=0.5*8*3.5^2 = 49J

therefore the green ball has more energy by 4 Joules

How is the force useful to us? ​

speed= 120s

distance= 8km

8km/120s=0.0666km/sec

0.0666km covered in 1 sec

3,600 seconds- 1km/hr

2. A student is pulling a 11.0 kg sled along flat ground. The students 30.0 kg sister then sits in the sled. The student then applies a 430 N force at an angle of 35° N of E. If the force of friction is 180 N, what is the acceleration of the sister sitting in the sled. (Ensure you draw a free body diagram.)

Answers

Answer:

Explanation:

The equation for this is

F - f = ma

The thing that gets strange here is that, because the student is pulling his sister on the sled with the rope at an angle, some of his efforts are being wasted. The sled is only going to move forward (horizontally), so the vertical component of that force is useless. He's not actually pulling horizontally with that much force; we have to figure out how much using the following equation:

[tex]F=430cos35[/tex] to get that

F = 352 N

Everything else falls into place quite easily into the equation now:

352 - 180 = 41a and

172 = 41a so

a = 4.2 m/s/s

Give a general description of how winds form

Answers

Answer:

Wind comes from pressure and temperature differences.

Explanation:

Have you ever opened a window on a hot day to let a breeze in? What is happening is a rush of air to balance out temperatures. This goal for uniformity is why ice melts in a glass of warm coffee and air rushes out of a balloon.

Answer:

Wind forms when the sun heats one part of the atmosphere differently than another part. This causes expansion of warmer air, making less pressure where it is warm than where it is cooler. Air always moves from high pressure to lower pressure, and this movement of air is wind.

(Hint: Does V go up or down when you go
from B to A?) (Unit = V)

Answers

Answer:

ΔV = 1139.3 V = 1.139 KV (+ve sign shows V goes up)

Explanation:

The potential difference while moving from point A to Point B is given as follows:

[tex]\Delta V = V_B-V_A[/tex]

where,

ΔV = potential difference from A to B = ?

[tex]V_A[/tex] = Potential at point A = [tex]\frac{kq}{r_A}[/tex]

[tex]V_B[/tex] = Potential at point B = [tex]\frac{kq}{r_B}[/tex]

Therefore,

[tex]\Delta V = \frac{kq}{r_B}-\frac{kq}{r_A}\\\\\Delta V = kq(\frac{1}{r_B}-\frac{1}{r_A})[/tex]

where,

k = Colomb's Constant = 9 x 10⁹ N.m²/C²

q = magnitude of charge = 4.88 x 10⁻⁸ C

[tex]r_A[/tex] = distance of point A from charge = 1.36 m

[tex]r_B[/tex] = distance of point B from charge = 0.538 m

Therefore,

[tex]\Delta V = (9\ x\ 10^9\ N.m^2/C^2)(4.88\ x\ 10^{-8}\ C)(\frac{1}{0.538\ m}-\frac{1}{1.36\ m})\\\\\Delta V = (439.2 N.m^2/C)(2.59\ /m)[/tex]

ΔV = 1139.3 V = 1.139 KV (+ve sign shows V goes up)

The answer is 492.87.

What efforts are made to bring uniformity in measurement​

Answers

Answer: The use of S I Unit brings uniformity in measurements.

Explanation:

The S I unit is the international system of units which are used to express the magnitudes or quantities of important natural phenomena. It is used universally as a standard for measurements thereby creating an avenue for uniformity in measurements. The base units that makes up the SI unit are:

--> Length: this is measured in meters (m)

--> Time: this is measured in seconds (s)

--> Mass: this is measured in kilogram (kg)

--> Temperature: this is measured in Kelvin (k)

--> Electric current: this is measured in ampere (A).

--> Amount of substance: this is measured in mole

--> Luminous intensity: this is measured in candela (cd)

These units are used as the standard to make our judgement of measurement more reliable and accurate. And since there is only one basic unit for each quantity (example length which is measured in meters) there is no need for further conversions.

Calculate the maximum absolute uncertainty for R if:

R = 9A / B
A = 32 +/- 2 seconds
B = 11 +/- 3 seconds

1 second


0.33 seconds


9 seconds


2 seconds


6 seconds

Answers

Answer:

ΔR = 9 s

Explanation:

To calculate the propagation of the uncertainty or absolute error, the variation with each parameter must be calculated and the but of the cases must be found, which is done by taking the absolute value

           

The given expression is      R = 2A / B

the uncertainty is                 ΔR = | [tex]\frac{dR}{dA}[/tex] | ΔA + | [tex]\frac{ dR}{dB}[/tex] | ΔB

we look for the derivatives

     [tex]\frac{dR}{dA}[/tex] = 9 / B

     [tex]\frac{dR}{dB}[/tex] = 9A ( [tex]- \frac{1}{B^2 }[/tex] )

we substitute

     ΔR = [tex]\frac{9}{B}[/tex]  ΔA + [tex]\frac{9A}{B^2}[/tex]  ΔB

the values ​​are

     ΔA = 2 s

     ΔB = 3 s

 

     ΔR = [tex]\frac{9}{11}[/tex]   2 + [tex]\frac{9 \ 32}{11^2 }[/tex]  3

     ΔR = 1.636 + 7.14

     ΔR = 8,776 s

the absolute error must be given with a significant figure

     ΔR = 9 s
