Define Inertia.​

Answer:

400J

Explanation:

The work done by the force on the object is 80 J.

The work is defined by the product of force and displacement. Its unit of measurement is joule. And the formula is,

Work = Force ×Displacement

Or mathematically it is W = F.d

     [tex]F = 20N , d = 4m\\[/tex]

       W = 20 × 4

       W = 80 J

Hence the work done by the force is 80J.

Answer:

1300 m/s

Explanation:

Applying,

v = λf/2............... Equation 1

Where v = velocity or speed of wave, f = frequency of wave, λ = wavelength of wave.

From the question,

Given: f = 325 Hz, λ = (12×2/3) = 8 m

Substitute these values into equation 2

v = 325(8)/2

v = 1300 m/s.

Hence the standing wave speed is 1300 m/s

The right option is 1300 m/s

Answer:

See the answer below

Explanation:

Acceleration due to gravity (g) is the accelerational force experienced by a body as a result of the influence of the earth's gravitational force. It is a vector quantity, that is, it has both magnitude and direction.

The acceleration due to gravity is inversely proportional to the square of the radius of the earth. Hence, g at the equatorial region is slightly lesser (9.780 m/s2) than that of the polar regions (9.832 m/s2) of the earth because the earth bulges at the equator leading to a higher radius than at the poles.  

Answer:

Velocidad final, V = 40 m/s

Explanation:

Dados los siguientes datos;

Aceleración = 5 m/s²

Velocidad inicial = 0 m/s (ya que comienza desde el reposo)

Tiempo = 8 segundos

Para encontrar la velocidad final, usaríamos la primera ecuación de movimiento;

[tex] V = U + at[/tex]

Dónde;

Sustituyendo en la fórmula, tenemos;

[tex] V = 0 + 5*8 [/tex]

[tex] V = 0 + 40 [/tex]

[tex] V = 40 [/tex]

Velocidad final, V = 40 m/s

Answer: Artificial Selection

Explanation: Artificial Selection is described as the identification of desirable traits in both plants and animals, then enhance them, so that those traits can be manifested in future generations.

This is the scope behind cross breeding of plants and animals and this have largely been used in agricultural sector to improve input (such as disease-resistant seeds) and other biotechnological settings.

Darwin's described artificial selection as the human form of natural selection.

Answer:

Nitric acid, also known as aqua fortis and spirit of niter, is a highly corrosive mineral acid. The pure compound is colorless, but older samples tend to acquire a yellow cast due to decomposition into oxides of nitrogen and water. Most commercially available nitric acid has a concentration of 68% in water.

Explanation:

Good morning...

Nitric acid production is mainly driven by fertilizer industry. Nitric acid is used in the production of ammonium nitrate and calcium ammonium nitrate which find applications as fertilizers.

Potential difference is measured in joules​ is true statement.

The difference in charge carriers' energy between two places in a circuit is known as the potential difference.

Voltage is another name for potential difference (p.d.), which is expressed in volts (V). When charge carriers move through electrical components in a circuit, energy is delivered to those parts. To determine the potential difference, we use a voltmeter (or voltage).

The amount of current multiplied by the resistance equals the potential difference, which is the same as voltage. One Coulomb of charge uses one Joule of energy to move between two points in a circuit, which is equal to a potential difference of one Volt.

Therefore, Potential difference is measured in joules​ is true statement.

Answer:

Protista

Explanation:

Taxonomy can be defined as the process of naming, classification and description of living organisms such as plants and animals. Thus, the biological classification of living organisms based on similarities or characteristics such as eyes, number of legs, etc., is generally referred to as taxonomy.

Basically, taxonomy helps scientist to have a good understanding and knowledge when studying various organisms.

Furthermore, the eight (8) biological classification (taxonomy) used for grouping and organizing organisms are; kingdom, domain, phylum, family, order, class, species and genus.

An organism that has only one cell, big and has a nucleus is most likely a member of Protista. Thus, a Protista such as euglena, paramecium, amoeba, etc., have a nucleus and are unicellular.

A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.

We are given:

Mass of load = 140 kg

Acceleration = 0.4 m/s² downward (from Q24)

24. Finding the tension in the cable:

Ma = Mg - T

where 'a' is the acceleration of the load and T is the tension in the cable

replacing the variables, we get:

(140)(0.4)  = (140)(9.8) - T

T = (140)(9.8) - (140)(0.4)

T = 1372 - 56

T = 1316N

25. Finding the distance covered when the load accelerates for 20 s:

in this case, the load will start from rest

so, initial velocity = 0 m/s

acceleration = 0.4 m/s²

from the second equation of motion:

s = ut + (1/2)at²

where s is the distance covered, u is the initial velocity and t is the time taken

s = (0)(20) + (1/2)(0.4)(20)²

s = 0 + 0.2*(400)

s = 80 m

here we didn't take the acceleration due to gravity of the mass into consideration because it is connected to the crane, which would act against any forces and since we are given that the total acceleration is 0.4 m/s², we will just assume that it's the final acceleration of the mass

Answer:

One simple explanation is that planets move, while stars remained fixed in the sky. You can observe a planet's orbit, but a star will stay in the same position.

Explanation:

Stars emit their own light due to thermonuclear fusion while planets have fixed orbits and they do not have their own light.

A star can be described as an astronomical body that possesses a light that causes it to reflect the light. A planet can be described as a fixed celestial body with a fixed path that spins on its own axis and reflects the light from an external source. Planets do not have an internal light source and receive light from external sources such as the Sun.

Stars have incredibly hot high temperatures while planets have relatively low temperatures. Stars produce their own light but planets are incapable of producing their own light.

Stars exhibit the unique effect of twinkling in the sky while planets do not exhibit the twinkling effect. The position of stars changes but can be seen only after a long time while planets in orbits change their positions constantly.

Answer:

Answer:

x = 1/2

Explanation:

5x/x + 2 = 3x/x + 1

do cross multiplication

(x + 2) * 3x = (x + 1) * 5x

3x^2 + 6x = 5x^2 + 5x

6x - 5x = 5x^2 - 3x^2

x = 2x^2

x/x^2 = 2

1/x = 2

1 = 2x

1/2 = x

Answer:

Supongo que queremos determinar la carga de la carga de prueba.

Sabemos que la fuerza culombiana entre dos cargas q₁ y q₂, separadas por una distancia R, está dada por:

[tex]F = k_c*\frac{|q_1*q_2|}{R^2}[/tex]

Aislandolo para una de las cargas, obtenemos:

[tex]\frac{F*R^2}{kc*|q_1|} =|q_2|[/tex]

En este caso sabemos:

fuerza atractiva, por lo que los signos de las cargas son opuestos.

q₁  = 5 mC

R = 35cm

F = 1.5 N

Kc = 9*10^9 N*m^2/C^2

Un primer paso, seria reescribir todos los valores en las mismas unidades.

Sabiendo que:

100cm = 1m

R = 35cm = (35/100) m = 0.35m

Y sabiendo que:

1mc = 1*10^(-6) C

Entonces:

q₁  = 5 mC = 5*1*10^(-6) C = 5*10^(-6) C

Ahora podemos reemplazar esos valores en la ecuación de la fuerza, para obtener el valor de la otra carga:

[tex]\frac{15N*(0.35m)^2}{(9*10^9 N*m^2/C^2)*5*10^{-6}C} =|q_2| = 4.08*10^{-5} C[/tex]

Y recordar que las cargas tienen signo opuesto, entonces la carga de la carga de prueba es:

q₂ = -4.08*10^-5 C
