Answer:

In a discharging battery or galvanic cell (diagram at right), the anode is the negative terminal because it is where conventional current flows into the cell.

Explanation

In the lab. construct two half cells, one a zinc half cell and the other a copper half cell.

The zinc metal electrode will more readily ionise to Zn^2+  ion , then the copper metal.

This is because in the reactivity series zinc is more reactive metal.

Hence

connecting the two half cells, the zinc cell is put on the left and the copper half cell on the right.

Connect a wire and voltmeters between the electrodes, and a salt bridge between the two metal ion solutions.

Since the zinc is on the left and loses its electrons more readily the electrons flow from the electrode through the wire and voltmeter to the copper electrode.  So the electrons flow from r

left to right.

The conventional eq'n is

Zn|Zn^2+||Cu^2+|Cu

The electrons move into the copper electrode combine with copper solution to form more copper metal, which deposits on the copper electrode.

In a battery (voltaic cell), conventional current flow in the direction from positive to negative.

Current is a flow of charges. it is denoted by i and expressed in ampere A.

Mathematically it is expressed as i = q/t, where q is the amount of charge and t is time. Current is nothing but amount of charges flown in the unit time in the electric wire. Charge is expressed in coulomb C and time in second s. hence coulomb per second (C/s) is ampere A. Charge on electron is 1.60217663 × 10⁻¹⁹ which is called as elementary charge.

There are two types of the current, Convectional current and non-conventional current.

Convectional current is the current flows from positive to negative. Non convectional current flows from negative to positive. Note that flow of electrons is from negative to positive.

Hence direction of flow of conventional current is from positive to negative.

Answer:

D

Explanation:

You can see the 1st Law thermodynamatic, that energy flow of thermo source.

Answer:

1) τ = I α    whereby the torque is provided by the angular acceleration

2)  L = 216 Kg m² / s

Explanation:

1) Let's start with Newton's second law

       F = m a

multiply by the arm or perpendicular distance

       F r = m a r

if the distance is not perpendicular a way of realizing the relations using the vector product

      τ = F r = F x r

the bold are vectors.  The angular and linear acceleration are related

       a = α r=

      τ = m (α r) r

      τ = (m r²) α

the inertia of the rotational motion is

        I = m r²

we substitute

       τ = I α

whereby the torque is provided by the angular acceleration.

As an example we have:

* a spinning disk

* a ball rotating in the air

* a pulley

2) The rotational momentum is

           L = I w

the moment of inertia of a rod that through its center

           I = m L²

we substitute

           L = m L² w

let's calculate

          L = 6 1.5 2 16

          L = 216 Kg m² / s

La cantidad de movimiento angular de la varilla uniforme es 18 kilogramos-metro cuadrado por segundo.

1) La relación entre el momento de torsión ([tex]M[/tex]), una variable cinética y relacionada con la aplicación de una fuerza externa cuya línea de proyección no cruza el centro de masa del objeto, y la aceleración angular ([tex]\alpha[/tex]), una variable cinemática, es la resistencia del cuerpo a rotar, la cual es función de su masa y su geometría, representada por la variable de momento de inercia.

A continuación, presentamos tres ejemplos del concepto:

2) Asumamos que la varilla uniforme es de masa constante, con una rotación a velocidad angular constante y con un centro de rotación localizado en el centro geométrico de la varilla. La cantidad de movimiento es expresada mediante la siguiente ecuación:

[tex]L = I\cdot \omega[/tex] (1)

Donde:

El momento de inercia de una varilla uniforme con centro de rotación en el centro queda expresado por la siguiente fórmula:

[tex]I = \frac{1}{12}\cdot m\cdot L^{2}[/tex] (2)

Donde:

Al aplicar (2) en (1), tenemos la expresión resultante:

[tex]L = \frac{1}{12} \cdot m\cdot L^{2}\cdot \omega[/tex] (3)

Si sabemos que [tex]m = 6\,kg[/tex], [tex]L = 1.5\,m[/tex] y [tex]\omega = 16\,\frac{rad}{s}[/tex], entonces la cantidad de movimiento angular es:

[tex]L = \frac{1}{12}\cdot (6\,kg)\cdot (1.5\,m)^{2}\cdot \left(16\,\frac{rad}{s} \right)[/tex]

[tex]L = 18\,\frac{kg\cdot m^{2}}{s}[/tex]

La cantidad de movimiento angular de la varilla uniforme es 18 kilogramos-metro cuadrado por segundo.

Answer:

[tex]6.3\ m/s^2[/tex]

Explanation:

Given that,

If the mass of a body is 15 kg and produced an 4.2 m/s², we need to find the acceleration if the mass is 10 kg and the same force is applied.

Force is given by :

F = ma

Since force is same

[tex]m_1a_1=m_2a_2\\\\a_2=\dfrac{m_1a_1}{m_2}\\\\a_2=\dfrac{15\times 4.2}{10}\\\\a=6.3\ m/s^2[/tex]

So, if the mass is 10 kg, acceleration is [tex]6.3\ m/s^2[/tex]

I'm pretty late to this but oh well. Well to start why are people homophobic in the first place? You might not understand as well but that is because me and you are growing up at a time and place where people are encouraged to be themselves and we're embracing people that are different than what is considered normal. Gay marriage was legalized literally in the US in 2015, 5 years ago. I come from Malaysia, one of the few countries where it's illegal to be gay and can cause a death penalty from what I've seen. Obviously I grew up in a place where gay and whatnot were a joke and is wrong. But we moved and I came to the US and my beliefs changes, it also helped that I was literally only 11 so I was more easier to change than adults. Majority of the world honestly, are not as open to the lgbtq+ community as a person in America might think. The belief that it's only a women and men probably stems from the fact that it's how u make babies. And if we know anything, society doesn't like things that are different. To stop people being homophobic you have to stop people from spreading the belief that it's wrong to be gay or bi. This is going to be hard and people really overestimate the world when it comes to change. Peoples belief won't be changed so quick just, change doesn't happen quick. It's going to be a long time and maybe even never, look at racism. We all exist together for so long but there's still racism though much less compared to back then. As long as people stop teaching that next generation, us, that being lgbtq+ is bad, it will decrease but it will take a long time. And as much as I agree we need it to be now, it won't and trying to force something will only cause more backlash. Just try to inform the people around you and understand change does not happen fast, it's slow, especially if it you want it to be permanent.

Answer:

yes Robert's kinetic energy will be twice as much

if Robert runs twice as fast, then his KE will be 8 times Mary's KE

Explanation:

Kinetic energy KE = [tex]\frac{1}{2}[/tex]m[tex]v^{2}[/tex]

for Robert KE =  [tex]\frac{1}{2}[/tex](2m)[tex]v^{2}[/tex] =  m[tex]v^{2}[/tex]

for Mary KE = [tex]\frac{1}{2}[/tex]m[tex]v^{2}[/tex]

If you divide Robert KE by Mary KE = m[tex]v^{2}[/tex] /  [tex]\frac{1}{2}[/tex]m[tex]v^{2}[/tex] = 2; yes Robert's kinetic energy will be twice as much

if Robert v is equal to 2v

for Robert KE =  [tex]\frac{1}{2}[/tex](2m)[tex](2v)^{2}[/tex] =  4m[tex]v^{2}[/tex]

for Mary KE = [tex]\frac{1}{2}[/tex]m[tex]v^{2}[/tex]

If you divide Robert new KE by Mary's KE = 4m[tex]v^{2}[/tex] /  [tex]\frac{1}{2}[/tex]m[tex]v^{2}[/tex] = 8, if Robert runs twice as fast, then his KE will be 8 times Mary's KE

Roberto has twice the mass his sister Mary has (see above) but runs at the same velocity as Mary, then his kinetic energy would be twice that of Mary, and the kinetic energy of Roberto would be 8 times when he runs twice as fast Mary.

Mechanical energy is the combination of all the energy in motion represented by total kinetic energy and the total stored energy in the system which is represented by total potential energy.

The kinetic energy is the body depends on the mass as well as the speed of the object and is given by the mathematical expression as follows

K.E = 1/2 × m × v²

When Roberto runs at the same speed as his sister Mary but has twice Mary's mass (see above), Roberto's kinetic energy is twice Mary's, and it is eight times higher when Roberto runs twice as quickly as Mary.

Answer:

Vf = 2000 [m/s]

Explanation:

To solve this problem we must use the following equation of kinematics.

[tex]v_{f} =v_{o}+a*t\\[/tex]

where:

Vf = final velocity [m/s]

Vo = initial velocity = 1200 [m/s]

a = acceleration = 4 [m/s]

t = 200 [s]

Vf = 1200 + (4*200)

Vf = 1200 + 800

Vf = 2000 [m/s]

The weight of the car on Earth is 19.6

Explanation:

The given parameters are;

The gravitational acceleration on the moon, [tex]a_{Moon}[/tex] = 1.6 m/s²

The gravitational acceleration on Earth, g = 9.8 m/s²

The weight of the car on the moon = 3.8 N

The weight of an object = The mass of the object, m × The gravitational acceleration acting on the object, g

The weight of the car = The mass of the car × The gravitational acceleration on the moon

∴ 3.8 N = The mass of the car × 1.6

The mass of the car = 3.8/1.6 = 2 kg

The weight of the car on Earth =The mass of the car × The gravitational acceleration on Earth, g

The weight of the car on Earth = 2 × 9.8 = 19.6

The weight of the car on Earth = 19.6.

The magnitude of a vector is the length of the vector. The magnitude of the vector a is denoted as ∥a∥. See the introduction to vectors for more about the magnitude of a vector.

Formulas for the magnitude of vectors in two and three dimensions in terms of their coordinates are derived in this page. For a two-dimensional vector a=(a1,a2), the formula for its magnitude is

∥a∥=a21+a22‾‾‾‾‾‾‾√.

For a three-dimensional vector a=(a1,a2,a3), the formula for its magnitude is

∥a∥=a21+a22+a23‾‾‾‾‾‾‾‾‾‾‾‾√.

The formula for the magnitude of a vector can be generalized to arbitrary dimensions. For example, if a=(a1,a2,a3,a4) is a four-dimensional vector, the formula for its magnitude is

∥a∥=a21+a22+a23+a24‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾√.

Answer:

The wavelength of the waves is approximately 0.12 m.

Explanation:

An electromagnetic waves are generated as a result of the interaction between electric and magnetic fields. They do not require material medium for their propagation, and travel at the same speed (i.e the speed of light).

The speed, frequency and wavelength of a wave are related by:

speed = frequency x wavelength

wavelength = [tex]\frac{speed}{frequency}[/tex]

Given: speed of the wave = 3 x [tex]10^{8}[/tex], frequency = 2.54 x [tex]10^{9}[/tex].

Thus,

wavelength = [tex]\frac{300000000}{2540000000}[/tex]

                    = 0.11811

                    ≅ 0.12

wavelength ≅ 0.12 m

Therefore, the wavelength of the waves is 0.12 m.
