Explanation:

The answer is "Yes," as it will provide more fuel than a source of vitamins and minerals for him as carbohydrates. Whereas after carbohydrates supply energy, lipids were applied to long-term electricity. Obesity is caused by over intakes of carbohydrates and fats. They must therefore be given in the amount recommended. For its activity, the brain uses glucose. Nevertheless, he does not require sufficient fat since fat is difficult to absorb & fat may make him sound more tired. To recover rapidly, one should consume carbohydrates and meals rich in vitamins. Selection for fat in the form of nuts should be mainly.

Answer:

Matter is a substance that has inertia and occupies physical space. According to modern physics, matter consists of various types of particles, each with mass and size.Matter can exist in several states, also called phases. The three most common states are known as solid, liquid and gas.Matter is the Stuff Around You or Atoms and compounds are all made of very small parts of matter. Those atoms go on to build the things you see and touch every day. Matter is defined as anything that has mass and takes up space (it has volume).Solid ice, water and steam are few examples of matter touched in everyday life. Subatomic particles are also considered as matter.

Answer:

D. A negative externality.

Explanation:

Particulate pollution is a form of pollution that is responsible for the degradation of the environment.

Particulate matter is also referred to as particle pollution or atmospheric aerosol particles and it can be defined as a complex microscopic mixture of liquid droplets and solid particles that are suspended in air.

An externality is typically an unwarranted cost or benefit by a manufacturer or producer of goods and services that affects a third party.

In Economics, an externality could either be positive or negative depending on its effect on a third party.

A negative externality arises when the production or consumption of a finished product or service has negative impact (cost) on a third party.

In conclusion, air pollution is an example of a negative externality because it causes harm to a third party.

Answer:

Explanation:

The equation for acceleration is

[tex]a=\frac{v_f-v_0}{t}[/tex] where vf is the final velocity and v0 is the initial velocity. For us, the final velocity is 25 m/s and the initial is 0 because the train started from resting position. Filling in and solving for a:

[tex]a=\frac{25-0}{30.0}[/tex] so

a = .83 m/s/s

Answer:

Original Length = L1

Stretched length =L2

From

R = pl/A

R=Resistance

p=Resistivity

A=Cross-sectional Area

l= length of wire

We can see that Resistance is directly Proportional to Length... Meaning that Resistance Increases also as Length increases.

R1/L1 = R2/L2

From the question... The key to note is this sentence

"The Stretched length is TWICE the Original Length"

Meaning

L2 = 2L1 (So replace L2 as 2L1 when solving)

R1=20ohms

Let R2 = k

Applying the formula

20/L1 = k/2L1

kL1 = 20x 2 L1

KL1 = 40L1

L1 cancels on both sides

k=40ohms.

So As the length doubled... The Resistance did too

from 20ohms to 40ohms

Resistors are [tex]500\Omega[/tex] and [tex]2000\Omega[/tex]

Power supply [tex]V=60\ V[/tex]

Voltmeter internal resistance [tex]r=2000\ \Omega[/tex]

When it connected around [tex]500\Omega[/tex] resistance, effective resistance becomes

[tex]\Rightarrow \dfrac{1}{R}=\dfrac{1}{500}+\dfrac{1}{2000}\\\\\Rightarrow R=\dfrac{2000}{5}\\\\\Rightarrow R=400\ \Omega[/tex]

Total resistance in series [tex]R_{net}=2400\ \Omega[/tex]

Current in circuit

[tex]I=\dfrac{60}{2400}=\dfrac{1}{40}\ A[/tex]

Voltage around [tex]500\Omega[/tex] resistance is

[tex]V=\dfrac{1}{40}\times 400\\\\V=10\ V[/tex]

(B) when voltmeter is connected around [tex]2000\Omega[/tex]  resistor

Net resistance around it

[tex]\Rightarrow \dfrac{1}{R}=\dfrac{1}{2000}+\dfrac{1}{2000}\\\\\Rightarrow R=1000\ \Omega[/tex]

Total resistance [tex]R_{net}=1500\ \Omega[/tex]

Current in circuit

[tex]I=\dfrac{60}{1500}=\dfrac{1}{25}\ A[/tex]

Voltage around [tex]2000\Omega[/tex] resistor

[tex]V=\dfrac{1}{25}\times 1000\\\\V=40\ V[/tex]

Explanation:

Given that,

The mass of tyre, m = 6 kg

The velocity of the tyre, v = 3 m/s

We need to find the momentum of the tyre. We know that, the momentum of an object is equal to the product of mass and velocity. SO,

p = mv

[tex]p=6\ kg\times 3\ m/s\\\\=18\ kg-m/s[/tex]

So, the momentum of the tyre is equal to 18 kg-m/s.

So,

[tex]f=\dfrac{18}{12}\\\\f=1.5\ Hz[/tex]

So, the frequency of these water waves is equal to 1.5 Hz.

Answer:

Explanation:

Since we are looking at speed over a time unit, we have an acceleration graph. The definition of acceleration mathematically is:

[tex]a=\frac{v_f-v_0}{t}[/tex] (that's the change in velocity over the change in time). The slope of any line in this graph wil represent the acceleration. Slope is rise over run, or y over x. Therefore, if acceleration is velocity over time, then the y axis is the velocity axis and the x axis is the time axis. It makes perfect, beautiful sense!!

Answer:

Volume of CO2 at STP = 13.8 liter (Approx.)

Explanation:

Given:

Mass of CO2 = 27 gram

Find:

Volume of CO2 at STP

Computation;

We know that;

At STP, Volume of 1 mol of gas = 22.4 liter

Molar mass of CO2 = 44 g/mole

So,

Volume of CO2 at STP = [Mass of CO2 / Molar mass of CO2 ][22.4]

Volume of CO2 at STP = [27/44][22.4]

Volume of CO2 at STP = [0.6136][22.4]

Volume of CO2 at STP = 13.8 liter (Approx.)

Answer:

Calculate the mass of 6.022 × 1023 molecule of Calcium carbonate (CaCO3).

Solution —

Molar mass (Molecular mass in gram) of CaCO3 = 40+12+3×16 = 100 g

No. of moles of CaCO3

= No. of molecules/Avogadro constant

= 6.022 × 1023/ 6.022 × 1023

= 1 mole

Mass of CaCO3

= No. of moles × molar mass

= 1 × 100 g = 100 g.

Answer:

La entropía del vapor de mercurio cambia en 214.235 joules por Kelvin.

Explanation:

Por definición de entropía ([tex]S[/tex]), medida en joules por Kelvin, tenemos la siguiente expresión:

[tex]dS = \frac{\delta Q}{T}[/tex] (1)

Donde:

[tex]Q[/tex] - Ganancia de calor, en joules.

[tex]T[/tex] - Temperatura del sistema, en Kelvin.

Ampliamos (1) por la definición de calor latente:

[tex]dS = \frac{L_{v}}{T}\cdot dm[/tex] (1b)

Donde:

[tex]m[/tex] - Masa del sistema, en kilogramos.

[tex]L_{v}[/tex] - Calor latente de vaporización, en joules

Puesto que no existe cambio en la temperatura durante el proceso de vaporización, transformamos la expresión diferencial en expresión de diferencia, es decir:

[tex]\Delta S = \frac{\Delta m \cdot L_{v}}{T}[/tex]

Como vemos, el cambio de la entropía asociada al cambio de fase del mercurio es directamente proporcional a la masa del sistema. Si tenemos que [tex]m = 0.50\,kg[/tex],[tex]L_{v} = 2.7\times 10^{5}\,\frac{J}{kg}[/tex] and [tex]T = 630.15\,K[/tex], entonces el cambio de entropía es:

[tex]\Delta S = \frac{(0.50\,kg)\cdot \left(2.7\times 10^{5}\,\frac{J}{kg} \right)}{630.15\,K}[/tex]

[tex]\Delta S = 214.235 \,\frac{J}{K}[/tex]

La entropía del vapor de mercurio cambia en 214.235 joules por Kelvin.

Answer:

D. A nucleus of 2 protons and 2 neutrons.

Explanation:

A stable nucleus is one that do not disintegrate naturally, majorly due to the even number of its protons and neutrons. Thus they are not radioactive in nature.

From the given question, it would be observed that a nucleus of 2 protons and 2 neutrons would give a helium atom. And this is a stable atoms due to the magnetic number of the components of its nucleus.

Thus, the nuclear configuration that is most stable out of the given options is a nucleus of 2 protons and 2 neutrons. Option D.

Explanation:

We need to apply the conservation law of linear momentum to two dimensions:

Let [tex]p_{1}[/tex] = momentum of the 1st ball

[tex]p_{2}[/tex] = momentum of the 2nd ball

In the x-axis, the conservation law can be written as

[tex](p_{1} \cos \theta_{1})_{i} + (p_{2} \cos \theta_{2})_{i} = (p_{1} \cos \theta_{1})_{f} + (p_{2} \cos \theta_{2})_{f} [/tex]

or

[tex](m_{1}v_{1})_{i}= (m_{1}v_{1}\cos \theta_{1})_{f} + (m_{2}v_{2}\cos \theta_{2})_{f} [/tex]

Since we are dealing with identical balls, all the m terms cancel out so we are left with

[tex](v_{1})_{i} = (v_{1})_{f}\cos \theta_{1} + (v_{2})_{f}\cos \theta_{2}[/tex]

Putting in the numbers, we get

[tex]1.33 = (0.750) \cos(33.30) + (v_{2})_{f} \cos \theta_{2}[/tex]

[tex] = > (v_{2})_{f} \cos \theta_{2} = 0.703[/tex]

In the y-axis, there is no initial y-component of the momentum before the collision so we can write

[tex]0 = (v_{1}\sin \theta_{1})_{f} + (v_{2}\sin \theta_{2})_{f} [/tex]

or

[tex] = > (v_{2})_{f} \sin \theta_{2} = (0.750) \sin(33.30) = 0.412[/tex]

Taking the ratio of the sine equation to the cosine equation, we get

[tex] \frac{ \sin \theta _{2}}{ \cos \theta_{2} } = \tan \theta_{2} = \frac{0.412}{0.703} = 0.586[/tex]

or

[tex] \theta_{2} = { \tan}^{ - 1} (0.586) = 30.4[/tex]

Solving now for [tex](v_{2})_{f}[/tex],

[tex](v_{2})_{f} = \frac{0.412}{ \sin(30.4) } = 0.815 \: \frac{m}{s} [/tex]

Answer:

Speed = 300 m/s

Explanation:

Given the following data;

Wavelength = 10 m

To find the speed of the wave;

Mathematically, the speed of a wave is given by the formula:

[tex] Speed = wavelength * frequency [/tex]

Substituting into the formula, we have;

[tex] Speed = 10 * 30 [/tex]

Speed = 300 m/s
