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.

Quantity of charge = 0.5 * 17

Quantity of charge = 8.5 Coulombs

Answer:

Explanation:

This is the First Law of Thermodynamics that says that energy cannot be created nor destroyed. Which means, to us, that the ball has a specific amount of energy available to it, regardless of where it is in its travels, and this amount of energy will never be increased or decreased, that it will ust change its form. The Total Energy equation for this situation is

TE = PE + KE whih says that the total energy available to the system is equal to its Potential Energy plus its Kinetic Energy, and that Total Energy will never change. First we need to find the TE available. Looking at the first statement, we come into this problem and the ball is sitting still at the top of a hill. If the ball is sitting still, it has no Kinetic Energy, so all the energy is Potential. Therefore,

TE = PE + 0 and what we find here for the TE is the TE available throughout the trip. PE = mgh, so

TE = (20.0)(9.8)(100.0) I added in some sig dig but will still round to 2 because 1 does nothing for us.

TE = 2.0 × 10⁴ J. Now we move on to the next part of the problem, where the ball starts moving. The instant the ball starts moving, the PE starts to convert to KE, but as long as the ball still has the potential to fall to a lesser height, it also still has PE...long story short, it has both PE and KE at this point. And since TE = PE + KE, then

2.0 × 10⁴ = (20.0)(9.8)(10.0) + [tex]\frac{1}{2}(20.0)v^2[/tex] and we solve for v, simplifying some at first.

2.0 × 10⁴ = 2.0 × 10³ + 10.0v² and

[tex]v=\sqrt{\frac{2.0*10^4-2.0*10^3}{10.0} }[/tex] so, to 2 sig fig,

v = 42 m/s

Get to know how to do this; it will save your sanity!!

Answer:

g = 0.4 m/s²

Explanation:

Given the following data;

Height = 5 meters

Time = 5 seconds

To find the acceleration due to gravity (g) on the planet;

Mathematically, the maximum height of an object is given by the formula;

H = ½gt²

Where;

H is the height measured in meters.

g is the acceleration due to gravity.

t is time measured in seconds.

Substituting into the formula, we have;

5 = ½ * g * 5²

5 = 0.5 * g * 25

5 = 12.5 * g

g = 5/12.5

g = 0.4 m/s²

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:

The initial velocity of the pooper off the table is approximately 9.264 m/s

Explanation:

The mass of the popper, m = 0.1 kg

The height the popper reaches, h = 2.0 meters

The initial velocity of the popper, 'u', is given by the following kinematic relation;

v² = u² - 2·g·h

Where;

h = The height the popper reaches = 2.0 m

v = The final velocity of the popper at the height it reached = 0 m/s

u = The initial velocity of the pooper off the table

g = The acceleration du to gravity, g ≈ 9.81 m/s²

Plugging in the values gives;

0² = u² - 2 × 9.81 × 2.0

∴ u - √(2 × 9.81 × 2.0) ≈ 9.264

The initial velocity of the pooper off the table, u ≈ 9.264 m/s.

Answer:

Explanation:

We will use the equation F - f = ma, which is just a fancy way of stating Newton's 2nd Law. For us:

F = 5.20 to the right (+)

f = 3.29 to the left (-)

m = 1.05 kg. Therefore,

5.20 - 3.29 = 1.05a and

1.91 = 1.05a so

a = 1.82 m/s/s to the right

Explanation:

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:

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.

Explanation:

Gravitational potential energy is energy an object possesses because of its position in a gravitational field. ... Since the force required to lift it is equal to its weight, it follows that the gravitational potential energy is equal to its weight times the height to which it is lifted. PE = kg x 9.8 m/s2 x m = joules.

So, the PE is

3 x 9.8 x 4.5 = 132.3 J

Answer:

Option (2) is correct.

Explanation:

When two charges have equal charges they repel each other. On the other hand, if they have unequal charges they attract each other.

The force between the two protons in a helium nucleus is electrostatic charges and the force is repulsive in nature.

Also, there exists a strong nuclear force between charges.

So, a repulsive electrostatic force and an attractive strong nuclear force is the correct answer.

s = (0)(t) + (1/2)(5.77)(13²)

Distance cover in 13 seconds = 487.56 meter

Answer:

the total energy of the satellite is -2.0 x 10¹⁰ J

Explanation:

Given;

kinetic energy of the satellite, K.E = 2.0 x 10¹⁰ J

gravitational potential energy, P.E = -4 x 10¹⁰ J

The total mechanical energy of the satellite is calculated as follows;

M.E = K.E + P.E

M.E = 2.0 x 10¹⁰ J - 4 x 10¹⁰ J

M.E = -2.0 x 10¹⁰ J

Therefore, the total energy of the satellite is -2.0 x 10¹⁰ J

Answer:

    w = [tex]\frac{m}{ml^2 + I R^2 }[/tex]  v l

Explanation:

Let's form a system formed by the clay sphere and the rod, in this case the angular momentum is conserved

initial instant. Before the crash

          L₀ = m v l

Final moment. After the collision with the clay stuck to the rod

          L_f = I_{total} w

angular momentum is conserved

         L₀ = L_f

         m v l = I_total w

         w = [tex]\frac{m}{I_{total} }[/tex]  v l

the total moment of inertia is the sum of the moments of inertia of the two bodies

the moment of inertia of the rod is

        I_rod = I R²

        I_total = m l² + IR²

we substitute

          w = [tex]\frac{m}{ml^2 + I R^2 }[/tex]  v l

The angular speed f of the clay-rod system immediately after the collision

[tex]w=\dfrac{m}{ml^2+IR^2}VI[/tex]

Angular speed is defined as the rate of change of angular displacement,Angular Speed (ω) is the scalar measure of rotation rate. In one complete rotation, angular distance travelled is 2π and time is time period (T)

Let's form a system formed by the clay sphere and the rod, in this case the angular momentum is conserved

initial instant. Before the crash

[tex]L_o=mvl[/tex]

Final moment. After the collision with the clay stuck to the rod

[tex]L_o = L_f m v l = I_{total} w[/tex]

[tex]w=\dfrac{m}{I_{total}} Vl[/tex]

the total moment of inertia is the sum of the moments of inertia of the two bodies

the moment of inertia of the rod is

     [tex]I_rod = I R^2 I_{total} = m l^2 + IR^2[/tex]

we substitute

[tex]w=\dfrac{m}{ml^2+IR^2}VI[/tex]

Hence the angular speed f of the clay-rod system immediately after the collision

[tex]w=\dfrac{m}{ml^2+IR^2}VI[/tex]
