5. What things would settle in pond water, making it turn to land (terrestrial) succession?

Answer:

The train will have a greater impact than the bike

The train will have a bigger net force than the bike, so the acceleration of the train will be slower than the bike. In order to achieve the same acceleration, the train requires a bigger net force.

Under the Big Top elephant, Ella (2500 kg), is attracted to Phant, the 3,000 kg elephant. They are separated by 8

See the attached diagram for reference and free body diagrams. The acceleration a of each body will be the same since each connecting string is in tension.

By Newton's second law, we have

• net force on the train:

- - horizontal

[tex]\sum F = F - F_{k,T} - T_1 = m_Ta[/tex]

(where F = 12 N)

- - vertical

[tex]\sum F = N_T - m_Tg = 0[/tex]

• net force on wagon 1:

- - horizontal

[tex]\sum F = T_1 - T_2 - F_{k,1} = m_1a[/tex]

- - vertical

[tex]\sum F = N_1 - m_1g = 0[/tex]

• net force on wagon 2:

- - horizontal

[tex]\sum F = T_2 - F_{k,2} = m_2a[/tex]

- - vertical

[tex]\sum F = N_2 - m_2g = 0[/tex]

We want to determine T₂, the tension in the string connecting the two wagons.

For each body, the corresponding normal force has magnitude

N = mg

where m is the respective mass, and the kinetic friction has magnitude

Friction = 0.05 N = 0.05mg

So if µ = 0.05, then the frictional force on each body is

[tex]F_{k,T} = 0.05 (2.7\,\mathrm{ kg}) g = 1.323\,\mathrm N[/tex]

[tex]F_{k,1} = 0.05 (1.8\,\mathrm{ kg}) g = 0.882\,\mathrm N[/tex]

[tex]F_{k,2} = 0.05 (1.0\,\mathrm{ kg}) g = 0.49\,\mathrm N[/tex]

which leaves us with the system of equations,

[1] … 12 N - 1.323 N - T₁ = (2.7 kg) a

[2] … T₁ - T₂ - 0.882 N = (1.8 kg) a

[3] … T₂ - 0.49 N = (1.0 kg) a

Adding [1] and [2] eliminates T₁ :

(12 N - 1.323 N - T₁) + (T₁ - T₂ - 0.882 N) = (2.7 kg) a + (1.8 kg) a

[4] … 9.795 N - T₂ = (4.5 kg) a

Divide through both sides of [3] by 1.0 kg to solve for a :

a = (T₂ - 0.49 N) / (1.0 kg)

Substitute this into [4] and solve for T₂ :

9.795 N - T₂ = (4.5 kg) (T₂ - 0.49 N) / (1.0 kg)

(9.795 N - T₂) (1.0 kg) = (4.5 kg) (T₂ - 0.49 N)

9.795 N - T₂ = 4.5 T₂ - 2.205 N

12 N = 5.5 T₂

T₂ = (12 N) / 5.5 ≈ 2.1818 N ≈ 2.2 N

During photosynthesis solar energy is converted into chemical energy

Explanation:

During photosynthesis solar energy is converted into chemical energy in the form of energy rich bond of ATP molecule.

ATP (Adenosine triphosphate) and ADP (Adenosine diphosphate) molecules are termed currency of energy. ADP molecule is converted into ATP molecules, whenever energy is available in certain exothermic reactions of metabolism.

ATP molecules are store- house of energy. ATP molecule is broken down into ADP molecule in presence of enzyme ATPase, releasing energy whenever energy is required.

The synthesis of ATP molecules, utilizing solar energy during photosynthesis, is termed photo-phosphorylation.

These ATP molecules produced during light reaction of photosynthesis are utilized in dark reaction of photosynthesis (Calvin cycle).

ATP molecules synthesized during photo-phosphorylation may also be used in other metabolic reactions.

Photo-phosphorylation is of 2 types, i.e. Cyclic and Non-cyclic photo-phosphorylation.

Chlorophyll molecules entrap solar energy . There are 2 types of photo-systems in chlorophyll. These are photo-system -I and photo-system-II .

The electrons of chlorophyll molecule of photo-system I get excited which pass through series of electron carriers in electron transport system arranged in the order of decreasing energy level.

During the passage of electrons from carriers of higher energy level to the carriers of lower energy level, the energy is lost which is utilized for converting ADP molecule into ATP molecule.

Photo-system I is concerned with light reaction of photosynthesis only, constituting cyclic photo-phosphorylation.

The electron transport during Photo-system II results in the synthesis of NADPH2 in presence of enzyme NADP reductase. NADPH2 is used in reduction reaction of Calvin cycle.

Both Photo-systems participate in non-cyclic photo-phosphorylation that results in the synthesis of NADPH2 in addition to the synthesis of ATP molecules.

Explanation:

Un tren de alta velocidad (TAV) o tren bala es aquel que alcanza velocidades iguales o superiores a 200 km/h. La energía que tiene el tren en su recorrido habitual es

A. Cinética, debido a que existen trenes elevados los cuales poseen altura y la altura está asociada con la energía cinética.

B. Cinética, debido a que esta energía está asociada con la velocidad que posee el tren.

C. Rápida, porque la energía cinética es sinónimo de rápido.

D. Potencial, debido a la potencia que tiene el tren para moverse.

Solution:

La energía cinética es la energía contenida en un objeto en movimiento. La energía cinética se puede definir como la cantidad de energía necesaria para que un objeto se acelere desde el reposo hasta su velocidad final.

La energía cinética (KE) viene dada por:

KE = (1/2) * masa * velocidad²

Podemos ver que la energía cinética depende de la masa del objeto y la velocidad del objeto.

El tren de alta velocidad posee energía cinética debido a la velocidad del tren.

Explanation:

Energy is transferred from the sun to Earth via electromagnetic waves, or radiation. Most of the energy that passes through the upper atmosphere and reaches Earth's surface is in two forms, visible and infrared light. ... Once energy has been absorbed by the Earth system, it is transformed and transferred

The flow of energy when converted into the earth system is because of the transformation of energy.

The energy should be transferred from the sun to earth through electromagnetic waves, or radiation.

Many of the energy should be passed via the upper atmosphere and then reached the surface of the earth in two forms i.e. visible and infrared light.

In the case when the energy should be absorbed so it should be transformed and transferred.

Answer:

When you toss a rolled up sock across the room, it travels faster as it becomes round and has more weight added on it and this causes the sock to travel in the direction you wish and this gives you a high chance of the sock going straight into the laundry basket, no matter how far away you are.

On the other hand, throwing a sock without rolling it up will cause the sock to just flat down as you throw it. It will travel at a low speed because it has no weight on it since it is flat, and if you try to throw it, it will atleast land 21 cm away from you. About a 0% chance of it getting in the basket.

Answer:

0 Joules.

Explanation:

Given the following data;

Mass = 80kg

Height = 10m

Gravitational potential energy (GPE) is an energy possessed by an object or body due to its position above the earth.

Mathematically, gravitational potential energy is given by the formula;

[tex] G.P.E = mgh[/tex]

Where;

G.P.E represents potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per seconds square.

h represents the height measured in meters.

We know that acceleration due to gravity is equal to 9.8m/s²

But since we're determining the gravitational potential energy just before the driver jump, the height would be zero (0) meters.

Gravitational potential energy= mgh

Gravitational potential energy = 80*9.8*0

Gravitational potential energy = 0 Joules.

This ultimately implies that, if an object or body hasn't moved (jumped) from its reference point, its gravitational potential energy would be equal to zero.

Answer:

a. 4.99 × 10⁻⁴ N b. 1.46 × 10⁻³ N c. 4.83 nC

Explanation:

(a) Find the magnitude of the electric force acting on each ball.

The tension in the string, T is resolved into horizontal and vertical components Tsin20° and Tcos20° respectively, since the string makes an angle of 20° with the vertical.

Let F = electric force and W = mg be the weight of the ball where m = mass of ball = 0.14 g = 0.14 × 10⁻³ kg and g = acceleration due to gravity = 9.8 m/s²

The electric force acts in the opposite direction to the horizontal component of the tension in each string. Since the masses are in equilibrium,

Tsin20° = F (1)

Also, the weight of the ball acts downwards, opposite to the direction of the vertical component of the tension in the string. Since the masses are in equilibrium,

Tcos20° = W = mg

Tcos20° = mg (2)

Dividing (1) by (2), we have

Tsin20°/Tcos20° = F/mg

tan20° = F/mg

F = mgtan20°

So, F = 0.14 × 10⁻³ kg × 9.8 m/s²× tan20°

F = 0.4994 × 10⁻³ N

F = 4.994 × 10⁻⁴ N

F ≅ 4.99 × 10⁻⁴ N

(b) Find the tension in each of the threads.

Since  Tsin20° = F

T = F/sin20°

=  4.99 × 10⁻⁴ N/sin20°

= 4.99 × 10⁻⁴ N/0.3420

= 14.59 × 10⁻⁴ N

= 1.459 × 10⁻³ N

≅ 1.46 × 10⁻³ N

(c) Find the magnitude of the charge on the balls.

From Coulomb's law, the electric force between the masses of charge q and separated by a distance r = 2.05 cm = 2.05 × 10⁻² m

F = kq²/r² where k = 9.0 × 10⁹ Nm²/C²

q² = Fr²/k

q = √(Fr²/k)

q = [√(F/k)]r

Thus,  

q = [√(F/k)]r

q = [√( 4.99 × 10⁻⁴ N/9.0 × 10⁹ Nm²/C²)]2.05 × 10⁻² m

q = [√(0.5544 × 10⁻¹³ C²/m²)]2.05 × 10⁻² m

q = [√(5.544 × 10⁻¹⁴ C²/m²)]2.05 × 10⁻² m

q = [2.355 × 10⁻⁷ C/m]2.05 × 10⁻² m

q = 4.83 × 10⁻⁹ C

q = 4.83 nC

Let's say the force of gravity betwen you and the Earth (your "weight") is 100 pounds.

Then the force of gravity between you and a 10-pound bowling ball (sitting on the table 3-ft away from you) is about 0.000 000 049 of an ounce !

It's there, but it's too small for you to feel.

And it's not strong enough for the pencil or the bowling ball to jump up off the table, fly through the air, and stick to you.
