Answer:

d

Explanation:

I did the test and got it right.

Based on the table, the statement that is true about the solubility of two substances in 100 milliliters is the solubility of hydrochloric acid increases as temperature increases. The correct option is d.

Solubility is a condition when the solute is fully mixed with the solvent and there is no difference between the molecules of solvent and the solutes.  The solubility of a substance is based on its molecules. If they are polar, then they can dissolve in numerous solvents.

The salt molecules are fully soluble in the water. The molecules which get dissolved are called the solute and the molecules that dissolve something within them, are called solvents.

Thus, the correct option is d, The solubility of hydrochloric acid increases as temperature increases.

Explanation:

Initial velocity is 25m/s i.e. u. Final velocity would be zero since the bus stopped. It is noted that the bus deccelartion of 4m/s, so the acceleration should be considered negative of 4m/s I.e. 4m/s. So using third law of motion i.e.

v^2 - u^2= 2as

(0)^2 - (25)^2= -2×4×s {Note here I used minus sign in acceleration}

-625 = -8×s

s=625 ÷ 8

s= 125 m

So bus would cover a distance of 125m before coming to rest.

Explanation:

these objects can flaot on water because theyre mass is not enough for the objects to sink.

Answer:

A)     E = 145.6 N / C , B)  y= 2,8 10-7 m with a downward direction

C) he shape of the trajectory of the two particles is to simulate a parabola,

D)     F_{e} /F_{g} = 10³⁴

Explanation:

A) For this exercise we use Newton's second law to find the acceleration of the electron, where the force is electric

           F = m a  

           - e E = m a

          a = - e E / m

with the field directed downward, the acceleration is in the vertical upward direction.

We look for how much the electron moves with kinematics, in the x direction there is no acceleration,

x axis (parallel to plates)

           x = v₀ t

           t = x / v₀

y axis (perpendicular to plates)

          y = y₀ + [tex]v_{oy}[/tex] t + ½ a t²

Let's take the zero of the system in the middle of the plates y₀ = 0, also the initial vertical velocity is zero (v_{oy} = 0) the width of the plate is known

          y = ½ a t²

we substitute

         y = ½ (e E /m)  (x / v₀)²

         y = ½ e x2 /m v₀²   E

we look for the electric field

        E = 2 m y v₀² / e x²

where to use this expression the length and width of the condenser must be known, suppose that the length is x = l = 1 cm = 1 10⁻² m and the width is y = 0.5 mm = 0.5 10⁻³ m

let's calculate

         E = 2  9.1 10⁻³¹ 0.5 10⁻³ (1.6 10⁶)² / (1.6 10⁻¹⁹ (1 10⁻²)²)

         E = 145.6 N / C

B) The electron is exchanged for a proton

Let's look for the vertical displacement, in this case as the proton has a positive charge it moves towards the bottom of the plates

          y = ½ e x² / m v₀² E

          y = ½ 1.6 10⁻¹⁹ 1 10⁻⁴ / (1.67 10⁻²⁷ (1.6 10⁶)²   145.6

          y = 28.4375 10⁻⁸ m

since the distance between the plates is 0.5 10-3 m, the proton passes the condensate because its deflection is very small

In summary, its displacement is y= 2,8 10-7 m and with a downward direction (the same direction of the electric field)

C) The shape of the trajectory of the two particles is to simulate a parabola, but one for having a negative charge (electron) the force is upwards and the other for having a positive charge (proton) the trajectory is downwards

D) The force of gravity

           [tex]F_{g}[/tex] = G m M / R²

electron

          Between the electron and the positive charges of the conducting plate

           F_{g}= 6.67 10⁻¹¹ 1.67 10⁻²⁷ 9.1 10⁻³¹ / (0.5 10⁻³)²

           F_{g} = 4.1 10⁻⁵¹ N

electric force

           F_{e} = -e E

           F_{e} = - 1.6 10⁻¹⁹ 145.6

           F_{e} = 2.3 10⁻¹⁷ N

let's look for the reason between these two forces

         F_{e} / F_{g} = 2.3 10⁻¹⁷ / 4.1 10⁻⁵¹

          F_{e} /F_{g} = 10³⁴

We see that the electric force is many orders of magnitude higher than the gravitational force.

Explanation:

The computation of the temperature measured by the thermometer is shown below:

Here is the thermometric scale list

(X - 0) ÷  C - 0 = (50 - 0) ÷ (100 - 0)  

X ÷ C = 50 ÷100  

X = C ÷ 2

Explanation:

normal force equals to the weight, which is equal to mass* gravitational force

Responder:

A. Ff = 300 N N = 784,8 N

Explicación:

Dado

Masa del cuerpo = 80 kg

Fuerza de movimiento Fm = 300N

Dado que el cuerpo no está acelerando, la fuerza de fricción (Ff) es igual a la fuerza de movimiento que actúa sobre el cuerpo, ya que la fuerza de fricción es una fuerza de oposición, es decir, Fm = Ff

Dado que Fm = 300N, Ff = 300N

La reacción normal que actúa en el cuerpo es igual al peso.

N = W = mg

g es la aceleración debida a la gravedad

g = 9,8 m / s

N = mg

N = 80 (9,81)

N = 784,8N

Por tanto, la fuerza normal que actúa sobre el cuerpo es 784,8 N

Answer:

C

Explanation:

Centripital force points to the center.

Using Newton's second law we can know the direction of the force that creates the uniform circular motion, the correct answer is:

C) The force must go towards the center of the circle

Newton's second law establishes a linear relationship between force and mass of the body and its relationship is

           F = m a

The bold letters indicate vectors, where F is the force, m the mass that is a scalar and the acceleration of the body

By analyzing this expression we see that the direction of the net force and the acceleration are the same,

The uniform circular motion is characterized by having a speed, speed modulus, constant therefore in the movement the acceleration vector must be perpendicular to the speed so that the change is of direction only.

The acceleration must go towards the center of the circle and by Newton's second law the net force must also go towards the center of the circle.

Let's analyze the different strengths of the graph

a and d) Tangential force to the circle

    False. This force changes the modulus of the velocity so the movement stops being uniform circular

e) outward perpendicular force

   False. This force changes the direction of the velocity and maintains its modulus, but the antiparallel to the acceleration which contradicts Newton's second law

b) Force at an angle.

   False. This force can be decomposed into two vectors, one parallel and the other perpendicular to the circle, the parallel vector combines the speed modulus and the movement is elliptical.

c) Force towards the center of the circle.

    True. This force changes the direction of the velocity and maintains its modulus, in addition, the acceleration is in the direction of the change in velocity, which is why the particle describes the circle.

Using Newton's second law we can know the direction of the force that creates the uniform circular motion having the correct answer is:

c) The force must go towards the center of the circle

Answer:

(a) The acceleration of the train and cars is approximately 0.304 m/s²

(b) The tension between the locomotive and the car connected to the locomotive is approximately 0.4166 N

Explanation:

The given parameter are;

The mass of the toy locomotive = 0.979 kg

The mass of one car = 0.952 kg

The mass of the other car = 0.419 kg

The total mass of the train locomotive and cars = 0.979 + 0.952 + 0.419 = 2.35 kg

The weight of the train locomotive and cars = 9.81 m/s² × 2.35 kg = 23.0535 N

The normal force of the train and cars = The weight of the train locomotive and cars = 23.0535 N

The coefficient of dynamic friction = The normal force × The coefficient of dynamic friction

The coefficient of dynamic friction = 23.0535 × 0.110 = 2.535885 N

The applied force = 3.25

The net force acting on the train locomotive and cars = 3.25 - 2.535885 0.714115 N

(a) Force = Mass × Acceleration

Acceleration = Force/Mass

∴ The acceleration of the train and cars = 0.714115 N/(2.35 kg) ≈ 0.304 m/s²

(b) The tension between the locomotive and the car connected to the locomotive = T₂ = ( (m₁ + m₂)/ (m₁ + m₂ + m₃)) × F

Therefore, T₂ =  ( (0.952 + 0.419)/ (0.952 + 0.419 + 0.979)) × 0.714115 ≈ 0.4166 N.

Explanation:

Kepler's family was Lutheran and he adhered to the Augsburg Confession a defining document for Lutheranism. However, he did not adhere to the Lutheran position on the real presence and refused to sign the Formula of Concord. Because of his refusal he was excluded from the sacrament in the Lutheran church. This and his refusal to convert to Catholicism left him alienated by both the Lutherans and the Catholics. Thus he had no refuge during the Thirty-Years War.

The Holy Roman Empire of German Nationality at the Time of Kepler

The Holy Roman Empire of German Nationality at the Time of Kepler.

In 1612 Lutherans were forced out of Prague, so Kepler moved on to Linz. His wife and two sons had recently died. He remarried happily, but had many personal and financial troubles. Two infant daughters died and Kepler had to return to Württemburg where he successfully defended his mother against charges of witchcraft. In 1619 he published Harmonices Mundi, in which he describes his "third law."

In spite of more forced relocations, Kepler published the Epitome Astronomiae in 1621. This was his most influential work and discussed all of heliocentric astronomy in a systematic way. He then went on to produce the Rudolphine Tables that Tycho had envisioned long ago. These included calculations using logarithms, which he developed, and provided perpetual tables for calculating planetary positions for any past or future date. Kepler used the tables to predict a pair of transits by Mercury and Venus of the Sun, although he did not live to witness the events.  

Johannes Kepler died in Regensburg in 1630, while on a journey from his home in Sagan to collect a debt. His grave was demolished within two years because of the Thirty Years War. Frail of body, but robust in mind and spirit, Kepler was scrupulously honest to the data.
