Explanation:
Historical sources believe that Henry Ford first saw parts made from vanadium steel in Europe which were been used on racing cars and luxurious vehicles.
Ford was impressed due to the fact that Vanadium steel unlike normal steel was cheaper and at the same time stronger and lighter if it was used on automobiles.

Un automóvil viajó 186.4 Km a una velocidad constante de 57 Km/h. ¿Cuánto tiempo se necesitó para el viaje?
Answer:
t = 1.177 10⁴ s
Explanation:
For this exercise we use the uniform motion relationships
v = x / t
t = x / v
let's reduce the magnitudes to the SI system
v = 57 km / h (1000m / 1km) (1h / 3600s) = 15.833 m / s
x = 186.4 km (1000m / 1 km) = 186.4 10³ m
let's calculate
t = 186.4 10³ / 15.833
t = 11.77 10³ s
t = 1.177 10⁴ s
pls help i’ll give brainliest if you give a correct answer!!
Answer:
the applied force is greater than the force of friction
Explanation:
pls give brainliest it makes me feel smart
Answer:
hi!
Explanation:
The answer is option b.
A box can definitely not move on it's own unless an external force is applied i.e muscular force. If the applied force would have been less than the force of friction then the box would have never displaced. But, since the box is able to move, we can imply that, the applied force is greater than the frictonal force leading in the displacement of the box.

Discuss how the motion of the stunt cyclist relates to the forces acting on the stunt cyclist during the collision
Answer:
hello your question is incomplete hence I will give you a general answer on how a stunt cyclist performs his stunts successfully
answer ;
The stunt cyclist trying to perform some sort of stunt with the bicycle will be faced with some forces like the static fiction between the tires of the bicycle and wall and also a centripetal force.
In order to overcome the centripetal force the minimal grip of the bicycle must be equal to the weight and the speed at which the cyclist must go can be represented as :
[tex]V_{min} = \sqrt{\frac{r.g}{u} }[/tex]

Why can’t the high-quality energy released from a lump of burning coal be recycled?
Answer:
when energy changes from one form to another, it always goes from a more useful to a less useful form. This means that people can't recycle or reuse high quality energy to perform useful work.
When energy changes from one form to another, it always transitions from a more helpful to a less useful one. Because of this, people are unable to reuse or recycle high-quality energy to complete crucial tasks.
What is the term of burning coal?Coal is most frequently and significantly used in combustion, where heat is produced to create steam, which in turn powers the turbines that generate electricity. All living things, including humans, are composed of carbon. However, as coal burns, its oxygen reacts with airborne oxygen to generate carbon dioxide. Although dioxide (CO2) is an odourless, colourless gas, it is one of numerous gases found in the atmosphere that can retain the heat from the planet.
Why is burning coal a problem?It's a major issue for climate change since it produces more carbon dioxide when burned than oil or gas. In addition to producing microscopic soot particles and hazardous substances like arsenic and mercury, coal also contributes to air pollution.

What does the investigation of Earth's layers reveal about the history of the
formation of our planet?
Answer:
there's a center of the earth..and there is every later of it..just like in a movie...it is true
Answer:
The layers of rock at Earth ’s surface contain evidence of the evolutionary processes undergone by these components of the terrestrial environment during the times at which each layer was formed. By studying this rock record from the very beginning, it is thus possible to trace their development and the resultant changes through time.
El Burj Khalifa es la torre más alta de Dubai y mide 821 m. Si se deja caer una moneda desde lo alto de la torre, ¿cuál es la magnitud de la velocidad con la que choca con el suelo?
Answer:
Vf = 126,85 m/s
Explanation:
En este caso, vamos a asumir que la velocidad inicial de la moneda cuando se deja caer es cero, puesto que no nos lo indican. Al ser la velocidad inicial cero, lo unico que influye en la velocidad de la moneda es la gravedad y la altura, por ende, la siguiente formula nos ayudará a calcularla:
Vf² = Vo² - 2gh (1)
Pero como la velocidad inicial es cero, y si también asumimos que la dirección de bajada será nuestro eje positivo, entonces:
Vf² = 2gh (2)
Ahora solo nos queda, reemplazar los valores de altura que es 821 m, y la aceleración de gravedad que es 9.8 m/s² y resolvemos la velocidad:
Vf² = 2 * 9,8 * 821
Vf = √16091,6
Vf = 126,85 m/sEsta debería ser la velocidad con que llega al suelo.
Exitos
La magnitud de la velocidad con la que choca con el suelo es aproximadamente 126.898 metros por segundo.
Si despreciamos los efectos de la viscosidad del aire y la aceleración de Coriolis, entonces el movimiento de la moneda se describe por el movimiento de caída libre, es decir, un movimiento uniforme acelerado debido a la gravedad terrestre. La velocidad final de la moneda es determinada por la siguiente ecuación cinemática:
[tex]v = \sqrt{v_{o}^{2}+2\cdot a\cdot h}[/tex] (1)
Donde:
[tex]v_{o}[/tex] - Velocidad inicial, en metros por segundo.[tex]a[/tex] - Aceleración, en metros por segundo al cuadrado.[tex]h[/tex] - Altura, en metros.[tex]v[/tex] - Velocidad final, en metros por segundo.Si sabemos que [tex]v_{o} = 0\,\frac{m}{s}[/tex], [tex]a = 9.807\,\frac{m}{s^{2}}[/tex] y [tex]h = 821\,m[/tex], entonces la velocidad final de la moneda es:
[tex]v = \sqrt{\left(0\,\frac{m}{s} \right)^{2}+2\cdot \left(9.807\,\frac{m}{s^{2}} \right)\cdot (821\,m)}[/tex]
[tex]v\approx 126.898\,\frac{m}{s}[/tex]
La magnitud de la velocidad con la que choca con el suelo es aproximadamente 126.898 metros por segundo.

2, A rectangular Container of base 50 cm by 30cm is filled with water to be depth of 5cm. how much is the pressure exerted at the base? (take pw= 1000kg /m3 and g=10m/s)
Answer:
P = 500 N/m²
Explanation:
Pressure exerted at the base is the hydrostatic pressure and it is given by the formula;
P = ρgh
Where;
ρ is density = 1000 kg/m³
g = 10 m/s²
h is depth = 5 cm = 0.05 m
Thus;
P = 1000 × 10 × 0.05
P = 500 N/m²
If a storm is 7.5 kilometers away, how much time is expected between observations of lightning and thunder?
Answer:
≈ 22 seconds
Explanation:
7,5 km = 7500 m
Speed of light 300 000 000 m/s (for lightning)
Speed of sound 343 m/s (for thunder)
time = distance / speed
lightning time = 7500 m / 300 000 000 m/s = 0.000025 s
thunder time = 7500 m / 343 m/s ≈ 22 s
thunder time - lightning time = 22 s - 0.000025 s ≈ 22 s

What is Newton's Second Law?
1.The attraction between objects
2.An object at rest tends to stay at rest and an object in motion tends to stay in motion unless acted upon by an unbalanced force
3.An object's acceleration depends on its mass and on the net force acting on it.
4.For every action there is an equal and opposite reaction
Answer:
An object's acceleration depends on its mass and on the net force acting on it.
Explanation:
Newton's second law states that the acceleration of an object is directly related to the net force and inversely related to its mass. Acceleration of an object depends on two things, force and mass.
Answer:
3.An object's acceleration depends on its mass and on the net force acting on it.

Answer:

if the charge of the force is doubled would the force double
Answer: The electrostatic force between two point charge particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. So, if you double the individual charges while keeping the same distance, the net electrostatic force will be four times the previous value.
Explanation:
Since, we know
F = (k×q1×q2)/r²
When the charges are doubled, we have :
F' = (k × 2q1 × 2q2)/r²
F' = 4 (k×q1×q2)/r²
Thus,
F' = 4F
Hence, the force becomes 4 times its initial value.
