Un automóvil viaja a la velocidad de 10 m/s. Se acelera Durante 12s y aumenta su velocidad hasta 70 m/s ¿Que aceleración experimenta el automóvil?
Answer:
Aceleracion = 5 m/s²
Explanation:
Dados los siguientes datos;
Velocidad inicial = 10 m/s
Velocidad final = 70 m/s
Tiempo, t = 12 segundos
Para encontrar la aceleración;
Aceleración se puede definir como la tasa de cambio de la velocidad de un objeto con respecto al tiempo.
Esto simplemente significa que la aceleración viene dada por la resta de la velocidad inicial de la velocidad final a lo largo del tiempo.
Por lo tanto, si restamos la velocidad inicial de la velocidad final y la dividimos por el tiempo, podemos calcular la aceleración de un objeto. Matemáticamente, la aceleración viene dada por la fórmula;
[tex] Aceleracion = \frac{final \; velocidad - inicial \; velocidad}{tiempo}[/tex]
Sustituyendo en la fórmula, tenemos;
[tex] Aceleracion = \frac{70 - 10}{12}[/tex]
[tex] Aceleracion = \frac{60}{12}[/tex]
Aceleracion = 5 m/s²

What happens to the force between two charges when each charge is doubled and the distance between them is 1/4 its original
magnitude?
Answer:
F' = 64 F
Explanation:
The electric force between charges is given by :
[tex]F=\dfrac{kq_1q_2}{r^2}[/tex]
Where
q₁ and q₂ are charges
r is the distance between charges
When each charge is doubled and the distance between them is 1/4 its original magnitude such that,
q₁' = 2q₁, q₂' = 2q₂ and r' = (r/4)
New force,
[tex]F'=\dfrac{kq_1'q_2'}{r'^2}[/tex]
Apply new values,
[tex]F'=\dfrac{k\times 2q_1\times 2q_2}{(\dfrac{r}{4})^2}\\\\=\dfrac{k\times 4q_1q_2}{\dfrac{r^2}{16}}\\\\=64\times \dfrac{kq_1q_2}{r^2}\\\\=64F[/tex]
So, the new force becomes 64 times the initial force.

how can you show that an electric current has a magnet affect
Answer:
It is observed that when a compass is brought near a current carrying conductor the needle of compass gets deflected because of flow of electricity. This shows that electric current produces a magnetic effect.
Observe: Click Reset. Turn on Show velocity vector and Show velocity components. Set vinitial to 50 m/s and set θ to 45.0 degrees. Click Play. Focus on the blue and red arrows that represent the vertical and horizontal components of the golf ball’s velocity. As the ball flies through the air, what do you notice about the blue (vertical) arrow?
Answer:
v_y = v_{oy} - g t
where the upward direction is positive, so the arrow represents this speed (blue) must decrease, reach zero and grow in a negative direction as time progresses
Explanation:
In this exercise you are asked to observe the change in velocity in a projectile launch.
If we assume that the friction force is small, the velocity in the x-axis must be constant
vₓ = v₀ₓ
Therefore, the arrow (red) that represents this movement must not change in magnitude.
In the direction of the y axis, the acceleration of gravity is acting, so the magnitude of the velocity in this axis changes
v_y = v_{oy} - g t
where the upward direction is positive, so the arrow represents this speed (blue) must decrease, reach zero and grow in a negative direction as time progresses
Which of these actions does NOT have a vector?
O Swinging from a wire

What three factors affect the acceleration of an object?
Explanation:
The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased
The three factors are net force, the mass of the object and the direction of the force.
What is acceleration?Acceleration is defined as the rate of change of velocity. It is also defined as the ratio of the net force acting on the body to the mass of the body.
The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. and the direction of the force.
As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.
Therefore three factors are net force, the mass of the object and the direction of the force.

A car drives 30 m north in 1.5 seconds and drives 60 east in 2 seconds. What is the average velocity
Answer:
19.2 m/s
Explanation:
From the question,
Velocity = displacement/time = d/t
V = d/t.................................. Equation 1
Average velocity = Total displacement/ total time
Total dispalcement = √(30²+60²) = √4500 = 67.08 m
Total time = 1.5+2 = 3.5 s.
Substitute these value into equation 1
V = 67.08/3.5
V = 19.2 m/s.
Hence the average velocity is 19.2 m/s
The parameter given for the car during transit is 30 m north in 1.5 seconds and drives 60 east in 2 seconds, we want to find the average velocity.
average velocity is 19.2 m/s
Solution
The expression for Average velocity is
Average velocity = Total Displacement/ Total time Taken...............Eqn 1
Total Displacement = √(30²+60²) = √4500 = 67.08 m
Total time = 1.5+2 = 3.5 s.
From the Equation 1
Average Velocity = 67.08/3.5
V = 19.2 m/s.
Therefore, the average velocity is 19.2 m/s

[tex]3.71\ \text{m/s}[/tex]
[tex]1.23\ \text{km/s}^2[/tex]
[tex]20.28\ \text{m}[/tex]
Explanation:
r = Radius of disk = 7.9 cm
N = Number of revolution per minute = 1190 rev/minute
Angular speed is given by
[tex]\omega=N\dfrac{2\pi}{60}\\\Rightarrow \omega=1190\times \dfrac{2\pi}{60}\\\Rightarrow \omega=124.62\ \text{rad/s}[/tex]
