Answer:

Commutative

Explanation:

In a binary operation the commutative property states that the order of the operations does not matter For, example a + b is equal to b + a. So, it does not matter if we add b to a first or a to b first i.e., the order does not matter. The statement shown here is

If t - 13 = 52, then 52 = t - 13 is displaying the commutative property.

The property illustrated to each statement is commutative because it shows that for some value of t both statements are equal.

Un avión vuela a 10000m de altura y otro a 33300 pies, si un pie equivale a 30.48cm ¿Cuál vuela a mayor altura?
user100 [1]

Answer:

Avion A (10000 meters).

Explanation:

Deje que la altura de los aviones sea A y B respectivamente.

Dados los siguientes datos;

Altura A = 10000 metros

Altura B = 33300 pies

Para encontrar el avión que voló más alto, tendríamos que hacer alguna conversión de unidades.

Conversión:

Metros a centímetros;

1 metro = 100 cm

10000 metros = 100 * 10000 = 1.000.000 centímetros.

Por lo tanto, la altura A en cm = 1,000,000 centímetros

Pies a centímetros;

1 pie = 30,48 centímetros

33300 pies = 33300 * 30,48 = 1014984 centímetros.

Por lo tanto, la altura B en cm = 1014984 centímetros.

De los cálculos anteriores, podemos deducir que el avión A voló más alto.

Si un auto se mueve en rapidez constante de 25,0m/s a lo largo de 2500 m en línea recta, ¿cuál es la magnitud de la fuerza resul
Nataly_w [17]

Answer:

F= 0

Explanation:

This exercise we use Newton's second law,

            F = m a

in this case as the speed is constant the acceleration is zero therefore the force is zero.

Change we can solve it using Newton's first law, which states that every vehicle remains still or with constant speed if there is no extensive outside acting on it

We see that with any of the two forms the sum of the applied forces is zero

                     ∑ F = 0

What is the electric field at the position (x2,y2)=(−5.0cm , 0cm) in component form?
insens350 [35]

Complete Question: A +10 nC charge is located at the origin. What is the electric field at the position (x2,y2)= (-5.0cm, 0cm)? Write electric field vector in component form.

E2x, E2y=? N/C

Answer:

Ex = -3.6*10⁴ N/C   Ey=0

Explanation:

As the charge producing the field is positive, the direction of the field, which is the one that would take a positive test charge located in the point of interest, will be away from this point, pointing to the left.

If we choose the positive direction to be to the right, the electric field component along the x-axis will be negative.

The magnitude of the field can be obtained applying the electric field definition, and the Coulomb's Law to the charge in the origin, as follows:

E = k*q/r² = 9*10⁹N*m²/C²*10⁻⁸C/(0.05)² m² = 3.6*10⁴ N/C

As the electric field follows the same line as the electric force, it has only component on the x axis, so:

Ex = -3.6*10⁴ N/C  

Ey = 0

Ariel and Jackson are playing miniature golf. Ariel's ball rolls into a long, straight upward incline with a speed of 3.054 m/s
Salsk061 [2.6K]

Answer:

The length is s =  3.73 \ m

Explanation:

From the question we are told that

  The speed is  v  =  3.054 \  m/s

  The acceleration a =  -0.7762  m/s^2

   The time taken is  t =  1.51 \ s

     

Generally from kinematics equation the length of the inclined plane is mathematically represented as

         s =ut + \frac{1}{2} * at^2

=>      s = 3.054 *1.51  + \frac{1}{2} * (-0.7762) *(1.51)^2

=>   s =  3.73 \ m
