Un automóvil se mueve 80 m en 40 s con una velocidad constante. ¿Cuál es la velocidad del automóvil? Ayuda plissssssssssssssssss
Alexxandr [17]

Answer:

Velocidad = 2 m/s

Explanation:

Dados los siguientes datos;

Distancia = 80 m

Tiempo = 40 s

Para encontrar la velocidad del automóvil;

La velocidad se puede definir como la tasa de cambio en el desplazamiento (distancia) con el tiempo.

La velocidad es una cantidad vectorial y, como tal, tiene magnitud y dirección.

Matemáticamente, la velocidad viene dada por la ecuación;

Velocidad = \frac {distancia} {tiempo}

Sustituyendo en la fórmula, tenemos;

Velocidad = 80/40

Velocidad = 2 m/s

The Bohr model below represents which answer Choice
Anton [14]

Answer:

Na⁺

Explanation:

In the given atom:

  Number of protons  = 11

  Number of neutrons  = 12

So, the number of electrons  = 10

The number of protons within an atom is used to determine the kind of atom we have been given.

Since the number of protons is the same as the atomic number, here the atomic number is 11 and this is Sodium .

 In this sodium atom, the number of protons is more than the number of electrons;

 Charge = number of protons  - number of electrons  = 11 - 10  = +1

So, we have a Na⁺

The energy of motion is called
liubo4ka [24]
<span>A. kinetic energy. </span>

Friction converts kinetic energy into heat, and so it represents a net loss of mechanical energy. When surfaces in contact move relative to each other, the friction between the two surfaces converts kinetic energy into heat. As demonstrated by the use of friction created by rubbing pieces of wood together to start a fire, kinetic energy is converted to heat whenever motion with friction occurs. The friction produced by brake pads in a car must generate a quantity of heat equal to the kinetic energy of the car and as a result, the brakes get quite hot.
