Answer:

El cocodrilo se arrastró durante 20.833 segundos.

Explanation:

El enunciado presenta omisiones y errores conceptuales. La forma correcta es la siguiente: <em>"Un cocodrilo se arrastró 25 metros hacia la derecha con una  rapidez promedio de 1.2 metros por segundo. ¿Cuántos segundos se arrastró el cocodrilo?"</em>

Consideremos que el cocodrilo tiene un movimiento rectilíneo uniforme, el tiempo requerido para el recorrido se calcula con la siguiente ecuación cinemática:

t = \frac{x}{v} (1)

Donde:

x - Distancia recorrida, en metros.

v - Rapidez del cocodrilo, en metros por segundo.

t - Tiempo, en segundos.

Si x = 25\,m y v = 1.2\,\frac{m}{s}, entonces el tiempo empleado por el cocodrilo es:

t = \frac{25\,m}{1.2\,\frac{m}{s} }

t = 20.833\,s

El cocodrilo se arrastró durante 20.833 segundos.

Find the density of a cube on Earth that weighs 1.5 kg and has a side-length of 10 cm.
tamaranim1 [39]

Answer:

1500kg/m^3

Explanation:

Formula:

d=m/v

Given:

m=1.5kg

v=1000cm^3

(The side length of a cube is always equal to the others)

Required:

d=?

Solution:

d=m/v

d=1.5kg/1000cm^3

d=1.5kg/0.001m^3

d=1500kg/m^3

Hope this helps ;) ❤❤❤
