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:
(1)
Donde:
- Distancia recorrida, en metros.
- Rapidez del cocodrilo, en metros por segundo.
- Tiempo, en segundos.
Si
y
, entonces el tiempo empleado por el cocodrilo es:
![t = \frac{25\,m}{1.2\,\frac{m}{s} }](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7B25%5C%2Cm%7D%7B1.2%5C%2C%5Cfrac%7Bm%7D%7Bs%7D%20%7D)
![t = 20.833\,s](https://tex.z-dn.net/?f=t%20%3D%2020.833%5C%2Cs)
El cocodrilo se arrastró durante 20.833 segundos.

Answer:
500,050000 years
Explanation:
Given that :
Rate of Accumulation = 3cm/ 1000 years
Height of seamounts = 1.5km
Representing height of seamounts in cm;
(1.5 *1000 * 100) = 1500150 cm
Time taken = height / rate
Time taken = (1500150 cm / 3cm) * 1000
Time taken = 500,050000 years
Answer:
Yes. Weight is the product of mass times gravitational acceleration. So all you have to do is vary the gravitational field and you vary weight.
Explanation:
Answer:
Melting of snow
Evaporation of water from desk
Explanation:
Processes that increase the entropy of the universe are those processes that have an increased disorderliness. We should note that there are three principal states of matter which are the liquid, gas and solid. The gaseous state is the most disorderly while the solid is the least disorderly.
Now. We can see that the cooling of a hot cup of coffee is a process that needs or leads to a loss in temperature which obviously decreases disorderliness of the universe.
The melting of snow however is a process that leads to an increase in the disorderliness of the universe. It entails moving from the solid state to the liquid state. It tends to move to a more disordered state indicating an increase in the entropy of the universe.
The evaporation of water from the desk is quite similar to that above. Hence since we are moving from the liquid to the gaseous state via evaporation, we can state that the entropy of the universe has increased since we have moved from a state with a lesser degree of disorderliness to a state that is more disordered I.e from liquid to gaseous state.
