Answer:
The vibrational frequency of the rope is 5 Hz.
Explanation:
Given;
number of complete oscillation of the rope, n = 20
time taken to make the oscillations, t = 4.00 s
The vibrational frequency of the rope is calculated as follows;
Therefore, the vibrational frequency of the rope is 5 Hz.
Recuerda que distancia=velocidad x tiempo (
). vamos a llamar
a la distancia que reccore el primer bus, y
la distancia que recoore el segundo. Los se econtraran cuando la ditancia recorrida por cada bus sea la misma, es decir
.
Ahora sabemos que la velocidad del primer bus es 30 km/h y su tiempo es
; en cuanto al segundo bus, su velocidad es 45 km/h y como sale 2 horas mas tarde su tiempo será
. Ahora podemos reemplazar los valores en nuestra ecuación de de distanica para hallar el tiempo:
Los buses se encontraran en 6 horas, 4 horas después de haber salido el segundo bus. Ahora para hallar la distancia a la que los buses estaran de <span>san vicente del caguan solo necesitaremos reemplazar la el tiempo en nuestra equación de distancia para el primer bus:
</span>
<span>
En el punto de encuentro los buses estarán a 180 km de San Vicente del Caguan.</span>
Answer:
Banked
Explanation:
Banked curves are formed when the inner edge is below the outer edge.
It is done in order to ensure the reliability of the frictional force as it varies when the road is wet wet or oily. Thus in order to avoid these problems the curved roads are banked.
Banking of the curve provides the necessary centripetal force, i.e., the horizontal component of the normal reaction force to keep the vehicle i motion and thus helps in reducing the effect of the forward motion force on the vehicle.
If Adam is pulling with a pulling force of 120N, and the nets pulling force is 200N, and they are both going north, then that means that Krystal would have a a pulling force of 80N north, as 200N- 120N is 80N. She would be pulling north because she is on the same side as Adam, helping to pull the sled upwards.
