Answer:
9.52 am
Explanation:
The p-waves travel with uniform motion (constant velocity), so we can calculate the time they take to travel from the epicenter to the point where they are recorded using
where
d is the distance covered
v is the speed of the p-waves
On average, the speed of p-waves is
v = 7 km/s
Here they have to cover a distance of
d = 5600 km
So, the time they take is:
Converting into minutes,
Since they were recorded at 10.05 am, it means the earthquake occurred 13 minutes before that: so, at 9.52 am.
A) The car moves in the direction opposite of the action force.
By Newton's 3rd Law, for every action, there is an equal and opposite reaction.
Answer:
According to your question although you didn't include the options, it is obvious that when air pressure is acting on an object ,there is just as much air pressure pushing up as there is pushing down on the object,thereby creating a balanced for the object.
Because my dad had the dominant gene for brown hair, while my mom had the recessive gene, I now have brown hair.
Hope this helped! Good luck! :)
Answer: El trabajo realizado al desplazar el bloque es: 75 N.m
Datos:
Fuerza= F= 25 N
Distancia= d= 3 m
Explicación:
El trabajo es el producto de la fuerza ejercida sobre un cuerpo con el desplazamiento producido por la fuerza. Para que exista trabajo, la dirección de la fuerza debe ser igual a la dirección del desplazamiento.
Trabajo= Fuerza x Desplazamiento
Reemplazando los datos:
T= 25 N * 3 m
T= 75 N.m
