Answer:
convergent
Explanation:
Convergent limits are the type of boundary defined by the movement of the plates in the direction of approach, that is, when two tectonic plates move in a convergent direction, colliding between them frontally. In these cases, the dense plate dips under the lightest one, being incorporated into the warm material and fluid of the mantle.
A tsunami can be generated when the boundaries of converging tectonic plates move. For this reason, we can conclude that the type of board boundary that is close to the area that Marina has been studying is a convergent limite.
Answer:
the final speed of the stool is 3.6 rad/s
Explanation:
As we know that there is no external torque on the system
So we can use concept of angular momentum conservation
So we will have
now we will have
So the final speed of the stool is 3.6 rad/s
Let D be the total distance (say in meters) traveled by the train and T the time (say in seconds) it takes to do so. (Assume the train moves in a straight line in only one direction.) Then the average velocity of the train as it covers this distance is
v (ave) = D/T
We're told the train can traverse a distance of D/4 in a matter of T/2 seconds if it moves at a speed of 5 m/s. This means
D/4 = (5 m/s) (T/2)
⇒ 5 m/s = 1/2 D/T
⇒ v (ave) = D/T = 10 m/s
Answer:
Explanation:
v = Final velocity
u = Initial velocity
a = Acceleration
t = Time
s = Displacement
Here the kinematic equations of motion are used
Time the car is at constant velocity is 39 s
Time the car is decelerating is 5 s
Total time the car is in motion is 
Distance traveled
The total displacement of the car is 
Average velocity is given by
The average velocity of the car is .
