I think the land between two faults that may be uplifted are formed into mountians
Answer:
See explanation
Explanation:
In this exercise, we need to use the law of conservation of angular momentum which is:
I1*W1 + I2*W2 = (I1 + I2)*W2'
Where:
I: moment of innertia.
W: angular velocity
Now let's call 1 the runner and 2, the turntable. the system would be W2'.
The angular speed of the runner, we can calculate that with the following expression:
W = V/r
so:
W1 = 2.5 / 3.6 = 0.694 rad/s
The innertia is calculated with the expression:
I = m*r²
I = 60 * 3.6 = 216 kg.m²
I2 and W2 are provided in the exercise, so, replacing all the data in the conservation of angular momentum, let's solve for W2'
(216*0.694) + (-0.190*81) = (81 + 216)W2'
134.514 = 297W2'
W2' = 134.514 / 297
W2' = 0.453 rad/s
Total distance: 56 meters. Magnitude and direction of displacement: 20 meters South.
Explanation:
The term distance refers to space between one point and other, or the total space a body or object covered while moving. In the case presented, this can be calculated by adding the partial distances given. This means the total distance is 56 meters as 26 meters + 18 meters + 12 meters = 56 meters.
On the other hand, displacement considers the distance from the initial position to the final position, and the direction of movement. This means partial distances should not be added but each movement should be considered according to the direction. The process is shown below:
-The first movement was 26 meters southward; this means by the end of this movement the distance between the initial position was 26 meters south.
- The second movement was 18 northward; this means the kayaker moved 18 meters towards the position. This changes the displacement to 8 meters South as 26 meters south - 18 meters north = 8 meters to the South.
-The last movement was 12 meters sound; this means the kayaker increased the distance from the original position 8 meters to the South + 12 meters to the South = 20 meters South (total displacement.)
A True it shows that you are very grateful for the opportunity and it shows that you really would like the job and you’re not just doing it for the money even if you are. Also it just shows professionalism
When a force acts upon an object it will cause that object to move forward or however the force acted upon it. An object will stay in motion til a force acts on it
