Answer:
-36.4 m/s
Explanation:
final velocity= initial velocity + acceleration x time
7 + (-9.8)(3)= -36.4 m/s
Magma forms by partial melting of upper mantle and crust. Partial melt means that only a fraction of the available material forms a melt, and that the remainder stays solid. The partial melt rises because of its lower density and ascends through he crust.
There are several information's of immense importance already given in the question. Based on the given information's the answer to the question can easily be determined.
Distance covered by the bicycle = 5000 meter
Time taken by the bicycle to reach the distance = 500 second.
Velocity of the bicycle = Distance / Time taken
= 5000/500 meter/second
= 50 meter/second
So the velocity of the bicycle is 50 meter per second. I hope the procedure is clear enough for you to understand. In future you can always use this procedure for solving similar problems.
Answer:
The tension is
The horizontal force provided by hinge
Explanation:
From the question we are told that
The mass of the beam is
The length of the beam is
The hanging mass is
The length of the hannging mass is
The angle the cable makes with the wall is
The free body diagram of this setup is shown on the first uploaded image
The force are the forces experienced by the beam due to the hinges
Looking at the diagram we ca see that the moment of the force about the fixed end of the beam along both the x-axis and the y- axis is zero
So
Now about the x-axis the moment is
=>
Substituting values
Now about the y-axis the moment is
Now the torque on the system is zero because their is no rotation
So the torque above point 0 is
The horizontal force provided by the hinge is
Now substituting for T
