The moment arm of the shoulder abductor muscles is approxi- mately 5 cm from the axis of rotation of the shoulder joint, and the force vector representing shoulder abductor muscle force is oriented at approximately 150° relative to the positive x-axis. the weight of the upper extremity of an 80-kg male is approximately 45 n. if the person is 1.78 m in height, then the center of gravity of the upper-extremity is approximately 0.25 m from the shoulder joint.
3. calculate the vertical component of the joint reaction force.
4. calculate the horizontal component of the joint reaction force.
5. calculate the orientation of the vector representing joint reaction force.

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
