If two wires run parallel and the current passes through
both wires in the same direction, which happens to the wires?
If two wires run parallel and the current passes through
both wires in the same direction, the wires wires move together because the
current of one wire pulls the other wire closer. The answer is letter C.
Answer:
Angle turn pulley is 113 rad
Explanation:
given data
angular speed w = 12.5 rad/s
angular acceleration a 3.41 rad/s²
time t = 5.26 s
to find out
what angle does the pulley turn
solution
we get here angle by this equation that is here
angle turn = w × t + 0.5 × a × t² ......................1
put here value we get
angle turn = w × t + 0.5 × a × t²
angle turn = 12.5 × 5.26 + 0.5 × 3.41 × 5.26²
Angle turn = 65.75 + 47.17
Angle turn = 112.92 rad = 113 rad
<span>The question is 'a centre seeking force related to acceleration is ............... force. The answer is centripetal force. Motion in a curved path is an accelerated motion and it requires a force that will direct the moving object towards the centre of curvature of the path of motion. This centre seeking force is known as centripetal force.</span>
