A particle has centripetal acceleration whenever it's a making a turn of radius R. If the particle is moving at a constant tangential speed v throughout the turn, then the magnitude of centripetal acceleration is
v²/R
If the particle is following a uniformly circular path, then it moves in a circle of radius R and travels a distance equal to its circumference, 2πR. Let T be the time it takes to complete one such loop. Then the entire circle is traversed with speed v = 2πR/T, so that the centripetal acceleration is also given by
v²/R = (2πR/T)²/R = 4π²R/T²
Then the magnitude of the net force is the difference between the two forces,
and its direction is the same as the direction of the greater one.
Hey, Terrizzif!
STIs are caused by sexual transmission, they are spread by sexual intercourse.
I hope this helps;)
The Resistance is directly proportional to conductor length. Therefore 30% increase in wire length will increase the resistance by 30%.
