A force acts on a particle as the particle moves along an x axis, with in newtons, x in meters, and c a constant. At x = 0 m, the particle's kinetic energy is 19.0 J; at x = 4.00 m, it is 11.0 J. Find c.

Crowbar of 5 metre is used to lift an object of 800 metre if the effort arm is 200cm calculate the force applied

Which situation will have the highest resistance? a.long wire and high temperatureb.short wire and high temperaturec.long wire and cold temperaturedshort wire and low temperature
