. An ice skater with a mass of 70 kg pushes off against a sec- ond skater with a mass of 30 kg. Both skaters are initially at rest. a. What is the total momentum of the system after they push off? b. If the larger skater moves off with a speed of 2.8 m/s, what is the corresponding speed of the smaller skater?

Ohm's law
Ohm’s law is a prominent concept in physics and electronics. It gives the relation between the current and the voltage. It is used to analyze and construct electrical circuits. Ohm's law states that the voltage across a conductor is directly proportional to the current flowing through it.
Path of Least Resistance
In a series of alternate pathways, the direction of least resistance is the actual or metaphorical route that offers the least resistance to forwarding motion by a given individual or body.
