A clock clicks 88 times in 22 seconds. Calculate the frequency and period of the clock.

Consider an object launched vertically upward with an initial speed v. Neglect air resistance.

1. As the projectile goes upward, what energy changes take place?
   • Both kinetic and potential energy decrease.
   • Both kinetic and potential energy increase.
   • Kinetic energy decreases; potential energy increases.
   • Kinetic energy increases; potential energy decreases.
2. At the top point of the flight, what can be said about the projectile's kinetic and potential energy?
   • Both kinetic and potential energy are at their maximum values.
   • Both kinetic and potential energy are at their minimum values.
   • Kinetic energy is at a maximum; potential energy is at a minimum.
   • Kinetic energy is at a minimum; potential energy is at a maximum.

A potential difference of 14V is found to produce a current of0.35 A in a wire of length 3.4 with a uniform radius of 0.33 cm.What is the resistance of the wire? Answer in units of Ω =R=40Ω

What is the resistivity of the wire? Answer in units of Ω*cm

I know I am to use πr^2R/L, but I am coming up wrong somewhere!Please help

Please show step by step the process used.
