It is often more convenient to express distance in m rather than m and frequency in Hz rather than Hz. Rewrite the equation for free space loss, = 20log + 20log − 147.56 , using the new dimension units.

Explain why electric current cannot exist if a current doesn't have a voltage source.

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
