A well preserved piece of wood found at an archaeological site has 4.9 % of the carbon-14 that it must have had when it was living. Using the fact that carbon-14 has a half-life of 5700 years, calculate the age (in years) of this piece of

What is the measure of a change in an objects velocity?

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

What is the speed vfinal of the electron when it is 10.0 cm from charge 1?
