A mass of 3.1 kg, which may be considered to be a point mass, is attached to a string of length 0.75 m and is rotated at a linear speed of 2.4 m/s. Calculate the moment of inertia of the mass about the axis and calculate its angular momentum. (ignore the mass of the string)

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

How much energy is supplied to each coulomb of charge that flows through a 12-v battery?

The first law of thermodynamics states that heat added to a system is neither created nor destroyed but is as it changes into other forms of energy.
