You are designing a rotating metal flywheel that will be used to store energy. the flywheel is to be a uniform disk with radius 27.0 cm . starting from rest at t = 0, the flywheel rotates with constant angular acceleration 3.00 rad/s2 about an axis perpendicular to the flywheel at its center if the flywheel has a density (mass per unit volume) of 8600 kg/m3, what thickness must it have to store 800 j of kinetic energy at t = 8.00 s?

Apatient has a history of poor nutrition. he has skin rashes, bleeding gums, and a cut that hasn’t healed in a long time. what vitamin deficiency most likely caused this symptom?

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

Scientific models are based on current knowledge, which can limit their effectiveness when new discoveries are made.
