QUICK, SHOW WORK PLS The radius of the Earth may be taken to be
6,371 km. Assume a satellite is in orbit at an
altitude he above the Earth, so R =
6,371+he km. If the period of the orbit of the
satellite around the Earth is 90.0 min, what is
the altitude, he, of the satellite (km)?
he = [ ? ] km

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
