Хокеист удря шайбата и тя започва да се хлъзга по леда с ускорение a = 10m/s. Колко метра ще измине шайбата, преди да спре ? Коефициентът на триене между шайбата и леда е k = 0,2

Looking at this barometer, is the air pressure high or low? what type of weather would you expect? high, bad low, bad high, good low, good

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

If two parallel light rays hit a mirror, they will not be parallel to each other after they reflect.
