Um corpo de 5 kg desliza ao longo de um plano inclinado em um ângulo de 45° com relação à superfície horizontal, sob a influência da gravidade. Sabendo que o corpo desliza com velocidade constante, o módulo da força resultante sobre esse corpo é igual a: URGENT! ALGUEM???​

Apossible explanation for a set of facts that can be tested by further investigation is called

The 10-kg double wheel with radius of gyration of 125mm about o is connected to the spring of stiffness k = 600 n/m by a cord which is wrapped securely around the inner hub. if the wheel is released from rest on the incline with the spring stretched 225 mm, calculate the maximum velocity v of its center o during the ensuing motion. the wheel rolls without slipping

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat
