Un deposito con la forma y las dimensiones 1,5m, 2m, y 0,5m esta lleno de aceite que tiene una densidad de 0,92g/cm^3 cual es la presión en el fondo del recipiente ?de terminar la fuerza que hay en el fondo del recipiente

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

Anybody wanna ? (picture included? )

How is the acceleration of an object in uniform circular motion constant? a - in magnitude only b - in direction only c - in both magnitude and direction d - in magnitude, direction & orientation
