G An applied voltage V(t) produces current i(t), which causes a nonlinear magnetic force to act on the steel ball. The objective is to levitate the ball by manipulating the voltage. As the ball moves, it alters the circuit inductance in a nonlinear fashion. The state equations for this system are given by:

Need asap ‼️ 20 pts which gravitational force field diagram is drawn correctly? (answers in pictures below)

Infrared radiation has wavelengths that are shorter than visible light is part of the visible light spectrum has wavelengths that are longer than visible light has the same wavelengths as ultraviolet radiation

Arefrigerator uses r-134a as the working fluid and operates on the ideal vapor-compression refrigeration cycle except for the compression process. the refrigerant enters the evaporator at 120 kpa with a quality of 34 percent and leaves the compressor at 70°c. if the compressor consumes 450 w of power, determine (a) the mass flow rate of the refrigerant, (b) the condenser pressure, and (c) the cop of the refrigerator. (0.00644 kg/s, 800 kpa, 2.03)
