Scientific research is sometimes compared to a two-wheeled bicycle. In this comparison, which of the following explains the metaphorical description of the front wheel as beliefs versus what scientists refer to as ideas?

Which basic property determines a colored light's placement on the spectrum of visible light? a. speed b. frequency c. amplitude d. velocity

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)

You can melt ice by applying pressure because the solid/liquid line has a slope.
