When a certain force is applied to the 1-kg standard mass its acceleration is 5.0 meter per second square. When the same force is applied to another object its acceleration is one-fifth as much. The mass of the object is:

Ammonia enters the expansion valve of a refrigeration system at a pressure of 10 bar and a temperature of 18oc and exits at 6.0 bar. the refrigerant undergoes a throttling process. determine the temperature, in oc, and the quality of the refrigerant at the exit of the expansion valve.

Juan created a chart to him study for a test. which headings best complete the chart? x: transparent objects y: opaque objects x: opaque objects y: transparent objects x: high frequency waves y: low frequency waves x: low frequency waves y: high frequency waves

The force it would take to accelerate an 900-kg car at the rate of 6m/s2
