Awater wave travels across a 90-meter wide pond in 15.0 seconds. the speed of the wave is 1,350 m/s 6 m/s 0.167 m/s impossible to determine without knowing the temperature of the water

The image shows a pendulum in simple harmonic motion the pendulum starts at a and swing to e

Compare the horizontal displacement of the two balls as they travel to the ground. what do you observe?

Acommercial refrigerator with refrigerant-134a as the working fluid is used to keep the refrigerated space at -35°c by rejecting waste heat to cooling water that enters the condenser at 18°c at a rate of 0.25 kg/s and leaves at 26°c. the refrigerant enters the condenser at 1.2 mpa and 50°c. if the compressor consumes 3.3 kw of power, determine (a) the mass flow rate of the refrigerant, (b) the refrigeration load, (c) the cop, and (d) the minimum power input to the compressor for the same refrigeration load.
