Answer:

convection is more important

In convection there is actual movement of fluid particles for heat transfer whereas in conduction, the particles only vibrate at their position and transfer heat. Due to this kinetic energy transfer in convection is faster than conduction and hence convection is the more efficient way of heat transfer than conduction

<h3><u><em>Answer:</em></u></h3><h3><u><em>Ok, here we go...</em></u></h3><h3><u><em>Explanation:</em></u></h3><h3><u><em>Astronauts perform many tasks as they orbit Earth. The space station is designed to be a permanent orbiting research facility. Its major purpose is to perform world-class science and research that only a microgravity environment can provide. The station crew spends their day working on science experiments that require their input, as well as monitoring those that are controlled from the ground. They also take part in medical experiments to determine how well their bodies are adjusting to living in microgravity for long periods of time.</em></u></h3><h3><u><em></em></u></h3><h3><u><em>Working on the space station also means ensuring the maintenance and health of the orbiting platform. Crew members are constantly checking support systems and cleaning filters, updating computer equipment: doing many of the things homeowners must do to ensure their largest investment stays in good shape. Similarly, the Mission Control Center constantly monitors the space station and sends messages each day through voice or email with new instructions or plans to assist the crew members in their daily routines.</em></u></h3><h3><u><em></em></u></h3>

Refrigerant entering the compressor of a refrigeration system is a:________

schepotkina [342]

Refrigerant entering the compressor of a refrigeration system is sub-cooled liquid

The liquid refrigerant is sub-cooled to ensure that only liquid and not the vapour enters the throttling valve. In a refrigeration system, the superheating decreases COP increase refrigerating effect but increasing amount of work done. The coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work (energy) required. Higher COPs equate to higher efficiency, lower energy (power) consumption and thus lower operating costs.

The speed of sound is 346m/s if a sound wave travels at a frequency of 55hz what would it’s wavelength be

algol [13]

Answer:

6.29 m

Explanation:

The speed of a wave is equal to frequency times wavelength, so to find wavelength you'd have to divide frequency by both sides, speed(346) divided frequency(55) = 6.29 m

I'm not so sure about this let me know if I'm wrong
