Answer:
yes
- electric and/or hybrid cars
- microwave ovens
- LED lighting
- low-power electronics
Explanation:
Advances in technology and changes in social organization have brought about reductions in energy use on many fronts.
- hybrid/electric vehicles have reduced transportation energy needs
- microwave ovens have reduced cooking energy needs
- LED lighting has reduced lighting energy needs
- low-power electronics have reduced the energy cost of technology and entertainment
- heat pumps and insulated windows have reduced energy needs for home heating and cooling
- zoning laws have reduced the need for travel to work and shopping areas
Answer:
Sensor/transducer: bimetallic thermometer
Output: displacement of thermometer tip
Control Tstages: mercury contact switch (open:furnace off; closed:furnace on
Explanation:
for a standard room thermostat
: This is the device that sets/determines the temperature of an enclosure.
Sensor/transducer: bimetallic thermometer: Bimetalic thermometer are used for measuring the temperature of the ambient air
. bimetallic thermometer actually contains two metals. they undergo linear expansivity as the temperature of the room changes.in other words, they experience contraction and expansion with increase or decrease in temperature.The sensor is basically coupled with a transducer which turns the measured variable(Temperature) into something else, such as a movement on a dial or an electrical signal
Output: displacement of thermometer tip
Controller: mercury contact switch (open:furnace off; closed:furnace on)
once the contact switch is open the furnace can go off. when the contact switch is closed, the furnace will come up.
Generally, frictional losses are more predominant for the machines being not 100% efficient. This friction leads to the loss of energy in the form of heat, into the surroundings. Some of the supplied energy may be utilised to change the entropy (measure of randomness of the particles) of the system.
I really don’t know good luck
