The energy produced by the headlamp at the end of 5 minutes is determined as 1,440 J.
<h3>
Energy supplied by the lamp</h3>
The energy supplied by the lamp is calculated as follows;
E = Pt
E = IVt
where;
- I is current = 0.4 A
- V is voltage = 12 V
- t is time = 5 mins = 5 x 60 s = 300 s
E = 0.4 x 12 x 300
E = 1,440 J
Thus, the energy produced by the headlamp at the end of 5 minutes is determined as 1,440 J.

The hot discharge gas from the refrigerant compressor is normally cooled and condensed at high pressure. This is then passed through an 'Expansion' valve which decreases the pressure to a low level causing expansion of the refrigerant liquid.
<span>The liquid partially vapourises causing a 'Joule's/Thompson' refrigeration effect' which decreases temperature of the refrigerant which then passes to an evaporator coil in the air circulation system of the building. </span>
<span>In the evaporator coil, the heat exchange between the cold refrigerant and the warm air of the building, vaporises and heats the refrigerant which returns to the compressor. </span>
<span>The cycle is repeated until the air temperature reaches the thermostat set-point and switches off the system. </span>
<span>As a Heat pump, the hot refrigerant gas is not evaporating and condensing. </span>
<span>From the compressor discharge, the hot gas is by-passing the cooler/condenser unit and the expansion valve and passes directly to the 'evaporator' coils but now, as the heating medium for the air circulation system where it's cooled by the heat exchange between the hot gas and the cooler air in the building and returns to the compressor in a continuous cycle. </span>
<span>A Thermostat in the system starts and stops the compressor motor according to the heat or cool temperature settings.</span>
Answer:
Technician B who says that low compression on a single cylinder will affect the engine’s cranking sound
Explanation:
if you have low compression in one cylinder, the engine will start but you'll likely experience misfires and your vehicle will run roughly.
It's only when you have no compression at all that the engine will not start.
The technician that said that low compression on a single cylinder will affect the engine’s cranking sound is correct.
Explanation:
The given data is as follows.
Fluid is water so, density 
Weight flow rate = 500 lbf/s = 2224.11 N/sec
Cross-sectional area (A) = 
= 0.05184 
Hence, weight flow rate will be given as follows.
w = 
2224.11 N/sec =
V = 
m/s
= 4.373 m/s
Thus, we can conclude that average velocity in the given case is 4.373 m/s.
An observable phenomenon that is commonly associated with a spinning object moving through a fluid.
