Answer:
7) Electrical Energy used = 5000 J
8) Check below for answer and explanation
Explanation:
7) Let the Sound Energy Produced = SE
Electrical Energy = EE
Sound energy produced, SE = 1000 J
% of Electrical energy converted to sound = 20%
SE = 20% of EE
SE = (20/100) * EE
1000 = 0.2 EE
EE = 1000/0.2
EE = 5000 J
Electrical Energy used = 5000J
8) The vehicle's efficiency = 18%
Energy loss = 82%
The 82% energy loss in the vehicle can be due to the following reasons:
a) Heat generated by the exhaust of the vehicle
b) Noise generated by the vehicle
c) Frictional force in the engine
d) Combustion
A vector format, such as postscript or svg!
Vector formats do not use pixels and therefore can be scaled and zoomed without ever becoming pixelated. Note that when the logo is actually used (e.g., on a web-site), it will typically be rendered as a bitmap (e.g., PNG image) of a certain size (number of pixels).
