I can not give you the direct answer but I can give you some ideas. The videos that go viral have an effect that makes peoples ideas clear and shows what people are into and then more people can get to know about these things.
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
you could say that you would put watermarks in some frames so you can prove u made it yourself
