Explanation:
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
welp because of sites like brainly if they wnt an answer on a test they did not study for they try cheating and get the answer and the get plagarized
I think the answer is C
hope this helps :)
