Answer : Total energy dissipated is 10 J
Explanation :
It is given that,
Time. t = 10 s
Resistance of the resistors, R = 4-ohm
Current, I = 0.5 A
Power used is given by :
Where
E is the energy dissipated.
So, E = P t.............(1)
Since, 
So equation (1) becomes :
So, the correct option is (3)
Hence, this is the required solution.
85 N - 40 N = 45 N
And depending on direction the greater force is being pulled towards
Answer:
1. What type of wave is sound?
2.Does sound need a medium to travel through?
3. What are the properties of sound waves?
Explanation:
1. The type of waves sound are is mechanical waves.
2. Sound needs a solid, liquid or gas (material medium) to travel through.
3. I believe they are wavelength, amplitude, frequency, time period and velocity.
I apologize if it is incorrect-
I hope it helps! Have a great day!
