Answer:
B. 16 kJ
Explanation:
Energy = VIt.............. Equation 1
Where V = Voltage, I = Current, t = time
Given: V = 5.0 V, I = 1.5 A, t = 1 h = 3600 s.
Substitute these values into equation 2
E = 5.0(1.5)(3600)
E = 27000 J
E = 27 kJ.
Amount of energy left = 43 kJ - 27 kJ
Amount of energy left = 16 kJ.
Hence the right option is B. 16 kJ
Answer:
Explanation:
Set the equations for work and kinetic energy equal to each other. Work equals force times distance and kinetic energy equals one-half the mass of the object times its velocity squared, so F_d = (m_ ÷ _2)_v2. Substitute the measurements for force, distance and mass into the equation.
O no,O no,O no actualy the point is that I don’t know the answer to the question

I hope i answered your Question.
The average human walking speed at crosswalks is about about 3.1 miles per hour (mph) or 5.0 kilometers per hour (km/h).
In order to calculate the time needed to walk 2000 miles, we should divide 2000 with the average speed.
2000 miles / 3.1 miles per hour= 645,161 hours
It takes 645 hours to walk 2000 miles.
