If you are talking about gravitational potential energy, then the ONLY way to either increase OR decrease it is to raise or lower your height. The higher you are off the ground the greater your PE, the closer you are to the ground, the lower your PE
Answer:
Part a)
Final charge on C : q = 1.875
Part b)
Ratio for A = 6 : 1.25
Ratio for B = -1 : 1.875
Ratio for C = 0
Explanation:
When two identical metal sphere are connected together then the charge on them will get equally divided on both after connecting them by conducting wire
So here we have
Step 1: We connected A and B and then separate them
so we have
Step 2: We connected A and C and then separate them
so we have
Step 3: We connected B and C and then separate them
so we have
Answer:
4.4 MJ
Explanation:
We are given that an automobile with an internal combustion engine converts the potential energy of gasoline into kinetic energy of the moving piston.
1 kg of gasoline gives energy=44 MJ.
Average internal combustion engine =10 % efficient
We have to find how much potential energy is converted into energy to run the pistons.
10% of 44 =
Since 10% is efficient of internal combustion.
Therefore, 4.4 MJ potential energy is converted into energy to run the pistons.
