Explanation:
Given that,
The distance between two conducting plates is 7 cm.
The difference in potential between the plates is 560 V.
To find,
We need to tell is the positive or the negative plate at the higher potential?
Solution,
We know that the electric potential is defined as the work done in moving a test charge from one position to another. So, the positive plate is always at the higher potential.
Hence, this is the required solution.
Answer:
The mass of the copper is 3.00kg
Explanation:
Explanation:
Objects like apples, wood, and sponges are less dense than water. They will float. Many hollow things like empty bottles, balls, and balloons will also float. That's because air is less dense than water.
Answer:
Work, W = F * d, and
Work = change in kinetic energy, so W=deltaKE.
Hence,
deltaKE=F * d
(1/2)*m*v^2 =F * d
d=[(1/2)*m*v^2]/F
d=[(1/2)*0.6*20^2]/5
d=24 m.
Explanation:
Work = change in kinetic energy, so W=deltaKE.
