Answer: Apple at point D
Explanation:
Potential energy is the energy possessed by an object by virtue of its position.
m= mass of object
g = acceleration due to gravity =
h = height of an object
Thus as can be seen from the relation, potential energy is directly proportional to the height of an object, the apple with maximum height, at point D will have maximum potential energy.
Answer:
2.7 J
Explanation:
The energy of one photon is given by
where
h is the Planck constant
f is the frequency
For the photons in this problem,
So the energy of one photon is
The number of photons contained in 1.0 mol is
(Avogadro number)
So the total energy of photons contained in 1.0 mol is
Answer:
Energy stored in the capacitor is
Explanation:
It is given that,
Charge,
Potential difference, V = 36 V
We need to find the potential energy is stored in the capacitor. The stored potential energy is given by :
U = 0.000027 J
So, the potential energy is stored in the capacitor is . Hence, this is the required solution.
