Answer:
1.7 J
Explanation:
The energy carried by a single photon is given by
E=hf
where h is the Planck's constant and f is the frequency of the photon.
The photon of our exercise has a frequency of f=1.7 \cdot 10^{17} Hz, therefore its energy is
E=hf=(6.63 \cdot 10^{-34}Js)(1.7 \cdot 10^{17} Hz)=1.1 \cdot 10^{-16} J
Answer:
0.08 ampere
Explanation:
Power = voltage x current
W = v x I
Given
Power = 10.0 w
V = 120v
I = ?
Therefore
10.0 = 120 x I
Divide both sides by by 120
10.0/120 = 120/120 x I
0.08 = I
I = 0.08 ampere
