Answer:
The energy stored in the capacitor is 333.3 J
Explanation:
Energy stored in a capacitor = CV²/2
C = capacitance = 14 × 10⁻⁶F
V = 6.90 × 10³V
Energy = (14 × 10⁻⁶)(6.90 × 10³)²/2 = 333.27 = 333.3 J
Hope this Helps!!!
50 times 2.5 and them subract the product from 2500
I THINK THAT IS THE ANSWER
HOPE THIS HELPS!!!!!!! ;-)
Answer:
3.066×10^21 photons/(s.m^2)
Explanation:
The power per area is:
Power/A = (# of photons /t /A)×(energy / photon)
E/photons = h×c/(λ)
photons /t /A = (Power/A)×λ /(h×c)
photons /t /A = (P/A)×λ/(hc)
photons /t /A = (680)×(678×10^-9)/(6.63×10^-34)×(3×10^-8)
= 3.066×10^21
Therefore, the number of photons per second per square meter 3.066×10^21 photons/(s.m^2).
