Answer:
Explanation:
Frequency of 3 x 10¹⁵ , wavelength = 3 x 10⁸/3 x 10¹⁵ = 10⁻⁷ m = 1000A.
Energy in eV = 12375/1000 = 12.375 eV.
Maximum kinetic energy of ejected electrons = 6.1 eV
Work function = 12.375 - 6.1 = 6.275 eV.
Fly in a straight line unless an outside force changes its course because i tried it once in a baseball game that my mommy rekt me in.
Answer:
The current across the resistance is 0.011 A.
Explanation:
Total resistance, R = 25 ohms
Total current, I = 100 mA = 0.1 A
Let the voltage is V.
By the Ohm's law
V = I R
V = 0.1 x 25 = 2.5 V
Now the resistance is R' = 220 ohm
As they are in parallel so the voltage is same. Let the current is I'.
V = I' x R'
2.5 = I' x 220
I' = 0.011 A
