From Ohm's Law, Resistance = (voltage) / (current)
The resistance is <em>233,333 and 1/3</em><em> </em><em>ohms</em>.
Answer:
Electric force, F = 20.16 N
Explanation:
It is given that,
Charge on gold nucleus,
An electron is sent at high speed toward a gold nucleus,
Distance between electron and gold nucleus,
We need to find the electric force acting on the electron. The formula for electrostatic force is given by :
F = 20.16 N
The electric force acting on the electron is 20.16 N. Hence, this is the required solution.
Answer:
θ = 34.77°
Explanation:
From diffraction equation:
where,
m = order of diffraction
λ = wavelength of light used
d = slit separation
θ = angle
Therefore, for initial case:
m = 2
λ = 600 nm = 6 x 10⁻⁷ m
d = slit seperation = ?
θ = angle 20°
Therefore,
Now, for the second case:
m = 5
λ = 600 nm = 6 x 10⁻⁷ m
d = slit seperation = (1.5)(3.5 x 10⁻⁶ m) = 5.26 x 10⁻⁶ m
θ = angle = ?
Therefore,
<u>θ = 34.77°</u>
The answer to the question is A.
