Answer: 3.76 mm
Explanation: The formulae that defines the position of a nth fringe from the center of a double slit interference experiment is given below as
y =R×mλ/d
Where y = distance between the nth fringe and the center
R = distance between slits and screen = 1.71 m
m = position of fringe = 1
d = distance between slits = 0.254 mm = 0.000254m
λ = wavelength of light = 559 nm = 559×10^-9m
By substituting parameters, we have that
y = 1.71×1×559×10^-9/0.000254
y = 0.00000095589 / 0.000254
y = 0.00376m = 3.76 mm
The energy converted is 48 Joules
<h3>How to determine the energy</h3>
We have the formula for energy in a circuit as
Energy = Power × time
Power = I^2 R
Current, I = 2.0 A
time = 1 minute
Resistance = 12 Ohm
Substitute into the formula
Power = 2 × 2 × 12
Power = 48 Watts
Energy = 48 × 1
Energy = 48 Joules
Thus, the energy converted is 48 Joules

Answer:
Explanation:
Electric field between plates
V / d
= 170 / ( 2 x 10⁻² )
= 8500 N/C
Force on electron in this field
= 8500 x 1.6 x 10⁻¹⁹
= 13600 x 10⁻¹⁹ N
Acceleration
= 13600 x 10⁻¹⁹ / 9.1 x 10⁻³¹
a = 1494.5 x 10¹² m /s²
s = .1 x 10⁻² m
v² = u² + 2as
= (2.9x 10⁵)²+ 2 x 1494.5 x 10¹² x .1 x 10⁻²
= 8.41 x 10¹⁰ + 299 x 10¹⁰
= (8.41 + 299 ) x 10¹⁰
v = 17.53 x 10⁵ m /s
The formula that can be used to obtain a convergent series is given by;
a/1 – r.
<h3>What is a series?</h3>
In mathematics, we define a series as sum of numbers which could be convergent or divergent. In a convergent series, the summation of the numbers approaches a given value.
