Answer:
λ = 5.656 x 10⁻⁷ m = 565.6 nm
Explanation:
Using the formula of fringe spacing from the Young's Double Slit experiment, which is given as follows:
where,
λ = wavelength = ?
Δx = fringe spacing = 1.6 cm = 0.016 m
L = Distance between slits and screen = 4.95 m
d = slit separation = 0.175 mm = 0.000175 m
Therefore,
<u>λ = 5.656 x 10⁻⁷ m = 565.6 nm</u>
Answer:
Force = 6.25
so here correct option is a. 6.25
Explanation:
given data
resistance = 0.05 Ω
uniform magnetic field = 0.5 T
time = 0.1 s
to find out
maximum value of the force acting on the bar during that time
solution
we use here Faraday law of induction in the term of current
and solve here for I via the ohms law instead of the emf
That is end up by dividing by resistance
so here I will be
I = ..............1
I =
I = 25 A
and now l is length of 1 side of square when we solving for the force that is
Force = N*I²*B
Force = 1 ×25×0.5×0.5
Force = 6.25
so here correct option is a. 6.25
Answer:
The displacement of the spring, as measured from equilibrium, is 0.301 m
Explanation:
Hi there!
Using Hooke´s law, we can calculate the displacement of the spring:
F = -kx
Where:
F = restoring force exerted by the spring.
k = spring constant.
x = displacement of the spring.
The force exerted by the spring can also be calculated using the Newton law:
F = m · a
Where:
F = force.
m = mass of the object.
a = acceleration.
Then, combining both laws:
F = -k · x = m · a
-k · x = m · a
-339 N/m · x = 10.0 kg · 10.2 m/s²
x = 10.0 kg · 10.2 m/s² / -339 N/m
x = -0.301 m
The displacement of the spring, as measured from equilibrium, is 0.301 m
