Answer:
λ2 < λ1
Explanation:
- Young's experiment of interference of light when passed through a slit has determined a result. We will use an expression derived from the results that relates wavelength and and the spread of the interference pattern using:
sin (Q) = n*lambda / d
Where,
n is the order of fringe about the central order
lambda is the wavelength of light
d is the space between grating
Q is the angle between the two successive interference fringe
- So in our case using a light of wavelength lambda 2 the pattern got closer together or we could say that angle Q got smaller. According to the relationship given we can see as angle Q decreases when lambda decreases. So we can conclude that λ2 < λ1.
For one person standing at a distance of 1.57 m from the center, the carousel has an angular velocity of 0.512 rad/s, the person's mass is mathematically given as
m = 24.2 kg
<h3>What is the person's mass?</h3>
Generally, the equation for the conservation angular momentum is mathematically given as
(I + m * r0^2) * w0 = (I + m * r^2) * w^2
Therefore
(105 + m * 1.78^2) * 0.517 = (105 + m * 0.524^2) * 0.841
m = 24.2 kg
In conclusion, the mass
m = 24.2 kg

The 'Bulge', the 'Disk', the 'Spiral Arms', and the 'Halo' those are four parts of a spiral galaxy. Try finding out the many different types of galaxies to understand which is which.
Answer:
Explanation:
Given that,
Width of a one dimensional potential box, 
The energy of a particle in one dimensional box is given by :
h = Planck's constant
m = the mass of the proton
For minimum kinetic energy, n = 1
So, the minimum kinetic energy of the neutron is 
. Hence, this is the required solution.
Answer:
v = 45.37 m/s
Explanation:
Given,
angle of inclination = 8.0°
Vertical height, H = 105 m
Initial K.E. = 0 J
Initial P.E. = m g H
Final PE = 0 J
Final KE = 
Using Conservation of energy
v = 45.37 m/s
Hence, speed of the skier at the bottom is equal to v = 45.37 m/s
