Answer:
Explanation:
The De Broglie's wavelength of an object is given by:
where
h is the Planck constant
m is the mass of the object
v is the speed of the object
In this problem, we have:
is the mass of the pellet
is the speed of the pellet
Substituting into the equation, we find the wavelength of the pellet:
Answer:
The displacement is 33 m due west
Explanation:
From the question we are told that
The first displacement due east is
The displacement due west is
The second displacement due east is
Generally the displacement is mathematically represented as
=>
=> Note [-ive] represents west [+ive] represents east
Which means that the displacement is 33 m due west
Answer:
M = 222 fringes
Explanation:
given
λ = 559 n m = 559 × 10⁻⁹ m
radius = 0.026 mm = 0.026 ×10⁻³ m
length of the glass plate = 22.1 ×10⁻² m
using relation
= 221.79
= 221 (approx.)
hence no of bright fringe
M = m + 1
= 221 +1
M = 222 fringes
Answer:
The position of the spring in terms of g, m & k is
Explanation:
Stiffness of the spring = k
Mass = m
When a mass m is attached with the spring then spring stretched. in that case the force exerted on the spring is equal to weight of the mass attached.
⇒ Force exerted on the spring F = k x
⇒ m g = k x
⇒
This is the position of the spring in terms of g, m & k.
The formula for energy of motion is KE = .5 x m x v^2
Ke= Kinetic Energy in Joules
m = Mass in Kilograms
v = Velocity in Meters per Second
