Answer: The De broglie's wavelength is 1.45×10^-14m
Explanation:
Using De broglie's equation
λ= h/mv
Where h= Planck's constant = 6.6×10^-34Js
m= mass in kilogram = 3.8×10^-28kg
V= velocity = acceleration ×time =
2.4×10^7 ×5
V= 1.2×10^8m/s
λ= is the De broglie's wavelength
λ= 6.6×10^-34Js /(3.8×10^-28kg ×1.2×10^8)
λ= 1.45×10^-14m
Therefore ,De broglie's wavelength=
1.45×10^-14m
Answer:
A) the maximum acceleration the boulder can have and still get out of the quarry
B) how long does it take to be lifted out at maximum acceleration if it started from rest
Explanation:
A)
let +y is upward. look below at the free body diagram. the mass M refers to the combined mass of the boulder and chain.
the weight of the chain is: and maximum tension is
total mass and weight is :
∑
B)
maximum acceleration
using
to solve for t
Answer:
Its not A..
Explanation:
I chose A - was incorrect
Every speck of mass in creation is attracted to every other speck
by gravitational forces. Whether or not the forces of gravity have
any influence on the motion of the specks depends on their masses
and the distances between them. Gas molecules are not immune to
the forces of gravity, but they may be relatively unaffected by them,
just as human beings are relatively unaffected by the forces of
gravitational attraction between them.
