Answer
given,
expression of Kinetic energy of rotating body
ω = 34.0 rad/s
Assuming mass of the particle equal to 13 Kg
and perpendicular distance from the particle to the axis is r = 1.25 m
now,
moment of inertia of particle = ?
from the given expression
..............(1)
we know
v = r ω
putting value in equation (1)
I = 20.3125 kg.m²
60,000 is 100 times as much as 600
To solve this problem we will apply the concepts related to the Doppler Effect. The Doppler effect is the change in the perceived frequency of any wave movement when the emitter, or focus of waves, and the receiver, or observer, move relative to each other.
Mathematically it can be described as
Where,
v = Speed of sound
f' = Reflected frequency
f = Emitted Frequency
= Speed of the object
Assuming that the speed of the medium is the speed of sound of 343m / s, we will then have that:
Answer:
Period = 6 seconds.
Explanation:
Given the following data;
Number of oscillation, n = 10
Time = 1 minute to seconds = 60 seconds
To find the period;
A period is the number of revolutions in a minute.
Substituting into the equation, we have;
Period = 6 seconds.
Answer:
Explanation:
The mass difference is
Δm = m2 - m1
56.936296 u - 56.935399 u
= 0.000897 u
The energy released by the electron-capture decay
E = Δmc²
( 0.000897 u) c² ( 931. 5 MeV /c²÷ 1 u)
= 0.8355555 MeV
