The answer is downwards because the ball is pulling down the spring due to its weight
this has something to do with black body radiation and absorption
Answer:
I=
Explanation:
We are given that
Mass of rod=M
Length of rod=L
Mass of hoop=M
Radius of hoop=R
We have to find the moment of inertia I of the pendulum about pivot depicted at the left end of the slid rod.
Moment of inertia of rod about center of mass=
Moment of inertia of hoop about center of mass=
Moment of inertia of the pendulum about the pivot left end,I=
Moment of inertia of the pendulum about the pivot left end,I=
Moment of inertia of the pendulum about the pivot left end,I=
Moment of inertia of the pendulum about the pivot left end,I=
Moment of inertia of the pendulum about the pivot left end,I=
Answer:
Stellar Spectra Classification The patterns of lines detected in stellar spectra are used by astronomers to classify stars into spectral classes. These spectral classes are a measure of a star's surface temperature since the temperature of a star dictates which absorption lines are present in its spectrum.
