Answer:
Explanation:
Given
Mass of solid uniform disk 
radius of disk 
mass of lump 
distance of lump from axis 
Moment of inertia is the distribution of mass from the axis of rotation
Initial moment of inertia of disk 
Final moment of inertia 
=Moment of inertia of disk+moment of inertia of lump about axis
If you think about the colors of the rainbow red, orange, yellow, green, blue, indigo, and violet. That list of colors shows you the spectrum of visible light and the further right (towards violet) you go the more energy the waves have while the more left (towards red) you go the less energy the waves have. wavelength and energy are inversely proportional meaning that as energy goes up, wavelength goes down. therefore the more right (towards violet) you move in the spectrum, the smaller the wavelengths get.
Answer:
a. The magnitude of the magnetic field is changing.
b. The magnetic field is changing direction with respect to the bracelet.
c. The bracelet is moving in the magnetic field.
Explanation:
Magnetic flux is a measure of the total magnetic field that passes through a given area. The value of the flux depends on the magnitude of the magnetic field, the area it crosses and its orientation relative to the magnetic field. Therefore, all three reasons are valid.
