Answer:
Explanation:
The period of a physical pendulum is:
The length of the leg is approximately the height of the person:
The period is:
Answer:
they stay shifted the same amount to the red
Explanation:
Redshift is given by
Where,
= Wavelength observed
= Wavelength emitted
Also
Transverse redshift is given by
v = Velocity of object
c = Speed of light =
So, if the velocity is constant the redshift remains the same
1. Changing voltage increases the current.
2. Adding more lightbulbs increase the resistance and the light bulbs become dimmer as the current has to be shared.
3. Yes its constant.
