The bowling ball is at rest, so it only has gravitational potential energy.
Ug = mgy
Ug = (2)(9.8)(40) = 784 J
Need any more help?
The answer would be false
Answer:
It can be concluded that the star is moving away from the observer.
Explanation:
Spectral lines will be shifted to the blue part of the spectrum if the source of the observed light is moving toward the observer, or to the red part of the spectrum when is moving away from the observer (that is known as the Doppler effect).
The wavelength at rest for this case is 434 nm and 410 nm (, )
Since, (444nm) is greater than (434 nm) and (420nm) is greater than (410 nm), it can be concluded that the star is moving away from the observer
Answer: Kinetic Molecular Theory claims that gas particles are in continuous motion and completely demonstrate elastic collisions. Kinetic Molecular Theory can be used to describe the rules of both Charles and Boyle. A series of gas particles only has an average kinetic energy that is directly proportional to absolute temperature.
