We can make pretty good guesses for their masses, but kinetic energy also depends on their speeds, which we don't know, and may change.
As an example ... If the truck, the van, the car, and the bike are all parked at the mall, then a scampering mouse has more kinetic energy than all of them combined.
As the question stands, no answer is possible.
Answer:
1.15 rad/s²
Explanation:
given,
angular speed of turntable = 45 rpm
=
=
time, t = 4.10 s
initial angular speed = 0 rad/s
angular acceleration.
Hence, the angular acceleration of the turntable is 1.15 rad/s²
As you move closer to the star, it appears brighter. Brighter magnitudes are lower numbers, so the star's apparent magnitude would decrease.
I believe the correct answer from the choices listed above is the second option. With this information, he was able to conclude that the beam was negatively charged. His cathode ray<span> tube experiments led to a very important scientific discovery, the electron. Hope this answers the question.</span>
