4-4 our galaxy is about 105 light-years across, and the most energetic particles known have an energy of about 1019 ev. how long would it take a proton with this energy to traverse the galaxy as measured in the rest frame of (a) the galaxy? (b) the particle?

when cloud cover increases then the suns ray's which provides the earth with light and warmth gets covered due to the due to the suns ray's being blocked, the temperature in that region

therefore to conclude i would like to say that,

=more the cloud cover, the lesser the

happy to

pls mark as brainliest.

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
