Acommunity in texas broadcasts public service announcements on tornado safety right before spring. why is this the most effective time to do so?
a)
it is the time of year when the temperature contrast is greatest between colliding polar and tropical air masses over the central united states.
b)
it is the time of year when the temperature contrast is the least between colliding tropical air masses over the central united states.
c)
it is the time of year when the temperature contrast is the least between colliding polar and tropical air masses over the central united states.
d)
it is the time of year when the temperature contrast is greatest between colliding tropical air masses over the central united states.

The protons in a nucleus are approximately 2 ✕ 10^−15 m apart. consider the case where the protons are a distance d = 1.93 ✕ 10^−15 m apart. calculate the magnitude of the electric force (in n) between two protons at this distance.
