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.

Why is rain likely when warm, moisture-laden air meets cold air? a) the lighter warm air will rise and cool down, causing condensation and rain. b) the cold air moves faster and pushes the warm air away, causing condensation and rain. c) the moisture in the warm air condenses on contact with the cold air, causing rain to fall. d) the cold air mixes with the warm air, reducing its temperature causing moisture to condense.

The dipole moment of the water molecule (h2o) is 6.17x10^-30 c. m. consider a water molecule located at the origin whose dipole moment p points in the +x-direction. a chlorine ion ( of charge-1.60x10^-19c , is located at x=3.00x10^-9m . assume that is much larger than the separation d between the charges in the dipole, so that the approximate expression for the electric field along the dipole axis can be used. a) find the magnitude of the electric force that the water molecule exerts on the chlorine ion. b) what is the direction of the electric force. -x-direction or +x-direction c) is this force attractive or repulsive?
