Center of low pressure are called
a) antics clones
b) air masses
c) jet streams
d) cyclones

The correct answer is option D.

Explanation:

A surface of  low pressure center is the point or space where pressures measured to be the lowest in comparison to its surroundings.Low pressure centers often represent the center of mid-latitude cyclones.

Anti cyclones is a weather phenomena where atmospheric pressure is higher at the center around which air moves or circulates at slow speed.

Air mass of the body of air with uniform humidity pressure and temperature.

Jet-streams are fast flowing air currents found in the atmosphere around 10 km above the surface of earth.

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~
