How strong is the repulsive force exerted on two point charges that each carry 1.0 e-6 c of negative charge and are 0.30 meters apart? coulomb’s constant is 9.0 e9 n*m^2/c^2 remember to identity all of your data, write the equation, and show your work.

Coulomb's law states that the force between two charged particles is directly  proportional to the multiplication of the two charges and inverse with the square of the distance between them.

Mathematically,

where: F is the force in (N), are the charge of the two particles in (C), r is the distance between them and k is Coulomb's constant

Thus

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
