The pressure on the windows was generated by air pushing on the windows, which is the average the air molecules are applying over the surface area of the glass. velocity acceleration force density

Force

Explanation:

The pressure is defined as the ratio between the force applied on a surface divided by the area of the surface:

where F is the force applied and A is the area of the surface.

Therefore, in this specific case, the pressure on the window is generated by the air pushing on the window, and that pressure is given by the average force of the air molecules divided by the surface area of the glass.

Pressure is NOT a Velocity, an Acceleration, a Force, or a Density.

Pressure is the average force per unit area the air molecules are applying over the surface area of the glass.

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.

a small object of mass 3.66 g and charge -17.6 µc is suspended motionless above the ground when immersed in a uniform electric field perpendicular to the ground. what are the magnitude and direction of the electric field?
