A positive charge of 5.10 µC is fixed in place. From a distance of 4.70 cm a from the fixed positive charge, a particle of mass 5.70 g and charge +4.00 µC is released from rest. What is the speed of the +4.00 µC when it is 8.10 cm away from the fixed positive charge? (in m/s)

What do elements in a family tend to share. a.) similar periods b.) similar groups c.) similar atomic symbols d.) similar chemical properties and characteristics

While the change in blank will remain the same during a collision, the force needed to bring an object to a stop can be blank if the time if collision is blank

When you see distant streetlights through smog, they look dimmer and redder than they do normally. but when you see the same streetlights through fog or falling snow, they look dimmer but not redder. use your knowledge of the interstellar medium to discuss the relative sizes of the particles in smog, fog, and snowstorms compared to the wavelength of light.
