What is the tension in a cord 10m long if a mass of 5kg is attached to it and is being spun around in a circle at a speed of 8m/s? 50N 28N 32N 67N​

Which material produces static charge when rubbed?

The charge on an electron is 1.60218 × 10−19 c and its mass is 9.10939 × 10−31 kg. how strong a magnetic field must be experienced by the electron if its path is a circle of radius 5.5 cm? answer in units of t.

When electrons are added to the outermost shell of a carbon atom, it forms--an anion that has a larger anion that has a smaller cation that has a larger cation that has a smaller radius.
