2) A positive charge will attract another positive charge.
3) Protons are negatively charged.
4) Insulators allow electricity to flow through them.
5) Current is the flow of protons.
6) Current is measured in volt
7) in the factory model of circuits the shop represents the battery
8) in a series circuit the current increases if you add more components.
9) voltage is measured in volts using an ammeter
10) you can work out the energy from charge x time

Help please i will mark brain list !!!

7.45 a student is interested in the aerodynamic drag on spheres. she conducts a series of wind tunnel tests on a 10-cm-diameter sphere. the air in the wind tunnel is at 50 â°c and 101.3 kpa. she presents the results of her tests in the form of a correlation, đť’ź = 0.0015v1.92, where đť’ź is the drag force in newtons and v is the velocity in m/s. another student realizes that the results would have been more effectively presented in terms of dimensionless parameters, say, î  1 = f (î  2) = c î  a2 , where î  1 and î  2 are dimensionless parameters and c and a are constants. what are the most appropriate dimensionless parameters (î  1 and î  2) and the corresponding values of c and a? what would be the drag on a 2-cm-diameter sphere placed in a 1-m/s, 20 â°c water stream?
