    Skydiving: Friction, Velocity, and Parachutes

    Evening everyone I wanted to see if my answer would be considered adequate for the question? If its not please suggest anything i could add to it, my answer is: The skydiver will accelerate as soon as they exit the aircraft, as this happens, the frictional force increases and the forces are...

    Need to know if my answers are correct (electric field questions)

    An alpha particle of 3.2 x 10^-19C (to the power -19) accelerates from rest between two oppositely charged plates starting from the +ve plate. The electric field between the plates is uniform and equal to 39000 N/C. The distance between the plates is 4.50 x 10^-3m (to the power -3). a)...

    Explain the term permittivity and how this affects force

    I put Coulomb's Law and the formula F=K (Q1Q2 over Resistance Squared) Where K is a constant and its formula The electric permittivity and its equation Absolute permittivity and lastly i put the reasons why dielectric materials are used in capacitors have i missed anything?

    Explain the term permittivity and how this affects force

    Hey everyone I just started an engineering course and have been given a few questions but I am struggling with this one as i feel that i have not included all the info that should be there. Can someone tell me briefly what they would explain the term permittivity as and how they think it would...
