The magnetic field of the wire will be directed towards west. Using right thumb rule one can get the direction of field lines.
B. my town is powered by electricity that is generated by the energy from the flow of water through a large dam.
The water from the large dam is example of renewable energy. It can be replenished through rainfall cycle, so it is a renewable form of energy.
some ball when you bounce it it comes back up but according to gravity the energy goes away
Answer:
3.25 × 10^7 m/s
Explanation:
Assuming the electrons start from rest, their final kinetic energy is equal to the electric potential energy lost while moving through the potential difference (ΔV)
Ek = 1/2 mv2 = qΔV .................. 1
Given that V is the electron speed in m/s
Charge of electron = 1.60217662 × 10-19 coulombs
Mass of electron = 9.109×10−31 kilograms
ΔV = 3.0kV = 3000V
Make V the subject of the formula in eqaution 1
V = sqr root 2qΔV/m
V = 2 × 1.60217662 × 10-19 × 3000 / 9.109×10−31
V = 3.25 × 10^7 m/s
