A solar-powered vehicle developed at Massachusetts Institute of Technology can reach an average speed of 60.0 km/h. Due to the presence of Earth’s magnetic field, a
magnetic force acts on the electrons that move through the car’s circuitry. Suppose an
electron moves at 60.0 km/h perpendicular to Earth’s magnetic field. If a 2.0 x 10x22
N force acts on the electron, what is the magnetic field strength at that location?

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day

higher potential

explanation:

because it is in a high speed so it must move into a of high potential

conservation of mass

mass before something happens = mass afterwards
