A particle with a charge of −1.24×10−8C is moving with instantaneous velocity v→ = (4.19×104m/s)i^ + (−3.85×104m/s)j^ . What is the force exerted on this particle by a magnetic field
(a) B = (1.40T)ıˆ and
(b) B =(1.40T)kˆ ?

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.

given values:

mass = 0.3 kg.

it is a negative acceleration

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
