How is a joule defined? A. It is the force needed to make an object with a mass of 1 kilogram accelerate by 1 kilogram per second squared.

B. It is the force needed to make an object with a mass of 1-kilogram travel 1 meter.

C. It is the work done when a force of 1 newton is applied to accelerate an object by 1 kilogram per second squared.

D. It is the work done when a force of 1 newton is applied to an object for a distance of 1 meter.

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

explanation:

a fuel engine ( known as a gasoline engine in american english )is an internal combustion engine with spark ignition, designed to run on petrol (gasoline) and similar volatile fuels.
