Afamous motorcycle company has just built its first electric model. like all vehicles, the purpose of the motorcycle is to put out kinetic energy. an illustration of motorcycle with a wide arrow away from it labeled electric energy 800 j and it splits into 3 arrows labeled kinetic energy ? j, heat 200 j, and friction 200 j. how much energy goes toward kinetic energy? 50 j 200 j 400 j 800 j

400 J

Explanation:

In any machine that exists part of its energy dissipates to the medium can dissipate in the form of heat, friction with the surface, among others

In this case energy is lost to the environment by friction and heat, when energy is lost in the medium it dissipates and the machine can no longer use it to operate.

if 200 J in the form of heat is lost from the total kinetic energy and 200 J in the form of friction

This amount of lost energy can no longer be used in the form of kinetic energy.

Then we must subtract the lost energy from the total initial energy to know how much kinetic energy we have available

The total kinetic energy that remains available is 400 J of the initial energy

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.

answer: option c.
