The Sankey diagrams below show the energy transfers in two light bulbs. How is the input energy carried to the light bulb's energy stores?

the answer is a)

mark brainliest

c

explanation:

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
