Ryan wants to transform electrical energy into light energy. he decides to build a complete circuit that will operate a light bulb. what materials does he need? a) a battery, wire, plastic clips, and a bulb b) a battery, string, plastic clips, and a fan c) a source of electrical energy, wire, metal clips, and a bulb d) a source of electrical energy, string, metal clips, and a bulb

C)a source of electrical energy, wire, metal clips, and a bulb

Explanation:

Since Ryan want to convert electrical energy to light energy so here we need a device which will give us electrical energy and also we need a source of light.

So here here in this experiment we need to convert this electrical energy into light energy so we need to connect the electrical bulb with the source of electrical energy so that the bulb will glow and give us light energy

Now here in order to connect the bulb with the battery we need connecting wires and metal clips to connect bulb with the battery or electrical energy source.

so here correct answer is

C)a source of electrical energy, wire, metal clips, and a bulb

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
