How would you connect these items to make a circuit in order to power a light bulb? step by step explanation

Making a Circuit:

1. Connect one end of each wire to the screws on the base of the light bulb holder. (If you’re using foil, ask an adult to help you unscrew each screw enough to fit a foil strip under it.)

2. Connect the free end of one wire to the negative (“-“) end of one battery. Does anything happen?

3. Attach the free end of the other wire to the positive (“+”) end of the battery. Now what happens?

Adding Power :

1. Disconnect the battery from your circuit. Stand one battery so that the “+” end is pointing up, then set the other battery next to it so that the flat “-” the end is pointing up. Tape around the middle of the batteries to hold them together.

2. Set a paperclip across the batteries so that it connects the “+” end of one to the “-” end of the other. Tape the paperclip in place with a narrow piece of tape (do not tape over the metal battery ends).

3. Turn the batteries over and tape one end of a paper clip onto each of the batteries. Now you can connect one wire to each paper clip. (The bottom of the battery pack should only have one paper clip – do not connect a wire to it.)

4. Connect the free ends of the wires to the light bulb.

(Note: Instead of steps 1-3, you can use two batteries in battery holders and connect them together with one wire.)

the answer is   c.) 1575 j.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
