b. weight of the atom.
c. mass of the atom.
d. sum of the protons and neutrons in an atom.
true or false
I got bored and decided to play the password game-
Rule 18 is: The elements in your password must have atomic numbers that add up to 200.
The current elements I have are: Ne, V, W, Re
I don't know what any of this is- I failed chem but please help ;-;
Also ignore my username, I haven't used this account in like two years-
If I were to create a password out of elements of the periodic table such that the sum of them would add upto 200 ,
I would be using these elements
Berillium = 4 [Be]
Sulphur = 16 [S]
Uranium = 92 [U]
Nitrogen = 7 [N]
Hydrogen = 1 [H]
Iodine = 53 [I]
Neon = 10 [Ne]
and the password would be " Be SUNSHHINe " which adds upto [4 + 16 + 92 + 7 + 16 + 1 + 1 + 53 + 10 = 200 ].
The given elements' atomic numbers add up to 182. To meet the requirement of Rule 18 (total of 200), you need elements that add up to 18 (200-182). By adding Fluorine (F) and Argon (Ar), both with atomic numbers of 9, you can reach the required total.
The periodic elements provided in the question are Neon (Ne), Vanadium (V), Tungsten (W), and Rhenium (Re). Their respective atomic numbers are 10, 23, 74, and 75. If you add these atomic numbers together, the total is 182. This means you need elements that will add up to 18 (200-182) to meet the requirement of Rule 18. Adding Fluorine (F) with an atomic number of 9 and Argon (Ar) with an atomic number of 9 can help you reach this required total.
To summarize:
Neon (Ne) = 10,
Vanadium (V) = 23,
Tungsten (W) = 74,
Rhenium (Re) = 75,
Total so far = 182,
Your password needs atomic numbers total = 200,
You're short of = 200 - 182 = 18.
Adding Fluorine (F) with atomic number 9 and Argon (Ar) also with atomic number 9 gives = 9+9 = 18.

B. lightning striking as the storm forms.
C. the movement of continental tropical air masses.
D. the action of waves in warm ocean waters.
Huge storms called hurricanes have winds that rotate at a rate of 74 miles per hour. The spinning wind blows with a scary force across the tropical waters' warm surface. A hurricane’s energy comes from the condensation of large amounts of water vapor. The correct option is A.
Hurricanes are fueled by thunderstorms and warm ocean waters. Hurricanes frequently begin as tropical waves, which are low-pressure systems that pass over moist regions of the tropics and may intensify shower and thunderstorm activity. Hurricanes form over the ocean.
The eye, eyewall, and outer region are the three main components of a mature hurricane. A vertical cut through a mature hurricane's center.
Thus the correct option is A.

b. a compass needle.
c. a circuit.
d. poles.
Answer:
d. poles
Explanation:
Magnetic field created by a solenoid:
The magnetic field created by a solenoid is increased by increasing the intensity of the current, by increasing the number of turns and by introducing a piece of iron inside the coil (electromagnet).
Solenoid coil with air core constructed with bare copper wire spirally wound and protected with insulating varnish. If we supply this coil with electric current using any source of electromotive force, such as a battery, for example, the flow of the current that will circulate through the coil will lead to the appearance of a magnetic field of a certain intensity around it.
Solenoid coil to which a metal core such as iron (Fe) has been introduced. If we compare the previous coil with air core with the coil of this illustration, we will see that now the lines of magnetic force are much more intensified as they have become an electromagnet.
