Answer:
D. Copper
Explanation:
Copper has the best electrical conductivity of any metal, except silver. A good electrical conductivity is the same as a small electrical resistance.

All waves have an amplitude, wavelength, and frequency.
Amplitude is how far away the wave moves from its resting place. When drawn on a graph, the amplitude is the distance between the upper (crests) and lower (troughs) points and their center on the wave.
Wavelength is the distance two crests or troughs are away from each other.
Frequency is the number of waves produced in a set amount of time. The unit used to measure frequency is Hertz (Hz).
With sound waves, the frequency determines the pitch. The higher the frequency, the higher the pitch, and vice versa. So, a bass drum, which has a low pitch, would have a lower frequency than a mosquito's whine, which is very high pitched.
Light waves are actually electromagnetic waves. Their frequency determines what kind of wave they are, whether it's gamma rays, ultraviolet, x-rays, or something else.
The volume of water in the larger balloon is 8 times greater than in the smaller balloon
We'll begin by calculating the volume of each balloon.
<h3>For smaller balloon:</h3>
- Radius (r) = 3 cm
- Pi (π) = 3.14
- Volume (V) =?
V = 4/3 πr³
V = 4/3 × 3.14 × 3³
<h3>V = 113.04 cm³</h3>
<h3>For larger balloon:</h3>
- Radius (r) = 6 cm
- Pi (π) = 3.14
- Volume (V) =?
V = 4/3 πr³
V = 4/3 × 3.14 × 6³
<h3>V = 904.32 cm³</h3>
Finally, we shall determine how much greater the larger balloon is to the smaller balloon
- Volume of smaller balloon = 113.04 cm³
- Volume of larger balloon = 904.32 cm³
- Greatness =?
Greatness => large / small
Large / small = 904.32 / 113.04
Large / small = 8
Cross multiply
<h3>Large = 8 × small </h3>
Therefore, the larger balloon is 8 times greater than the smaller balloon.

Independent variable
The independent variable is the variable that is controlled and manipulated by the experimenter. For example, in an experiment on the impact of sleep deprivation on test performance, sleep deprivation would be the independent variable.
