Tap water conducts electricity because 1. water is a polar molecule; the charged ends inherently conduct electricity. 2. tap wat

er has many ions dissolved in it, which are responsible for the conduction of electricity. 3. water is held together by weak dispersion forces, which allow the molecules to move readily and conduct electricity. 4. the hydrogen bonds in liquid water provide a bridge for the movement of electrons.

Answer: Option (2) is the correct answer.

Explanation:

It is known that tap water acts as an electrolyte because there are a number of ions present in it. As electricity is the flow of ions or electrons therefore, a solution which contains the ions is able to conduct electricity.

For example, ions present in tap water are Mg^{2+}, Na^{+}, Ca^{2+} etc.

Thus, we can conclude that tap water conducts electricity because tap water has many ions dissolved in it, which are responsible for the conduction of electricity.

A bag of sugar weighs 3.50 lb on Earth. What would it weigh in newtons on the Moon, where the free-fall acceleration isone-sixth
Alex73 [517]

Answer:

F_{Earth}= 15.57 N

F_{Moon}= 2.60 N

F_{Uranus}= 16.98 N

The mass of the bag is the same on the three planets. m=1.59 kg

Explanation:

The weight of the sugar bag on Earth is:

g=9.81 m/s²

m=3.50 lb=1.59 kg

F_{Earth}=m·g=1.59 kg×9.81 m/s²= 15.57 N

The weight of the sugar bag on the Moon is:

g=9.81 m/s²÷6= 1.635 m/s²

F_{Moon}=m·g=1.59 kg× 1.635 m/s²= 2.60 N

The weight of the sugar bag on the Uranus is:

g=9.81 m/s²×1.09=10.69 m/s²

F_{Uranus}=m·g=1.59 kg×10.69 m/s²= 16.98 N

The mass of the bag is the same on the three planets. m=1.59 kg

Because of barriers and obstructions, you can see only a tiny fraction of a standing wave on a string. You do not know, for inst
chubhunter [2.5K]

Answer:

(1) Sure, the frequency is 1000 Hz.

Explanation:

Frequency = wave speed ÷ wave distance

wave speed = 100 m/s

wave distance = 10 cm = 10/100 = 0.1 m

Frequency = 100 ÷ 0.1 = 1000 Hz

Which element easily loses one electron to form a positive ion?
olga nikolaevna [1]

Answer/Explanation: As mentioned above, the characteristic chemical property of a metal atom is to lose one or more of its electrons to form a positive ion. However, certain metals lose electrons much more readily than others. In particular, cesium (Cs) can give up its valence electron more easily than can lithium (Li).
