Why does carpet tend to produce differences in static electricity more that hardwood or tile floors

Physics
1 answer:
Makovka662 [10]4 years ago
4 0

Answer:

This is because the rubbing releases negative charges, called electrons, which can build up on one object to produce a static charge. For example, when you shuffle your feet across a carpet, electrons can transfer onto you, building up a static charge on your skin.

Explanation:

This is because the rubbing releases negative charges

A wave with a speed of 437 m/s has a frequency of 28 hertz. What is the length of the wave?
Natasha2012 [34]

Answer: 15.6 metres

Explanation:

Given that:

length of wave (λ)= ?

Frequency of wave F = 28 Hertz

Speed of wave (V) = 437 m/s

The wavelength is the distance covered by the wave in one complete cycle. It is measured in metres, and represented by the symbol λ.

So, apply V = F λ

Make λ the subject formula

λ = V / F

λ = 437 m/s / 28 Hertz

λ = 15.6 m

Thus, the length of the wave is 15.6 metres

An lc circuit oscillates at a frequency of 2000 Hz. What will the frequency be if the inductance is quadrupled?
Irina-Kira [14]
<h2>Answer:</h2>

An LC circuits if formed by an inductor and a capacitor. The charge on the capacitor and the current through the inductor both vary sinusoidally with time. Also, energy is transferred between magnetic energy in the inductor and electrical energy in the  capacitor. But <em>what happens with the frequency if the inductance is quadrupled? </em>that is, if initially the inductance is L and the frecuency f=2000Hz if now L_{New}=4L What will the frequency be? Well, we know that the frequency, inductance and capacitance are related as:

f=\frac{1}{2\pi}\sqrt{\frac{1}{LC}}

and this equals 2000Hz. If now L is quadrupled:

f_{1}=\frac{1}{2\pi}\sqrt{\frac{1}{4LC}}=\frac{1}{2\pi}\sqrt{\frac{1}{4}}\sqrt{\frac{1}{LC}} \\ \\ \therefore f_{1}=(\frac{1}{2})\frac{1}{2\pi}\sqrt{\frac{1}{LC}} \\ \\ \\ Since \ f=\frac{1}{2\pi}\sqrt{\frac{1}{LC}} \ then: \\ \\ f_{1}=\frac{1}{2}f \therefore f_{1}=\frac{2000}{2} \\ \\ \therefore \boxed{f_{1}=1000Hz}

<em>Finally, if L is quadrupled the frequency is half the original frequency and equals 1000Hz</em>

Which condition must be met in order for an equation to be balanced? The elements in the reactants are the same as the elements
den301095 [7]

Answer:

The elements in the reactants are the same as the elements in the products

Explanation:

The condition for a balanced equation is as follows :

The number of atoms for each element in reactant = Number of atoms for each element in product.

Total charge on reactant and product must be same.

The example of a balanced equation is:

Reaction of carbon and hydrogen :

C+2H_2\rightarrow CH_4

No. of carbon atom on Carbon on LHS = 1

No. of carbon atom on Hydrogen on LHS = 4

No. of carbon atom on Carbon on RHS = 1

No. of carbon atom on Hydrogen on RHS = 4

So, for a balanced equation, The elements in the reactants are the same as the elements in the products. Hence, the correct option (a).
