The units of temperature are different. one is Fahrenheit and the other is Celsius

Both are correct. Just the unit is different. 1 F = 32 + 9/5 x C.

Answer:

salts do not conduct electricity. unless u try to dissociate its ions,it cannot.

metals are good conductors of electricity.

acids also conduct electricity if you dissociate them into ions.

Veronika [31]

To solve this problem we must use the trigonometric relations, in this case as we have the ramp and the height the concentric trigonometric property to the sin\theta will allow us to find the angle.

The sine of angle A, is defined as

Sin A = \frac{BC}{AC}

Sin \theta = \frac{35}{225}

Sin \theta = 8.9\°

Therefore the angle of elevation is 8.9°

A parallel-plate capacitor is charged and then is disconnected from the battery. By what factor does the stored energy change wh
andrew-mc [135]

Answer:

0.5

Explanation:

The energy of a charged capacitor is given by \frac{1}{2}QC where Q is the charge on it and C is its capacitance. The capacitance is defined, geometrically, as

\dfrac{\epsilon A}{d}

where \epsilon is a constant that is determined by the material between the plates, A is the area of the plates and d is the distance between them. It is then that the capacitance is linearly inversely proportional to the separation distance; as the distance increases, the capacitance reduces.

Because it is linear, when the separation distance is doubled, other factors remaining constant, the capacitance is halved. Because the capacitance is halved, the energy is halved.

Let's see the mathematics.

Initial capacitance, C_1 at initial separation, d_1

C_1=\dfrac{\epsilon A}{d_1}

If separation is doubled, separation becomes d_2=2d_1. Then the capacitance becomes

C_2=\dfrac{\epsilon A}{d_2}

C_2=\dfrac{\epsilon A}{2d_1}

C_2=0.5\dfrac{\epsilon A}{d_1}

C_2=0.5C_1

Initial energy, E_1=\frac{1}{2}QC_1

Final energy, E_2=\frac{1}{2}QC_2= \frac{1}{2}Q\times0.5C_1

E_2=0.5\times\frac{1}{2}QC_1=0.5E_1

Hence, \frac{E_2}{E_1}=0.5

Do you think ill look better in a french braid or a bun for a figure skating show.
Setler [38]
Hmmm...both seem beautiful, but if you're good at keeping them in then either on if fine, but buns make you seem elegant. While french braids make you look...I don't know...natural? But in my opinion, buns are easy to do and make people look good.
