Example of a matter is conductivity.

<h3>What is conductivity?</h3>

Conductivity (or explicit conductance) of an electrolyte arrangement is a proportion of its capacity to direct power. The SI unit of conductivity is Siemens per meter (S/m). Conductivity estimations are utilized regularly in numerous modern and ecological applications as a quick, cheap and solid approach to estimating the ionic substance. For instance, the estimation of item conductivity is an ordinary method for observing and persistently pattern the presentation of water cleaning frameworks. Conductivity is an estimation of the capacity of a fluid answer for move an electrical flow. The ebb and flow are conveyed by particles, and subsequently the conductivity increments with the convergence of particles present in arrangement, their portability, and temperature of the water.

An ohmic dipole of resistance 100 ohm is crossed by a current of intensity 120 ma. Calculates the voltage across this chemical d

Sedaia [141]

Answer:

12.0 Volt

Explanation:

Step 1: Given data

Resistance of the ohmic dipole (R): 100 Ohm

Intensity of current (I): 120 mA (0.120 A)

Step 2: Calculate the voltage (V) across this chemical dipole

To calculate the voltage across the ohmic dipole, we will use Ohm's law.

I = V/R

V = I × R

V = 0.120 A × 100 Ohm = 12.0 V

Q C Blaise Pascal duplicated Torricelli's barometer using a red Bordeaux wine, of density 984kg/ m³ , as the working liquid (Fig

levacccp [35]

The pressure within Earth's atmosphere is referred to as atmospheric pressure or barometric pressure. 10.701 was the height h of the wine column for normal atmospheric pressure.

<h3>What is Atmospheric pressure?</h3>

The pressure within Earth's atmosphere is referred to as atmospheric pressure or barometric pressure. The definition of the standard atmosphere is 101,325 Pa, or the same as 1013.25 millibars, 760 mm Hg, 29.9212 inches Hg, or 14.696 psi.

The force per unit area that an atmospheric column exerts is known as atmospheric pressure, often known as barometric pressure (that is, the entire body of air above the specified area). A weather indicator is atmospheric pressure. There will typically be clouds, wind, and precipitation when a low-pressure system enters a region. Fair, quiet weather is frequently a result of high pressure systems.

We have the density for the red Bordeaux wine given $\rho=965 \frac{\mathrm{kg}}{\mathrm{m}^3}$ , the atmospheric pressure on the Torricelli's barometer is given by:

$P_{a t m}=\rho g h$

Solving for the height of wine in the column we have this:

$h=\frac{P_{\text {anm }}}{\rho g}$

And replacing we have:

$h=\frac{101300 \mathrm{~Pa}}{965 \frac{\mathrm{kg}}{\mathrm{m}^3 9.81 \frac{\mathrm{m}}{\mathrm{m}^2}}}=10.701 \mathrm{~m}$$$

So the height of the red Bordeaux wine would be $\mathrm{h}=10.701 \mathrm{~m}$ . A very high value on this case if we compare with the usual values for this variable.

Beyond the petition Neptune a field of smaller bodies orbits the Sun.Some scientists think these objects are the remains of mate

Vladimir79 [104]

This is a very valid hypothesis for many reasons. One is that solar systems form from massive amounts of dust, ice, and debris that eventually form into planets and such. This means it is very possible for this 'excess material' if you will to have moved into orbit behind Neptune.

What is transferred by a force moving an object through a distance?

Komok [63]

<span>When you apply force to move an object at a distance, you are applying work. And work is energy in transit. The answer is letter D. For example, you see a cart at a distance. You observe that it is not moving. You want to transfer it to your backyard. You apply force to the cart and observed that the cart is not at the same position as it was before. You are applying work to the cart by transferring your energy to it.</span>

A velocity selector uses a fixed electric field of magnitude E and the magnetic field is varied to select particles of various e

defon

Answer: we need B/√2 for having twice the energy i.e 0.17B

Explanation:

This is actually a simple one, so i will guide you through it.

We know that Energy here means Kinetic Energy (K.E)

and the expression is given thus;

Energy = 1/2 mv2

and velocity v = E/B

let us make x the energy intially, foe electric field E, magnetic field B, mass m

so, x = 1/2 m (E/B)2

we have to find magnetic field for which twice the energy so , let magnetic field be y, so

2x = 1/2m(E/y)2

y = B/√2 = 0.17B

therefore, we need B/√2 for having twice the energy

cheers i hope this helps!!!!
