Answer:

Explanation:

Gases have three characteristic properties: (1) they are easy to compress, (2) they expand to fill their containers, and (3) they occupy far more space than the liquids or solids from which they form. An internal combustion engine provides a good example of the ease with which gases can be compressed.

A typical current in a lightning bolt is 103 a. estimate the magnetic field 9 m from the bolt (in t). (enter the magnitude.)

kifflom [539]

The magnetic field is

$2.288 \times 10 {}^{ - 6} T$

what is magnetic field?

Magnetic field is defined as the relationship between the permittivity of free space,the magnitude of electric current,and distance.

Here is the formula,

$B = \frac{µ0l }{2π R}$

here,

B= magnitude of the magnetic field

l= magnitude of electric current

R=distance

µ0=permittivity of free space

Now,using above formula we can calculate the magnetic field

$B = \frac{µ0l }{2π R}$

$\frac{4\pi \times 10 {}^{ - 7}. \frac{m}{a} \times 103 }{2\pi \times (9m)}$

$= 2.288 \times 10 {}^{ - 6} T$

Thus,the magnetic field is

$= 2.288 \times 10 {}^{ - 6} T$

4. For a series of experimentally measured values give the definition of (a) average or mean value (b) the deviation from the me

Naya [18.7K]

Answer:

a) x_average = ∑ $x_{i}$ / n , b) Δx_{i} = x_{i} –x_average,

d) σ = √(1/n-1 ∑ Dx_{i}² )

Explanation:

Some definitions are requested

a) the average value is the sum of all the values divided by the number of them, if the uncertainties are random, this is the closest value to the real one

x_average = ∑ $x_{i}$ / n

b) The deviation from the mean value or absolute error is the measured value minus the average value

Δx_{i} = x_{i} –x_average

c) is the average value of the deviations

Δx_average = ∑ Δx_{i} / n

d) It is a measure of the dispersion of the values with respect to their average value, it takes the worst of all cases, widely used for large numbers of data

σ = √(1/n-1 ∑ Dx_{i}² )

Experimental results should be given as follows

Average value ± uncertainty and the standard deviation

(x_average + - Δx_average)

Calculate the Energy (E) in joules for that wavelength and record it in the table below. Remember that E = HF, where h the Planc

Viefleur [7K]

In that formula for Energy, 'F' is the frequency of the photon.
But <u>Frequency = (speed)/(wavelength)</u>, so we can write the
Energy formula as
   E = h c / (wavelength) .

So the energy, in joules, of a photon with that wavelength, is . . .

   E = (6.6 x 10⁻³⁴) x (3 x10⁸) / (that wavelength)

      = <em>(1.989 x 10⁻²⁵) / (that wavelength, in meters) .</em>

Bumek [7]

No, the density of diamond and graphite would not be the same

Explanation:

What is density?

Density is the amount of substance per unit volume. It is simply mass divided by volume.

Density is greatly influenced by the way substances are packed.

Substances that are well packed will have lower volume for the same amount of matter than another that is poorly packed.

The carbon atoms in graphite are poorly packed. They are arranged layers upon layers.
Diamond carbon atoms have a cross-linked networked pattern. They are well packed.
For the same mass of matter, graphite will take up more space than diamond.

Since:

Density = $\frac{mass}{volume}$

The one that has a lesser volume will have a higher density.

Therefore diamond will have a higher density.
