The unit represents a value that is one order of magnitude larger than a decimeter is a meter

<h3>Further explanation </h3>

Magnitude is something that can be measured or counted

The principal amount is the amount that has been determined based on the agreement of the scientists

Derivative magnitude is a quantity derived from the principal amount

There are 7 main quantities that have been determined based on international standards, namely:

  • 1. Length, meters (m)
  • 2. Time, second (s)
  • 3. Mass, kilograms (kg)
  • 4. Temperature, kelvin (K)
  • 5. Light intensity, candela (cd)
  • 6. Electric current, amperage (A)
  • 7. Amount of substance, mol (m)

The length of the principal is to indicate the distance between two points in a place

The symbol is usually expressed in l, length

Length measurements can be used by several measuring instruments such as ruler, caliper length, meter, screw micrometer

The main length unit consists of 7 units other than other units of length such as inches, miles, yards, feet:

  • Kilometers, km
  • Hectometer, hm
  • Dekameter, dam
  • Meters, m
  • Decimeter, dm
  • centimeters, cm
  • millimeters, mm

Each one unit descends then multiplied by 10, and if one unit increases then divided by 10

Conversion of other mass units:

mm millimeters = 10⁻³ m

km kilometers = 10³ m

µm micrometers (mcm) = 10µm

nm nanometers = 10⁻⁹ m

Gm gigameters = 10⁹ m

ρm picometers = 10⁻¹² m

An order of magnitude used base ten number.

If numbers differ by one order of magnitude, so the number is about 10 times different in quantity . If values differ by two orders of magnitude, they differ about 100.

The decimeter unit is located between the centimeter and meter.

Decimeter value = 10⁻¹m, centimeter = 10⁻² m, so that the unit represents a value that is one order of magnitude larger than a decimeter is meter

<u>The unit that represents the value of one order higher than the decimetre is </u><u>meter. </u>

<u> </u>

Further Explanation:  

The units are the ways of representation of the physical quantities and the amount of magnitude contained by the particular physical quantity.

For example: the length is a measure of the distance between the two points. The standard quantity to measure the length is metre. There are several other magnitudes that can measure the smaller and larger order of magnitudes.

The different magnitudes that are used to measure lengths of different order are:

• Kilometre \left( {{{10}^3}\,{\text{m}}} \right)

• Hectometre \left( {{{10}^2}\,{\text{m}}} \right)  

• Decametre \left( {{{10}^1}\,{\text{m}}} \right)

• Metre \left( {1\,{\text{m}}} \right)

• Decimetre \left( {{{10}^{ - 1}}\,{\text{m}}} \right)

• Centimetre  \left( {{{10}^{ - 2}}\,{\text{m}}} \right)

• Millimetre \left( {{{10}^{ - 3}}\,{\text{m}}} \right)  

<u>Thus, the quantity that has the magnitude of one order larger than the decimetre is </u><u>metre. </u>

Two point charges are separated by 10 cm, with an attractive force between them of 15 N. Find the force between them when they a
suter [353]

Answer:

(a) the force is 8.876 N

(b) the magnitude of each charge is 4.085 μC

Explanation:

Part (a)

Given;

coulomb's constant, K = 8.99 x 10⁹ N.m²/C²

distance between two charges, r = 10 cm = 0.1 m

force between the two charges, F = 15 N

when the distance between the charges changes to 13 cm (0.13 m)

force between the two charges, F = ?

Apply Coulomb's law;

F = \frac{Kq_1q_2}{r^2} \\\\let \ Kq_1q_2 = C\\\\F =\frac{C}{r^2} \\\\C = Fr^2\\\\F_1r_1^2 = F_2r_2^2\\\\F_2 =\frac{F_1r_1^2}{r_2^2} \\\\F_2 = \frac{15*0.1^2}{0.13^2} \\\\F_2 = 8.876 \ N

Part (b)

the magnitude of each charge, if they have equal magnitude

F = \frac{KQ^2}{r^2}

where;

F is the force between the charges

K is Coulomb's constant

Q is the charge

r is the distance between the charges

F = \frac{KQ^2}{r^2} \\\\Q = \sqrt{\frac{Fr^2}{K} } \\\\Q =  \sqrt{\frac{15*(0.1)^2}{8.99*10^9} } = 4.085 *10^{-6} \ C\\\\Q = 4.085 \ \mu C

You hang a heavy ball with a mass of 10 kg from a gold wire 2.6 m long that is 1.6 mm in diameter. You measure the stretch of th
PolarNik [594]

<u>Answer:</u> The Young's modulus for the wire is 6.378\times 10^{10}N/m^2

<u>Explanation:</u>

Young's Modulus is defined as the ratio of stress acting on a substance to the amount of strain produced.

The equation representing Young's Modulus is:

Y=\frac{F/A}{\Delta l/l}=\frac{Fl}{A\Delta l}

where,

Y = Young's Modulus

F = force exerted by the weight  = m\times g

m = mass of the ball = 10 kg

g = acceleration due to gravity = 9.81m/s^2

l = length of wire  = 2.6 m

A = area of cross section  = \pi r^2

r = radius of the wire = \frac{d}{2}=\frac{1.6mm}{2}=0.8mm=8\times 10^{-4}m      (Conversion factor:  1 m = 1000 mm)

\Delta l = change in length  = 1.99 mm = 1.99\times 10^{-3}m

Putting values in above equation, we get:

Y=\frac{10\times 9.81\times 2.6}{(3.14\times (8\times 10^{-4})^2)\times 1.99\times 10^{-3}}\\\\Y=6.378\times 10^{10}N/m^2

Hence, the Young's modulus for the wire is 6.378\times 10^{10}N/m^2

Compute the expected shell-model quadrupole moment of 209Bi () and compare with the experimental value, - 0.37 b
Over [174]

Answer:

0.22 b

Explanation:

Quadrupole moment of the nucleon is,

Q=-\frac{2j-1}{2(j+1)}\frac{3}{5}R^{2}

And also,

R^{2}=R^{2} _{0}A^{\frac{2}{3} }

And, R _{0}=1.2\times 10^{-15}m

Now,

Q=-\frac{2j-1}{2(j+1)}\frac{3}{5}R^{2} _{0}A^{\frac{2}{3} }

For Bismuth j=\frac{9}{2} and A is 209.

Q=-\frac{2\frac{9}{2} -1}{2(\frac{9}{2} +1)}\frac{3}{5}(1.2\times 10^{-15}) ^{2}(209)^{\frac{2}{3} }\\Q=0.628\times 35.28\times 10^{-30} \\Q=22.15\times 10^{-30} m^{2} \\Q=0.2215\times 10^{-28} m^{2} \\Q=0.22 barn

Therefore, the expected value of quadrupole is 0.22 b which is quite related with experimental value which is 0.37 b
