Eiman connects eight 12Ω lamps in series. What is
the total resistance of the circuit?

The conduction velocity of the axon is 0.4 m/s.

Conductive velocity = Distance / Time

= 20 cm / 50 milliseconds

= 0.4 m/s

The conduction velocity of an axon is determined by its diameter and its degree of myelination. Myelin is a fatty sheath that surrounds axons and helps to insulate them, which speeds up the conduction of action potentials.

Unmyelinated axons have a conduction velocity of about 0.5 to 10 m/s, while myelinated axons can have a conduction velocity of up to 150 m/s.

The conduction velocity of axons is important for the nervous system to function properly. It determines how quickly signals can travel from one part of the body to another.

For example, the conduction velocity of axons in the spinal cord determines how quickly pain signals can travel from the skin to the brain.

Answer:

The weight is 7.5 N

Explanation:

Since the rod is uniform, its weight applies downwards at its middle (i.e 50 cm mark). The diagram attached to this answer shows the appropriate sketch.

Applying the principle of moment to the question, let the weight by represented by W.

Total clockwise moment = Total counterclockwise moment

\(F_{1}\) x \(d_{1}\) = \(F_{2}\) x \(d_{2}\)

5 x 0.3 = W x 0.2

1.5 = 0.2 W

W = \(\frac{1.5}{0.2}\)

   = 7.5 N

The value of the weight is 7.5 N.

Sedimentary rocks.

Explanation:

A rock cycle can be defined as a concept used to describe the continuous process that leads to a rock's creation, formation, transformation from one form to another, destruction and reformation over a specific period of time. The natural phenomenons that influences the rock cycle are weathering, plate tectonic activity, erosion, etc.

A fossil can be defined as the mineral impression or remains of living organisms such as plants and animals that are prehistoric in nature.

Basically, the three (3) main types of rocks are; igneous rock, sedimentary rock and metamorphic rock.

Sediments come from living organisms such as plants to form organic sedimentary rocks and they are usually formed at pressure and temperature that doesn't destroy the fossils contained therein. Organic sedimentary rocks includes chalk, fossiliferous, coal, diatomite, etc. Also, some examples of inorganic land-derived sedimentary rocks are conglomerate, brescia and sandstone.

Hence, an organic sedimentary rock is a type of rock that contains or comprises of fossils.

The electric flux through the square sheet is \(4.4 * 10^4 Nm^2/C\), when a uniform electric field of magnitude \(1.1 * 10^4 N/C\) is perpendicular to a square sheet with sides 2.0 m long.

The electric flux through a closed surface is given by the formula:

\(\[ \Phi = \mathbf{E} \cdot \mathbf{A} \]\)

where \(\(\Phi\)\) is the electric flux, \(\(\mathbf{E}\)\) is the electric field, and \(\(\mathbf{A}\)\) is the area vector of the surface. In this case, the electric field \(\(\mathbf{E}\)\) is perpendicular to the square sheet, and the magnitude of the electric field is given as \(1.1 * 10^4 N/C\).

The area of the square sheet is \(\(A = (2.0 \, \text{m})^2 = 4.0 \, \text{m}^2\)). Since the electric field is perpendicular to the surface, the angle between the electric field and the area vector is 0 degrees.

Substituting the values into the formula, we have:

\(\[ \Phi = (1.1 \times 10^4 \, \text{N/C}) \cdot (4.0 \, \text{m}^2) = 4.4 \times 10^4 \, \text{N} \cdot \text{m}^2/\text{C} \]\)

Large above ground mausoleums were not common in the elite Shang burials.

Explanation:

Large, above the ground mausoleums were not common so the answer is option B.

The average atomic mass of element X is approximately 128.44 amu.  The average atomic mass takes into account the relative abundances of the isotopes.

The average atomic mass is calculated by multiplying the mass of each isotope by its abundance and summing up these values. In this case, element X has three isotopes:

¹²⁶X, ¹²⁸X, and ¹³⁰X, with abundances of 22.00%, 34.00%, and 44.00% respectively.

To calculate the average atomic mass, we multiply the mass of each isotope by its abundance and sum up these values. The atomic mass of ¹²⁶X is 126 amu, ¹²⁸X is 128 amu, and ¹³⁰X is 130 amu.

Using the given abundances and atomic masses, we can calculate the average atomic mass as follows:

Average Atomic Mass = (126 amu × 0.22) + (128 amu × 0.34) + (130 amu × 0.44)

                  = 27.72 amu + 43.52 amu + 57.20 amu

Answer:

forever alone uwu......

Answer:

512.5 mJ

Explanation:

Let the two identical charges be q = +35 µC and distance between them be r₁ = 46 cm. A charge q' = +0.50 µC located mid-point between them is at r₂ = 46 cm/2 = 23 cm = 0.23 m.

The electric potential at this point due to the two charges q is thus

V = kq/r₂ + kq/r₂

= 2kq/r₂

= 2 × 9 × 10⁹ Nm²/C² × 35 × 10⁻⁶ C/0.23 m

= 630/0.23  × 10³ V

= 2739.13 × 10³ V

= 2.739 MV

When the charge q' is moved 12 cm closer to either of the two charges, its distance from each charge is now r₃ = r₂ + 12 cm = 23 cm + 12 = 35 cm = 0.35 m and r₄ = r₂ - 12 cm = 23 cm - 12 cm = 11 cm = 0.11 cm.

So, the new electric potential at this point is

V' = kq/r₃ + kq/r₄

= kq(1/r₃ + 1/r₄)

= 9 × 10⁹ Nm²/C² × 35 × 10⁻⁶ C(1/0.35 m + 1/0.11 m)

= 315 × 10³(2.857 + 9.091) V

= 315 × 10³ (11.948) V

= 3763.62 × 10³ V

= 3.764 MV

Now, the work done in moving the charge q' to the point 12 cm from either charge is

W = q'(V' - V)

= 0.5 × 10⁻⁶ C(3.764 MV - 2.739 MV)

= 0.5 × 10⁻⁶ C(1.025 × 10⁶) V

= 0.5125 J

= 512.5 mJ

Work done will be:  \(512.5 \mu J\).

Given:

q = +35 µC

q' = +0.50 µC

r₁ = 46 cm

r₂ = 46 cm/2 = 23 cm = 0.23 m

The electric potential at this point due to the two charges q is thus

\(V = \frac{kq}{r_2}+\frac{kq}{r_2}\\\\ V= \frac{2kq}{r_2}\\\\V= \frac{2 * 9 * 10^9Nm^2/C^2 * 35 * 10^{-6} C}{0.23 m}\\\\V= \frac{630}{0.23*10^3}V\\\\V= 2739.13 * 10^3 V\\\\V= 2.739 \mu V\)

When the charge q' is moved 12 cm closer to either of the two charges, its distance from each charge is now;

r₃ = r₂ + 12 cm = 23 cm + 12 = 35 cm = 0.35 m and

r₄ = r₂ - 12 cm = 23 cm - 12 cm = 11 cm = 0.11 cm.

Thus, the new electric potential at this point is

\(V' = \frac{kq}{r_3} + \frac{kq}{r_4}\\\\V= kq(\frac{1}{r_3}+\frac{1}{r_4})\\\\V= 9 * 10^9 Nm^2/C^2 * 35 * 10^{-6} C (\frac{1}{0.35m}+\frac{1}{0.11m})\\\\V= 315 * 10^3(2.857 + 9.091) V\\\\V= 315 * 10^3 (11.948) V\\\\V= 3763.62 * 10^3 V\\\\V= 3.764 \mu V\)

Now, the work done in moving the charge q' to the point 12 cm from either charge is:

\(W = q'(V' - V)\\\\W= 0.5 * 10^{-6} C(3.764 MV - 2.739 MV)\\\\W= 0.5 *10^{-6} C(1.025 * 10^6) V\\\\W= 0.5125 J\\\\W= 512.5 \mu J\)

The zeroth law of thermodynamic states that if two systems are in thermal equilibrium in equilibrium. with a third system, they are. with each other".

One of the four fundamental laws of thermodynamics is the zeroth law. It offers a stand-alone definition of temperature that excludes the second law's concept of entropy. Ralph H. Fowler created the law in the 1930s, many years after the first, second, and third laws had gained widespread acceptance.

According to the zeroth law, if two thermodynamic systems are in thermal equilibrium with one another and with a third system separately, then all three systems are in thermal equilibrium with one another.

The mathematical representation of thermodynamics depends on the zeroth law. It mathematically transforms the relationship between systems' thermal equilibrium into an equivalence relation, which can symbolize the equality of a particular quantity related to each system.

Can anyone help me with my history question.

Answer:

Explanation:

Use simplified formula:

The magnetic field generated by a current loop is given by the equation:

B = (μ0 * n * I * A) / (2 * R)

where μ0 is the permeability of free space (4π x 10^-7 T·m/A), n is the number of turns, I is the current, A is the area of the loop, and R is the distance from the center of the loop to the point where the magnetic field is measured.

In this case, we want to make a loop with a length of 1.30 m, so the circumference of the loop will be C = 2πr = 1.30 m, where r is the radius of the loop. Solving for r, we get:

r = C / (2π) = 1.30 m / (2π) = 0.2077 m

The area of the loop is given by A = πr^2, so:

A = π(0.2077 m)^2 = 0.1358 m^2

Now we can plug in the values given and solve for the number of turns:

0.700 T = (4π x 10^-7 T·m/A) * n * 1.20 A * 0.1358 m^2 / (2 * 0.2077 m)

Solving for n, we get:

n = (0.700 T * 2 * 0.2077 m) / [(4π x 10^-7 T·m/A) * 1.20 A * 0.1358 m^2]

n = 147.4 turns

Therefore, you need to make a current loop with 147 turns to generate a 0.700 mT magnetic field at the center of the loop using the entire 1.30 m long copper wire.
