Complete question is;

A 50.-ohm resistor, an unknown resistor R, a 120-volt source, and an ammeter are connected in a complete circuit. The ammeter reads 0.50 ampere.

A) Calculate the equivalent resistance of the circuit shown.

B) Determine the resistance of resistor R shown in the diagram.

Answer:

A) R_eq = 240 Ω

B) R = 190 Ω

Explanation:

A) To get the equivalent resistance, we will use the formula;

R = V/I

Where;

V is Voltage

I is current

R is equivalent resistance

From the question, V = 120 V and I = 0.5A

Thus;

R_eq = 120/0.5

R_eq = 240 Ω

B) From the image, we see that the resistors are connected in series.

Formula for resistors in series is;

R = R1 + R2 +..... Rn

Thus;

240 = 50 + R

R = 240 - 50

R = 190 Ω

A) The equivalent resistance of the circuit shown will be  240 Ω.

B) The resistance of resistor R will be 190 Ω

Resistance is a type of opposition force due to which the flow of current is reduced in the material or wire. Resistance is the enemy of the flow of current.

The given data in the problem is;

R is the resistance = 50.-ohm

v is the voltage = 120-volt source

I is the value of the current =0.50 ampere.

A) The equivalent resistance of the circuit shown will be  240 Ω.

According to ohm's law

\(\rm R= \frac{V}{I} \\\\ \rm R= \frac{120}{0.5} \\\\ \rm R=240 \ ohm\)

Hence the equivalent resistance of the circuit shown will be 240 Ω.

B) The resistance of resistor R will be 190 Ω

The given resistors are connected in the series;

R = R1 + R2 +..... Rn

240 = 50 + R

R = 240 - 50

R = 190 Ω

Hence the resistance of resistor R will be 190 Ω

One of the four mentioned is not a plate boundary is b. insurgent.

Plate tectonics is the theory that explains the movement of Earth's lithosphere, which is composed of large plates that glide over the mantle. The plates are separated by three types of plate boundaries: divergent, convergent, and transform. Transform boundary is where two plates slide past one another in opposite directions, either horizontally or diagonally. The San Andreas Fault is a well-known example of a transform boundary. Divergent boundaries are where two plates pull away from each other and new crust is created.

The Mid-Atlantic Ridge is an example of a divergent boundary and convergent boundary is where two plates move towards each other and one plate gets consumed or goes under the other. The Himalayas were created as a result of the collision of two convergent plates, the term insurgent is not used in plate tectonics. The correct term that describes the three main types of plate boundaries is not insurgent but instead transform, divergent, and convergent boundaries. So the correct answer is b. insurgent.

The total amount of liquid will still be 100 milliliters.

Milliliters (mL) is a unit of volume measurement that is equal to the volume of a cube that is 1 cm on each side. It is commonly used to measure liquids, such as milk, juice, or medicine. Milliliters can also be used to measure dry ingredients, such as flour or sugar. One milliliter is equal to 0.001 liters, or about 0.034 fluid ounces.

For 100 milliliters of juice, you would need 100 milliliters of fruit juice. In other words, the amount of fruit juice required to make 100 milliliters of juice is the same as the amount of juice you are starting with. This is because when you mix fruit juice with water, the total amount of liquid remains the same. So if you start with 100 milliliters of juice and then add 100 milliliters of water, the total amount of liquid will still be 100 milliliters.

To determine the number of half-lives that have elapsed, we need to compare the ratio of 14C to 14N atoms found in the hip bone fragment.

The ratio of 1 14C atom for every 31 14N atoms suggests that the hip bone fragment contains a smaller amount of 14C compared to the expected ratio found in a living organism. Since 14C undergoes radioactive decay with a half-life of approximately 5730 years, we can calculate the number of half-lives that have elapsed by observing how many times the ratio needs to double to reach the expected ratio.

In this case, if the expected ratio is 1:1, then the observed ratio of 1:31 would require five doublings to reach 1:1. Therefore, approximately five half-lives have elapsed since the death of the organism from which the hip bone fragment originated.

Explanation:

The given number is 1.30x10-5. We need to convert it into scientific notation. We know that, any no can be written in this form as follows :

\(N=m. 0\times 10^n\) ...(1)

m is any real no and n is any integer

If we compare the given no with equation (1), then, we found that m = 1.3 and n = -5.

It means that the given no is already in scientific notation. It can be written as :

\(N=1.30\times 10^{-5}\)

The scientific notation for 1.30 × 10⁻⁵ is  1.30E-5.

Scientific notation is a way to represent numbers that are either very large or very small using powers of 10. It consists of two components: the coefficient and the exponent.

In the given number, 1.30 × 10⁻⁵, the coefficient is 1.30, and the exponent is -5. The coefficient represents the significant digits of the number, and the exponent indicates the power of 10 by which the coefficient should be multiplied.

To convert the number to scientific notation, you start by moving the decimal point to the left until there is only one non-zero digit to the left of the decimal point. In this case, the decimal point is moved 5 places to the left, resulting in the coefficient 0.000013.

The exponent, -5, tells us that the decimal point has been moved 5 places to the left. In scientific notation, a negative exponent indicates a small number, as in this case.

Putting it all together, the scientific notation for 1.30 × 10⁻⁵ is 1.30E-5, where the "E" represents "times ten to the power of." It means that the number is 1.30 multiplied by 10 raised to the power of -5, which is equivalent to 0.000013 in standard decimal notation.

Therefore, 1.30E-5 is the correct scientific notation.

Explanation:

A.) what is the net upward force acting on the rocket ?

The statement "A spring loaded piston cylinder device is initially filled with 0.13 lbm" is false

. The mass of a substance is measured in kilograms (kg), not pounds (lbm). Therefore, the statement should be "A spring loaded piston cylinder device is initially filled with 0.13 kg." The pound-mass (lbm) is a unit of mass in the imperial system of measurement. The kilogram (kg) is a unit of mass in the International System of Units (SI). The SI is the most widely used system of measurement in the world. The mass of an object is the amount of matter it contains. The weight of an object is the force of gravity acting on it. The weight of an object changes depending on the strength of the gravitational field. The mass of an object does not change. In the statement "A spring loaded piston cylinder device is initially filled with 0.13 lbm," the mass of the substance is being described. The substance is being measured in pounds-mass, which is not a unit of mass in the SI system. Therefore, the statement is false. The correct statement would be "A spring loaded piston cylinder device is initially filled with 0.13 kg." This statement is true because the mass of the substance is being measured in kilograms, which is a unit of mass in the SI system.

The best description of the origin of the energy held within fossil fuels is (b) The energy within fossil fuels comes from ancient autotrophs that decomposed long ago and went through geologic processes over millions of years.

Fossil fuels such as coal, oil, and natural gas are formed from the remains of ancient organisms. These organisms, known as autotrophs, were primarily plants and microscopic algae that lived millions of years ago. Through the process of photosynthesis, these autotrophs converted sunlight, carbon dioxide, and water into organic matter, storing energy from the sun in their tissues.

Over time, as these ancient autotrophs died and were buried under layers of sediment, they underwent decomposition and were subjected to intense heat and pressure. These geologic processes, occurring over millions of years, transformed the organic matter into fossil fuels.

Dinosaurs, on the other hand, were reptiles that lived during the Mesozoic Era, which was much more recent compared to the formation of fossil fuels. The misconception that fossil fuels come from dinosaurs is incorrect.

Therefore, option B- the energy held within fossil fuels primarily originates from ancient autotrophs that decomposed and underwent geologic processes over millions of years.

Answer:

Explanation:

To estimate the Coulomb charging energy for a metallic sphere embedded in silicon, we can use the formula for the electrostatic energy of a charged capacitor. The charging energy, also known as the electrostatic energy or the electrostatic potential energy, is given by:
E = (1/2) * Q^2 / C
Where:
E is the charging energy,
Q is the charge on the metallic sphere, and
C is the capacitance of the system.

For a metallic sphere embedded in silicon, the capacitance can be approximated by the parallel plate capacitor formula:
C = ε0 * A / d
Where:
C is the capacitance,
ε0 is the vacuum permittivity (8.854 x 10^-12 F/m),
A is the surface area of the metallic sphere (4πr^2, where r is the radius), and d is the distance between the metallic sphere and the surrounding medium (in this case, silicon).
To estimate the charging energy, we need to know the charge on the metallic sphere. Without that information, we cannot provide a specific value for the Coulomb charging energy. The charging energy depends on the magnitude of the charge, which can vary depending on the system and the charging process.
If you have the charge value for the metallic sphere, please provide it so that we can calculate the charging energy.
