when an rl circuit is connected to a battery, what happens to the potential difference across the resistor and the emf across the inductor?

The acceleration of the object is approximately 2.38 m/s². To find the acceleration of the object, we can use the formula:

acceleration = change in velocity / time

The object goes from rest to a speed of 10 m/s in 4.2 seconds, the change in velocity is:

change in velocity = final velocity - initial velocity

change in velocity = 10 m/s - 0 m/s

change in velocity = 10 m/s

Plugging the values into the formula, we have:

acceleration = change in velocity / time

acceleration = 10 m/s / 4.2 s

acceleration ≈ 2.38 m/s²

Therefore, the acceleration of the object is approximately 2.38 m/s².

A measurement of a substance's density in relation to water's density is its specific gravity, which is more officially known as relative density. In general, specific gravity is calculated for solids and liquids in respect to water in its densest condition (at a temperature of 4 Celsius or 39.2 Fahrenheit), and for gases in proportion to air at room temperature. It is not stated with units because it is a ratio. SG or Sp. Gr. are abbreviations for specific gravity.

Temperature and air pressure affect how dense an object is. For precise measurements of specific gravity, it is necessary for scientific reasons to regulate and display the temperature and pressure.

An equilateral triangle is a triangle whose sides are all equal in length and has three equal angles of 60° each. To draw an equilateral triangle with sides of length 5, you can use a compass and a ruler to measure 5 cm. Using the compass, place the needle at one end of the line segment and draw an arc that intersects the line segment at another point.

Place the needle on the intersection point and draw another arc that intersects the first arc at a third point. The line segments connecting the three points are all of equal length 5 and form an equilateral triangle.To draw an altitude in an equilateral triangle, we need to drop a perpendicular line from one of the vertices to the opposite side. This line is known as the altitude.

When the altitude is drawn, it creates two smaller right-angled triangles with the base of the equilateral triangle. We can use this to find the length of the altitude.To find the length of the altitude of the equilateral triangle with sides of length 5, we need to use the Pythagorean theorem since we know that the smaller right-angled triangles have a base of 2.5 (half the side length) and a hypotenuse of 5 (side length). Using a² + b² = c², where a and b are the legs of the right triangle and c is the hypotenuse, we get:a² + (2.5)² = (5)²a² + 6.25 = 25a² = 18.75a ≈ 4.33.

Therefore, the length of the altitude is approximately 4.33 units.To compute the trigonometric ratios of this triangle, we can use the sides and altitude of the equilateral triangle. Using SOHCAHTOA (sine, cosine, tangent, cosecant, secant, and cotangent), we can find the ratios for the angles of the triangle.Sin(60°) = Opposite/Hypotenuse = 4.33/5 = 0.866Cos(60°) = Adjacent/Hypotenuse = 2.5/5 = 0.5Tan(60°) = Opposite/Adjacent = 4.33/2.5 = 1.732Cosecant(60°) = Hypotenuse/Opposite = 5/4.33 = 1.154Secant(60°) = Hypotenuse/Adjacent = 5/2.5 = 2Cotangent(60°) = Adjacent/Opposite = 2.5/4.33 = 0.577

The solution to the equation ln(x) = x - 31, correct to six decimal places, is x ≈ 24.662174.

Newton's method, also known as Newton-Raphson method, is an iterative numerical method used to find the roots of a real-valued function. It is a powerful algorithm for finding solutions to equations where it may be difficult or impossible to obtain an analytical solution.

To find the solutions of the equation ln(x) = x - 31 using Newton's method, we start by rearranging the equation to f(x) = ln(x) - x + 31 = 0.

Next, we need to choose an initial guess for the solution, let's say x0 = 20.

Then, we can use the Newton's method iterative formula:

xn+1 = xn - f(xn)/f'(xn)

where f'(x) is the derivative of f(x).

For our equation, f'(x) = 1/x - 1.

Let's perform the iterations:

x1 = x0 - (ln(x0) - x0 + 31) / (1/x0 - 1)

x1 = 20 - (ln(20) - 20 + 31) / (1/20 - 1)

x1 ≈ 24.660633

x2 = x1 - (ln(x1) - x1 + 31) / (1/x1 - 1)

x2 ≈ 24.662174

x3 ≈ 24.662174

Performing additional iterations, we find that the value of x converges to approximately 24.662174.

Therefore, the solution to the equation ln(x) = x - 31, correct to six decimal places, is x ≈ 24.662174.

The  answer is that the statement is true only if the two forces are acting in the same direction. If the two forces are acting in opposite directions, then they cannot be combined into a single resultant force.

When two forces act on a body in the same direction, they can be combined into a single resultant force by simply adding their magnitudes. This is because the direction of the resultant force will be the same as the direction of the two forces.

However, when two forces act on a body in opposite directions, they cannot be simply added together. Instead, they will cancel each other out and create a net force of zero. In this case, the two forces cannot be combined into a single resultant force.

The activity of the sample after 5 hours is 2.5 * 10^9 dps or 2.5 * 10^9 Bq

The activity of a radioactive sample refers to the rate at which its nuclei decay, and it is typically measured in units of disintegrations per second (dps) or becquerels (Bq).

To determine the activity of the sample after 5 hours, we need to consider the concept of half-life. The half-life of a radioactive substance is the time it takes for half of the nuclei in a sample to decay.

Given that the half-life of the nuclei in the sample is 2.5 hours, we can calculate the number of half-lives that occur within the 5-hour period.

Number of half-lives = (Time elapsed) / (Half-life)

Number of half-lives = 5 hours / 2.5 hours = 2

This means that within the 5-hour period, two half-lives have occurred.

Since each half-life reduces the number of nuclei by half, after one half-life, the number of nuclei remaining is (1/2) * (10^10) = 5 * 10^9 nuclei.

After two half-lives, the number of nuclei remaining is (1/2) * (5 * 10^9) = 2.5 * 10^9 nuclei.

The activity of the sample is directly proportional to the number of remaining nuclei.

Therefore, After 5 hours, the sample has an activity of 2.5 * 109 dps or 2.5 * 109 Bq.

Answer: 1 degree

Explanation:  I looked it up.

The resistance of a circuit that contains two 50.0 Ω resistors connected in series with a 12.0 V battery is 100 Ω. The resistance of the circuit is equal to the sum of the individual resistors when they are connected in series.

In this case, two 50.0 Ω resistors are connected in series, resulting in a total resistance of 100 Ω. Resistance can be defined as the obstruction that electricity faces when it travels through a conductor. The greater the resistance, the less current is allowed to flow through the circuit. The following equation is used to calculate resistance: R = V / IWhere R is resistance, V is voltage, and I is current.

Resistance can also be calculated using Ohm's Law if we know the values of voltage and current. When resistors are connected in series, the total resistance of the circuit is equal to the sum of the individual resistors. This is expressed by the following equation:RT = R1 + R2 + ... + RNWhere RT is the total resistance of the circuit, and R1, R2, and RN are the individual resistors. In this case, the circuit contains two 50.0 Ω resistors connected in series.
