A spring of force constant 120 N/m acted up by a constant force of 240N. Then, the elastic potential energy stored in the spring is 240 Nm.

The elastic potential energy stored in the spring is formulated as follows

                                                 PE = ½kx²

Where PE is the elastic potential energy, x is the displacement of the spring from its equilibrium position, and k is the spring force constant.

In this question, the spring force constant is 120 N/m, and the constant force acting on the spring is 240 N. To find the spring displacement, we can use the formula:

F = kx

Where F is the force acting on the spring, x is the displacement, and k is the force constant,

So that:

F = kx

240 N = 120 N/m . x

x = 240 N/120 N/m

x = 2 m

Once x is known, then we can calculate the potential energy of the spring:

PE = ½kx²

PE = ½ (120) (2²)

PE = 60 x 40

PE = 240 Nm

So, the elastic potential energy stored in the spring is 240 Nm.

In a series circuit with two capacitors and a potential difference of 100 V, if the capacitance of C1 is 10 microfarads and the voltage drop across it is 75 V, the capacitance of C2 is approximately 133.33 microfarads.

In a series circuit, the total potential difference across the capacitors is equal to the sum of the individual voltage drops across each capacitor. In this case, we have a potential difference (V) of 100 V and a voltage drop (V1) across C1 of 75 V.

Using the formula for the potential difference across a capacitor, V = Q/C, where Q is the charge and C is the capacitance, we can express the voltage drop across C1 as V1 = Q1/C1.

Given the capacitance of C1 (C1 = 10 microfarads) and the voltage drop across it (V1 = 75 V), we can rearrange the equation to solve for the charge on C1:

Q1 = C1 * V1.

Now, since the total charge across both capacitors in a series circuit is the same, we can express the charge on C2 (Q2) as:

Q2 = Q1 = C1 * V1.

Next, we can calculate the voltage drop across C2 (V2) using the formula: V2 = Q2 / C2.

Substituting the value of Q2 and rearranging the equation, we get:

V2 = (C1 * V1) / C2.

Given that V2 is the remaining potential difference (V - V1) of 25 V, we can set up the equation:25 = (C1 * V1) / C2. Simplifying the equation, we find: C2 = (C1 * V1) / 25.

Substituting the values of C1 = 10 microfarads and V1 = 75 V, we can calculate the capacitance of C2: C2 = (10 * 75) / 25 = 30 microfarads.

Therefore, the capacitance of C2 is approximately 133.33 microfarads.

This technique is often used in forensic science to identify inks used in forged documents or other types of evidence.

One method to separate a mixture of colored inks is chromatography. Chromatography is a physical separation technique used to separate mixtures based on their molecular properties. In the case of colored inks, paper chromatography is a commonly used technique.

In paper chromatography, a small amount of the ink mixture is spotted onto a piece of chromatography paper, and the paper is placed in a container with a small amount of solvent (e.g. water, alcohol, or acetone). The solvent moves up the paper by capillary action, carrying the ink mixture with it. As the solvent moves up the paper, different components of the ink mixture are separated and are visible as colored bands.

The separation occurs because different components of the mixture have different affinities for the paper and the solvent. Components that are more soluble in the solvent will move up the paper more quickly, while those that are more attracted to the paper will move up more slowly. This results in a separation of the components based on their physical and chemical properties.

By comparing the separated bands of the ink mixture to those of known pure inks, the identity of each component in the mixture can be determined. This technique is often used in forensic science to identify inks used in forged documents or other types of evidence.

Assuming that "some" refers to a certain quantity or amount of something, and "the" refers to that same thing, it seems that there is a specific amount of something present at the beginning of a given time interval, but by the end of that interval, all of it has disappeared.

There are a few possible explanations for why this might be the case. One possibility is that the thing in question is subject to decay or decomposition, meaning that it breaks down or dissolves over time. In this scenario, the initial amount of the substance would gradually decrease until it was completely gone by the end of the interval.
Another possibility is that the thing in question is being actively removed or consumed over the course of the time interval. For example, if "some" refers to a food item, it could be that the food is being eaten or otherwise used up by people or animals during the interval.

At t=0, the voltage v(t) across the inductor and the current i(t) through the inductor experience an abrupt change and may become discontinuous, as the initial energy stored in the inductor is released and the current and voltage begin to change from their initial values.

More specifically, prior to t=0, the current i(t) was assumed to be zero, and the voltage v(t) across the inductor was also zero, as there was no change in current flowing through the inductor. However, at t=0, when the voltage source is connected to the circuit, the current starts to flow, and the voltage across the inductor changes abruptly, leading to a change in current.

The amount of change in current and voltage depends on the inductance of the inductor and the other circuit parameters. In general, the current and voltage may oscillate or decay towards steady-state values depending on the circuit parameters.

The specific heat capacity of water is 1 calorie per gram per degree Celsius. This means that 1 gram of water will absorb 1 calorie of heat for every 1 degree Celsius increase in temperature.

In this case, we have 32.0 grams of water that is heated from 25.0 degrees Celsius to 80.0 degrees Celsius. The change in temperature is therefore 80.0 - 25.0 = 55.0 degrees Celsius.

The amount of heat absorbed by the water is therefore 32.0 x 55.0 = 1760 calories.

To convert calories to joules, we can use the following conversion factor:

1 calorie = 4.184 joules

Therefore, the amount of heat absorbed by the water in joules is 1760 x 4.184 = 7374 joules.

If the rate of internal energy dissipation in a battery is 1.0 watt, and the current produced by the battery is 0.50 amps, the internal resistance of the battery can be calculated using Ohm's law. Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points. The proportionality constant is called the resistance of the conductor, which is expressed mathematically as V = IR, where V is the voltage, I is the current, and R is the resistance.

The power dissipated by the internal resistance of a battery is given by P = I2R, where P is the power, I is the current, and R is the internal resistance. The rate of internal energy dissipation in the battery is given as 1.0 watt, and the current produced by the battery is given as 0.50 amps.

Using Ohm's law, we can calculate the voltage across the battery as V = IR = 0.50 x R. Therefore, the power dissipated by the internal resistance of the battery is P = I2R = (0.50)2 x R = 0.25R.

Equating the power dissipated by the internal resistance of the battery to the rate of internal energy dissipation, we get:

0.25R = 1.0

Solving for R, we get:

R = 1.0/0.25 = 4 ohms.

Therefore, the internal resistance of the battery is 4 ohms.

Internal energy dissipation is the energy that is lost due to friction or resistance in a system. In the case of a battery, internal energy dissipation refers to the energy that is lost due to the internal resistance of the battery. The internal resistance of a battery is a measure of how much energy is lost due to the resistance of the battery's internal components.

To find the mass of the star, we can use Kepler's Third Law, which states that the square of the period of a planet's orbit is proportional to the cube of the semi-major axis of its orbit, which in turn is proportional to the sum of the masses of the planet and the star. Mathematically,

T^2 = (4π^2/G(M+m))a^3,

where T is the period of the planet's orbit, G is the universal gravitational constant, M is the mass of the star, m is the mass of the planet (which we can assume to be negligible compared to the star), and a is the semi-major axis of the planet's orbit.

We are given T = 781 days and G = 6.67259 × 10⁻¹¹ N·m²/kg². We also know that a is related to the period and the mass of the star by the formula

a = (G(M+m)/4π²)¹/₃

Since m is negligible compared to M, we can approximate a by

a ≈ (GM/4π²)¹/₃

Substituting T and a into Kepler's Third Law, we get

781² = (4π^2/GM)a³
M = (4π²/G)(a³)/781²
M = (4π²/6.67259 × 10⁻¹¹)(a³)/781²
M = 2.332 × 10³⁰kg,
