Answer:

it is a measure of the heat content of fuels or energy sources

Explanation:

Answer:

Please refer the the definition of an electric current below

Explanation:

Electric current is the flow of electric charge in a circuit. It is defined as the rate at which electric charge flows through a given area of a conductor. The flow of electric charge is caused by the motion of electrons, which are negatively charged particles that exist in most materials.

Electric current is generated by applying a potential difference, or voltage, across a conductor. The voltage causes a difference in electric potential energy between the ends of the conductor, and this difference drives the flow of electrons through the conductor. The electrons move from the negative terminal of the voltage source towards the positive terminal, and as they move, they transfer energy to the conductor in the form of heat or light.

The amount of current that flows through the conductor is determined by the voltage applied and the resistance of the conductor. Resistance is a property of the conductor that resists the flow of current, and it is measured in ohms. According to Ohm's law, the current in a circuit is directly proportional to the voltage and inversely proportional to the resistance.

This relationship can be expressed as

\(\sf I=\dfrac{V}{R}\)

\(\sf I\) is the current in amperes

\(\sf V\) is the voltage in volts

\(\sf R\) is the resistance in ohms

The resulting equation of motion for the system is given by m × x''(t) + k × x(t) = f(t), which is 2 × x''(t) + 18 * x(t) = 2 * sin(2t).

What is  equation of motion?

The equations of motion are a set of mathematical relationships that describe the motion of objects under the influence of forces. There are different sets of equations of motion, depending on the specific scenario and the type of motion being considered (linear motion, projectile motion, circular motion, etc.). The equations of motion for linear motion, also known as the equations of uniformly accelerated motion.

To find the equation of motion for the system, we start with Newton's second law of motion, which states that the sum of forces acting on an object is equal to the mass of the object multiplied by its acceleration. In this case, the object is the 2-kg mass attached to the spring.

The force exerted by the spring is proportional to the displacement of the mass from its equilibrium position, and it can be expressed as F_spring = -k× x(t), where k is the spring constant and x(t) is the displacement of the mass at time t.

In addition to the force exerted by the spring, there is an external force f(t) = 2 ×sin(2t) acting on the mass.

Applying Newton's second law, we have the equation of motion: m ×x''(t) + k ×x(t) = f(t).

Substituting the given values, m = 2 kg and k = 18 N/m, we obtain 2 ×x''(t) + 18 × x(t) = 2 ×sin(2t).

Therefore, the resulting equation of motion for the system is 2 × x''(t) + 18 × x(t) = 2 × sin(2t).

Billy Joe's acceleration will be 5 m/s².

To determine Billy Joe's acceleration, we can use Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

The formula for Newton's second law is:

F = m * a

Where:

F is the net force acting on the object,

m is the mass of the object, and

a is the acceleration.

In this case, the net force acting on Billy Joe is the force exerted by Billy Bob, which is 300 Newtons. The mass of Billy Joe is 60 kg.

Plugging these values into the formula, we can solve for the acceleration:

300 N = 60 kg * a

Divide both sides of the equation by 60 kg:

300 N / 60 kg = a

Simplifying the equation gives:

The acceleration of the car would be 0.00019 m/s².

To find the acceleration of a car, we can use the following equation:

acceleration = (final velocity - initial velocity) / time

Since the car speeds up from 40 mph to 70 mph, the final velocity is 70 mph, the initial velocity is 40 mph, and the time taken is 6 s.

Convert the velocities to meters per second to get consistent units:

Initial velocity = 40 mph = 40 × 0.447 = 17.88 m/s

Final velocity = 70 mph = 70 × 0.447 = 31.29 m/s

Acceleration = (final velocity - initial velocity) / time

Acceleration = (31.29 - 17.88) / 6

Acceleration = 13.41 / 6

Acceleration = 2.23 m/s²

Therefore, the average acceleration of the car is 2.23 m/s².

To convert to mph², multiply by the conversion factor (0.000038) to get:

acceleration = 2.23 × 0.000038acceleration = 0.00008474 mph²

Alternatively, if the acceleration is required in terms of mph², we can use the following formula:

acceleration = (final velocity - initial velocity) / time

where the velocities are in mph, and time is in seconds.

Using this formula, we get:

acceleration = (70 - 40) / 6acceleration = 30 / 6

acceleration = 5 mph²

Since 1 mph² = 0.000038 m/s², we can convert this to m/s²:

acceleration = 5 × 0.000038acceleration = 0.00019 m/s²

Therefore, the acceleration of the car would be 0.00019 m/s².

The SI unit of charge is the coulomb (C). It is related to the fundamental unit of charge, which is the charge of an electron or proton. The magnitude of the charge of an electron is equal to -1.602 x 10^-19 C, while the magnitude of the charge of a proton is equal to +1.602 x 10^-19 C.

This means that an electron has a negative charge and a proton has a positive charge. The charge of an object is determined by the number of electrons and protons it has. If an object has an equal number of electrons and protons, it is said to be neutral and has a charge of zero.

The charge of an object can be measured using an instrument called an electrometer. Conductors, such as metals, have a high degree of conductivity and can easily transfer charge. In contrast, insulators have a low degree of conductivity and do not easily transfer charge.

The SI unit of conductance is the siemens (S), which is the reciprocal of resistance (ohms). The conductance of a material is determined by its ability to allow the flow of electric current. The concentration of charged particles in a material can affect its conductivity. For example, increasing the concentration of ions in an electrolyte solution can increase its conductivity.

By using relative density method, the density of the object and the oil are 6.3 and 0.92 respectively

Density can simply be defined as the mass per unit volume of the material. While relative density is the ratio of the weight of the substance to the weight of equal volume of water.

Given that an object weighs 315 N in air. When immersed in water, it weighs 265 N. When it is immersed in oil, it weighs 269 N.

a. To calculate the density of the object, Let us first calculate the upthrust  of water on the object

upthrust  of water on the object = loss in weight in water

upthrust  of water on the object = 315 - 265

upthrust  of water on the object = 50 N

The density of the object = weight in air / upthrust  of water on the object

The density of the object = 315/50

The density of the object = 6.3

B. To calculate the density of the oil, let us first find the upthrust in oil and water

Upthrust in oil = 315 - 269

Upthrust in oil = 46 N

Upthrust in water = 315 - 265

Upthrust in water = 50

The density of the oil =  Upthrust in oil  / Upthrust in water

The density of the oil = 46 / 50

The density of the oil = 0.92

Therefore, the density of the object is 6.3 while the density of the oil is 0.92

Explanation:

The force between the planet and the satellite can be calculated using the following equation

Where G = 6.67 x 10^(-11) N m²/kg², m1 is the mass of the satellite, m2 is the mass of the Earth and d is the distance from the center of the Earth to the satellite

Since the radius of the Earth is 6,371 km, we get

d = 42 km + 6,371 km = 6413 km

Then, to convert to m, we need to multiply by 1000

d = 6413 km x 1000 m/km = 6.413 x 10^6 m

Finally, replacing m1 = 900 kg, m2 = 5.972 x 10^24 kg, and d = 6.413 x 10^6 m, we get:

Therefore, the force between the planet and the satellite is 8716.97 N

The volume of the jet fuel with a mass of 97.5 kg and a density of 0.804 g/cm³ is approximately 121.28 liters.

To calculate the volume of the jet fuel, we can use the formula for density:

density (ρ) = mass (m) / volume (v)

Rearranging the formula to solve for volume, we have:

volume (v) = mass (m) / density (ρ)

The mass of the jet fuel is 97.5 kg and the density is 0.804 g/cm³, we need to convert the density to the appropriate units. Since the given mass is in kilograms, we'll convert the density to kg/cm³ as well.

0.804 g/cm³ = 0.804 × 10³ kg/m³ = 804 kg/m³

Now we can substitute the values into the formula:

volume (v) = 97.5 kg / 804 kg/m³

Simplifying the equation:

volume (v) = 0.12128 m³
