By conservation of momentum, we will see that the initial velocity of the torpedo is 15.4 m/s

The conservation of momentum says that the total momentum before the collision must be the same as after the collision.

Before the collision we have a momentum:

P₀ = torpedo momentum + target momentum.

Where the momentum is given by:

Momentum = Mass×Velocity.

Then the initial momentum is:

P₀ = (1450kg)*V + (670 kg)*0m/s

Where V is the initial velocity of the torpedo.

For the final momentum, the torpedo and the target travel together with a velocity of 10.6 m/s, so we can see that the final momentum is:

P₁ = (1450kg + 670kg)*10.6m/s

Because of the conservation, we must have:

P₀ = P₁

(1450kg)*V = (1450kg + 670kg)*10.6m/s

(1459kg)*V = 22,472 kg*m/s

V = (22,472 kg*m/s)/(1459kg) = 15.4 m/s

So the initial velocity of the torpedo was 15.4 m/s

Explicación:

Se dice que el trabajo se realiza cuando una fuerza aplicada a un objeto hace que el objeto se mueva a través de una distancia. El trabajo realizado por un cuerpo se expresa mediante la fórmula;

Workdone = Fuerza * Distancia

Como Fuerza = masa * aceleración,

Workdone = masa * aceleración * distancia

Masa dada = 5.0kg, aceleración = 2.0m / s² d =?

Para obtener d, usaremos una de las leyes del movimiento,

d = ut + 1 / 2at²

u = 0 (ya que el cuerpo acelera desde el reposo) yt = 7.0s

d = 0 + 1/2 (2) (7) ²

d = 49m

Workdone = 5 * 2 * 49

Workdone = 490 Julios

Three capacitors with capacitance values of 8.0 μf, 11 μf, and 16 μf are connected in parallel. The equivalent capacitance is calculated by adding up the individual capacitances, resulting in a total of 35 μf.

When capacitors are connected in parallel, the equivalent capacitance is equal to the sum of individual capacitances. Therefore, to find the equivalent capacitance of the given capacitors, we simply add their capacitance values.

C_eq = C_1 + C_2 + C_3

C_eq = 8.0 μF + 11 μF + 16 μF

C_eq = 35 μF

The equivalent capacitance of the three capacitors connected in parallel is 35 μF.

In parallel connection, the positive plate of all capacitors is connected together and the negative plate of all capacitors is also connected together. When capacitors are connected in parallel, the voltage across each capacitor is the same and equal to the voltage across the entire circuit. The total capacitance of the circuit is increased, which results in an increase in the amount of charge that can be stored in the circuit.

In practical applications, capacitors are often connected in parallel to increase the capacitance of a circuit. For example, in an audio system, capacitors are used to filter out unwanted noise from the signal. By connecting multiple capacitors in parallel, the amount of noise that can be filtered out is increased, resulting in a cleaner audio signal.

Answer:

1. The weight of the column of water above

2. Due to Gravity

(I would say there are two answers for this question)

Explanation:

1.

The pressure in a liquid is due to the weight of the column of water above. Since the particles in a liquid are tightly packed, this pressure acts in all directions. For example, the pressure acting on a dam at the bottom of a reservoir is greater than the pressure acting near the top.

2.

Fluid pressure can be caused by gravity, acceleration, or forces in a closed container. Since a fluid has no definite shape, its pressure applies in all directions. Fluid pressure can also be amplified through hydraulic mechanisms and changes with the velocity of the fluid.

Mass is an extensive physical property because it is dependent on the amount or quantity of matter present in a system.

Mass is a measure of the total amount of matter that is present in an object or substance, and it is directly proportional to the number of atoms or molecules that make up that object or substance.

Intensive properties, on the other hand, do not depend on the amount of matter present in a system. Examples of intensive properties include temperature, density, and specific heat. These properties remain constant regardless of the size or quantity of the sample.

In contrast, if you combine two objects, the total mass will be equal to the sum of the individual masses of the objects. This is what makes mass an extensive property. The more mass there is in a system, the more extensive the property becomes.

Therefore, mass is an essential parameter for describing many physical phenomena, such as momentum, energy, and force. It is an essential factor in the laws of physics, and it plays a crucial role in determining the behavior of objects in motion.

London dispersion forces are weak intermolecular forces and are considered van der Waals forces. Temporary dipoles can occur in non-polar molecules when the electrons that constantly orbit the nucleus occupy a similar location by chance.

the 55Ω resistor dissipates approximately 10.97μJ of energy as the capacitor discharges completely.

To find the energy dissipated by the 55Ω resistor, we first need to calculate the total resistance of the circuit, which is 55Ω + 150Ω = 205Ω.
Using the formula for the time constant of an RC circuit, we can find the time it takes for the capacitor to discharge completely:  τ = RC = 0.75μF * 205Ω = 153.75μs
After one time constant, the voltage across the capacitor will have decreased to approximately 36.8% of its initial value (80 V). So, the voltage across the 55Ω resistor at this point will be:
V = 80 V * 0.368 = 29.44 V

Using Ohm's Law, we can find the current flowing through the 55Ω resistor:
I = V / R = 29.44 V / 55Ω = 0.535 A

Finally, we can use the formula for energy dissipated by a resistor:  E = I^2 * R * t
where t is the time it takes for the capacitor to fully discharge, which is approximately 5 time constants (since it takes about 5 time constants for the voltage across the capacitor to decrease to less than 1% of its initial value). So:
t = 5 * τ = 768.75μs
Plugging in the values, we get:  E = (0.535 A)^2 * 55Ω * 768.75μs = 10.97μJ

Hi! I'm happy to help you with your question. When a magnet is rapidly plunged into a coil and then equally rapidly extracted, the voltages induced in each case can be described as follows:

1. Rapidly plunging the magnet into the coil:

As the magnet moves towards the coil, the magnetic field passing through the coil changes.

This change in the magnetic field induces an electromotive force (EMF) in the coil, according to Faraday's law of electromagnetic induction.

The induced EMF creates a voltage across the coil, with a specific polarity based on the direction of the magnetic field and the direction of movement of the magnet.

2. Equally rapidly extracting the magnet from the coil:

As the magnet moves away from the coil, the magnetic field passing through the coil changes again.

This change in the magnetic field also induces an EMF in the coil, according to Faraday's law of electromagnetic induction.

The induced EMF creates a voltage across the coil, but with the opposite polarity compared to the previous case, as the direction of the magnetic field change is reversed.

In both cases, the voltages induced in the coil are due to the changing magnetic field created by the movement of the magnet.

The faster the magnet is plunged into or extracted from the coil, the greater the induced voltage will be.

The "weight" of an object can be determined by multiplying its mass by the acceleration due to gravity of the Earth. The acceleration due to gravity on Earth is around 9.81 m/s².

Therefore, the weight of the space lander on Earth would be:Weight = Mass x Acceleration due to gravity= 600 kg x 9.81 m/s²= 5886 N (newtons)What is the "weight" of this space vehicle on Venus itself?The weight of the space lander on Venus can be determined using Newton's Law of Gravitation. Newton's Law of Gravitation states that every point mass in the universe attracts every other point mass with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. F = G x (m₁m₂/d²)where F is the force of gravity G is the gravitational constant (6.67 x 10^-11 Nm²/kg²)m₁ is the mass of the first objectm₂ is the mass of the second objectd is the distance between the centers of the two objects Using the given values;Mass of space lander, m₁ = 600 kg

Mass of Venus, m₂ = 4.867 x 10²⁴ kg Diameter of Venus = 12,100 km or 1.21 x 10^7 meters (distance between the centers of the two objects)G = 6.67 x 10^-11 Nm²/kg²

F = ((m₁m₂)/d²) x G= (600 x 4.867 x 10²⁴)/(1.21 x 10^7)² x 6.67 x 10^-11

= 2364.19 N

When the output does not meet the equilibrium quantity in a market, a situation known as disequilibrium occurs. Disequilibrium refers to a state where there is an imbalance between the quantity demanded and the quantity supplied of a particular good or service. In this situation, two possibilities can arise: Excess Demand and Excess Supply.

Excess Demand: If the quantity demanded exceeds the quantity supplied, it creates a situation of excess demand or a shortage. Consumers are willing to purchase more of the product at the prevailing price than what is available in the market. This can lead to increased competition among consumers, rising prices, and a potential loss of potential sales for suppliers.

Excess Supply: On the other hand, if the quantity supplied exceeds the quantity demanded, it creates a situation of excess supply or surplus. Suppliers are producing more of the product than what consumers are willing to purchase at the prevailing price. This can lead to price reductions, decreased profitability for suppliers, and a buildup of unsold inventory.

In either case, the market is not in equilibrium, and there is a discrepancy between the quantity demanded and the quantity supplied. In response to disequilibrium, market forces such as price adjustments, changes in consumer behavior, or shifts in production levels may occur in an attempt to restore equilibrium.
