Given :

Capacity of capacitor is, \(C = 10\ \mu F\).

To Find :

At what voltage can a 10 μF capacitor be energized to 0.45 J.

Solution :

We know, energy in capacitor is given by :

\(E = \dfrac{CV^2}{2}\)

So,

\(V = \sqrt{\dfrac{2E}{C}}\\\\V = \sqrt{\dfrac{2\times 0.45}{10}}\ \mu V\\\\V = 0.3 \ \mu V\)

Therefore, voltage required is \(0.3 \ \mu V\) .

If charge q is stored on a capacitor, one plate of the capacitor holds a positive charge Q, while the other holds a negative charge -Q.

While charging a capacitor charges move in such a way that , firstly a single electron gets added to one side of the capacitor and then the electron has a electric field that repels other electrons .

This field reaches through space and pushes the electron in the other plate  because of which that plate acquired an induced positive charge . This is how same amount of charge get acquired on both the plates  .

Hence , one plate of the capacitor holds a positive charge Q, while the other holds a negative charge -Q.

Answer:

M1u1+ m2u2= (m1+m2) V by uisng this equation we can find out the velocity. The answer would be 42 ms-1. IS IT CORRECT?

Answer:

208 Joules

Explanation:

The radius of the circular path the charge moves, r = 26 m

The magnetic force acting on the charge particle, F = 16 N

Centripetal force, \(F_c\) = m·v²/r

Kinetic energy, K.E. = (1/2)·m·v²

Where;

m = The mass of the charged particle

v = The velocity of the charged particle

r = The radius of the path of the charged particle

Whereby the magnetic force acting on the charge particle = The centripetal force, we have;

F = \(F_c\) = m·v²/r = 16 N

(1/2) × r × \(F_c\) = (1/2) × r × m·v²/r = (1/2)·m·v² = K.E.

∴ (1/2) × r × \(F_c\) = (1/2) × 26 m × 16 N =  = (1/2)·m·v² = K.E.

∴ 208 Joules = K.E.

The kinetic energy of an particle moving in the circular path, K.E. = 208 Joules.

If you were in a car crash and weren't wearing your seat belt, you would not keep moving at the speed of the crash.

In a car crash, the principle of inertia states that an object in motion will remain in motion unless acted upon by an external force. If a person is not wearing a seat belt during a crash, they will continue moving at the speed they were traveling in the car before the crash.

However, as soon as the car comes to a

sudden stop due to the impact, the person's body will continue moving forward at the same speed until it collides with another object in the car or is stopped by external forces, such as the windshield, dashboard, or other parts of the vehicle.

This can result in severe injuries or ejection from the vehicle. Wearing a seat belt is crucial as it restrains the body, preventing it from continuing to move forward at the same speed as the crash and reducing the risk of injury. Seat belts are designed to distribute the force of impact over a larger area, slowing down the body's movement and providing protection during a collision.

Mechanical energy is indeed select one because the roller coaster selects one energy due to friction and air resistance as it travels down the track

When a ball is thrown onto the ground, it typically begins to roll with a certain velocity. However, due to Newton's first law, the ball would theoretically keep rolling without any force acting against it. In reality, the ball eventually stops after a certain distance, which implies that a force is being applied to it; this force is known as friction. Friction provides the necessary grip to allow us to walk without slipping and can be beneficial in many cases. On the other hand, friction can also be a major hindrance to motion, and around 20% of the power from a car engine is used to overcome friction in its moving parts.

The best description of Jodi's error is "The electrons move from areas of low to high electric potential." because the electrons actually move from areas of high to low electric potential. thus option 2 is the answer.

Jodi's error is in statement 2, which says that electrons move from areas of low to high electric potential. In reality, electrons move from areas of high to low electric potential. This is because electric potential represents the energy per unit charge, and electrons are negatively charged particles that naturally move from higher energy levels to lower ones. The direction of electron flow determines the direction of electric current, which is the flow of electric charge. The other statements on Jodi's list are generally correct, including the fact that voltage (or potential difference) is what drives current flow, and that current is measured in amperes.

However, it's important to note that the movement of electrons in a current is not always continuous, as they can be impeded by resistance, which causes them to lose energy and generate heat.

Answer:

mass 3 has the least slope therefore the mass is the greatest.

Force is the product of mass and acceleration. Here the acceleration is constant for all bodies and force is different. The greater the force, greater will be mass. Thus, mass 1 is the largest.

Force is an external agent acting on a body to deform it or to change its state from motion or rest. There are different kinds of forces such as magnetic force, nuclear force, gravitational force etc.

According to Newton's second law of motion, the force acting on a body is the product of its mass and acceleration. Thus, greater the mass of the body, greater force is required to accelerate the body.

In the given figure the acceleration is increasing for all bodies, the mass which is associated with greater force is the largest. Here the greater force is associated with mass 1. Hence, mass 1 is the largest.

The core of a highly evolved high mass star, depending on the type of stellar remnant, can be as small as the size of the Earth (for a white dwarf) or as compact as about 10 kilometers (for a neutron star).

The core of a highly evolved high mass star is typically a compact object known as a stellar remnant. There are two main types of stellar remnants that can form depending on the mass of the star: white dwarfs and neutron stars.

A white dwarf is the remnant of a star with a mass up to about 8 times that of the Sun. Its core is about the size of the Earth, which is much smaller compared to the original size of the star.

On the other hand, a neutron star is formed when a star with a mass greater than about 8 times that of the Sun undergoes a supernova explosion. The core of a neutron star is incredibly dense and compact, with a radius typically on the order of 10 kilometers (6.2 miles). Neutron stars are composed primarily of tightly packed neutrons and are extremely massive.

In summary, the core of a highly evolved high mass star, depending on the type of stellar remnant, can be as small as the size of the Earth (for a white dwarf) or as compact as about 10 kilometers (for a neutron star).

A newborn infant and a doctor are pulled apart by much less gravitational force than the distance between Earth and Mars.

The gravitational force between Earth and Mars can be calculated using the formula F = G(m1m2)/r^2, where G is the universal gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between their centers. The mass of Earth is about 5.97 x 10^24 kg, the mass of Mars is about 6.39 x 10^23 kg, and the average distance between them is about 225 million km. Using these values and the formula, we can calculate that the gravitational force between Earth and Mars is about 2.7 x 10^22 N.

On the other hand, the gravitational force between a newborn baby and a doctor can be calculated using their masses and the distance between them. Assuming an average newborn baby mass of 3.5 kg and an average doctor mass of 75 kg, and a distance of 1 meter between them, we can calculate that the gravitational force between them is about 2.2 x 10^-8 N.

Clearly, the gravitational force between Earth and Mars is much greater than the force between a newborn baby and a doctor. The greater forces are between the larger and more massive objects, such as planets or stars, due to their greater masses and distances.

Answer:

Resistencia = 12.5 Ohmios

Explanation:

Dados los siguientes parámetros;

Voltaje = 3.5 Volts

Corriente = 0.28 Amps

Para encontrar el resistencia;

La ley de Ohm establece que a temperatura constante, la corriente que fluye en un circuito eléctrico es directamente proporcional al voltaje aplicado en los dos puntos e inversamente proporcional a la resistencia en el circuito eléctrico.

Matemáticamente, La ley de Ohm viene dada por la fórmula;

Voltaje = corriente * resistencia

Resistencia = voltaje/corriente

Resistencia = 3.5/0.28

Resistencia = 12.5 Ohmios

Por tanto, la resistencia del filamento de una linterna de bolsillo es de 12,5 ohmios.
