Answer:

Total energy stored in both is 0.0018J

Explanation:

Formula to calculate the total energy stored between two capacitors = 1/2CV²

Energy stored the First Capacitor = 1/2 × 25× 10⁻⁶f × (120)²

Energy stored = 0.0015J

Energy stored in the second Capacitor = 1/2 × 5× 10⁻⁶f × (120)²

Energy stored = 0.0003J

Total Energy stored = Energy stored in capacitance 1 + Energy stored in Capacitor 2

= 0.0015J+ 0.0003J

= 0.0018J

The statement that best describes the just world hypothesis is people deserve what happens to them, whether good or bad. The correct option is a.

A hypothesis is a testable declaration about the relationship among two or more variables or a suggested explanation for some observed phenomenon in a scientific context.

A hypothesis is an assumption formed based on evidence. This is the first step in any investigation that converts research questions into predictions. It consists of variables, a population, and the relationship between the variables.

A hypothesis is a statement rather than a question. The scientific question in your project is not your hypothesis. The hypothesis is a well-informed, testable prediction of what will occur.

A scientific paper should begin with a clear statement of the hypothesis. This helps the reader understand the issue. People deserve what happens to them, whether good or bad, according to the statement that best describes the just world hypothesis.

Basically, when water evaporates, it always absorbs energy. What happens is that a molecule steals surface energy for all molecules until it is hot enough to evaporate. This is how the evaporation process happens. For this reason, the surface cools because the molecules steal the heat from the medium. This can easily be noticed when we sweat and after the water molecules evaporate from our body, it cools.

The water feels cool when it evaporates because the process of evaporation requires energy, and that energy is drawn from the surrounding environment, including our skin.

When water molecules evaporate, they transition from the liquid phase to the gas phase, escaping the surface of the water. During this phase transition, water molecules gain energy from their surroundings to overcome the intermolecular forces holding them together in the liquid. This energy absorption leads to a cooling effect on the surrounding environment.

When water evaporates from our skin, it draws heat energy from our body, which makes us feel cooler.

Overall, the cooling sensation when water evaporates is a result of energy transfer, where the water molecules gain energy from their surroundings, leading to a cooling effect on the surrounding objects or our bodies.

there are three ways by which we can transfer heat from one place to other

1. Conduction

In this method of heat transfer heat can be transferred from one place to other without actual movement of medium molecules. This is possible in solid conducting mediums

2. Convection

Here heat energy is carried away along with the medium molecules where medium molecules can move from one place to other while heat is transferred. It is possible in liquid and gas but not possible in solids

3. Radiation

In this mode of heat transfer we do not require any medium and here heat transferred by electromagnetic waves

So we can feel heat from sun in form of electromagnetic waves and it is the fastest way to transfer the heat also it do not require any medium

Answer:

A nuclear to thermal and radiant

Explanation:

Nuclear fission is the disintegration of the force that holds the nucleus of the atom together, creating two different but lighter nuclei.

In nuclear fission, it seeks to break the force of attraction or nuclear force that joins the protons and neutrons that form the nucleus of an atom. Neutrons without electric charge are used against the nucleus of the atom to produce enough excitation energy to deform the nucleus into two halves.

The nuclei obtained from nuclear fission are different and lighter than the initial nucleus. The excess energy that emerges from nuclear fission is what is known as nuclear energy.

Nuclear fission produces energy in the form of heat and other radiations releasing (ie thermal and radiation in general), in turn, other neutrons. Each generated neutron collides with the other nuclei created, producing a chain reaction.

Nuclear fission can be used for power generation through a nuclear reactor. A nuclear reactor is a facility that generates self-sustained and controlled nuclear reactions, and uses the energy released from the fission of atoms.

For example, one of the first applications of nuclear fissions used uranium atoms to produce electricity.

The gravitational potential energy of a 65.7 kg person standing on the roof of a 135 meter building is 86,752.17 Joules, calculated using the formula PEg = mgh.

The gravitational potential energy (PEg) of a person or object is calculated using the formula PEg = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m/s² on Earth), and h is the height above a reference point in meters.

In the case of a 65.7 kg person standing on the roof of a 135 meter building, the gravitational potential energy can be calculated as follows:

PEg = mgh = (65.7 kg) (9.8 m/s²) (135 m) = 86,752.17 Joules

Hence, the person has a gravitational potential energy of 86,752.17 J when standing on the roof of the building.

So, there are 3.34 C of charge are needed to spark.

Answer:

The correct answer is 3.

Explanation:

The curved path of a projectile, known as its trajectory, is primarily due to the influence of gravity, along with other factors such as air resistance and the rotation of the Earth.

Gravity: The dominant force acting on a projectile is gravity, which pulls the object downward toward the center of the Earth. As a projectile moves forward, gravity pulls it down, causing it to follow a curved path rather than a straight line. The motion creates a parabolic trajectory when air resistance is negligible.

Initial Velocity and Launch Angle: When a projectile is launched, it has an initial velocity and is given a specific angle with respect to the horizontal. These factors contribute to how high and how far the projectile will travel.

Air Resistance: In real-world scenarios, air resistance also plays a significant role in shaping the projectile's path. This force opposes the motion of the projectile and causes deviations from the ideal parabolic path. The effect of air resistance can be complex and often results in a more flattened trajectory.

The buoy will be moved by the force exerted on it by the waves.

Explanation

As the buoy is anchored to the ocean floor, the buoy will be floating in the ocean floor.

When the large wave approaches, it will act as an external unbalanced force on the buoy.

The waves will consist of crest and trough.

The crest region have higher force. So the crest will first interact with the buoy and the external force of crest will make the buoy to float upward along with the motion of crest.

Then the trough region will lessen the force and thus it will again come back in its original position.
