Answer:

Potential energy is the stored energy of position possessed by an object.

Potential energy is described as stored energy. Depending on the relative positions of various system components, stored energy. When a spring is squeezed or extended, its potential energy increases.

Potential energy is the power that an item may store due to its position in relation to other things, internal tensions, electric charge, or other circumstances.

A boulder perched precariously atop a cliff. The rock will be moving if it falls, converting the potential energy to kinetic energy. a longbow's stretched-elastic string.

Potential energy is the energy that is stored in any item or system as a result of its location or component arrangement. The environment outside the object or system, such as air or height, has no impact on it. Conversely, kinetic energy is the force that propels the particles of an item or a system into motion.

Since light has no mass and is an example of electromagnetic radiation, it possesses neither kinetic nor potential energy. The remaining forms exhibit both kinetic and potential energy characteristics.

1) The greater magnitude of force, the faster the acceleration.

2) Acceleration is caused by unbalanced forces.

    This is not exactly a answer you can use but this is some information that you can use to find out the answer.

    You can usually confirm the charge associate degree particle unremarkably has by the element's position on the periodic table: The alkali metals (the IA elements) lose one negatron to create a ion with a 1+ charge. The alkaline-earth metal metals (IIA elements) lose 2 electrons to create a 2+ ion.

    Nonmetals type negative ions (anions). A range 7|chemical element|element|gas} atom should gain 3 electrons to possess an equivalent number of electrons as AN atom of the subsequent gas, neon. Thus, a gas atom can type AN ion with 3 additional electrons than protons and a charge of 3−.

The atoms of platinum and silver are identical. This statement is false.

Platinum is a chemical element which is represented by the symbol Pt. Its atomic number is 78. It is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal.

The elements silver and platinum have the same properties in terms of ductility, malleability, and conductivity of heat and electricity.Platinum is more ductile than gold, silver or copper.

Both metals silver and platinum appear silver. They have gray undertones, unlike white gold which has a warmer, yellow undertone, instead platinum is much brighter and shinier and silver is a duller, gray appearance.

Thus, The atoms of platinum and silver are identical. This statement is false.

The final pressure in the heated can is 2.51 atm

From the question given above, the following data were obtained:

Initial temperature (T₁) = 25 °C = 25 + 273 = 298 K

Initial pressure (P₁) = 1 atm

Final temperature (T₂) = 475 °C = 475 + 273 = 748 K

The final pressure can be obtained as illustrated below:

[tex] \frac{P_1}{T_1} = \frac{P_2}{T_2} \\ \\ \frac{1}{298} = \frac{P_2}{748} \\ \\ cross \: multiply \\ \\ 298 \times P_2 = 1 \times 748 \\ \\ divide \: both \: side \: by \: 298 \\ \\ P_2 = \frac{748}{298} \\ \\ P_2 = 2.51 \: atm[/tex]

Explanation:

Any substance that inhibits the growth and replication of a bacterium or kills it outright can be called an antibiotic. Antibiotics are a type of antimicrobial designed to target bacterial infections within (or on) the body. This makes antibiotics subtly different from the other main kinds of antimicrobials widely used today:

Antiseptics are used to sterilise surfaces of living tissue when the risk of infection is high, such as during surgery.

Disinfectants are non-selective antimicrobials, killing a wide range of micro-organisms including bacteria. They are used on non-living surfaces, for example in hospitals.

Of course, bacteria are not the only microbes that can be harmful to us. Fungi and viruses can also be a danger to humans, and they are targeted by antifungals and antivirals, respectively. Only substances that target bacteria are called antibiotics, while the name antimicrobial is an umbrella term for anything that inhibits or kills microbial cells including antibiotics, antifungals, antivirals and chemicals such as antiseptics.

Most antibiotics used today are produced in laboratories, but they are often based on compounds scientists have found in nature. Some microbes, for example, produce substances specifically to kill other nearby bacteria in order to gain an advantage when competing for food, water or other limited resources. However, some microbes only produce antibiotics in the laboratory

Answer:

Antibiotics commonly are produced by soil microorganisms and probably represent a means by which organisms in a complex environment, such as soil, control the growth of competing microorganisms. Microorganisms that produce antibiotics useful in preventing or treating disease include the bacteria and the fungi.

An endothermic process may be spontaneous if: C. the product particles have more freedom of motion than the reactant particles.

An endothermic reaction can be defined as a type of chemical reaction in which heat energy is absorbed from the environment.

Generally, heat energy is absorbed in a chemical reaction when the energy of the products is greater (more) than the energy of the reactants and this is referred to as an endothermic reaction.

Similarly, an endothermic process may be spontaneous when the product particles have more freedom of motion than the reactant particles.

Answer:   A transfer of electrons occurs when fluorine and calcium react to form an ionic compound. This is because calcium is in group two and so forms ions with a two positive charge. ... A pairs of shared electrons makes one covalent bond. The compound formed is known as a molecule***

An ionic bond is formed through the transfer of one or more valence electrons, typically from a metal to a non-metal, which produces a cation and an anion that are bound together by an attractive electrostatic force.

The momentum of the bowling ball will be greater than the rest balls.

The correct answer to the question is Option C. The 5 kg bowling ball

Momentum is defined as the product of mass and velocity i.e

Momentum = mass × velocity

If we keep the velocity of the object constant, the momentum will depend on the mass of the object.

Thus, the higher the mass, the greater the momentum and the lesser the mass, the smaller the momentum.

From the question given above,

Mass of tennis = 0.5 Kg

Mass of basketball = 2 Kg

Mass of bowling ball = 5 kg

We can see that the bowling ball has a higher mass.

Therefore, the momentum of the bowling ball will be greater than the rest balls.
