In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. As such, it generalizes a circle, which is the special type of ellipse in which the two focal points are the same.

Classification makes it easier for scientists to study certain groups of organisms.

The standard reduction potential for the half-reaction of Be^2+ + 2e^- -> Be is given as E^0 = 3.83 V.

For the half-cell Hg^2+ | Hg, the standard reduction potential is not provided in the given information. To calculate the electric potential for the voltaic cell, we need the reduction potential for the Hg^2+ | Hg half-cell.

A voltaic cell, also known as a galvanic cell or an electrochemical cell, is an electrochemical device that generates electrical energy through a spontaneous chemical reaction. It consists of two half-cells connected by an external circuit and a salt bridge or porous barrier that allows the flow of ions between the two half-cells.

Each half-cell consists of an electrode immersed in an electrolyte solution. The electrode is typically made of a metal or a conductive material, and the electrolyte is a solution containing ions that can participate in the redox (reduction-oxidation) reaction.

Answer:

39

Explanation:

Relative mass does not need to be calculated as it is listed on the periodic table. Potassium's relative atomic mass is around 39.

To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

Answer: I'm sure it is c

Explanation: that's my answer

The statements that relate the mass and the speed of the object to its kinetic energy are when the mass of an object doubles, its kinetic doubles and when an object's speed doubles, its kinetic energy more than doubles.

Kinetic energy is the energy that is used to do some work. The kinetic energy is directly proportional to the mass of the object, and it is proportional to the square of the speed of the object.

Thus, the correct options are b and c.

Answer: For transverse waves, the waves move in perpendicular direction to the source of vibration.

For longitudinal waves, the waves move in parallel direction to the source of vibration .

They are similar within the sense that energy is transferred within the kind of waves.

Explanation:

The shared characteristics between traverse, longitudinal and surface waves include :

Mechanical waves are simply waves which requires a material medium to propagate. They include longitudinal, surface and traverse waves.

Also, all three waves transfer energy through a medium without the transfer of materials or matter in the medium.

Therefore, all three waves are mechanical waves and do not transfer matter.

Answer:

"Yes," a moving skateboard has energy.

When the skater seems to be in motion or throughout a movement, the potential energy converts itself into the kinetic form of energy, and then it becomes potential energy again.

Furthermore, somewhere after every movement, the same skateboarder was around a similar height, — in other words thus every time it is equally powerful.

Answer:An exothermic reaction may be defined as a type of reaction in which energy is significantly liberated in the form of heat or light. In such types of reactions, energy is generally transferred into the surroundings rather than utilized from the surroundings.

The option "energy from an outside source is continuously being added" represents an endothermic reaction in which heat or light energy is externally been provided. The option "more heat is given off than is put into the reaction" is not absolutely true because exothermic reactions liberate energy but it does not matter if it is higher or lower than that of being put into the reaction.

Therefore, the reactants have more heat energy than the products is a statement that is true about exothermic reactions. Thus, the correct option for this question is C.

Explanation:

you welcome

Energy from outside sources is continuously being added, since its an exothermic reaction it always focusses on releasing large amount of energy upon activation and combustion.

It cuts off on giving energy back to its surrounding unlike endothermic reaction where the generated energy is given back to the environment to restore its energy levels.

Therefore, it makes it clear that exothermic reaction is a type of reaction that uses combustion to gather the energy lying around in the surrounding to generate large amount of energy and heat and keeps on producing heat until and unless there is energy in surrounding.

D. There are more than 100 naturally occurring elements that make up all matter.

Explanation:

All matter is made up of elements, which are substances that cannot be broken down into simpler substances by chemical means. There are more than 100 naturally occurring elements, each with its own unique properties and characteristics. These elements combine to form compounds, which are substances made up of two or more elements that are chemically combined in a specific ratio. For example, water is a compound made up of two hydrogen atoms and one oxygen atom. Atoms can bond with each other in various ways to form compounds, but they do not always bond to achieve a stable neutron-proton ratio. The stability of an atom or compound depends on a variety of factors, including the arrangement of its electrons and the nature of the chemical bonds it forms with other atoms.
