Option C is Correct. The object advances steadily for 4 seconds while losing position. The object then advances at a constant speed for 6 seconds. When the slope is constant, the speed is also constant.

The rate of change in velocity is greater for the graph with the sharpest slope. That thing is moving with the most velocity. Compare the traditional slope-intercept equation taught in introductory algebra with the velocity-time equation for constant acceleration.

Complete Resolution. The right response is Mass. Physical quantities with only magnitude and no direction are referred to as scalar quantities. The mass lacks direction and only has magnitude. A direction and a magnitude together make up the definition of vector quantities. Vectors include force, velocity, acceleration, and momentum.

The statement "molecules move in random directions when heated in a heat engine, and because of the lack of uniformity in the direction of molecular movement" is true.

When a heat engine is heated, molecules absorb heat energy and their kinetic energy increases. The kinetic energy of molecules causes them to move around. However, this movement is not uniform, and the molecules move in random directions.

A heat engine is a device that converts thermal energy into mechanical energy. Heat engines operate on the principle of thermodynamics.

They work by taking in thermal energy from a high-temperature reservoir, converting some of it into mechanical energy, and then releasing the remaining thermal energy to a low-temperature reservoir.The internal combustion engine in a car, the steam engine in an old locomotive, and the turbine in a power plant are all examples of heat engines. They all convert heat energy into mechanical energy to perform work.

Answer: 25%

Explanation: To find the mass percentage of a chemical you need to do mass/total mass x 100 = %.

In this case you would do 5.0/20.00 because 5.0 is the mass of the hydrogen and 20.00 is the total mass. That equals .25 so the next step is to times that by 100.

.25 x 100 = 25, so we know that the percent of the hydrogen mass in compound 1 = 25%

In double replacement reactions, two metals not combine with each other when products are formed because, metals form negative ions and like charges attract. Therefore, option A is correct.

A metal is a substance that exhibits a shiny appearance when freshly processed, polished, or shattered, and conducts electricity and heat rather well. Generally speaking, metals are malleable and ductile.

We use the (s) symbol for solid because salt is an insoluble substance that will not dissolve in water. The silver, fluoride, potassium, and chloride ions would have effectively moved to a new location if there had been no precipitate formation, but they would still be floating around as ions. In this instance, nothing happens.

When two ionic compounds exchange ions and create two new ionic compounds, this is known as a double replacement reaction.

Thus, option A is correct.

Answer:

Changes to the amount of energy through thermal transfer is most appropriate to show changes in the to temperatures of the substances as there is an increase in the thermal energy in the closed system. The increase in molecular energy through the heating process is what happens when the energy is transferred from one compound to another.

A battery is a device that converts chemical energy into electrical energy through a process known as an electrochemical reaction.

When a battery is connected to a circuit, the electrochemical reaction causes a flow of electrons from the anode to the cathode, generating an electric current that can power a device.

The metal chosen for the anode must be capable of losing electrons easily, while the metal chosen for the cathode must be capable of accepting electrons. The choice of metals can also affect the voltage and capacity of the battery, as well as its overall efficiency.

In general, the metals used in a battery should have a large difference in their electronegativity values, which determines how easily an atom can attract electrons. Common metals used in batteries include zinc, lithium, nickel, and cadmium.

158 kg = 158,000 g of phosphorus

Step 2 - Now we need to know the molar mass of phosphorus. Look for it at the periodic table. It is 30.97 g/mol.

Step 3 - We transform grams into moles:

30.97 g ---- 1 mol

158,000 g ---- x mol

x = 5,101.7 moles of phosphorus

Step 4 - We transform moles into atoms using Avogrado's constant:

6.022 x 10^23 ---- 1 mol

x ---- 5,101.7 moles of phosphorus

x = 3.072 x 10^27 atoms
