Answer:

I think 32.00

Explanation:

Because the equation is mass times velocity so is you mutiply 32 by 25 and 28 times 25 sample A would be greater.

The sample with the greatest average kinetic energy is sample A

The average kinetic energy of a sample can be estimated by the formula one-half of the mass sample multiplied by the speed (RMS) squared.

Mathematically, we have:

[tex]\mathbf{K.E_{avg} = \dfrac{1}{2}mv_{rms}^2}[/tex]

Provided that the speed (RMS) is constant, the average kinetic energy of sample A will be greater than the average kinetic energy of sample B because sample A has a greater mass than sample B.

the formula ,

From the given chemical equations,the one with molar ratio with smallest difference between elemental sodium (Na) as a reactant and the chemical formed as a product is equation 'a'.

Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.

A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .

The first chemical equation was put forth by Jean Beguin in 1615.By making use of chemical equations the direction of reaction ,state of reactants and products can be stated. In the chemical equations even the temperature to be maintained and catalyst can be mentioned.

Ruler. A steel ruler aids the measurement and layout of straight lines. The ruler, also called "straightedge" or "straight-edged ruler," is a long, thin strip of wood, metal or plastic marked with increments of measurement.

Measuring Tape. The modern measuring tape's roughly palm-sized casing contains a coiled strip of metal marked with increments of measurement. The metal strip, called "tape," attaches to a spring which automatically retracts the tape into the casing following use.

Walking Tape Measure. The walking tape measure, also called "surveyor's measure," records the distance traveled by a wheel. An operator pushes the measure's wheel, similar to a bicycle wheel, by a handle as an attached ticker box displays feet or meters in the same format as a car's odometer.

Laser Measure. The laser measure offers point and shoot distance measurement. In its most basic form, a laser measure is a hand-held electronic device with a digital display.

The acceleration of the mass sliding along the horizontal surface is 5.2 m/s².

Answer:

Falling objects form an interesting class of motion problems. For example, we can estimate the depth of a vertical mine shaft by dropping a rock into it and listening for the rock to hit the bottom. By applying the kinematics developed so far to falling objects, we can examine some interesting situations and learn much about gravity in the process.

The most remarkable and unexpected fact about falling objects is that, if air resistance and friction are negligible, then in a given location all objects fall toward the center of Earth with the same constant acceleration, independent of their mass. This experimentally determined fact is unexpected because we are so accustomed to the effects of air resistance and friction that we expect light objects to fall slower than heavy ones.

In the real world, air resistance can cause a lighter object to fall slower than a heavier object of the same size. A tennis ball will reach the ground after a hard baseball is dropped at the same time. (It might be difficult to observe the difference if the height is not large.) Air resistance opposes the motion of an object through the air, while friction between objects, such as between clothes and a laundry chute or between a stone and a pool into which it is dropped, also opposes motion between them. For the ideal situations of these first few chapters, an object falling without air resistance or friction is defined to be in free-fall.

Derived quantities are derived from the Fundamental quantities and so the answer is Fundamental Quantity.

A quantity that has its own unit and is not derived from another is called a Fundamental quantity.

The given problem is based on the concept of Fundamental quantities. A fundamental quantity is a physical quantity which does not depends on any other quantities.

Fundamental quantities are the independent quantities which are utilized for the derivation of another type of physical quantities, known as derived quantities.

Thus, we can conclude that a quantity that has its own unit and is not derived from another is called a Fundamental quantity.

Explanation:

We are asked to find the potential energy of a bowling ball.

Potential energy is the energy an object possesses due to its position. It is calculated using the following formula.

[tex]E_p= mgh[/tex]

In this formula, m is the mass, g is the acceleration due to gravity, and h is the height.

The bowling ball has a mass of 2 kilograms. The hill is 5 meters high. Assuming this situation is occurring on Earth, the acceleration due to gravity is 9.8 meters per second squared.

Substitute the values into the formula.

[tex]E_p= (2 \ kg )(9.8 \ m/s^2)(5 \ m)[/tex]

Multiply the numbers together.

[tex]E_p=19.6 \ kg*m/s^2(5 \ m)[/tex]

[tex]E_p=98 \ kg*m^2/s^2[/tex]

Convert the units. 1 kilogram meter squared per second squared is equal to 1 Joule. Our answer of 98 kg*m²/s² is equal to 98 Joules.

[tex]E_p= 98 \ J[/tex]

The bowling ball has 98 Joules of potential energy.

A 2.00kg block is attached to a horizontal ideal spring with a spring constant k=100Nm.

The block-spring system is set on a horizontal surface with negligible friction.

Generally the equation for the Potential energy  is mathematically given as

[tex]P.E=\frac{1}{2}Rx_m^2\\\\2=\frax{1}{2}*100x_m^2\\\\x_m^2 = 0.04m\\\\x_m = 0.2m[/tex]

The PE is converted to KE, Therefore

[tex]KE = 2\\\\\frac{1}{2}MV_m^2 = 2\\\\V_m^2 = \frac{4}{M}\\\\V_m^2 = \frac{4}{2}\\\\V_m = \sqrt{2}\\\\V_m = 1.414m/s[/tex]
