Answer:

Only the third option has the same number of each size and color circles on either side of the arrow.

Explanation:

I believe it represents the dissolution of two molecules of hydrogen peroxide into two water molecules and an oxygen gas molecule.

The first one balances oxygen but changes sulfur with either carbon or nitrogen

The second one needs 5 oxygen gas pairs instead of a single one on the left to balance the right side. Represents oxidation of a propane molecule if given enough oxygen.

The fourth one has an extra nitrogen on the left side. The hydrogen is balanced. Making amonia.

The negative charge on the polyester ball is -1.53 x 10⁻⁶ C.

The given parameters;

The gravitational force on the ball is calculated as follows;

F = mg

F = 0.012 x 9.8

F = 0.12 N

The electrostatic force on the ball is calculated as follows;

[tex]F= \frac{kq^2}{r^2} \\\\q^2 = \frac{Fr^2}{k} \\\\q = \sqrt{\frac{0.12 \times (0.42)^2}{9\times 10^9}} \\\\q =+/ -\ \ 1.53 \times 10^{-6} \ C\\\\q =-\ \ 1.53 \times 10^{-6} \ C[/tex]

Thus, the negative charge on the polyester ball is -1.53 x 10⁻⁶ C.

It will take 6.42 s for the ball that is dropped from a height of 206 m to reach the ground.

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

Height (H) = 206 m

NOTE: Acceleration due to gravity (g) = 10 m/s²

The time taken for the ball to get to the ground can be obtained as follow:

H = ½gt²

206 = ½ × 10 × t²

206 = 5 × t²

Divide both side by 5

[tex]t^{2} = \frac{206}{5}\\\\ t^{2} = 41.2[/tex]

Take the square root of both side

[tex]t = \sqrt{41.2}[/tex]

Therefore, it will take 6.42 s for the ball to get to the ground.

TDS and ppm are common units used to measure the quantity of substance in the water, therefore the correct answer is option A.

A unit of measurement is a specified magnitude of a quantity that is established and used as a standard for measuring other quantities of the same kind. It is determined by convention or regulation.

Common units used to measure the amount of material in water are TDS and part per million.

As given in the problem we have to find out for what measurement, the units TDS (Total dissolved solid )and ppm (parts per million) are used.

The total dissolved solid and parts per million are used to measure the amount of substance present in the water, therefore the correct answer is option A.

Explanation:

The equilibrium condition allows finding the results for the forces of the system are

      a) The free body diagram is in the attachment

      b) The normal force is N = 737 N

      c) The mass of the table is  10.2 kg

Newton's second law indicates that the net force is proportional to the product of the mass and the acceleration of the bodies, in the special case that the acceleration is zero, it is called the equilibrium condition

          ∑ F = 0

Where the bold letters indicate vectors, F is the external forces

a) A free body diagram is a scheme of the forces without the details of the bodies, in the attachmentt we see a free body diagram of the system.

b) The reaction force of the ground is applied in each of the legs of the table, in general this force has the same magnitude in each leg, therefore in Newton's second law we can place it as a single force

             N = N₁ + N₂ + N₃ + N₄₄

Let's apply the equilibrium condition

                N -  [tex]W_m -w_{table}[/tex] = 0

                N =  [tex]W_m +w_{table}[/tex]

                N = [tex]M_m g + w_{table}[/tex]  

They indicate the pose of the boy is 65 kg, for the weight of the table of a laboratory table is approximately 100 N

                N = 65 9.8 + 100

                N = 737 N

c) To calculate the mass of the table we use the relation

                W = [tex]m_{table}[/tex] g

                [tex]m_{table} = \frac{w_{table}}{g}[/tex]

                [tex]m_{tabble}= \frac{100}{9.8}[/tex]  

               [tex]m_{table}[/tex]e = 10.2 kg

In conclusion using the equilibrium condition we can find the results for the forces are

      a) The free body diagram is in the attachment

      b) The normal force is N = 737 N

      c) The mass of the table is  10.2 kg

Explanation:

If v(t) is speed measured in meters per second (m/s), and t is time measured in seconds (s), then the constants A and B in

v(t) = At ³ - Bt

must have units of m/s⁴ and m/s², respectively; otherwise, the equation is dimensionally inconsistent.

[m/s] = A [s]³ - B [s]

[m/s] = [m/s⁴] [s]³ - [m/s²] [s]

[m/s] = [m/s] - [m/s]

[m/s] = [m/s]

Hi there!

We can begin by calculating the total WORK done using the equation:

Power · time = Work

650 · 15 = 9750 J

We know that:

Work = Force · displacement (W = Fd), so:

W/d = F

9750/30 = 325 N

Answer:

[tex]\boxed {\boxed {\sf 875 \ Joules}}[/tex]

Explanation:

Kinetic energy is the energy an object possesses due to motion. It is calculated using the following formula:

[tex]KE= \frac{1}{2}mv^2[/tex]

The mass of the person is 70 kilograms and they are moving at a speed of 5 meters per second.

Substitute these values into the formula.

[tex]KE= \frac{1}{2} (70 \ kg )(5 \ m/s)^2[/tex]

Solve the exponent.

[tex]KE= \frac{1}{2}(70 \ kg)(25 \ m^2/s^2)[/tex]

Multiply the numbers in parentheses.

[tex]KE= \frac{1}{2} (1750 \ kg*m^2/s^2)[/tex]

Multiply by 1/2 or divide by 2.

[tex]KE= 875 \ kg*m^2/s^2[/tex]

Convert the units. 1 kilogram meter squared per second squared is equal to 1 Joule. So, our answer of 875 kg*m²/s² is equal to 875 Joules.

[tex]KE= 875 \ J[/tex]

The person has 875 Joules of kinetic energy.

Acceleration is the rate at which the velocity changes .

The molecular mass, in atomic mass unit, of aspartame would be 294 amu while the mass, in kg, of an aspartame molecule would be 0.294 kg

Aspartame has the chemical formula C14H18N2O5

C = 12, H = 1, N = 14, O = 16

(a) Molecular weight = (12x14) + (1x18) + (14x2) + (16x5)

                                  = 168 + 18 + 28 + 80

                                    = 294 amu

(b) Mass of 1 molecule of aspartame = mole x molar mass

                                    = 1 x 294

                                        = 294 g

Converting 294 g to kg = 294/1000

                                         = 0.294 kg
