The magnitude of the net torque on the wheel due to these three forces for an axis perpendicular to the wheel and passing through its center is

¹/₂MR³a.

Net torque on the wheel

The net torque on the wheel is determined from the moment of inertia of the pulley and the angular acceleration of the pulley.

∑τ = Iα

where;

Let the pulley be a solid uniform disk, the moment of inertia of the axis perpendicular to the wheel and passing through its center is calculated as;

I = ¹/₂MR²

τ = ¹/₂MR²α

τ = ¹/₂MR²(aR)

τ = ¹/₂MR³a

where;

Thus, the magnitude of the net torque on the wheel due to these three forces for an axis perpendicular to the wheel and passing through its center is ¹/₂MR³a.

If this wave has a frequency of 15 Hz then the wavelength of the wave would be  2 ×10⁷ m

It can be explained in terms of the separation between any two similar successive points on a wave, such as how the wavelength can be determined by calculating the separation between any two successive crests.

According to the following relation, the wavelength and wave frequency are inversely proportional.

C = νλ

Where c is the speed of light and v is the wave's frequency and λ

is the wave's wavelength.

As given in the problem If this wave has a frequency of 15 hz.

As we know C = νλ

by substituting the value of the frequency in the given formula

C = 3×10⁸ m/s

3×10⁸ = 15 ×λ

λ = 3×10⁸/ 15

  = 2 ×10⁷ m

Thus, If this wave has a frequency of 15 Hz then the wavelength of the wave would be 2 ×10⁷ m

Answer:

T = 2.4 + 2.4 = 4.8 [s]

Explanation:

In order to solve this problem, we must use the following kinematics equation and calculate the acceleration value.

[tex]x=x_{o} +v_{o}*t+(\frac{1}{2})*a*t^{2}[/tex]

Vo = inital velocity = 0

x - xo = 15 [m]

t = time = 2.4 [s]

15 = 0.5*a*(2.4)^2

a = 5.208 [m/s^2]

We can use the same equation to find the time.

30 = 15 + 0.5*(5.208)*t^2

t = 2.4 [s]

T = 2.4 + 2.4 = 4.8 [s]

Answer:

a. 720 yards

b. 254.56 yards

Explanation:

Given that the square block is 180 yards per side.

a. The distance traveled by John = The perimeter of the square block

  The perimeter of the square block = 4 x Length of one of its sides

So that,

The distance traveled by John = 4L

                                                   = 4 x 180

                                                   = 720 yards

Thus, John travels a distance of 720 yards.

b. John's final displacement = [tex]\sqrt{x^{2} +y^{2} }[/tex]

where x ad y are the length of any two sides of the square block.

John's final displacement = [tex]\sqrt{180^{2} + 180^{2} }[/tex]

                                           = [tex]\sqrt{64800}[/tex]

                                           = 254.5584

John's final displacement is 254.56 yards.

Answer:

[tex]a=0.125\ m/s^2[/tex]

Explanation:

Given that,

Mass, m = 40 kg

The net force with which Joyce pushes Efua is 5 N.

We need to find Efua’s resulting acceleration. Let it is equal to a. Net force is given by :

F = ma

[tex]a=\dfrac{F}{m}\\\\a=\dfrac{5\ N}{40\ kg}\\\\a=0.125\ m/s^2[/tex]

So, the acceleration is [tex]0.125\ m/s^2[/tex].

The resulting acceleration of Efua is  [tex]0.125 \;\rm m/s^{2}[/tex].

Given data:

The mass of Efua is, m = 40.0 kg.

The magnitude of applied force by Joyce is, F = 5.00 N.

The given problem is based on the Newton's Second law of motion. As per the Newton's second law, the applied force is equal to the product of mass and the acceleration of object. Therefore,

F = ma

a = F/m

Solving as,

a = 5.00 / 40

[tex]a = 0.125 \;\rm m/s^{2}[/tex]

Thus, we can conclude that the resulting acceleration of Efua is  [tex]0.125 \;\rm m/s^{2}[/tex].

Answer:

Trains displacement = 2.1 KM

Total distance covered by the train = 9.7 KM

Explanation:

Total distance covered by train will be the total distance moved train

hence

 total distance covered by the train = distance covered by train in positive direction +  distance covered by train in moving back

total distance covered by the train = 5.9 KM + 3.8 KM = 9.7 KM

_____________________________________

Displacement is the shortest distance from original position to the final position during the course of movement of any object.

Given that

Train moved 5.9 KM in positive direction(let it be AB as shown)

hence displace until now is 5.9 KM

but it again moved back for 3.8 KM(let it be B to C as shown below)

it means , train moved 3.8 KM towards origin position

so net displacement will be = 5.9 KM - 3.8 KM = 2.1 KM

A............................................................B ----> 5.9 KM

A_________C___________________B

                                 3.8 KM

Thus, AC will be displacement = AB - BC = 5.9 KM - 3.8 KM = 2.1 KM

Thus,

Trains displacement = 2.1 KM

Total distance covered by the train = 9.7 KM

Answer:

atom with a neutral charge is one where the number of electrons is equal to the atomic number. Ions are atoms with extra electrons or missing electrons. When you are missing an electron or two, you have a positive charge. When you have an extra electron or two, you have a negative charge.

Explanation:

When the amount of electrons in an atom is the same as the atomic number, the atom has a neutral charge. Particles with extra protons or missing electrons are known as ions.

Electrons are present outside the electron shell, in contrast to nucleons, which are contained inside the core at its center. Neg electrons are drawn to a positive nucleus so because excitons of opposite polarity attract one another. The total energy of an electron is inversely proportional to the intensity at which the electrons wave equation vibrates. Elevated atomic states have faster-vibrating electrons. An electron should always be oscillating at some speed because it is a subatomic object with wave-like characteristics.

Electrons are fundamental to many physical processes, including gravity, magnetic interactions, weak interrelations, electricity, magnetism, chemistry, and thermal conductivity. Ions and electrons are drawn into positive charges atoms by their nucleus's attraction pull. Unless an electrons received sufficient power to overcome this pressure by ascending, it was impossible for an electrons to escape from in an atom in mathematical mechanics.
