What is Newton's third law motion answer part a and b

The wavelength and frequency of the second harmonic are 24 cm and 720 Hz, respectively, and the speed of each wave is 17280 cm/s.

In general, the frequency, wavelength, and speed of a wave are related by the equation:

v = fλ

where v is the speed of the wave, f is the frequency, and λ is the wavelength.

For the third harmonic, we know that f = 360 Hz and λ = 48 cm. Using the above equation, we can solve for the speed of the wave:

v = fλ = (360 Hz)(48 cm) = 17280 cm/s

Now, for the second harmonic, the wavelength will be half of the third harmonic wavelength, i.e., λ = (1/2)48 cm = 24 cm. To find the frequency of the second harmonic, we can use the same equation as before:

f = v/λ = (17280 cm/s)/(24 cm) = 720 Hz

Answer:

Different ions of an element

Explanation:

From the options given, it is only the different ions of an element that can have different electrons.

This is because ions carry charge which could be positive or negative due to a deficit or excess of electrons.

A cation would be formed if there is a deficit of electrons and the atom becomes positively charged, and an anion would be formed if there is an excess of electrons and the atom becomes negatively charged.

For different ions of the same element, the electron number would vary and this would thus lead to each different ion carrying a greater or lesser charge than the other ions of the same element.

Different numbers of electrons occurs in different ions of an element.

Different isotopes of an element have the same number of number of protons and electrons but different number of neutrons.

Different ions of an element have different number of electrons.

For cations, such as;

Thus, we can conclude that different numbers of electrons occurs in different ions of an element.

The matter in the accretion disc is heated to extremely high temperatures, which ultimately lead to the emission of photon radiations, as the speed of the infalling particles becomes more random or chaotic.

We are aware that disordered microscopic particle motion, as defined, is thermal motion and is hence directly related to temperature. The most significant features in the universe are accretion discs, which can be found even in tight binary stars, surrounding smaller stars or stellar remnants, in spiral galaxy centers, in quasars, and they can even form in gamma-ray bursts. The shape of the accretion disc might vary. It could be planar or spherical.

They are bumping into other gas particles as they move. As a result, the movement's direction changes, and it now moves randomly. Particles that are travelling at random make up gas.

The minimum angle the rope can make with the horizontal is approximately 74.12 degrees.

To find the minimum angle the rope can make with the horizontal, we need to consider the tension in the rope. The tension in the rope can be divided into vertical and horizontal components.

In this case, the tension in the rope is given as 1,800 N, and the weight of the tightrope walker is given as 500 N. The vertical component of tension must balance the weight of the tightrope walker:

Vertical component of tension = weight of the tightrope walker

Tension * cos(θ) = weight

1,800 N * cos(θ) = 500 N

Solving for cos(θ):

cos(θ) = 500 N / 1,800 N

cos(θ) ≈ 0.278

Now, we can find the minimum angle θ by taking the inverse cosine (arccos) of 0.278:

θ ≈ arccos(0.278)

θ ≈ 74.12 degrees

Therefore, the minimum angle the rope can make with the horizontal is approximately 74.12 degrees.

RS is a composition of rotation and reflection in the Euclidean plane E². The precise description of RS depends on the specific properties of the rotation R and reflection S.

In general, if R and S have the same axis or line of symmetry, the composition RS results in a translation. If R and S have intersecting lines of symmetry, RS yields a glide reflection. If R and S have perpendicular lines of symmetry, RS produces a rotation.

It is important to consider special cases, such as parallel lines of symmetry, coinciding axes, or perpendicular lines of reflection, as they may lead to different outcomes.

Answer:

The monkey hit the pond after approximately \(0.55\; {\rm s}\) in the air.

The monkey hit the pond approximately \(1.1\; {\rm m}\) away from the base of the cliff.

(Assume that \(g = 9.81\; {\rm m\cdot s^{-2}}\), air resistance on the monkey is negligible, and the cliff is vertical.)

Explanation:

Assume that the air resistance on the monkey is negligible. The vertical acceleration of the monkey would be constantly \(a_{y} = (-g) = (-9.81)\; {\rm m\cdot s^{-2}}\). Note that \(a_{y}\) is negative since the monkey is accelerating downwards.

Right before hitting the pond, the monkey would be \(1.5\; {\rm m}\) below the cliff. Hence, the vertical displacement \(x_{y}\) of the monkey would be \((-1.5)\; {\rm m}\).

Let \(u_{y}\) denote the initial vertical velocity of the monkey. Since the top of the cliff is level, initial velocity will be entirely horizontal. Hence, \(u_{y} = 0\; {\rm m\cdot s^{-1}}\).

Let \(t\) denote the amount of time it took for the monkey to hit the pond (\(t \ge 0\).) Rearrange the SUVAT equation \(x_{y} = (1/2)\, a_{y}\, t^{2} + u_{y}\, t\) and solve for \(t\!\).

Since \(u_{y} = 0\; {\rm m\cdot s^{-1}}\), the equation simplifies to:

\(x_{y} = (1/2)\, a_{y}\, t^{2}\).

\(\begin{aligned}t^{2} = \frac{2\, x_{y}}{a_{y}}\end{aligned}\).

Since \(t \ge 0\):

\(\begin{aligned}t &= \sqrt{\frac{2\, x_{y}}{a_{y}}} \\ &= \sqrt{\frac{(2)\, (1.5\; {\rm m})}{(9.81\; {\rm m\cdot s^{-2}})}} \\ &\approx 0.553\; {\rm s}\end{aligned}\).

Hence, it would take approximately \(0.55\; {\rm s}\) for the monkey to hit the pond.

Also because air resistance on the monkey is negligible, the horizontal velocity \(v_{x}\) of the monkey will be constantly equal to the initial value \(2.0\; {\rm m\cdot s^{-1}}\).

Hence, the monkey would have travelled a horizontal distance \(x_{x}\) of:

\(\begin{aligned} x_{x} &= v_{x}\, t \\ &\approx (2.0\; {\rm m\cdot s^{-1}})\, (0.553\; {\rm s})\\ &\approx 1.1\; {\rm m}\end{aligned}\).

According to the question the speed of the skater's hands is 528 m/min.

To calculate the speed of the skater's hands, we can use the formula:

Speed = Circumference * Revolutions per minute

Given that the skater's hands are 140 cm apart and she spins at 120 rpm, we need to calculate the circumference of the circle formed by her hands.

The circumference of a circle is given by the formula:

Circumference = 2 * π * radius.

In this case, the radius is half the distance between the skater's hands, which is 140 cm / 2 = 70 cm.

Converting the radius to meters, we have 70 cm = 0.7 m.

Now we can calculate the circumference:

Circumference = 2 * π * 0.7 m = 4.4 m (rounded to one decimal place).

Finally, we can calculate the speed of the skater's hands:

Speed = Circumference * Revolutions per minute

     = 4.4 m * 120 rpm

     = 528 m/min.

Therefore, the speed of the skater's hands is 528 m/min.

1/R = 1/R₁ + 1/R₂ + 1/R₃

1/R = 1/4 + 1/6 + 1/10

On solving, R = 1.9 Ω

Now, the Equivalent resistance(R) of parallel combination is in series with r = 2Ω

Let Equivalent resistance of Series combination be R'

R' = R + r

R' = 1.9 + 2 Ω

R' = 3.9 Ω

Explanation:

A diode, which allows current to flow in one direction only, consists of two types of semiconductors joined together.

A semiconductor can be defined as a crystalline solid substance that has its conductivity lying between that of a metal and an insulator, due to the effects of temperature or an addition of an impurity. Semiconductors are classified into two main categories;

1. Extrinsic semiconductor.

2. Intrinsic semiconductor.

An intrinsic semiconductor is a crystalline solid substance that is in its purest form and having no impurities added to it. Examples of intrinsic semiconductor are Germanium and Silicon.

In an intrinsic semiconductor, the number of free electrons is equal to the number of holes. Also, in an intrinsic semiconductor the number of holes and free electrons is directly proportional to the temperature; as the temperature increases, the number of holes and free electrons increases and vice-versa.

In an intrinsic semiconductor, each free electrons (valence electrons) produces a covalent bond.
