Answer: An element with 5 electrons is more likely to either gain 3  electrons in its’ outer-most valence electron shell

Explanation: To determine whether an element with 5 electrons is more likely to gain 3 or lose 5 electrons in its outermost valence electron shell, we can use the Lewis Dot Structure.

1. Draw the symbol of the element. For example, let's consider the element with 5 electrons as X.

2. Determine the number of valence electrons for the element. Since the element has 5 electrons, it will have 5 valence electrons.

3. Represent the valence electrons as dots around the symbol of the element. In this case, we would draw 5 dots around the symbol X.

4. Analyze the electron configuration to determine the stability of the element.

- If the element gains 3 electrons, it will have a total of 8 valence electrons. This would result in a stable electron configuration, similar to the nearest noble gas. For example, if the element is in Group 15, gaining 3 electrons would give it the electron configuration of the noble gas, Neon (2, 8).

The kangaroo's horizontal speed will be 9.7 m/s and its departure speed will indeed be 10.65 m/s.

By observing the pace at which this compressed region moves through the medium, we may determine the sound speed. The sound wave travels at a speed of around 343 meters per second in low humidity at 20 degrees Celsius.

The following equation relates the distance to the direction and initial velocity:

d = [v₀²sin2θ]/g, where θ – the angle of the jump.

Thus, v₀² = gd / (sin2θ) = (9.8×8)/0.69 = 113.62

v₀ = 10.65 m/s ( the take off speed).

The horizontal velocity equals:

Answer:

D = 104.4 m

Explanation:

We are given two displacement vectors. One in north direction other in east direction. We know that north and east directions are perpendicular to each other. Hence, the displacements vectors are also perpendicular to each other. Therefore, there resultant can be found by using Pythagora's Theorem like rectangular components method.

D = √(Dₓ² + Dy²)

where,

D = Magnitude of vector sum of both displacements = ?

Dₓ = Magnitude of Displacement Vector in east direction = 30 m

Dy = Magnitude of Displacement Vector in North Direction = 100 m

Therefore,

D = √[(30 m)² + (100 m)²]

D = 104.4 m

Image result for what does a worm and wheel mechanism do to torque and speed​

Like other gear arrangements, a worm drive can reduce rotational speed or transmit higher torque. ... Each full 360 degree turn of a single start worm advances the gear by one tooth. For a multi start worm the gear reduction equals the number of teeth on the gear divided by the number of starts on the worm.

we need to apply the principles of electromagnetism. When a conductor moves through a magnetic field, an emf (electromotive force) is induced in the conductor.

The magnitude of the emf is given by the product of the velocity of the conductor, the length of the conductor in the magnetic field, and the strength of the magnetic field. In this case, the metal rod is moving with constant velocity along two parallel metal rails, connected with a strip of metal at one end.

A magnetic field of magnitude B 0.350 T points out of the page. The rails are separated by L 25.0 cm and the speed of the rod is 55.0 cm/s.First, we need to determine the length of the conductor in the magnetic field. Since the rails are separated by L 25.0 cm, the length of the conductor in the magnetic field is also 25.0 cm.

Next, we need to determine the velocity of the conductor. The speed of the rod is given as 55.0 cm/s. Since the rod is moving along the rails, its velocity is perpendicular to the magnetic field. Therefore, we can use the speed as the magnitude of the velocity.

Now, we can calculate the magnitude of the emf using the formula: emf = velocity x length x magnetic field, emf = (55.0 cm/s) x (25.0 cm) x (0.350 T), emf = 481.25 mV, Therefore, the emf generated in the metal rod is 481.25 mV.

Plugging in the given values, we get: emf = 0.350 T * 0.25 m * 0.55 m/s, emf ≈ 0.0481 V, So, the generated emf is approximately 0.0481 volts.

The precessional angular speed Wp of the top while assuming that the moment of inertia of the thin cylinder is negligible is 11.23 rad/s.

In physics, quantitative measure of the rotational inertia of a body. It resists rotational motion and hence called moment of inertia and not moment of force.

How to calculate the precessional angular speed of Wp of the top?

Mass of cylinder, m = 13.3g

Length of the cylinder Lcyl = 6.8cm

The mass of the disk, M = 42g

The radius of the disk, Rdisk = 2.3cm

The center of mass is located at distance, dcom = 1.77cm

The angular speed of the top, w = 108 rad/s

The moment of inertia of the disk

I = 1/2 MRdisk^2

= 1/2 * 42 * 2.3^2

= 111.09 g cm^2

= 111.09 * 10^-3 * 10^-4 kg m^2

I = 1.11 * 10^-5 kg m^2

The moment of inertia is developed in the disk when it is rotating.

The precessional angular speed of the top formula is

Wp = Rdisk (M +m) *g / I*w

= 2.3 * 10^-2 * (42 * 10^-3 + 13.3 * 10^-3) * 9.8 / 1.11 * 10^-5 * 100

Protons/positive charges will move from higher potentials to lower potentials

While Electrons/Negative charges move from lower potentials to higher potential

Normally, electrons are negatively charged hence they tend to be repelled by the electrons and attracted by protons.

The right-hand rule is used in the field of electromagnetism. It is a method for determining the direction of a magnetic field related to the direction of the electric current that is creating it.

The right-hand rule is also used to determine the direction of the force on a charged particle moving in a magnetic field. There are two types of right-hand rules in electromagnetism: the right-hand rule for magnetic field direction and the right-hand rule for force direction. The correct statement regarding applying the right-hand rule is that if we hold a current-carrying conductor in the right hand, then the direction of the thumb points towards the direction of the current, then the curling of the fingers represents the direction of the magnetic field around the conductor. This means that if the current flow is in the upward direction in the conductor, then the magnetic field is in the counterclockwise direction around the conductor, and if the current is flowing in the downward direction, then the magnetic field is in the clockwise direction around the conductor. In the case of a loop conductor, we can determine the direction of the magnetic field inside the loop by using the right-hand rule. In this case, if we wrap the fingers of the right hand around the loop in the direction of the current flow, then the direction in which the thumb points gives us the direction of the magnetic field inside the loop. The right-hand rule is a very useful tool in understanding and visualizing the interactions between electric currents and magnetic fields. It is also an essential tool for designing and building electrical devices such as motors and generators. The right-hand rule is a fundamental concept in electromagnetism and is used extensively in many areas of science and engineering.

Answer: The position of the spring as a function of time is given by: x(t) = 6 * sin(π/4 * t)

where t is the time in seconds and x(t) is the position of the spring in meters.

Explanation:

The position of a spring as a function of time can be described by a sinusoidal function. The general form of such a function is:

x(t) = A * sin(ωt + φ) + x₀

where:

x(t) is the position of the spring at time t

A is the amplitude of the motion (maximum displacement)

ω is the angular frequency (related to the period T by ω = 2π/T)

φ is the phase angle (determines the starting point of the motion)

x₀ is the equilibrium position of the spring (where it would be at rest)

In this case, we know that the maximum displacement (amplitude) of the spring is 6m and the period T is 8s. Therefore, we can calculate the angular frequency ω as follows:

ω = 2π/T

ω = 2π/8

ω = π/4

We also know that the spring is at its equilibrium position when t = 0 (i.e., x(0) = x₀). Therefore, we can set x₀ to 0.

Finally, we need to determine the phase angle φ. This can be a bit tricky without more information, as there are many possible starting points for the motion that would produce a sinusoidal function with the given amplitude and period. For simplicity, we will assume that the spring is at its maximum displacement (positive direction) when t = 0. This means that the phase angle φ is 0.

Putting all of this together, we get:

x(t) = 6 * sin(π/4 * t)

This is the position of the spring as a function of time. It describes a sinusoidal motion with an amplitude of 6m and a period of 8s. The motion starts at the maximum displacement (positive direction) and oscillates back and forth around the equilibrium position (0).
