Explanation:

The loss caused by the induced currents that are produced in metal parts that are being magnetized is known as eddy current loss.

When a magnetic field moves around a conductor, such as a metal wire, it produces a voltage and a current in the wire. This is referred to as an induced current or an eddy current. These eddy currents cause energy to be dissipated in the form of heat, which results in a loss of energy. This loss of energy is referred to as eddy current loss.Therefore, the long answer to the given question is: The loss caused by the induced currents that are produced in metal parts that are being magnetized is known as eddy current loss.

-μ Fnorm = ma

(-μ) mg  = ma

(-μ) (g) = a

\(a = -(mu) g = -(0.41)(9.80 m/s^2) = -4.018 m/s^2\\\\v^2 = vinitial^2 + 2ax\\x = \frac{v^2 - vinitial^2}{2a} = \frac{0 - (23m/s)^2}{2(-4.018 m/s^2}\\x = 65.82877053 m\)

The distance required to stop by car is 65.96 m.

Given data:

The initial speed of Ke Min is, u = 23 m/s.

The mass of car is, m = 1200 kg.

The distance between the branch and Ke Min is, d = 60.0 m.

The coefficient of kinetic friction between the car’s locked tires and the road is, \(\mu =0.41\).

Here in the given problem, the frictional force will oppose the motion of the car. So, the linear force causing the acceleration is,

F = f

\(ma = -\mu \times m \times g\\\\a = -\mu \times g\\\\a = -0.41 \times 9.8\\\\a =-4.01 \;\rm m/s^{2}\)

Now, apply the third kinematic equation of motion to obtain the stopping distance (s) as,

\(v^{2} = u^{2} +2as\\\\0^{2} = 23^{2} +2(-4.01)s\\\\s = \dfrac{529}{8.02}\\\\s =65.96 \;\rm m\)

Answer:360 kg m/s

Explanation:Momentum refers to an object's quantity of motion.

Formula for Momentum: p=mv

p = refers to the momentum

m = refers to the object's mass (this is represented by the unit kg or kilogram)

v = this refers to the object's velocity (this is represented by the unit m/s or meter per second)

So, given that the bike has a mass of 18 kg and is traveling at 20 m/s, then you can already get the momentum by multiplying both of these values.

p = the bike's momentum (what is being asked here)

A 150.0 g hockey puck's momentum after 1.5 seconds of sliding due east at a speed of 10.0 m/s has a northward component of 7.5 kgm/s and an eastward component of 1.5 kgm/s.

Given mass of hockey puck (m) = 150g

speed due east (v) = 10m/s

Magnitude of force acting on it (F) = 5N

Time force exerted due north (t) = 1.5s

for the northward component Δp = FxΔt  where Δp = pf - pi is change in momentum, F is force and Δt denotes change in time.

pi = 0 ( As there is no momentum North )

pf = 5 * 1.5 = 7.5 kg m/s

For eastward component, we have p = mxv where m is mass and v is velocity.

There won't be any change in velocity because the force is acting perpendicular to velocity. Therefore, the eastward component's momentum does not change.

p = 0.15 * 10 = 1.5kgm/s

As a result, the northward and eastward components have corresponding momentums of 7.5 kg m/s and 1.5 kg m/s.

The magnitude of the emf induced between the two sides of the shark's head is 0.0448 mV.

It is defined as the generation of a potential difference in a coil as a result of changes in the magnetic flux through it. In simpler terms, electromotive force (EMF) is said to be induced when the flux linking with such a conductor or coil changes.

Electromotive forces can be produced in two ways.

The period of motion of the electron is 2.09 × 10^-6 seconds.

Period of motion can be defined as the time it takes for an object to complete one full cycle of its motion. In the context of circular motion, the period is the time it takes for an object to travel around a full circle and return to its starting position.

The period of motion, T, of an object moving in a circle can be calculated using the following formula:

T = 2πr/v

Where

In this case, the electron moves in a circular path with a radius of 0.20 m at a constant speed of 1.5 × 10^5 m/s. Plugging these values into the formula gives:

T = 2π(0.20 m) / (1.5 × 10^5 m/s)

T = 2.09 × 10^-6 s

The system described by the transfer function G(s) = -co² s² + 2a + w², with a damping ratio of 1.3 and a natural frequency of 0.5, has an overdamped unit step response. So, the correct option is (E)

The transfer function of the system is given as G(s) = -co² s² + 2a + w², where co represents the damping ratio, a represents an arbitrary constant, and w represents the natural frequency of the system. We are given that the natural frequency is 0.5 and the damping ratio is 1.3.

To determine the type of unit step response, we need to analyze the damping ratio (co) in relation to the critical damping value (co_critical).

The critical damping ratio (co_critical) is defined as the value where the system is on the threshold between being overdamped and underdamped. It is given by the formula co_critical = 2 * sqrt(a * w²).

In our case, the natural frequency (w) is 0.5, so we can calculate co_critical as follows: co_critical = 2 * sqrt(a * 0.5²).

Since the damping ratio (co) is given as 1.3, we can compare it with co_critical to determine the type of unit step response.

If co > co_critical, the system is considered overdamped (Option E).

If co = co_critical, the system is considered critically damped (Option D).

If co < co_critical, the system is considered underdamped (Option C).

Based on the given values, we can determine that the system is overdamped (Option E) because the damping ratio (1.3) is greater than the critical damping ratio.

The initial separation d between the mass and the spring is 0.14m.

A m = 2.88kg mass starts from rest and slides a distance d down a frictionless θ = 34.7° incline. While sliding, it comes into contact with an unstressed spring of negligible mass. The mass slides an additional 0.185m as it is brought momentarily to rest by compression of the spring (k = 409N/m).

The initial separation d between the mass and the spring can be calculated using the equation:

d = (2*m*g*sin(θ)) / k

Substituting in the given values, we get:

d = (2*2.88kg*9.8m/s2*sin(34.7°)) / 409N/m

d = 0.14m

Explanation:

The pressure at the point on the wing is \( P_1 - 18000 \text{ m}^2/\text{s}^2 \).The pressure at a point on the wing of the airplane can be calculated using Bernoulli's principle.

Bernoulli's principle states that as the velocity of a fluid (or air in this case) increases, the pressure decreases, and vice versa.

To calculate the pressure at this point on the wing, we need to use the equation:

\( P_1 + 0.5 \rho v_1^2 = P_2 + 0.5 \rho v_2^2 \)

where \( P_1 \) is the pressure at the standard altitude, \( v_1 \) is the velocity at the standard altitude, \( P_2 \) is the pressure at the point on the wing, and \( v_2 \) is the velocity at the point on the wing.

Given:

\( P_1 = \text{pressure at standard altitude} = ? \)

\( v_1 = \text{velocity at standard altitude} = 270 \text{ m/s} \)

\( v_2 = \text{velocity at the point on the wing} = 330 \text{ m/s} \)

\( \rho = \text{density of air} = \text{constant (we can ignore this for this calculation)} \)

We can rearrange the equation to solve for \( P_2 \):

\( P_2 = P_1 + 0.5 \rho v_1^2 - 0.5 \rho v_2^2 \)

Since we are not given the density of air, we can assume it to be constant and cancel it out from both terms. This simplifies the equation to:

\( P_2 = P_1 + 0.5 v_1^2 - 0.5 v_2^2 \)

Now we can substitute the given values and calculate \( P_2 \):

\( P_2 = P_1 + 0.5 (270 \text{ m/s})^2 - 0.5 (330 \text{ m/s})^2 \)

\( P_2 = P_1 + 0.5 \times 72900 \text{ m}^2/\text{s}^2 - 0.5 \times 108900 \text{ m}^2/\text{s}^2 \)

\( P_2 = P_1 + 36450 \text{ m}^2/\text{s}^2 - 54450 \text{ m}^2/\text{s}^2 \)

\( P_2 = P_1 - 18000 \text{ m}^2/\text{s}^2 \)

Therefore, the pressure at the point on the wing is \( P_1 - 18000 \text{ m}^2/\text{s}^2 \).

Please note that the actual value of \( P_1 \) is not given in the question, so we cannot provide a specific numerical answer. However, you can use this equation to calculate the pressure at any given point on the wing if the standard pressure at the standard altitude is known.

The electric field is a physical quantity that describes the force experienced by a charged particle in the presence of other charged particles. It represents the region around a charged object where it can exert a force on other charged objects.

The concept of the electric field was derived from Coulomb's Law, which states that the force between two charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

By analyzing the forces experienced by a test charge placed at different positions around a source charge, the electric field at each point can be determined.

Mathematically, the electric field (E) at a point is defined as the force (F) experienced by a positive test charge (q) divided by the magnitude of the test charge: E = F/q.
