Suppose a particle is undergoing circular motion in the xy plane, with the center of the circle at the origin.

The particle is moving at a constant speed, and is traveling counterclockwise around the circle. When the particle is moving to the left, the direction of the acceleration vector is towards Right (in the positive x-direction).

When a particle moves in a circular path, its velocity changes with time as it moves from one point to another. Because of this velocity change, the particle experiences acceleration. The direction of the acceleration vector points towards the center of the circle.

It is always perpendicular to the velocity vector of the particle at a given instant. The magnitude of the acceleration vector is given by the formula a = v²/r, where v is the speed of the particle and r is the radius of the circle. So, when the particle is moving to the left, its velocity vector will be directed towards the left.

The acceleration vector will be directed towards the center of the circle, which is towards the right. Therefore, the direction of the acceleration vector is towards Right (in the positive x-direction).

When a net impulse is applied to an object, it accelerates, its momentum changes, and its velocity also changes. Therefore, the correct answer is "i, ii, and iii" in the given group of answer choices.

a net impulse is applied to an object and it is not equal to zero, then all three statements are true: i. while the impulse is applied, the object accelerates, ii. the impulse causes a change in momentum of the object, and iii. while the impulse is applied, the object's velocity changes.
Impulse can be defined as the change in momentum of an object. Momentum is the product of an object's mass and its velocity. When a net impulse is applied to an object, it means that there is an external force acting on the object, causing it to accelerate. This acceleration results in a change in velocity.
Let's consider an example to illustrate this concept. Suppose you kick a soccer ball. The force of your kick is the impulse applied to the ball. The ball initially at rest accelerates due to the force applied and starts moving forward. This change in velocity shows that the object's velocity has changed. Additionally, as the ball moves, its momentum changes because its mass remains constant, but its velocity increases.

Answer:

Potential energy = 1.6 J

Work done = -1.6 J

Explanation:

Potential Energy in the spring at this extension?

The potential energy U in the spring is U = 1/2kx² where k = spring constant = F/x where F = force = 20 N and x = extension = 0.16 m. So k = 20 N/0.16 m = 125 N/m

U = 1/2kx²

= 1/2 × 125 N/m × (0.16 m)²

= 1.6 J

What is the work done to extend the spring. 16 meters

Work done W = U₁ - U₂ where U₁ = initial potential energy = 0 and U₂ = final potential energy = 1.6 J

W = 0 - 1.6 J

   = -1.6 J

The acceleration of the mass center is \(a = 7.857 rad / s^2\)

and the angular acceleration of the beam at this instant, \(a_{G} = 34.1 ft/ s^2\)

The mass moment of inertia of the beam :

Thus Ig  = 1/2 ml^2

this implies Ig = 1/2 ( 150/ 32.2 ) (12^2)

Thus the required value of Ig = 55.90 slug ft^2

Sigma f of x = m(a g)x

which is equal to Sigma f of x  = 21.47 ft/s^2 --------- 1

because 200 cos 60 = 150/ 32.2 (ag)x

and Sigma f of y = m a (g)y = 26.45 ft^2 --------2

because 200 sin 60 = 55.90α + 100(6)

The acceleration of the mass centre is a = 7.857 rad / s^2

Thus the magnitude of the acceleration is

aG = \(\sqrt{21.47^2+ 26.45^2}\)

aG = 34.1 ft/ s^2

The minimum period for a satellite in orbit around a spherical planet of uniform density can be derived by considering the gravitational force and the centripetal force acting on the satellite. By equating these forces, the minimum period can be determined.

The gravitational force acting on the satellite is given by the equation F_grav = (G * M * m) / r^2, where G is the gravitational constant, M is the mass of the planet, m is the mass of the satellite, and r is the distance between the center of the planet and the satellite.

The centripetal force required to keep the satellite in orbit is given by F_centripetal = (m * v^2) / r, where v is the velocity of the satellite.

By equating the gravitational force and the centripetal force, we have (G * M * m) / r^2 = (m * v^2) / r.

Simplifying the equation, we can solve for the velocity of the satellite, v, in terms of the gravitational constant, the mass of the planet, and the distance between the satellite and the planet.

The period of the satellite is given by the equation T = (2 * pi * r) / v, where T is the period and r is the distance between the center of the planet and the satellite.

By substituting the expression for v into the period equation, we can derive the minimum period for a satellite in orbit around a spherical planet of uniform density.

The poles of the electromagnet in an audio speaker switch directions due to the alternating current (AC) flowing through the wire coil wrapped around the magnet.

As the AC voltage changes direction, the magnetic field produced by the coil also changes direction, causing the electromagnet's poles to switch. This alternating magnetic field interacts with the permanent magnet in the speaker, causing the speaker cone to move back and forth, producing sound waves. The rapid switching of the poles allows for the speaker to reproduce complex sound signals with accuracy and clarity.

In the given series RLC circuit attached to a 120 V/60 Hz power line, the circuit draws a current of 2.80 A with a power factor of 0.830.

The power factor (PF) is the cosine of the phase angle (θ) between the voltage and current waveforms in an AC circuit. It indicates the phase relationship between the current and voltage and reflects the circuit's efficiency in utilizing the power.

To calculate the power factor, we need to determine the impedance (Z) of the circuit using the current (I) and the voltage (V) values. The power factor is then given by the ratio of the circuit's resistance (R) to its impedance (Z).

Given that the power factor is 0.830, we can determine the angle θ using the inverse cosine function: θ = arccos(PF).

Once we find the angle θ, we can calculate the impedance (Z) using the relationship: Z = V / I.

Knowing the impedance (Z) and the power factor (PF), we can then calculate the circuit's resistance (R) by multiplying the impedance by the power factor: R = Z × PF.

The form of energy stored in a stretched spring is elastic potential energy. When a spring is stretched or compressed, it possesses potential energy due to the deformation of its structure.

This potential energy is called elastic potential energy because it is associated with the elasticity of the spring.

As the spring is stretched, work is done to overcome the forces within the spring that resist the change in its length. This work is converted into potential energy, which is stored in the spring. The amount of potential energy stored in the spring is directly proportional to the amount by which it is stretched or compressed.

When two forces are simultaneously applied to a spring in opposite directions, it may result in elongation or contraction of the spring, depending on the magnitude and direction of the forces. If the applied forces are strong enough to overcome the spring's elasticity, the spring will undergo deformation and exhibit elongation or contraction. This deformation is a manifestation of the stored elastic potential energy being converted into mechanical energy.

Shear, bending, and intermolecular binding energy are not directly related to the stretching of a spring.

1.1 Nano-light-second means the path light traveled in 1.1 nanoseconds. We know that if an object has speed v, then the distance traveled by that object in time t, is given by, s=vt

So,

Time, t= 1.1 ns= 1.1×10⁻⁹ s

Speed of light, v= 2.998×10⁸ m/s

Hence distance traveled by light in that time is

s = vt

s = (2.998x10⁸ m/s) (1.1x10⁻⁹ s)

s = .32978 m

s = 32.978 cm
