The displacement (in meters) of a particle moving in a straight line is given by the equation of motion s = 8 t2 , where t is measured in seconds. Find the velocity (in m/s) of the particle at times t = a, t = 1, t = 2, and t = 3.

Answers

Answer 1

The velocity of the particle is 0 m/s since the displacement is 0 when t = a.

What is the velocity ?

Velocity is a measure of the rate and direction of change in the position of an object. It is a vector quantity, consisting of both speed and direction. Velocity is most commonly expressed in terms of distance traveled per unit of time. The average velocity of an object over a period of time is its displacement divided by the time duration. Speed, on the other hand, is a scalar quantity and is the magnitude of the velocity vector. It is the rate of change in position of an object, regardless of direction.

Answer 2

The velocity variates different at different time i.e. when

t = 1, v = -16m/s

t = 2, v = -2.25m/s

t = 3, v = -1.77m/s

What is Velocity?

The concept of velocity refers to the rate and direction of motion of a point. For instance, the orientation of a circular path is always perpendicular to the line that connects a point to the center of the circle. A point always advances down a route that is perpendicular to it (a radius). The magnitude of the velocity is the rate of motion of the point along its path through time.

If a point moves along a path and covers a certain distance in a predetermined amount of time, its average speed over that period of time is equal to the distance covered divided by the travel time. For instance, the average speed of a train traveling 100 kilometers in two hours is 50 km/h.

v(t) =ds / dt = d(8/t²) / dt = -16/t³

Velocity of the particle at time t = a

v(a)= - 16 / a³

Velocity of the particle at time t = 1

v(1) = -16m/s

Velocity of the particle at time t = 2

v(2) = -2.25m/s

Velocity of the particle at time t = 3 v(3) = - 1.77m/s

Eccentricity is a measure of how much an ellipse deviates from a perfect circle. It is defined as the ratio of the distance between the two foci of an ellipse to the length of its major axis. The eccentricity of a circle is zero, while any other ellipse has an eccentricity greater than zero but less than one. Eccentricity is used to quantify how elongated an ellipse is, with higher eccentricity indicating a more elongated shape. Eccentricity can also be used to describe the orbits of planets and other celestial bodies, with higher eccentricity indicating a more elongated orbit.

Hints remaining: 2 Feedback: deduction per feedback.

Answers

The electric flux through the loop is approximately 3.42 newton squared meters per coulomb (N·m^2/C).

The electric flux through a surface is given by the product of the electric field passing through the surface and the area of the surface,

Φ = EAcos(θ)

where Φ is the electric flux, E is the electric field, A is the area of the surface, and θ is the angle between the electric field and the normal to the surface.

In this problem, the electric field is parallel to the x-axis, so its angle with the normal to the circular loop is θ = 55°.

The area of the circular loop is A = πr^2, where r is the radius of the loop. Thus, the electric flux through the loop is:

Φ = EAcos(θ)

= (42 N/C)(π(0.24 m)^2)*cos(55°)

An element crystallizes in a face-centered cubic lattice and has a density of 1. 456 g/cubic. The edge of its unit cell is 4. 52 x 10-8 cm. What is the mass of a unit cell ?.

Answers

The mass of a unit cell is 6.65 x 10⁻²³ g.

What is mass?

Mass is a measure of the amount of matter in an object. It is a scalar quantity, meaning it has only magnitude and no direction. Mass is often used interchangeably with weight, although they are different concepts. While mass is a measure of the amount of matter in an object, weight is the force exerted on an object due to gravity.

The mass of a unit cell can be calculated using the formula:

mass = density x volume

The volume of a face-centered cubic (FCC) unit cell can be calculated as follows:

volume = (edge length)^3

Substituting the given values, we get:

volume = (4.52 x 10⁻⁸ cm)³ = (4.52 x 10⁻⁸)³ cm³ = (4.52 x 10⁻²⁴) cm³

And the mass of a unit cell is:

mass = density x volume = 1.456 g/cm³ x 4.52 x 10⁻²⁴ cm³ = 6.65 x 10⁻²³g

So the mass of a unit cell is 6.65 x 10⁻²³ g.

As a result of the upward lift (buoyancy), of course, objects that are in the liquid will experience a weight reduction. As a result, objects lifted in water will feel lighter than when lifted on land.

Concepts related to force include thrust, which increases the velocity of an object; drag, which decreases the velocity of an object; and torque, which produces changes in the rotational speed of an object. In an extended body, each part usually applies forces on the adjacent parts; the distribution of such forces through the body is internal mechanical stress.

Answers

The tension needed to tune a grand piano string with a frequency of 27.5 Hz and a length of 1.90 m is 5,129 N.

The tension required to tune the string can be calculated using the following formula:

Where T is the tension, mu is the string's linear mass density (mass per unit length), v is the wave's speed on the string, and L is the span of the string's vibrating portion.

To begin with, we must figure out the string's linear mass density:

mu = m/L = 0.440 kg/1.8 m = 0.2316 kg/m

The speed of the wave on the string needs to be calculated next. The equation: gives the speed of a wave on a string.

sqrt(T/u),

T represents tension, and u represents linear mass density. This equation can be changed to:

T = u

The tension required to tune the string can be calculated using the following formula:

T = (mu * v^2) / L

Where T is the tension, mu is the linear mass density of the string (mass per unit length), v is the speed of the wave on the string, and L is the length of the vibrating section of the string.

First, we need to calculate the linear mass density of the string:

mu = m / L = 0.440 kg / 1.90 m = 0.2316 kg/m

Next, we need to calculate the speed of the wave on the string. The speed of a wave on a string is given by the formula:

v = sqrt(T/u)

where T is the tension and u is the linear mass density. Rearranging this equation gives:

T = u * v^2

Substituting in the values we have:

v = f * lambda

where f is the frequency and lambda is the wavelength of the wave. The wavelength can be calculated from the length of the vibrating section of the string:

lambda = 2 * L = 3.80 m

Substituting in the values we have:

v = f * lambda = 27.5 Hz * 3.80 m = 104.5 m/s

Now we can calculate the tension:

T = u * v^2 / L = 0.2316 kg/m * (104.5 m/s)^2 / 1.90 m = 5,129 N

Therefore, the tension needed to tune this string properly is 5,129 N.
