What budget item does not necessary include expense

in the two cases shown the mass and the spring are identical but the amplitude of the simple harmonic motion is twice as big in

Ira Lisetskai [31]

The maximum velocities in the two cases related are Vmax,2 = 2 Vmax,1

Simple harmonic motion :

In physics, simple harmonic motion is the repeated back-and-forth motion through an equilibrium, or center, position so that the maximum displacement on one side of this position is equal to the maximum displacement on the other. Each whole vibration occurs at the same time interval.

Complete question:

In the two cases shown the mass and the spring are identical but the amplitude of the simple harmonic motion is twice as big in Case 2 as in Case 1.

1)How are the maximum velocities in the two cases related?

Vmax,2 = Vmax,1

Vmax,2 = 2 Vmax,1

Vmax,2 = 4 Vmax,1

a lion is stalking an antelope that is running at a speed of 7m/s. At the moment the antelope passes the lion, she gives chase a

fiasKO [112]

Antelope: uniform motion => V = d/t => d = Vt = 7m/s * t

Lion: uniformly accelerated motion, with initial velocity = 0 => d = [1/2]a*t^2 = [1/2]*[5m/s^2]*t^2

7*t = 2.5*t^2=> 2.5t^2 - 7t =0 => t(2.5t - 7) = 0

2.5t - 7 = 0 => t = 7/2.5 = 2.8 m/s^2

A particular coaxial cable is comprised of inner and outer conductors having radii 1 mm and 3 mm respectively, separated by air.

noname [10]

Answer:

The value is $\rho_s = 4.026 *10^{-6} \ C/m^2$

Explanation:

From the question we are told that

The radius of the inner conductor is $r_1 = 1 \ mm = 0.001 \ m$

The radius of the outer conductor is $r_2 = 3 \ mm = 0.003 \ m$

The potential at the outer conductor is $V = 1.5 kV = 1.5 *10^{3} \ V$

Generally the capacitance per length of the capacitor like set up of the two conductors is

$C= \frac{2 * \pi * \epsilon_o }{ ln [\frac{r_2}{r_1} ]}$

Here $\epsilon_o$ is the permitivity of free space with value $\epsilon_o = 8.85*10^{-12} C/(V \cdot m)$

=> $C= \frac{2 * 3.142 * 8.85*10^{-12} }{ ln [\frac{0.003}{0.001} ]}$

=> $C= 50.6 *10^{-12} \ F/m$

Generally given that the potential of the outer conductor with respect to the inner conductor is positive it then mean that the outer conductor is positively charge

Generally the line charge density of the outer conductor is mathematically represented as

$\rho_l = C * V$

=> $\rho_d = 50.6*10^{-12} * 1.5*10^{3}$

=> $\rho_d = 7.59*10^{-8} \ C/m$

Generally the surface charge density is mathematically represented as

$\rho_s = \frac{\rho_l }{2 \pi * r_2 }$ here $2 \pi r = (circumference \ of \ outer \ conductor )$

=> $\rho_s = \frac{7.59 *10^{-8} }{2* 3.142 * 0.003 }$

=> $\rho_s = 4.026 *10^{-6} \ C/m^2$

In the space below, write one sentence describing how particles move in a longitudinal wave. Then, write two more sentences desc

kupik [55]

Answer:

First statement: The particles which are displaced is parallel to the direction of energy transport or to the direction the wave travels.

Second statement: amplitude is measured by determining how far the molecules of the medium have been displaced from their normal rest position.

Third statement: wavelength is measured through determining the distance between one point on the wave and the corresponding point on the next one.

Explanation:

Wave can be defined as a displacement that occurs in a medium, from one point to another. There are two different kinds of waves in physics which includes:

- Longitudinal wave and

- Transverse wave.

In a longitudinal wave, particles are displaced parallel to the direction of energy transport or to the direction the wave travels. There are also different properties which can be used to describe a longitudinal wave and they includes:

- amplitude: amplitude is measured by determining how far the molecules of the medium have been displaced from their normal rest position in a longitudinal wave.

- wavelength is measured through determining the distance between one point on the wave and the corresponding point on the next one.
